The maximum volume setting is a safety precaution that limits the maximum volume that can be achieved by spinning the wheel or increasing volume via the remote. This can be set to protect your loudspeakers against overload.

Default Volume

The default volume setting controls the default volume when the TDAI-2210 is switched on.

Sound: RoomPerfect™

Introduction to RoomPerfect™

RoomPerfect™ is designed to analyse and correct for the negative effects that the listening room has on the speaker’s sound.

It is very challenging to design a perfect listening environment with a symmetrical setup and an ideal reverberation time, especially without vibrating surfaces like windows. A traditional speaker setup requires uneven distances to the back and side walls to avoid reflections arriving at the listening position simultaneously, as this would have a negative effect on the frequency response. Having strong reflections after each other will cause “smearing” of the sound and reduce the overall dynamic performance.

Focus position

The focus filter improves the sound quality at a specific listening position. This makes the focus filter the best solution for optimal sound quality at a single listening position. A total of 8 focus positions can be stored after the initial calibration.

Global filter

The global filter enhances sound quality throughout the entire room. When moving around a room, the global filter yields the best results.

Note: For more detailed information, FAQs, and videos about RoomPerfect, please visit our website.

How to Set Up RoomPerfect™

Note: The RoomPerfect™ microphone is a highly sensitive and finely calibrated device which must be treated with utmost care. If the microphone has been dropped on the floor, it may be damaged. If this is the case, obtain a new microphone from your Lyngdorf Audio representative before performing the system calibration.

RoomPerfect™ Preparations

• Place the RoomPerfect™ calibration microphone on the stand. Be sure to fasten the screws properly so the microphone does not move during a measurement.

• Plug the supplied microphone cable into the microphone.

• Connect the microphone cable to the TDAI-2210 using the included mini-jack connector.

Placing the Microphone in the Focus Position

When prompted to place the microphone in the focus position, connect the microphone to the microphone input on the front of the TDAI-2210 and position the microphone, using the microphone stand, in your primary listening position. The height and the orientation of the microphone should correspond to your head’s height and direction.

Volume Setting

Press Enter, and a test signal will start from the left speaker. The system will give an estimated optimal volume for calibrating the system, or will accept the current volume. Adjust the volume if required by the system and retry the measurement.

The calibration volume should not be so loud that it is inconvenient to you or causes damage to your loudspeakers. If this is the case, set it to a lower and more appropriate level. A low volume can result in a longer calibration time or a measurement time-out. A low volume and long measurement will not affect the quality of the result.

If the system continues to require a higher signal level, the problem could be a defective adaptor, cable or microphone.

Measuring the Focus Position

When the calibration volume has been set, RoomPerfect™ will send a range of pure tones to measure the focus position. If there is noise in the room, the measurement may take longer to complete. This will not affect the quality of the result.

Measuring Random Room Positions

When the focus position has been measured, the next step is to measure the acoustical properties of the room. It is essential to perform well-spaced measurements to obtain a comprehensive image of the room’s acoustical properties. See RoomPerfect™ troubleshooting if the measurement stops prematurely.

Keep taking measurements until RoomKnowledge reaches 90%.

Note: RoomKnowledge refers to the level of new information in the last measurement. If there is little new information, the system will interpret it as meaning it knows nearly everything. When the RoomKnowledge does not increase after a measurement, this means that the measurement provided a lot of new information to the calibration!

These are the guidelines when measuring the room:

• The microphone should be in random and varying positions, heights, and orientations.

• Point the microphone up/down/sideways – the more random positions the better.

• The measurements should cover the primary listening area.

• Do not take measurements behind plants, furniture, etc.

• The microphone should not be closer than 0.5m/1.5ft from the floor, ceiling, and walls.

• The microphone should be at least 1m/3ft from the front of the loudspeakers.

• There should be at least 50cm/1.5ft between each measurement.

• Do not take symmetrical measurements in the room.

To fully optimise the system’s understanding of the room’s acoustical properties, we recommend you continue taking measurements until the RoomKnowledge is above 95%. The higher the RoomKnowledge, the more accurate the room correction filters will be.

Note: The RoomKnowledge is calculated from the amount of NEW information in the measurement compared to the data already stored. It is therefore the target to have as SLOW an increase in RoomKnowledge as possible.

Calculation of Focus and Global Filters

Once the room measurements are complete, the system will automatically calculate the focus and global filters.

Note: We recommend saving a Backup of TDAI-2210 settings after performing a RoomPerfect™ calibration (see “Manage Software” in the Setup section).

Sound: Output Settings

The Output setup allows you to select and customise speakers and woofers, and to set up the analogue and digital pre-outs.

The frequency graphics and connections diagrams on the touchscreen or in the app will help you to find the right crossovers, EQ, and levels.

Warning:

Both the + and – speaker outputs of the TDAI-2210 carry voltage.

Never run the TDAI-2210 in Bridge Mode with another amplifier!

Never connect the speaker outputs to the high-level inputs of a subwoofer amplifier!

Setup

The Setup menu offers three different options:

• Standard

• Custom

• Preamp

Standard

Standard is for a classic 2-channel stereo setup with two loudspeakers, left and right.

Select Generic for any kind or brand of loudspeaker.

Select one of the Lyngdorf speaker models to optimise the sound performance. This will add an equalising filter designed for the selected speaker.

Custom

Custom is for speaker-subwoofer systems and other individual speaker setups.

Select Generic for any kind or brand of loudspeaker.

Select one of the Lyngdorf speaker models to optimise the sound performance with an equalising filter designed for this speaker when used together with the subwoofer chosen next.

Select No Subwoofers if you are only using two loudspeakers.

Select Custom Subwoofers if you are using 1 or 2 Subwoofers together with the loudspeakers. Next, select how the subwoofer is amplified by selecting Generic Amplifier or choosing one of the Lyngdorf amplifiers. Next, select the connection method you have used for the amplifier, such as RCA, XLR, or Digital. Next, set a crossover frequency between speakers and subwoofers.

Note: The default crossover frequency is 80 Hz. It can be changed in the following steps. The ideal frequency is determined by the frequency response of the loudspeakers and the subwoofer’s frequency response.

Preamp

Preamp is for using the TDAI-2210 as a pre-amplifier, music streamer, or RoomPerfect™ processor.

Note: The power amp section (speaker outputs) will be disabled when using the TDAI-2210 in Preamp mode.

You can set the analogue output and the digital output individually to match your system as follows:

Output Off

Output is not used. No signal at the output.

Full Range

Provides the complete frequency signal with volume regulation, tone controls, Voicings, and RoomPerfect™ calibration.

Low Pass

Provides only lower frequencies with volume regulation, tone controls, Voicings, and RoomPerfect™ calibration.

High Pass

Provides only higher frequencies with volume regulation, tone controls, Voicings, and RoomPerfect™ calibrated.

Tape Out / Line Out

Provides the complete frequency signal with no volume regulation (full signal level), no tone controls, no Voicings, no RoomPerfect™ calibration.

Headphone Amplifier

Provides the complete frequency signal with no volume regulation (full signal level), tone controls, Voicings, and no RoomPerfect™ calibration.

Distance

When a speaker-subwoofer system is set, Distance allows for aligning different distances of speakers and woofers in relation to the listening position.

Measure the distance between the primary listening position (listener’s head) and the front of the left and right speakers, and type in the number in cm or inches.

Measure the distance between the primary listening position (listener’s head) and the back corner of the subwoofer, and type in the number in cm or inches.

The difference will then be automatically aligned in the DSP (Digital Signal Processor), so that speakers and woofers integrate as well as possible.

Verify

Use Verify to check whether all speakers and woofers are set up and connected correctly.

This function will first play a signal on the left speaker, then on the right speaker, and then on the woofers (if configured).

Increase the volume level so that you can clearly hear the signal, then verify and compare all channels.

If you miss one signal, first check all connections and wires. Second, check whether the selected speaker setup and woofer setup in the Output menu match your actual speaker system.

Main menu

The Main output menu sets the crossover, level, and sound EQ for the main speakers.

Crossover

Routing

• Full-range: Allows the incoming signal to pass unfiltered.

• High pass: Removes frequencies below the crossover frequency, allowing high frequencies to pass.

• Low pass: Removes frequencies above the crossover frequency, allowing low frequencies to pass.

Frequency

The number sets the crossover frequency for the routing in Hertz.

The ideal frequency is determined by the frequency response of the loudspeakers and the subwoofer’s frequency response. For traditional setups, the frequency should be the same for both Main and Preout outputs.

Filter

• LR 2nd, 4th or 8th order.

• BW 1st, 2nd or 4th order.

The references “LR” and “BW” refer to the inventors of modern crossover designs, Linkwitz-Riley and Butterworth. The filter order refers to how the high-pass and low-pass outputs interact with each other, as well as the steepness of the filter curve. The curve shown in the app or touchscreen will indicate the characteristic.

Level

Reduce the signal level for the main speaker output by up to 24 dB to match the level of the pre-output.

Speaker EQ

You can select any of the built-in equaliser filters or choose “Custom” to design your own filter and optimise the sound from your speakers.

A custom speaker EQ is optional and only required if your speaker lacks internal crossover filters or if you wish to modify the sound of your speakers.

Advanced: Analogue Out and Digital Out

The Analogue and Digital output menu sets the crossover filter, level, amp delay, signal, and sound EQ for the analogue or digital pre-out. The default setting for the analogue and digital output is Off.

Crossover

• Full Range: allows the signal to pass unfiltered.

• High pass: Removes frequencies below the crossover frequency, allowing high frequencies to pass.

• Low pass: Removes frequencies above the crossover frequency, allowing low frequencies to pass.

Frequency

The number sets the crossover frequency for the routing in Hz.

The ideal frequency is determined by the frequency response of the loudspeakers and the subwoofer’s frequency response. For traditional setups, the frequency should be the same for both the Main and Pre-out outputs.

Filter

• LR 2nd, 4th or 8th order.

• BW 1st, 2nd or 4th order.

“LR” and “BW” refer to the inventors of common crossover designs, Linkwitz Riley and Butterworth. The filter order refers to how the high-pass and low-pass outputs interact with each other, as well as the steepness of the filter curve. The curve shown in the app or touchscreen will indicate the characteristic.

Level

Level reduces the signal level for the main speaker output by up to 24 dB to match the levels of the pre output.

Amp Delay

Amp Delay takes care of the signal delay (latency) of external amplifiers.

For example, if you have an active subwoofer with internal signal processing (DSP) or a separate Amplifier with internal A/D or D/A conversion, there may be an electronic signal delay in these products.

Request the internal signal delay (latency) in milliseconds (ms) of the connected amplifier, active subwoofer, or DSP from the manufacturer, and type in the number in Amp Delay. This will time-align the main speakers with the pre-out, leading to better sound integration.

Level Control

Full scale

The pre-out gives the full signal level from the audio source, independent of the volume control.

Regulated

The pre-out follows the volume control level set for the main speaker outputs.

Signal Output

Mono

The pre-out will provide a mono signal.

Stereo

The pre-out will provide a stereo signal.

Speaker EQ

You can select any of the built-in equaliser filters or choose “Custom” to design your own filter and optimise the sound from your speakers or subwoofer.

Advanced: 2nd Speaker Setup

Add a 2nd Speaker Setup

Here you have the option to store a second speaker setup. This will allow you to test another speaker setup or to store and keep two calibrated setups for general use – for example, with and without a subwoofer.

Enabling this will initiate the Guided Speaker Setup and RoomPerfect™ calibration for the second speaker setup.

Once complete, the Speaker Setup menu item will be available in the main menu, enabling you to switch between the two setups easily.

Tips for Setting Up Speakers

Stereo Triangle

You can use the stereo triangle as a good rule of thumb when determining where to place your speakers. The distance between the speakers should be the same as the distance from your listening position to both speakers.

Tip: You can reduce reflections from the hard floors and hard surface walls by positioning a carpet, painting, a bookshelf, or other furnishings between you and the speakers. These objects act as diffusers.

Find the position of the diffusers by having someone hold a mirror flat against the wall or floor. When you can see the speaker in the mirror from the listening position, you have found the optimal position for the diffuser.

Speaker Placement / Traditional Box Speakers

For an optimal listening experience with a RoomPerfect™ calibration, we recommend placing your speakers against the wall, opposite your preferred listening position. This will ensure that the wall reflection and the direct sound reach your ears simultaneously, giving you perfect timing and impulse response.

If your speakers have a bass-reflex port on the back, allow a 5 cm / 2 inches clearance to the back wall. This will ensure that there is no disruption to the port’s functionality.

Subwoofer Placement

With a single subwoofer, we recommend placing the subwoofer against the wall between the main speakers.

With two subwoofers, position one in each front corner, aligned with the main speakers.

Note: As the TDAI-2210 now controls the Phase, Cut-Off Frequency, and Level, you should set the controls of the connected subwoofer(s) to neutral:

• Phase: 0,
• Cut-Off: Maximum, and
• Level at 50% of maximum.

When connecting the Lyngdorf boundary woofers, you should connect the analogue outputs to the BYPASS input of the woofer.

Measuring Distances

When measuring the distance to your main speakers, measure from the preferred listening position (the focus position) to the front of the speakers.

When measuring the distance to a subwoofer, measure from the preferred listening position to the back corner of the subwoofer.

Note: Always perform a new RoomPerfect™ calibration when you have changed speaker or subwoofer placement, or changed settings in the Output setup.

Sound: Headphones

Startup sets a default volume level.

Max limits the maximum volume level, for example, to prevent high levels from damaging the headphones.

Mute at power on if headphones are connected. This function allows you to control whether the headphone connector should control the mute function on your speakers.

Sound: Polarity Inversion

Polarity inversion is equal to changing + and – on the cables to the loudspeakers. You can do this individually for each speaker.

Sound: Enhancements

ICC (Intersample Clipping Correction)

Can be set to enabled or disabled.

Digital audio tracks typically exceed 0 dBFS (decibels relative to full scale), which means they will be clipped when upsampled or otherwise processed in the audio chain, resulting in distortion.

With ICC enabled, the TDAI-2210 will dynamically provide extra headroom to prevent clipping during the processing of the audio signal.

Changing inputs or going into standby mode will reset the ICC level.

Subsonic Filter

The subsonic filter can be set to enabled or disabled.

A subsonic filter, also known as a rumble filter, is a high-pass filter that cuts frequencies below 20 Hz. It can be used to prevent a turntable and the woofers or subwoofers from influencing each other.

For example, LPs can have warps which cause the woofer to have a large excursion in the subsonic frequencies below 20 Hz. Turntable placement, room vibrations, and floor vibrations can cause a similar effect.

Since frequencies below 20 Hz are not easily audible, activating the subsonic filter can prevent excessive woofer excursion, reduce distortion, increase amplifier efficiency, and enhance overall sound performance.

Software

Updates

In this menu, you will see the current software version on the TDAI-2210 and show an update, if available.

Note: If the web interface is inaccessible or a fault in the update process has rendered the amplifier inaccessible, you can force a new software update onto the TDAI-2210.

Forced Software Update

1. Save the new software on a FAT-formatted USB drive.

2. Insert the USB drive into the “SW Update” connector on the back of the TDAI-2210.

3. Turn off the TDAI-2210 by disconnecting the mains power on the back of the device.

4. Hold down the standby button on the front and connect the mains power again.

5. When the Lyngdorf logo starts flashing, release the standby button, and the TDAI-2210 will update the software. When the update is complete, the amplifier enters standby mode.

Data

Backup

When a USB device is inserted into the connector on the rear of the TDAI-2210, this menu allows you to store a complete backup of settings, including the RoomPerfect™ calibration. This will enable you to restore the amplifier to this specific setup at a later date.

Note: You can store several Backups. Ensure you enter distinct backup file names to differentiate between versions.

Restore

If a backup file is available on a USB medium, you can select and load it.

System

Reboot

Sets the TDAI-2210 to standby mode and then restarts it. This process closes all running programs and resets the system to its last state and settings.

Reset UI

Resets the user interface, screen and cache to default settings.

Factory Reset

Shuts down the system and returns to default factory settings.

Warning: All user preference settings, system data, and RoomPerfect™ data are lost when restoring to default settings! To keep the settings, choose Reboot.

The Factory reset is also possible over the front panel. If you press and hold the Standby button for more than five seconds and then release it, the TDAI-2210 will initiate a factory reset.

If you have pressed the Standby button for more than five seconds by mistake, you can avoid the factory reset by holding the Standby button for an additional five seconds. This will skip the factory reset initiation.

Voicings: How to select and set up Voicings

A Voicing is a sound-equalising filter that can be activated to amplify or attenuate certain frequencies according to your personal preferences. A Voicing can be set for the TDAI-2210 in general, and assigned to each input individually, for example, emphasise bass on one input without sacrificing neutrality on others.

Voicings

The TDAI-2210 comes with 14 Voicing presets.

The names and the shown equalising curves indicate the sound character.

Neutral

Default Voicing with no change in tonal balance.

Music

Dampens the midrange to compensate for recordings that would otherwise sound too harsh.

Music 2

Further dampens the midrange and removes harshness.

Relaxed

Dampens the low and midrange frequencies.

Open

Dampens the low frequencies.

Open Air

Further dampens the low frequencies.

Soft

Dampens upper tones slightly, making bright tracks warmer and more balanced.

Action 1

Enhances the lower frequencies.

Action 2

Further enhances the lower frequencies.

Movie

Dampens the high frequencies.

Action Movie

Enhances the lower frequencies and dampens the high-range frequencies.

News

Cuts low frequencies for live broadcasting, sports, and news, while improving speech intelligibility.

Bass 1

Enhances the lower frequencies and dampens the midrange to compensate for recordings that would otherwise sound too harsh.

Bass 2

Further enhances the lower frequencies and dampens the midrange to remove harshness.

Creating Custom Voicings

A Voicing can combine up to eight filter sections. For each section, you can choose from various filter designs, which, when combined, will provide the total correction of the Voicing.

For each Voicing, you will see a green line showing the total correction, as well as a blue line showing the correction caused by the selected filter section. If there is only one active filter section, only the blue line is shown. You can choose between the following filter designs:

Low Pass

Functions as a crossover filter, reducing the signal above the frequency.

High Pass

Functions as a crossover filter, reducing the signal below the frequency.

Low Shelf

Attenuates the lower frequencies to a specified level.

High Shelf

Attenuates the higher frequencies to a specified level.

Parametric

Attenuates a specific frequency.

All these filters can have either positive or negative gain, effectively reversing the filter’s effect.

You can adjust the Overall gain for each Voicing to switch between Voicings without experiencing a change in perceived volume level.

Try experimenting by creating your own Voicings and testing the functionality of the different filter sections.

Exporting and Importing Voicings

It is possible to download single Voicings to a file and to add new Voicings by uploading those files as well.

This will enable copying a Voicing from one device to another. The file format is identical for all enabled Lyngdorf products, so if you have a Voicing you like on your TDAI-2210 amplifier, it is possible to add that to your Lyngdorf multichannel processor or vice versa.

You can also download and upload an entire set of Voicings. Again, these files will work on all devices that support this feature.

Note:

Uploading a set of Voicings with this feature will replace all Voicings in the amplifier.

Single Voicing files have the extension single_voicing.xml, and this must not be changed.

Editing or deleting Voicings

The Voicings dropdown list contains all the Voicings currently stored in the amplifier. Selecting a Voicing in the list will allow you to delete or edit the selected Voicing (this will open the Voicing editor).

Adding a new Voicing

To create a new custom Voicing using the Voicing editor, enter the name of your new Voicing and tap Add.

To add a Voicing from a single_voicing.xml file, browse for the file and then tap Add.

Replacing all Voicings from file

This functionality replaces all Voicings in the amplifier with a new set from a voicings.xml file.

Please note that this will overwrite all Voicings currently stored in the amplifier. Click “Browse” to find the voicings.xml file you wish to upload, and then tap Apply to use it.

At the bottom of the page, you will find a link to download the current set of Voicings in the amplifier to a voicings.xml file.

To view the details for a stored Voicing, select it and tap Edit. You can also delete the stored Voicings and add new designs here.

HDMI

What is CEC?

Consumer Electronics Control (CEC) is an HDMI feature that allows you to command and control CEC-enabled devices connected through HDMI using a single remote control (for example, adjusting the volume level on the TDAI-2210 utilising the TV’s remote control).

The level of CEC implementation depends on the manufacturer of each product, and even if a device is brand new, not all electronic devices support CEC. As the television is the “CEC master” in an HDMI setup, the CEC implementation of the television will determine what is possible for the entire system.

CEC

Enables and disables CEC (Consumer Electronics Control) over HDMI.

HDMI TV Audio Input

Switches to the selected input upon detecting an HDMI Audio signal

Note:

By default, CEC is not activated on HDMI to comply with stand-by power regulations. CEC functionality only works with the TDAI-2210 set in Network Stand-By.

CEC is marketed by manufacturers under individual names and designed to promote the connection to the same brand sources. (SONY: Bravia Link, Panasonic: Viera Link, etc.)
