Initial Setup Procedure

Set up the TDAI-3400 integrated amplifier by following these steps:

  1. Connect the speakers to the Speaker Output connectors.
  2. Connect all external equipment, audio and video, mains power, etc. to the TDAI-3400.
  3. If possible, connect the TDAI-3400 to your local network with an ethernet cable.
  4. Switch on the mains switch on the back of the TDAI-3400.
    • The TDAI-3400 will boot the internal computer and go into Stand-By.
  5. Switch on the TDAI-3400.
  6. The TDAI-3400 will initially want to connect to your local network
    • If connected by network cable (LAN) the TDAI-3400 will automatically connect and display the IP network reference.

For using iPhone or iPad

If no wired network is attached, the TDAI-3400 will want to connect via WIFI – referring to “Apple Wi-Fi Accessory Configuration”.

For using Android phone or tablet

The TDAI-3400 will establish a soft access point. Type 192.168.110.42 in your browser to access the manual Wi-Fi setup.

Without iPhone/iPad you can manually enter all data or use the WPS function to pair the TDAI-3400 with your Wi-Fi router. (Select WPS and go and press the WPS button on your router)

You can now choose to continue the setup via the display or via web interface (see next page).

If you at any point do not want to continue doing setup or calibration, then exit the menu by a long push on the menu button. The TDAI-3400 will now have a basic stereo setup, and you can play music.

Home Screen / IP Interface

Installation and Operation via IP Interface

With the TDAI-3400 connected to your local network, on the remote press INFO twice to reveal the IP address allocated by the router. Open a browser and write the IP address to access the TDAI-3400.

If you are using an apple product you can also access the device by entering http://tdai3400.local/ in your browser.

As default the TDAI-3400 will use a dynamic IP address. If you want to use a static IP address, you can set this at any time in the Network Setup menu.

If the TDAI-3400 is still in initial setup, you will be guided through the procedure just like on the display operation.

The HOME screen refers to the daily operation as performed with the remote control. The page displays selected input and formats and you can control the volume setting.

The HEADPHONES section can be accessed, when a pair of headphones are connected to the TDAI-3400 on the front panel connector. Here you can adjust volume settings and mute the output.

The SETUP section will be described in the following pages.

The interface for controlling the built-in media streamer is found in the bottom section of this page. For information as to the use of the interface see section for Streaming Setup.

Hot tip: On your mobile device the Home Screen page of your amplifier can be saved as an icon for swift access to operation of the TDAI-3400.

Input Setup

In the Input setup menu, you can adjust the settings for the signal coming from each input.

Input name

You can change the name to refer to the equipment connected to the input.

Enable input

Enables and disables individual inputs so you do not have to scroll through unused inputs.

Enable theater mode

Turns the amplifier into a dedicated power amplifier for the source to this input. This feature bypasses the volume control. This feature might be selected if you are using the TDAI-3400 in a home theater setup where it is used to power and calibrate the front speakers and/or subwoofer. Connect your home theater processor to the selected input. When selecting other inputs, the amplifier returns to the last current volume.

Warning:

Do NOT test this setting with a CD player or similar unregulated signal! In this mode the TDAI-3400 will get very hot, why good ventilation is required!

Sensitivity

Enables you to match the levels of other inputs. Can be adjusted up to +24dB.

Voicing

Select the default voicing. See later section for designing voicings.

Input delay (Lipsync offset)

Set delay time in milliseconds to ensure that the video and audio signals are played back simultaneously.

Preset vTuner station

When selecting vTuner Internet radio stations for presets, they will automatically appear as inputs. (The interface for controlling the built-in media streamer with vTuner is found in the bottom section of the HOME page)

Note:

To save changes, you must press “Save” after making changes to a single input. Do not go to the next input before saving changes.

Output Setup

Lyngdorf Web UI Setup Output

The output setup menu will display the recommended filter settings from the selection of speakers and subwoofer from your initial Guided Speaker Setup. In this section you can change the setup of speaker and line level outputs to your preferences.

Selecting a Lyngdorf speaker will load an equalizing filter designed to optimize the performance of this speaker in relation to the selection of sub speaker selected. Selecting “Custom” will open new settings allowing you to design your own equalizing filter.

In order to reveal all directly controlled features, select CUSTOM speakers and ADVANCED under LINE output selection!

Lyngdorf Web UI Setup Output 2

Main speakers

Select the design of speakers connected to the speaker (Main) outputs of the TDAI-3400.

Line out / Sub speakers

Select the design of (Sub-) woofers handling the lower frequencies connected to the analog or digital outputs of the TDAI-3400. Analog and digital outputs can have their individual setup of the output – select ADVANCED for Line out to reveal options.

Add 2nd speaker setup

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

Enabling this will start the Guided Speaker Setup for the 2nd speaker setup. When complete, the menu item Speaker Setup will be available in the main menu, allowing you to easily switch between the two setups.

WARNINGS:

Never run the TDAI-3400 in Bridge Mode with another amplifier!

Never connect speaker cables to High Level Inputs of a subwoofer!

Enable limiter

Normally increasing the volume setting of any amplifier above the nominal specification will allow for higher levels – just with higher distortion levels. Enabling the limiter will ensure that no matter the overall volume setting, the output stage of the TDAI-3400 will never exceed specified distortion levels.

Routing

The available settings are:

Level

Reduce the signal level for this output with up to 24 dB to match the levels of other output channels.

Eq

Select any of the built-in equalizer filters or select “custom” for designing your own filter to optimize the sound from your speakers. See the chapter Voicings, for input as to the design of filters.

Filter

Sets the type of crossover filter to be applied to this output.

Filter Type

Sets the type of crossover to be applied to this output.

The references LR and BW refers to the inventors of modern crossover designs. The filter order refers to how the high pass and low pass outputs interact with each other. This subject is too complicated to describe in detail in this manual. We refer to external literature for further information.

Frequency (Hz)

Sets the crossover point for the filter type selected. For traditional setups the frequency should be the same for both Main and Line outputs.

Verify speaker setup

This function will send out a signal to each speaker for verifying the wiring against the chosen setup.

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 you place your speakers against the wall, opposite from your preferred listening position. This will ensure the wall reflection and the direct sound will reach your ears at the same time, giving you perfect timing.

If your speakers have a bass-reflex port on the back, you should allow for a 5cm/2in clearance to the back wall. This will ensure there is no disruption to the functionality of the port.

Subwoofer placement

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

With two subwoofers, you should position one in each front corner, in line with the main speakers.

Note:

As the Phase, Cut-Off Freq. and Level is now controlled by the TDAI-3400, you should set the controls of 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 analog 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.

Always perform a new RoomPerfect™ calibration when you have changed settings in the Output setup.

Introduction to RoomPerfect™

It is very difficult to design a perfect listening environment with a symmetrical setup and a perfect reverberation time without vibrating surfaces like windows. A traditional setup of speakers requires uneven distances to back and side walls to avoid having the reflections arrive to the listening position at the same time, as this would have a negative effect to the frequency response. Having strong reflections after each other is though causing smearing of the sound and reduces the overall dynamic performance.

RoomPerfect™ is designed to analyze and correct for the negative effects that the listening room has on the speaker sound. Correcting the frequency response only, the setup of speakers should focus on having the optimal dynamic performance by positioning all speakers as close to the back wall as possible – and the sub(s)preferably into the front corners of the room

Other correction systems will at their best offer a range of target curves for the calibration, whereas RoomPerfect™ will identify the sound properties of your speakers and use these for the calibration.

RoomPerfect™ is therefore not just an equalizer, but in fact the only true room correction system.

If you want to change the target curve (the tonal balance of your speakers) for the calibration, you can enter your own pre-eq filter design under the Output Setup. Through a new calibration process, RoomPerfect™ will then clean up the new tonal balance.

Global filter

The global filter improves sound quality across the whole room. When you are moving around a room, the global filter gives the best result.

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.

See our website www.lyngdorf.com for more detailed information.

RoomPerfect™ Setup

The RoomPerfect™ microphone is a very 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

Placing the Microphone in the Focus Position

When you are prompted to place the microphone in the focus position, connect the microphone to the microphone input on the front of the TDAI-3400 and place 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 that it 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 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. This will not affect the quality of the result.

See RoomPerfect™ troubleshooting if the measurement stops prematurely, and then retry the measurement.

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 important to perform well spaced measurements to get a comprehensive image of the acoustical properties of the room. See RoomPerfect™ troubleshooting if the measurement stops prematurely.

Keep taking measurements until RoomKnowledge reaches 90%.

Note:

RoomKnowledge relates to the level of new information in the last measurement – if there is little new information, the system will translate it to the fact that it knows nearly everything. When the RoomKnowledge does NOT increase after a measurement, it means that the measurement gave a lot of new information to the calibration!

These are the rules of thumb when measuring the room:

Lyngdorf RoomPerfect Measuring Side View

Side view of room

Lyngdorf RoomPerfect Measuring Top View

Top view of room

To fully optimize the systems understanding of the room’s acoustical properties, we recommend you keep doing measurements until the RoomKnowledge is above 95%. The higher the RoomKnowledge, the more accurate the room correction filters will be.

Calculation of Focus and Global Filters

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

Notes:

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

We recommend that you ALWAYS take a backup of TDAI-3400 settings after having performed a RoomPerfect™ calibration (see Manage Software in the Setup section).

Voicing Setup

Lyngdorf Web UI Setup Voicing

A voicing is an equalizer filter that can be activated to amplify or attenuate certain frequencies according to your personal preferences. For each Source you can dedicate a Voicing, meaning that you can emphasize bass on one input without sacrificing neutrality on others.

Exporting and Importing Voicings

It is now possible to download single voicings to a file and to add new voicings by uploading those files as well. This will make it possible to copy 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-3400 amplifier, it is possible to add that to your Lyngdorf multichannel processor or vice versa.

Note:

Single voicing files have the extension single_voicing.xml and this may not be changed.

You can also download and upload an entire set of voicings. Again, these files will work throughout the devices which support this feature.

Note:

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

Files with an entire set of voicings have the extension .voicings.xml and this must not be changed

Edit or delete voicing

This dropdown list contains the voicings currently 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)

Add new voicing

To create a new voicing using the voicing editor, enter the name of your new voicing and press add.

To add a voicing from a single_voicing.xml file, browse for the file and then press add.

Replace all voicings from file

This is the functionality to replace all voicings in the amplifier with a new set from a .voicings.xml file. Remember that this will overwrite all voicings currently in the amplifier. Click browse to find the .voicings.xml file you wish to upload and then press Apply to use it.

On the bottom of the page is a link to download the current set of voicings in the amplifier to a .voicings.xml file.

Through selecting any of the stored Voicings, you can see the details by selecting EDIT. You can also delete the stored Voicings and add new designs here.

Creating Voicings

A Voicing can combine up to eight filter sections. For each section, you can choose between certain filter designs, which then in combination will give you the total correction of the Voicing.

For each Voicing you will see a green line showing the total correction as well 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 select between following filter designs:

All these filters can be with positive or negative gain – effectively reversing the effect of the filter.

You can adjust the Overall gain for each voicing in order to be able to switch between voicings without experience any change in perceived level.

Lyngdorf Web UI Voicings

In this example (Action Movie Voicing) you will see the combined effect of two filter sections:

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

Audio Setup

ICC (Intersample Clipping Correction)

ICC can be set to enabled or disabled.

Digital audio tracks normally exceed 0 dBFS (decibels relative to full scale), why they will be clipped when being up sampled or otherwise processed in the audio chain resulting in distortion. With ICC enabled the TDAI-3400 will dynamically allow for extra headroom to avoid clipping during processing the music. Changing inputs or going into standby mode will reset the ICC level.

Hot Tip: Press INFO on your remote to see the signal level of the present audio input. It is a peak-meter and will be reset, when you switch input.

Show RoomPerfect™ bypass

If you want to discover what effect the calibration has had on your sound, you can activate a bypass function, which now can be selected on your remote control.

Mute at power on if headphones are connected

This function allows you to control, if the headphone connector should control the mute function on your speakers.

Main volume control / Headphones volume control

These settings control the overall output through your main speaker system / headphone output

Maximum volume

The maximum volume setting is a safety precaution used for limiting the maximum volume which 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 at start-up.

HDMI Setup

What is CEC?

Consumer Electronics Control (CEC) is an HDMI feature designed to allow you to command and control CEC-enabled devices that are connected through HDMI, by using only one of the remote controls (for example, controlling the volume level in the TDAI-3400 by using the remote control of the TV).

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

Enable CEC

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

HDMI output

When enabled, this feature will send the current digital stereo signal though the HDMI cable to the TV.

This feature requires that the digital output has been configured under the Output Setup menu. The digital output should be set to Full-range and Full-scale.

Notes:

As default, CEC is not activated on HDMI to comply with stand-by power regulations. CEC functionality only works with the TDAI-3400 set in Network Stand-By.

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

Troubleshooting

RoomPerfect™

The calibration microphone is very sensitive and may pick up unwanted noise, including subsonic signals and background noise, which disturbs the measurements. If the signal is disturbed, it will take longer for the system to make a correct measurement.

A measurement that has been disturbed by noise but completed will always be correct; it is not necessary to redo it. If the measurement has stopped due to an error, one of the error messages below will be shown.

Error Messages

No microphone connected

No microphone is connected, or the microphone cable is not working. Check that the microphone cable is connected to the microphone socket on the back panel. If the problem continues, test the microphone cable by connecting the microphone directly to the microphone socket and select Retry.

If the microphone is detected, replace the microphone cable and retry the measurement.

Fault – No signal

This error message can arise due to a signal classification of no sound. This happens if the sound volume has been muted or a cable is disconnected.

If none of these measures solve the error, request a replacement microphone from Lyngdorf Audio.

Fault – Signal clipping

Either the incoming signal has been classified as too loud, resulting in clipping or distortion, or a loud noise in the immediate environment has corrupted the measurement results. If a loud noise has in fact occurred, such as the sound of a closing door, reduce noise levels inside and in the immediate vicinity of the room and repeat the measurement. If no loud noise has occurred, reduce the volume of the signal and repeat the measurement.

Fault – Low signal

This error message is displayed when the measurement has lasted more than 5 minutes for the low-frequency signal or more than 2 minutes for the high-frequency signal. This happens most often when using a low-level measuring signal compared to the background noise in the listening environment, which results in prolonged measuring times. Raise the measuring signal volume or reduce the noise in the environment before continuing with the measurement.
