How to get started
Before you connect the TDAI-1120 to mains power, you need to connect loudspeakers and other sources of
audio. If you have a local network, the connection by wire is recommended, as it provides more stable and
faster network connection than Wi-Fi.
The TDAI-1120 holds a wide range of connectors on the back for external audio sources in addition to the
streaming options available through Bluetooth or your network.
1. A1/PHONO MM: Connects directly to turntables/gramophones with high output cartridges (MM: Moving
Magnet). The ground cable from the turntable/gramophone connects to the finger screw.
2. A2/ANALOG IN: Connects to tape recorders and other analog sources.
3. OUT: Connects to subwoofer(s), tape recorders, external amplifiers or headphone amplifier.
4. MICROPHONE: Connects to the microphone and microphone cable for RoomPerfect™ calibration.
5. D1-D2 COAXIAL DIGITAL INPUTS: Connects to CD players and other digital sources.
6. D3-D4 OPTICAL DIGITAL INPUTS: Connects to CD players and other digital sources.
7. USB: Connects to your FAT32 formatted USB storage (Pen Drive or Network Attached Storage, NAS).
This connector can also power the external storage drive or other devices.
8. HDMI OUT: (No video output) Connects to your Televisions HDMI ARC connector for playing TV sound.
9. TRIGGER IN/OUT: These connectors allow you to have the TDAI-1120 activated by another product – or

Tips for setting up speakers
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.
If your room does not accommodate the optimal listening
setup, the TDAI-1120 can compensate for this, when you
enter the actual distances to each speaker through the
Speaker Setup Guide.
Speaker placement with RoomPerfect™
With a RoomPerfect™ calibration available, you can place the speakers up against the wall without negative
effects to the sound.
If your speakers have a bass-reflex port on the back, you should though allow for a 5cm/2in clearance to the
wall. This will ensure there is no disruption to the functionality of the port.
Connecting a subwoofer
The TDAI-1120 features a crossover function for optimal integration with any subwoofer.
When connecting to a Lyngdorf BW type subwoofer, you connect the analog output of the TDAI-2170 to the
BYPASS input of the subwoofer.
In a traditional single subwoofer setup, connect the subwoofer to the left analog output on the TDAI-1120.
For a stereo subwoofer setup, or if you have a subwoofer which has stereo input, use both left and right
analog outputs.
Warning: Do not connect the TDAI-1120 to a subwoofer with High Level /
speaker terminal inputs, as this will seriously damage the amplifier.

Lyngdorf Audio TDAI-1120 – Owner’s manual

Subwoofer controls
1. Phase adjustment should be 0°.
2. The subwoofer cut-off frequency should be set to the
highest possible frequency range.
3. Level should be set to 50% of the maximum.
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.

Turning on the TDAI-1120 for the first time
When you connect the TDAI-1120 to mains power, the Lyngdorf logo on the front will be blinking through-out
the start-up process. When the logo stops blinking, the TDAI-1120 is ready for operation and can play audio
from external sources
Network connection by cable (recommended)
If the TDAI-1120 is connected to your network by cable, you can now access the TDAI-1120 by the Lyngdorf
Remote Application for IOS and Android devices, and you can stream to the TDAI-1120 from your music
applications.
Establishing Wi-Fi connection
The TDAI-1120 can be connected to your Wi-Fi network both through a simple iPhone/iPad functionality
(WAC mode) or by using the manual WPS functionality on routers.
Procedure with iPhone or iPad (WAC):
If the TDAI-1120 was not connected by cable, the Wi-Fi symbol on the front will be flashing quickly
The TDAI-1120 now appears on all your apple devices in the Wi-Fi section of Settings . When selected
the Wi-Fi settings will be transferred from your iPhone/iPad to your TDAI-1120.

4.1.5 Home theater
Turns the amplifier into a dedicated power amplifier for the input which is active when in this menu. .
Warning: This feature bypasses the volume control!
Do not test this setting with a CD player or similar unregulated signal!
This feature might be selected if you are using the TDAI-1120 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.
4.1.6 Lipsync delay
If the connection of a display has introduced asynchronous playback of audio and video, you can select a
delay time in to ensure that the video and audio signals are played back simultaneously.
4.2 RoomPerfect™ setup
4.2.1 RoomPerfect™ guide
This will start the guided RoomPerfect™ setup and will erase previously stored calibrations. When
completed, the following menu items are available in the RoomPerfect™ setup menu.
4.2.2 Status
This screen shows how many room measurements have been made, together with the Room Knowledge
and Room Correction index.
The Room Knowledge index is an estimate of how much of the room’s acoustical properties have been
learned from the room measurements. The higher the Room Knowledge index, the greater the accuracy of
the calibration.
Hot Tip: The objective is to have the Room Knowledge index to increase as slowly as
possible. This indicates that each measurement holds new data for the calibration. When
the measurement does not give new data, the index will increase quickly.

Lyngdorf Audio TDAI-1120 – Owner’s manual
16
The Room Correction index is an estimate of how much the calibration filter will affect the sound
reproduction by evaluating the size of the filters as well as the frequencies adjusted. This index is not
absolute. For best results, rely on your own experience of the effects of the filter.
A low Room Correction filter on the focus position could indicate that you have positioned your speakers in
order to optimize the frequency response and not the timing.
Check “Tips for setting up speakers” on page 6 and complete a new RoomPerfect™ calibration.
4.2.3 Add focus position
If you would like to add an additional focus position, the chair next to the couch perhaps, it can be done here.
It is possible to have up to 8 different focus positions.
The saved calibration volume from the RoomPerfect™ guided setup is used as a default when adding extra
focus positions. The volume can be changed at any time between measurements to suit a particular
situation. This will not affect the quality of the measurement or the end result.
4.2.4 Add room measurement
It is possible to add more room measurements, which can increase Room Knowledge and thereby fine tune
all the room correction filters.
4.3 Volume
4.3.1. Default volume
The default volume setting controls the default volume at start-up.
4.3.2 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.
4.4 Voicings
Enables and disables voicings to enable quicker selection of your preferred equalization.
4.5 Display
4.5.1 Display brightness
Display brightness is used to control the brightness of the display.
4.5.2 Display timeout
If enabled, the main display will switch off after 10 seconds of inactivity.

Lyngdorf Audio TDAI-1120 – Owner’s manual

4.6 HDMI (Audio Input from TV)
HDMI (High-Definition Multimedia Interface) is a standard for transmission of video and audio from source to
playback device. The connection exchanges information as to available types of data against what the
playback devices will accept.
CEC (Consumer Electronics Control) is a HDMI feature designed to allow commands to be sent from one
product to another – as examples: allowing the player to turn on the television or to control the volume
setting of the TDAI-1120 by using the remote control of the TV.
In all setups the level of CEC implementation on the television sets the limitation to the possible integration,
and even if brand new, not all products will support CEC.
4.6.1 CEC enable
Enables and disables CEC (Consumer Electronics Control) over HDMI.
Note: As default, CEC is not active on HDMI to comply with regulations requiring a very
low standby power. Turning it on will raise standby power to 1.2W
4.6.2 CEC power control
Enables and disables CEC power handling.
This means when you turn on your TV or Blu-Ray player, the TDAI-1120 will automatically switch on from
standby as well. Furthermore, if you switch the HDMI input to a product which is in standby, it will be turned
on.
Note: Menu only appears if CEC is enabled.
4.6.3 CEC audio system
Enables and disables CEC audio system.
When enabled the TDAI-1120 tells the TV to disable its built-in speaker and to use the ones connected to the
TDAI-1120. Furthermore, this enables you to control the TDAI-1120 volume with the TV´s remote

Lyngdorf Audio TDAI-1120 – Owner’s manual
18
4.6.4 TV input
Select “HDMI ARC” if your TV supports ARC (Audio Return Channel) over its HDMI connection.
This means your TV can stream audio back through its HDMI connection to the TDAI-1120.
If your TV doesn´t support ARC, you can connect an analog or digital audio output from the TV to an audio
input on TDAI-1120. Select the used input in this menu so the TDAI-1120 will know from which input the
audio from the TV is coming. Remember to set up the TV to output to PCM on the digital output.
Note: If you don´t get any sound when the TV is connected to an alternative audio input, you may need to
turn off your TV and turn it back on again.
4.6.5 Output enable
Enables and disables HDMI audio output to the TV. This feature is only available if the digital output
connector is not in use.
When enabled, this feature will send the current digital audio signal though the HDMI cable to the TV.
Disable if you want the TDAI-1120 to send the current audio signal to the digital output connector on the
back.
5 Advanced settings
5.1 Auto off
If you don´t press any buttons or audio isn´t being played, this sets the idle time required for automatic shut-
down of the amplifier.
5.2 Remote control
Activate or deactivate the remote control. This function is useful if you are using a home automation system
and other remotes are using the same IR codes as the TDAI-1120 remote.
A home automation system is connected to the TDAI-1120 through the RS232 connector. Codes are
available for download from www.lyngdorf.com
5.3 ICC
Audio signals that exceed 0 dBFS (decibels relative to full scale) will be clipped when processed in the audio
chain and will result in more or less distortion. With ICC (Intersample Clipping Correction) the TDAI-1120 will
dynamically allow for extra headroom to avoid clipping.
ICC (Intersample Clipping Correction) can be set to auto or disabled.
The TDAI-1120 will continuously adjust the ICC in order to avoid clipping. Changing inputs or going into
standby mode will reset the ICC.

Lyngdorf Audio TDAI-1120 – Owner’s manual
19
If you switch to an active audio input and press info on the remote, you will see a “peak level” measurement.
This will show you if your signal has exceeded 0 dBFS.
5.4 Speaker setup guide
This starts the guided speaker setup and RoomPerfect™ setup. See “RoomPerfect” on page 10 for
instructions in how to calibrate your system.
Warning: This will erase ALL previously stored speaker settings and RoomPerfect™
measurements.
5.5 Second Speaker Setup
Here you have the option to store a second speaker setup. This will allow you to test another setup or to
have calibrated setups with and without a subwoofer, etc.
Enabling this will start the Guided Speaker Setup. When complete, the menu item Speaker Setup will be
available in the main menu, allowing you to switch between the two setups.
5.6 Outputs
The menus in outputs are where you will manually set up delays and crossover filters for your speaker
system. If the guided speaker setup has been completed the pre-made settings will be shown; these can be
optimized as well.
When building active speaker systems, it is recommended that you use the original crossover point(s) used
by the manufacturer. Due to the short wavelengths of the mid/high frequencies, it is essential that crossover
frequency, filter type, order, and delay are set correctly. Therefore, creating filters for speakers is an iterative
process that requires great knowledge and several critical listening sessions in order to achieve seamless
integration of the different speaker drivers.
Note: If you change the output setting, you have to do a new RoomPerfectTM calibration.
5.6.1 Delays
The available settings are:
Distance
If you are using a setup with speakers and/or subwoofers located at an identical distance to the listening
position, you don’t need to set a distance. If the distances are not identical, you need to enter it in order to
ensure that the sound from each loudspeaker reaches the listening position simultaneously.
To correctly measure the distance, please see Guided Speaker Setup.

Lyngdorf Audio TDAI-1120 – Owner’s manual
20
Amplifier delay
On analog and digital out, you can set an amplifier delay. If you have an active subwoofer or an additional
amplifier, there will be a natural electronic delay in these products.
Refer to the original manufacturer’s instructions to obtain the correct amplifier delay.
5.6.2 Main speaker output
The available settings are:
High pass removes the frequencies below the crossover frequency.
Low pass removes the frequencies above the crossover frequency.
Full range allows the signal to pass unfiltered.
Off mutes the output.
5.6.3 Analog output
The available settings are:
High pass removes the frequencies below the crossover frequency.
Low pass removes the frequencies above the crossover frequency.
Full range allows the signal to pass unfiltered.
Headphone disables RoomPerfect™, voicings are still available. Muting the TDAI-1120 will only mute the
speakers, not this output.
Tape Out disables RoomPerfect™, voicings and volume control.
Off mutes the output.
Volume
The volume can be set to regulated or full scale. Regulated means that the output level will follow the level of
the volume control. Full scale means there is a constant full scale output.
Warning: If full scale is selected, you will have full volume output, and this can overload
and damage speakers.
