Tips for setting up speakers
Tip: With hard floors, you can reduce reflections from the floor by positioning a carpet between you and
the speakers. With hard surface walls, you can use a painting, a book shelf, or other furnishings.
Find the position of the diffusers by having someone hold a mirror against the wall opposite the speaker.
When you can see the speaker in the mirror from the listening position, you have found the optimal
position for the diffuser.
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.

12 13
Speaker placement
For an optimal listening experience, we
recommend you place your speakers against
the back wall. This will ensure the back wall
audio 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.

14 15
Connecting the subwoofer
In a traditional single subwoofer setup, connect the subwoofer to the left analog out on the TDAI-2170.
For a stereo subwoofer setup, or if you have a subwoofer which has stereo input, use both left and right
analog out.
Warning: Do not connect the TDAI-2170 to a subwoofer with speaker terminal inputs if they are
grounded. The TDAI-2170 +/+ speaker output
terminals must never touch each other, likewise the
-/- speaker output terminals. ANALOG

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.
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 maximum volume.

Measuring distances
When measuring the distance to your main speakers, measure
from the focus position to the front of the speakers.
When measuring the distance to a subwoofer, measure from
the focus position to the back corner of the subwoofer.

RoomPerfect™
RoomPerfect™ is designed to analyze and correct for the negative effects that the listening room has
on the speaker sound.
Global listening 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 listening 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.
Voicings A voicing is an equalizer filter that can be activated to amplify or attenuate certain frequencies
according to your personal preferences. This equalization is an addition to the RoomPerfect™
corrections. The equalizer settings of a given voicing can be seen on the display of the amplifier.

22 23
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 back panel 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.
Press enter and a test signal will start from the left speaker. The TDAI-2170 will give an estimated
optimal volume for calibrating the system or will accept the current volume. Adjust the volume if
required 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 end result.

24 25
Measuring the focus position
When the calibration volume has been set, RoomPerfect™ will send a range of 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 end result.
See RoomPerfect™ troubleshooting if the measurement will stop 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 will stop
prematurely.
Keep taking measurements until RoomKnowledge reaches 90%.

26 27
These are the rules of thumb when measuring the room:
• the microphone should be in random and varying positions, heights, and orientations.
Point it up/down/sideways, the more random positions the better.
• the measurements should cover the entire room, not only your listening area.
• do not take measurements behind plants, furniture, ext.

• the microphone should not be 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.

Room measurements above 90% RoomKnowledge
When RoomKnowledge has reached 90%, you can decide to add room measurements or can elect to do it
at a later time. We recommend taking a couple of measurements within 50cm/.5ft of the walls and ceiling
when above 90% RoomKnowledge
To fully optimize RoomPerfect™’s 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 TDAI-2170 will calculate the focus and global filters
automatically.

4.1 Inputs
In general, the settings in these sub-menus are specifically for the current active input.
Note: We recommend setting the output of a CD-player to 44.1 kHz. The TDAI-2170 will then get the
original signal from the disc which allows for ICC (Intersamle Clipping Correction) to function.

34 35
4.1.1 Active inputs
Enables and disables individual inputs so you do not have to scroll through unused inputs.
Note: To store the changes made scroll to the right in the menu and press the “Enter to store” text.
4.1.2 Input name
Changes the name of the selected input.
Note: To remove all text after the blinking marker, press and hold the “Down” button on the remote.
4.1.3 Sensitivity
Enables you to match input levels from different sources. Can be adjusted up to +24dB.
4.1.4 Default voicing
Selects a default voicing for the input which is active when in this menu. If you always want extra bass
on your gaming console audio, set that voicing here.
4.1.5 Home theater
Turns the amplifier into a dedicated power amplifier for the input which is active when in this menu. This
feature bypasses the volume control.
Warning: Do not test this setting with a CD player or similar unregulated signal!
This feature might be selected if you are using the TDAI-2170 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 Guided setup
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 RoomKnowledge
and RoomCorrection index.
The RoomKnowledge index is an estimate of how much of the room’s acoustical properties have been
learned from the room measurements. The higher the RoomKnowledge index, the greater the accuracy
of the calibration.
The RoomCorrection 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 RoomCorrection 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 our guide to speaker positioning and complete a new RoomPerfect™ calibration.
4.2.3 Add focus position
If you would like to add an aditional 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 RoomKnowledge and thereby fine
tune all the room correction filters.

38 39
4.3 Volume
4.3.1. Default volume
The default volume setting controls the default volume at startup.
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 prefered 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.
4.6 HDMI
Note: To comply with regualtions of having a very low standby power, as default CEC is not active on
HDMI. Turning it on will raise standby power to maximum 1.2W.
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 their remote controls (for example, controlling the TDAI-2170 audio 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, including TV or other
sources, support CEC.
