Operating Voltage
The TDAI 2200 is available in two versions: one for 115V mains voltage and another for 230V mains volt-
age.
Check the label on the TDAI 2200 rear panel and verify you have the version with the proper voltage for
your area.
The 115V version requires a mains voltage of 110V-120V at 50-60Hz with a current rating of 8A.
The 230V version requires a mains voltage of 220V-240V at 50-60Hz with a current rating of 4A.
The mains voltage setting for your TDAI 2200 can be changed ONLY BY A QUALIFIED ENGINEER.
Connect the power input only to the AC source printed on the label. The warranty
will not cover any damage caused by connecting to the wrong type of AC mains.
The TDAI 2200 has three power modes:
1. OFF
No circuitry is powered.
2. STANDBY
The mains transformer and amplifier section are powered off - only the remote control input and the mi-
croprocessor is powered, so the unit can be powered up using the remote control ‘STANDBY’ button.
3. ON
All circuits active.
Unpacking the TDAI 2200
Carefully remove the unit and accessory kit from the carton, visually check for shipping damage.
Contact both the shipper and your Lyngdorf Audio representative immediately if the unit bears any sign
of damage from mishandeling. All Lyngdorf Audio equipment is carefully inspected before leaving our

Introduction to RoomPerfect™
Once the guided set-up has been successfully completed you have the option to listen to music through
two listening settings; Focus 1 and Global room correction filters. The RoomPerfect™ filters are stored
on the numerical buttons from 1 to 9 on the remote control. To change from one filter to the other you
simply press the numerical button corresponding to the desired filter, or toggle between them by press-
ing the Up/Down buttons on the remote or front panel.
Global is stored on numerical button 9 and the Focus 1 is stored on numerical button 1. Furthermore you
can add 7 more Focus/listening position (8 in all). The additional focus/listening positions can be stored on
numerical buttons from 2 to 8. To bypass the room correction filters, press numerical button 0.
Global Listening
The Global filter improves the sound quality across the whole room. When you are listening to music in
a room but are not sat in any particular listening position, the global filter gives the best result.
Focus Listening
The Focus filter improves the sound quality at a listening position by exploiting the 3-dimensional acous-
tic properties gained through the room measurements. This makes the Focus filter the best solution for
optimal sound quality at a specific listening position.
Voicing
The Voicing setting is an EQ filter that can be used to gently amplify or attenuate certain frequencies
according to your personal preferences and/or to compensate if a given recording sounds too ‘bright’ or
too ‘dark’. The standard voicing settings are:
•
Neutral, Music 1, Music 2, Open, Open Air, Relaxed, Soft.
The frequency curves of the different voicing settings can be viewed in the appendix. Neutral is a bypass
setting.
You can toggle between neutral and the available voicings by pressing the Left/Right buttons on the
remote or front panel.
When using RoomPerfect™ you will experience a much more precise and detailed sound reproduction
– which could also be described as more analytical. This means that it’s easy to distinguish poor quality
recordings.

Setting the Measurement Volume Level
The calibration volume is a recommended maximum volume. It is important that you always judge
whether the calibration volume is too loud. The calibration volume should not be so loud that it causes:
•
•
uncomfortably loud sounds that are inconvenient to you or your environment, or
damage to your loudspeakers.
When the message ‘Connect and place mic. in focus pos.’ appears, connect the microphone to the mi-
crophone input found on the back panel. Thereafter, place the microphone, using the microphone stand,
in an appropriate focus/listening position. This location should be at your main listening position, typically
more or less centered between the loudspeakers.
Make sure that the height and the orientation of the microphone corresponds to your typical listening
height and direction as illustrated and do not block the line of sight between the microphone and the
loudspeakers.
When the microphone has been correctly connected and placed in the focus position, you are ready to
set the calibration volume. The calibration signal is a combination of the high and low frequency measur-
ing signals and is only presented in your left loudspeaker. The measuring signals sound very artificial and
disharmonic due to the fact that they are composed of pure tones at different frequencies.
Press Enter to confirm and to commence the calibration process.
The test signal will start and shortly thereafter the DPA-1 will suggest an initial estimate of the desired
maximum calibration volume (in dB), displayed as ‘Desired vol. max XXdB – Retry/Save Current’
Please raise or lower the volume towards the desired maximum volume shown on the display but ensure
you avoid clipping, uncomfortably loud levels and damage to the loudspeakers. Continue choosing Retry
for a re-estimation of the desired maximum calibration volume, until an appropriate calibration volume
is reached. If you find the suggested calibration volume too loud simply turn down the volume to an ap-
propriate level and choose Save current.
When the message ‘Calibration ok. Press Enter to continue’ is displayed, the calibration volume has suc-
cessfully been set and saved.

16
Focus Measurement
When the calibration is OK, press Enter to start the measuring process and ‘Measuring Focus position
…’ will be displayed. Each measurement comprises four steps:
•
A low and a high frequency measuring signal first in the left and then in the right channel.
The length of each measurement depends on a combination of the measurement volume, set in the
calibration process, and the background noise in your local environment. Typical measuring times for the
low and high frequency measuring signals are 25 and 5 seconds, respectively.
You can exit a commenced measurement by clapping close to the microphone.
Do not sit in the listening position during focus measurements.
The measurement will stop prematurely if an error occurs during the measuring process. In this case,
an error message is displayed. Press Enter to continue and ‘Retry focus measurement – press Enter’ is
displayed.
If the error needs correcting this should be done at this point (see RoomPerfect™ troubleshooting),
thereafter press Enter to retry the measurement. The measurement procedure will start again.
A measurement has ended successfully when the last measuring signal stops and the display shows a
RoomKnowledge rating, as ‘RoomKnowledge XX% - Measurement ok’. Press Enter to continue.
Room Measurements
The number of room positions needed depends on the value of RoomKnowledge, if it is below 90% after
the third measurement the guide automatically includes extra room measurements until a RoomKnowl-
edge of 90% or more has been achieved.
The remaining measurements are to be placed in random positions in the room with random orienta-
tions of the microphone. Choosing these random or arbitrary positions and orientations is easy. All you
have to do is place the microphone at different positions in the room and with different orientations. It is
important to perform well spaced measurements to get a covering image of the acoustical properties in
the room, i.e. varying positions, heights and orientations of the microphone.
For an optimal room correction it is very important that the measurements are:
1. performed more than 1 meter (approx. 3 feet) away from the loudspeakers,
2. not performed behind the loudspeaker, and
3. that there is at least 50 cm/1.5 ft between each measurement.

When a random measuring position and microphone orientation has been chosen press Enter. The measur-
ing process will start and the display will show ‘Measuring room position 1’.
The measurement will stop prematurely if an error occurs during the measuring process. In this case, the
error message ‘Retry room measurement – press Enter’ is displayed. Press Enter to continue.
If it is an error that needs correcting, then correct the error (see ‘RoomPerfect™ trouble-shooting’ chapter)
and proceed with the room position measurement by pressing Enter. The measurement has ended success-
fully when the last measuring signal stops and the display shows ‘RoomKnowledge XX% - Measurement
ok’.
This process is repeated at least three times and until the RoomKnowledge reaches 90%.
Adding more Room Measurements
If you have performed successful measurements and RoomKnowledge has reached 90%, the message
‘Add more room meas.? Yes/No’ is displayed.
At this point, or any time later, you can decide whether the acquired room measurements are sufficient or
you wish to add further room measurements to learn more about the room’s acoustical information. Adding
more room measurements results in a higher RoomKnowledge, this in turn improves the room correction
filters.
•
Choose Yes to add more room measurements. The room measuring process is now continued as
described in the previous section.
•
Choose No when no additional measurements are required. The volume will now return to default
volume or lower, depending on the volume you have entered the guided set-up with.
The message ‘Save guided measurement - Yes/No’ will be displayed when exiting a successfully completed
guided set-up.
•
Choose Yes to save the results of the guided set-up and calculate the focus and the global room
correction filters.
•
Choose No if you wish to exit the guided set-up without calculating any room correction filters, without
saving the performed measurements and without setting the calibration volume.

Calculation of Focus 1 and Global Filters
When RoomPerfect™ calculates the filters the display shows the following, ‘Calculating filters - Please
wait’.
The filter calculation process can be expected to take anywhere between 5 seconds and a minute de-
pending on the specific task.
When RoomPerfect™ has calculated the room correction filters, they are automatically saved. The Focus
filter is saved as setting 1 and Global is saved as setting 9 out of the possible 9 filter settings.
You have now successfully completed a guided set-up and the RoomPerfect™ Advanced Menu is now
available.

Advanced Options
This section describes the options in the advanced menu, which is available after Guided Setup has been
completed. Here you can add new listening positions and room measurements, check the RoomKnowl-
edge of your current set-up, and check the RoomCorrection for the different filters.
Advanced options
Measure Focus Pos
Measure Room Pos
RoomKnowledge
RoomCorrection
Measure Focus Pos.
As mentioned, it is possible to add 7 different listening/focus positions.
Place the microphone correctly in the new listening position and the measurement process can com-
mence.
The saved calibration volume from the guided set-up is used as a default when adding extra focus/listen-
ing and room positions though, as mentioned, the volume can be changed at any time between meas-
urements to suit a particular situation.
After a successful measurement the message ‘RoomKnowledge XX% - Measurement ok’ is displayed.
Press Enter to continue.
The message ‘Save Focus measurement(s) – Yes/No’ will appear.
•
•
choose Yes to save the measurement or,
choose No to exit without saving the current measurement.
Choose between focus/listening position 2 - 8 and press Enter. If you wish to overwrite an existing Focus
filter (2 to 8 can be overwritten) or you are trying to save a new filter on an existing preset then ‘Focus
no.X exists! Overwrite? Yes/No’ will be displayed.
When the Focus number has been chosen, the volume turns down to default or lower and the new
Focus filter is calculated and saved.
Measure Room Pos.
It is always possible to add more room measurements, which can increase RoomKnowledge and there-
by fine tune all the room correction filters.
Press Enter to start a new room measurement.
Place the microphone in a random room position and the measurement can commence.
The saved calibration volume from the guided set-up is used as default when adding extra focus/listening
and room positions, though as mentioned, the volume can be changed at any time between measure-
ments to suit a particular measurement situation.
After a successful room measurement the RoomKnowledge is re-calculated and displayed as ‘Room-
Knowledge XX% - Measurement X ok’. Press Enter to continue.

‘Add more room meas.? Yes/No’ will show in the display:
•
•
choose Yes to add another room measurement or,
choose No to stop adding more room measurements. If No is chosen the volume is returned to
the default or lower.
‘Save room measurement(s)? Yes/No’ will hereafter be shown.
•
•
choose Yes to save the performed room measurement,
and No to exit without saving any of the performed measurements.
Adding one or more room measurements leads to a re-calculation of all filters (i.e. Global and all Focus
filters) due to the fact that more of room’s acoustic properties have been learned, something that affects
all filters.
RoomKnowledge
The RoomKnowledge index is a parameter that tells how much of the room’s acoustical properties have
been learned. A high RoomKnowledge ( 90%) means that most of the room’s acoustical properties have
been learned. The more room measurements you add, the higher the RoomKnowledge will become.
The more that the acoustical properties of the room are learned, the greater the accuracy of the room
correction.
RoomCorrection
The RoomCorrection index is a measure of how much processing is being employed in the room cor-
rection filters. To some extent the RoomCorrection index reflects how audible the correction is. How-
ever, the same amount of processing can sound very different due to placement in frequency of the
processing. For low values (below 10%) of the room correction index, only subtle correction is needed
to the original sound in the room. With high room correction index values more extensive processing is
employed.
The RoomCorrection index for a specific RoomPerfect™ filter can be viewed by pressing the numerical
button of the corresponding filter. This can only be done while in the RoomCorrection menu.

Input Sensitivity
The Sensitivity adjustment enables you to match levels from different sources as well as obtaining full
scale output on your amplifier. The Sensitivity can be adjusted +/-12dB in 0.1 dB steps.
Setting the Sensitivity too high will result in clipping/distortion. Therefore,
always use your ears when setting the Sensitivity

Comm Speed
Comm Address
The Communication Address setting identifies the TDAI 2200’s to the PC interface or other Lyngdorf
products. In master mode the amplifier setting is normally 1, and the addresses 2-99 can be used for
individual slave amplifiers, but nothing is restricted. The PC software must know the address of the TDAI
2200 in order to communicate with it.
Comm Speed
The Communication Speed setting is the RS232 Link interface speed. The default setting is 57600 baud.
With different PC’s and different lengths of cables the settings can be changed to 9600 or 115200 baud.
If a multi-amplifier set-up is installed with Master/Slave communication, a smaller delay can be observed
when using higher speeds.
Home Theater
If you are using a set-up with a Home Theatre Processor, where your Lyngdorf product is used to power
and calibrate the front left and right speakers, this feature will bypass the volume control. Connect your
HTP to the Analog Input 1 and activate the feature. Choosing Analog Input 1 will result in the amplifier
turning itself into a dedicated power amplifier with fixed and full gain.
(NOTE: do NOT test this feature with a CD signal running on the Analog input 1!)
When selecting other inputs the amplifier returns to the Default Volume
Master/Slave
As default a TDAI 2200 is set as a Slave. The Master setting should be used if you are using two TDAI
2200, e.g. for bi-amping or if using one to drive the main loudspeakers and one to drive the Lyngdorf
Audio cornerwoofer(s) or the subwoofer(s). When set as a Master the first TDAI will control the second
TDAI (the Slave), e.g. when adjusting the volume control and when switching on and off.

Line Out
The sub menus accessible in the ‘Line Out’ menu are:

Line Out Level
Line Out Control
The Line Out Control sets the output level to be Full Scale (fixed) or regulated.
Fixed means there’s a constant full scale output – most often used as ‘tape out’ or when using a
Lyngdorf Audio TDAI or SDAI as a ‘slave’ amplifier in a bi-amping set-up.
Regulated means that the output level will follow the level of the volume control. This setting is chosen
if you have, for instance, a power amplifier or an active subwoofer connected.
If Full Scale is selected you will constantly have full output – with huge potential for
overload and damage of power amplifier and/or loudspeakers if connected.
Line Out Level
This adjusts the overall output level in steps of - 0.1 db, it can be adjusted up to – 40 db in total.
Routing

Mono lowpass filter
A highpass and lowpass filter can be applied to the Main and Line outputs when you want to connect an
additional amplifier or subwoofer together with your main loudspeakers.
A Mono setting is also available for the Line output, this is used when connecting a single subwoofer to
just one Line output.
If no filter is selected the full frequency range will be directed to your main loudspeakers. If a filter is
selected the frequencies above or below the selecter crossover frequency will be directed through the
analog line-out and digital output terminals.
When a highpass or lowpass filter has been chosen, the Crossover Frequency and Filter Type menus are
enabled.

Crossover frequency
The crossover frequency can be selected anywhere between 40 – 9999Hz.
It is very difficult to give exact guidelines to setting crossover frequency, filter type and order since this
depends on the exact drivers and configurations. Therefore, the following recommendations should be
seen as a good starting point only.
In general, the recommended crossover frequency between (sub)woofers and main speakers is be-
tween 200 - 400 Hz.
By using a high crossover frequency, the rear wall quarter wavelength reflection is removed from the
main speakers.
If a Lyngdorf Audio corner woofer is used in a 2+2 set-up, a crossover frequency of 400 is recommended
due to the high bandwidth of the corner woofer.
For conventional active subwoofers with built in low pass filter the recommended crossover frequency
is the upper low-pass frequency of the subwoofer.
If at all possible, the low pass filter in the subwoofer should be bypassed. Due to the quarter wave
reflection from the rear wall corresponding to the depth of the subwoofer cabinet we recommend an
crossover point at approximately 200 Hz. You might experiment with turning the subwoofer so the driver
faces the wall in a distance of 5 to 10 cm. This will increase the bandwidth of the subwoofer.
However, due to the limited bandwidth (frequency response) of most conventional subwoofers you
might find it necessary to choose a lower crossover frequency.
When ‘building’ active speaker systems it is recommended to use the original crossover point(s) used
by the manufacturer. Due to the short wavelengths of the mid/high frequencies it is essential that both
crossover frequency, filter type and order as well as delay is set correctly. Therefore, creating filters for
active speakers is an iterative process that requires several critical listening sessions in order to achieve
seamless integration of the different speaker drivers.
Filter type
It is possible to choose from two different filter types in this menu.
LiRi: (Linkwitz Riley) 2, 4 or 8 order.
Butw: (Butterworth) 1, 2 or 4 order.
In a 2+2 set-up (main speakers + Lyngdorf Audio corner woofers) we recommend using a fourth order
Linkwitz Riley filter.
In set-ups using conventional active subwoofers – again due to limited bandwidth – we recommend us-
ing a second order butterworth filter.
In active speaker systems it is recommended starting with a fourth order Linkwitz Riley filter.

Delay
If you are using a set-up with two main loudspeakers located at an identical distance to the listening
position you don’t need to set a delay. However, if the distance isn’t identical and/or you are using a sub-
woofer, or a Lyngdorf Audio 2+2 system, you need to set a delay in order to ensure that the sound from
each loudspeaker reaches the listening position simultaneously. This must be done for main left (ML) and
right (MR) and as well as line left (LL) and right (LR).
To set the delay all you need do is to measure the distance from each loudspeaker to the listening posi-
tion and enter these values in the menu. The necessary delays are then automatically calculated and
applied to each channel.
1 centimeter = 0.3937 in
The fault message ‘Values for delay exceed limits’ is displayed when the difference
between the distance from the speakers closest to, and the speakers furthest from,
the listening position is too big. The biggest difference allowed is 340 cm / 134 in.
If the fault message appears, you can use the following solutions:
(Can be used individually or together to achieve a valid set-up with respect to the delay lengths):
•
Shorten the distances between your Main and Line channel loudspeakers resulting in a more
compact loudspeaker set-up.
•
Arrange your loudspeaker set-up and/or your listening position in a more symmetrical set-up.

Remote Control
Remote Control set-up makes it possible to activate or de-activate the remote control. This is useful in
set-ups with more than one TDAI 2200 amplifier in the room. The master amplifier then becomes the
only one receiving signals from the remote, processes them and controls the rest of the TDAI 2200’s
over the Lyngdorf RS232 link.
Software versions
The Software version menu is used to check the current software version of your TDAI2200 and the
RoomPerfect™ module as well as the RoomPerfect™ serial number.
Factory Reset
The Factory Reset setting is used to restore all settings, including RoomPerfect, in the TDAI 2200 to the
factory settings.
If you return to the factory settings all your personal settings will be erased.

RoomPerfect™ Troubleshooting
No microphone connected
The error message ‘No microphone connected’ is displayed when no microphone is connected to the
TDAI 2200.
Solution:
•
Connect the microphone on the right-hand side of the back panel.
No signal
1. The error message ‘Fault – No signal’ is displayed when the incoming signal is classified as
pure noise. This happens when the measuring signal is too low compared with the noise
from the local environment. This could be due to there being too much noise in your
measuring environment.
2. The above error message is also displayed when the loudspeakers are not connected and/or
Mute is activated.
Solution:
• Raise the measuring signal volume before continuing with the measurement.
• Connect your loudspeakers and/or de-activate Mute.
Signal clipping
1. The error message ‘Fault – Signal clipping’ is displayed when the incoming signal is
classified as too loud resulting in clipping (distortion).
2. A loud noise from the local environment that has corrupted the measurement results in this
error message.
Solution:
• Lower the measuring signal volume before continuing with the measurement.
• Repeat the measurement with no changes; however refrain from making excessive noise
when measuring.
Low signal
The error message ‘Fault – Low signal’ is displayed when the measurement has taken more than 5
minutes for the low frequency signal or 2 minutes for the high frequency signal. This happens most
often when using a low measuring signal compared to the background noise of your environment,
something that results in prolonged measuring times.
Solution:
• Raise the measuring signal volume before continuing with the measurement, or reduce the
noisy elements in your environment.
