RoomPerfect™
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.
It is possible to add multiple focus positions. This must be done after RoomPerfect™ has
been set up completely.
Edit distance
Be sure to select the unit of measure, then enter the distances to the speakers and woofers.
How to measure distances to speakers and woofers
The best results are obtained by using a laser-equipped measuring device. Before starting, place the
RoomPerfect™ microphone at listening height in the main listening position. For each channel, measure the
straight-line distance through the air from the tip of the RoomPerfect™ microphone to the center of the
tweeter unit in the loudspeaker in question. Do not measure distances at floor level, as these measurements
will not give acoustically accurate results.
When measuring distances to in-room boundary woofers:
• If the stack of woofers is taller than the listening position, measure the distance from the listening
position to the back edge of the middle of the stack of woofers.
• If the woofers are lower than the listening position, measure the distance from the listening
position to the back edge of the top woofer.
When measuring distances to in-wall boundary woofers:
• If the stack of woofers is taller than the listening position, measure the distance from the listening
position to the dust cap of the middle of the stack of woofers.
• If the woofers are lower than the listening position, measure the distance from the listening
position to the top dust cap of the top woofer.
If in doubt, contact your Steinway Lyngdorf representative for guidance.

Steinway & Sons Head Unit Processor – Installation Manual, version 1.0
15
Do not measure distances at floor level, as these measurements will not give acoustically
accurate results.
How to Set Up RoomPerfect™
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 Steinway Lyngdorf
representative before performing the system calibration.
Volume Setting
The system guides you through the selection of a proper calibration volume level. Follow the instructions on
the display to find the optimal volume setting for doing the calibration.
You can choose to use a volume setting other than the one requested by the system by choosing Use Current.
The calibration will not be inferior in quality, but the time required for an exact measurement will be longer. If
the volume setting is too high, the system will display Error – Clipping. Reduce the volume and try again.
RoomPerfect™ Preparations
• Place the RoomPerfectTM 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 microphone terminal on the rear panel of your processor.
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 system 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

Steinway & Sons Head Unit Processor – Installation Manual, version 1.0
16
longer calibration time or a measurement time-out. A low volume and long measurement will not affect the
quality of the end result.
The display reads 0 to 99.9 as volume level, where 88 refers to full gain (0 dB)
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 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%.
These are the rules of thumb when measuring the room:

Steinway & Sons Head Unit Processor – Installation Manual, version 1.0
17
• 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, 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.
Room Measurements Above 90% RoomKnowledge

Steinway & Sons Head Unit Processor – Installation Manual, version 1.0
18
When RoomKnowledge has reached 90%, you can decide to add room measurements or 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 system will calculate the focus and global filters automatically.
Audio Setup
Audio Processing
This menu allows you to manage the audio processing presets for DTS, NeoX, AURO, and Dolby.
Voicing Setup
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.
Voicings can be edited, deleted, added or loaded in the Head Unit Processor.
Editing and adding voicings

Steinway & Sons Head Unit Processor – Installation Manual, version 1.0
19
In the intuitive GUI for the voicing tool, you can edit or add a voicing by combining up to eight filter sections.
For each section, you can choose between parametric or high and low shelves as well as high and low-pass
filters. Once the filter type is selected, you can insert a center frequency, Q, and gain. Then the filter, including
the final voicing, is shown as a graph so that you can immediately see the result.
We recommend you create voicings using the web interface, but they can be created using the remote
control.
Zone B
Setup
Here you can adjust the Zone B volume and default settings.
The Zone B output is a stereo downmix of the main zone audio – intended for use as an
input in adjacent space.
