SYSTEM INSTALLATION
Rack Installation
The SP-1 Stereo Processor is, depending on the order, shipped with foot rails for free- standing placement or
rack mounts. To install the rack mounts, turn the SP-1 Stereo Processor upside down and place it on a stable,
even surface. Take care to place it on a soft surface to avoid scratches. Using a TORX 10 screwdriver, fasten the
rack brackets in the designated holes.
The SP-1 should be installed with at least one inch of free space on all sides, and it should be placed in an
environment free of excessive heat. When placed in a rack system, the SP-1 should be placed at the bottom of
the rack, with the Steinway Lyngdorf amplifiers above it. This allows for proper dissipation of the heat
generated by the amplifiers without adverse effects on the SP-1.
CABLE CONNECTIONS
Power Cable Connections
Use only the power cables included with the product. Using other cable and/or plug types will void the
warranty and may cause damage to the system.
Interconnect Cable Connections
This Steinway Link cable carries both the digital audio signal as well as the control signals.
If using other cables for cabling between the processor and amplifiers, please use cables with standard RJ45 to
RJ45 B connectors. All RJ45 connectors should be shielded. For cable lengths less than 1 meter, use
CAT5E/shielded or CAT6 cable. For cable lengths in excess of 1 meter, use double- shielded CAT5E cables. Poor
quality cables and plugs may violate safety and EMC regulations, as well as cause significant noise and
interference. Only use cables and connectors approved by Steinway Lyngdorf.
Please refer to the wiring diagram supplied by Steinway Lyngdorf to determine which cables you need.
Using the USB Audio Input
To play sound from a computer to the SP-1, connect your computer to the USB-B input using a USB cable.
Select “USB” as input on the SP-1, and start playing on your computer. If the audio signal is part of a video or
movie, synchronizing might be necessary. Video delays have to be set in the computer; audio delays can be set
in the SP-1’s input settings (“Lipsync delay”).
SOFTWARE UPDATE
Updating the SP-1
• Save the new software on a USB stick.
• Switch off the SP-1 using the mains switch on the back.
• Insert the USB stick in the appropriate connector on the back of the SP-1.
• Press and hold the standby button on the front of the SP-1.
• Switch on the SP-1 using the mains switch on the back, while holding the standby button.
• Wait until the SP-1 has loaded the software, updated the software, and powered off to standby. Do not
remove the USB stick before the SP-1 has powered off, as this will cause the software in the SP-1 to be
corrupted.

SETTING UP ROOMPERFECTTM
Introduction
RoomPerfectTM is designed to analyze and correct for the negative effects that the listening room has on the
speaker sound.
To correct for the way the room acoustics affect sound reproduction, RoomPerfectTM must map the acoustical
properties of your listening room. For this purpose, a microphone with stand is included in the Installer Kit. The
Guided Setup menu allows you to initiate a new set of RoomPerfectTM room measurements.
After the RoomPerfectTM calibration, further settings can customize the sound:
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. You can have up to eight Focus positions for
the room.
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.
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 RoomPerfectTM corrections.
RoomPerfectTM Preparations
• Place the RoomPerfectTM calibration microphone on the stand. Be sure to fasten all handles and clamps
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 the SP-1.
WARNING: The 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.
Placing the Microphone in the Focus Position
When you are prompted to place the microphone in the focus position, 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.

Steinway & Sons SP-1 – Installation Manual
16
Setting the Volume Level
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.
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.
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 – Signal Clipping.” Reduce the volume
and try again.
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.
Measuring the Focus Position
When the calibration volume has been set, RoomPerfectTM 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 RoomPerfectTM troubleshooting if the measurement stops prematurely, and then retry the measurement.

Steinway & Sons SP-1 – Installation Manual
17
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 RoomPerfectTM troubleshooting if the measurement stops prematurely.
Keep taking measurements until Room Knowledge reaches 90%.
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, 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.

Steinway & Sons SP-1 – Installation Manual
18
Room Measurements Above 90% Room Knowledge
When Room Knowledge has reached 90%, you can decide to add room measurements or do it at a later time.
To fully optimize RoomPerfectTM’s understanding of the room’s acoustical properties, we recommend you
keep doing measurements until the Room Knowledge is above 95%. The higher the Room Knowledge, 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.
RoomPerfectTM Status.
This menu shows how much the correction system knows about the room, and how much correction has been
employed. Room Knowledge is an index showing how many of the acoustical properties in a room have been
mapped. The higher degree of knowledge in the system, the greater the accuracy of the room correction
filters. The Room Correction index is a measure of how much processing is being employed in the room
correction filters. To some extent, the Room Correction index reflects how audible the correction is. 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.
Add Focus Position/Add Room Position.
You can add up to seven more Focus positions for the room, repeating the Focus 1 measurement procedure.
You can also add more room measurements to approach 100% Room Knowledge.

RoomPerfectTM Troubleshooting
Error: Noise on signal!
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 the measurement.
Error: Microphone not found!
No microphone is connected to the SP-1 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.
Error: Signal clipping!
There are two possible causes of this error. 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.
Error: Signal too low!
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 from the environment before
continuing with the measurement.
Error: 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.
Check the sound volume.
Check all cable connections.
Check the measuring signal volume.
If none of these measures solve the error, request a replacement microphone from Steinway Lyngdorf.

SPEAKER ROUTING
Overview: Assign ID Codes to the Steinway Lyngdorf Amplifier(s)
The DIP switchboard on the back of the amplifier must be encoded in order to make it possible for the SP-1
Stereo Processor to identify the amplifier. Each unit must have a sequential ID in the network.
This is how amplifiers are setup correctly (example: 1 - 6 amplifiers):
Overview: Link Termination or Daisy-Chaining
DIP 8 must be adjusted for either termination or transmission. Switch DIP 8 to lower position if you want to
connect more amplifiers to the Steinway Link output. Switch to upper ON position if there are no further
amplifiers in the chain.
SP-1 Speaker Setups and Wiring Rules
Wiring of the amplifiers and speakers connected to an SP-1 is determined by a set of rules, depending on how
many channels are used for the main speakers and which types of amplifiers are used.
There are a generic set of rules for 1-way speakers and one for 2-way speakers. Then there are specific rules
for Model B, Model C and Model D.
There is also a special “Parallel Mode” which can be enabled in the settings used for setups where amplifiers
for left and right are physically separated, this is described in its own chapter later. For all standard setups,
rules are as follows.
