Getting Started
Thank you for purchasing the Rotel RSS-900 Speaker Selector.
When used in a high-quality music audio system, it will provide
years of musical enjoyment.
The RSS-900 answers the dilemma faced by many audiophiles
who want the flexibility and convenience of a multi-speaker, multiroom system without having to sacrifice sound quality. The
RSS-900 provides a switchable set of “Direct” speaker connections to ensure the speakers in the primary listening location receive an unaltered signal. In addition five other switchable sets of
connections are provided. These outputs have impedance compensation that allows any combination of speakers, or all the
speakers, to be switched on. These outputs also have inductor
coils connected to them to counteract the effects of excess capacitance that can result from long, multiple runs of speaker
wires. This additional circuitry ensures that your amplifier will
produce the best possible sound, regardless of which speakers
are switched on.
The RSS-900 is straightforward in its installation and operation. If
you have experience with other stereo systems, you shouldn’t find
anything perplexing. Simply connect the associated components
and enjoy.

Associated Components
The RSS-900 is designed for use with amplifiers that can produce
as much as 200 watts per channel. (See the information in the following section regarding ventilation.) The amplifier should be capable of handling 4 ohm impedance loads.
NOTE: If speakers that have a minimum impedance of less than 4
ohms are connected to the RSS-900 the impedance the amplifiers
receives may be less than 4 ohms. Check the instruction manual
for your speakers for this information. If you are unsure about
whether or not a certain combination of speakers can safely be
used with the RSS-900 and your amplifier consult your authorized
Rotel dealer.
Placement
Place the RSS-900 on a firm flat surface where it will be free from
excessive dust, heat or cold, moisture or high humidity, or exposure to direct sunlight. Do not allow any foreign objects to fall into
the ventilation holes of the RSS-900.
Like many audio components that handle high-level signals, the
RSS-900 produces some heat during normal operation. Do not
place anything on top of the RSS-900 or allow the vent holes in the
top of the cabinet to be blocked. There should be at least 3”
(75mm) of room above the RSS-900 to allow for heat dissipation.

Connection
Note: Turn off the power to all the components in the system before you make any signal connections.
Polarity/Phasing and Proper Channel Connection
The polarity — the positive/negative orientation — for every connection between the amplifier and the RSS-900, and between the
RSS-900 and the speakers, must be consistent so all the speakers
will be in phase. If the polarity of one connection is mistakenly reversed, bass output will be very weak and stereo imaging degraded. All wire is marked so you can identify the two conductors.
There may be ribs or a stripe on the insulation of one conductor.
The wire may have clear insulation with different color conductors (copper and silver). There may be polarity indications printed
on the insulation. Identify the positive and negative conductors
and be consistent with every connection.
Note: All speaker wire consists of many small strands of wire.
When making connections to the terminals of the amplifier, the
RSS-900, or the speakers, twist these strands into a tight bundle
and secure all the wires in the terminal. There must not be any
loose strands of wire from one terminal that could touch the other.
This will cause a short circuit.
Cables
Because as many as 6 pairs of speakers may be connected to the
outputs of the RSS-900, the wires from the amplifier output to
RSS-900 input should be heavy gauge (12 AWG) speaker wire.
Slightly lighter gauge wire may be used to connect the RSS-900 to
the speakers. High quality, high performance wire will frequently
improve the sound of a system. Consult your authorized Rotel
dealer for advice about the best wires to use with your system.
It is also very important to be sure that the left and right channels
do not get reversed. Work carefully and be sure that the proper
channels are connected at every amplifier, RSS-900 and speaker
connection point.
Input From Amplifier
(See the connection diagram Figure 2)
Use heavy duty speaker wires to connect the output of the amplifier to the input of the RSS-900 as shown.
Direct Speaker Output Connection
Connect the speakers in your primary listening location to the output terminals labeled “Direct”. These outputs do not have the impedance matching and capacitance control components that the
other outputs (1-5) have. This provides you with the convenience
of being able to turn the main speakers in your system on and off,
while ensuring that the signal to them is not affected by extra circuitry.
Speaker Output Connections 1 – 5
Connect the secondary speakers in your system to the outputs labeled 1 through 5. These outputs have impedance matching and
capacitance control components that allow the amplifier to safely
drive any combination of speakers.

Troubleshooting
Most difficulties in audio systems are the result of incorrect connections, or improper control settings. The RSS-900 is a passive
device with no power supply or components that are likely to fail.
If you encounter problems, it is probably the result of another
component in the system. If the problem does involve the RSS-900
it is probably a matter of improper connections.
No Sound
If one or both channels is not producing sound, check to see if
other speaker outputs are functioning properly. If the problem is
isolated to one set of speakers it is probably the result of improper
connections to the RSS-900 or the speakers.
If all the speaker sets in the system are experiencing the same
problem check another signal source. If neither channel is producing sound check the tape monitor switches on the preamplifier
(or integrated amplifier, or receiver) to be sure they are properly
set. If the problem persists check the connections between the
preamp and power amp (if appropriate) and the connections between the speaker outputs and the RSS-900 inputs. Be sure there
are no loose strands of wire causing a short circuit between the
connection terminals at either the amplifier outputs or the RSS900 inputs.
Distorted Sound
There is almost nothing that involves the RSS-900 that could produce distorted sound. Such problems are almost certainly the result of problems elsewhere in the system. In rare instances a
loose strand of speaker wire that is barely touching the other wire
or terminal can cause an intermittent crackling noise. This is easy
to check and eliminate as a possible source of the problem.
