9BSST FIVE CHANNEL POWER AMPLIFIER
Introduction
Thank you for choosing the 9BSST Five Channel Power Amplifier.
Bryston welcomes any suggestions you may have, or comments regarding the operation of your amplifier. We consider
you, our customer, to be Bryston’s most important resource, and your opinion is very much appreciated.
Description
The 9BSST is a modular design 5 x 120 Watts per channel audio power amplifier. Each channel selects a balanced or
single ended input. Each channel selects a gain of 29dB(1v), 23dB(2v) or 17dB(4v). Each channel input may be operated inverted or non-inverted operation (0 or -180 degrees). The power up of the 9BSST may be controlled by a remote
control voltage. The 9BSST includes ‘soft start’ power control circuitry to eliminate high inrush currents when A/C power
is applied.
Warranty ( see back page for details )
Shipping Box & Packing Material
Please keep the original shipping box and all packing material. This will ensure the amplifier is protected in future transport. In the unlikely event you have a problem and must return it for service you must use the proper packing material. Ship the
amplifier only in the original packing material, as the unit is not insurable by carriers otherwise.
Installation ( see rack mounting section if applicable )
Ventilation. The most important installation consideration is ventilation. The 9BSST is a convection-cooled amplifier.
Unrestricted air-flow across its heat sinks is a must. For this reason do not install anything directly above it. Allow 3.5”
(2u) to 5” (3u) inches of space above and to the sides of this amplifier. Do not install directly above other heat generating
equipment. Should your installation conditions be constricted, then additional forced air-cooling may be necessary. Bryston
can provide an optional fan package if required. Any 9BSST channels thermally shutting down during operation indicates
insufficient cooling, and a remedy must be found for cooling the amplifier. Provide a minimum 6” space to the rear of the
9BSST for ventilation and dressing cables to and from the amplifier.
Never operate the 9BSST in a vertical position.
Wiring the 9BSST ( also see rear panel description )
Speaker wires should be as short as practical. Use quality wire, and if runs are more than 3 meters use at least 12 gauge
wire. The speaker binding posts will accept wire up to 3 gauge in size. Bryston can custom build cables for your application.
A/C power Before plugging in the power cord be sure your 9BSST is specified for the correct A/C voltage for your locality. The voltage
is listed to the right of the power input connector. The circuit feeding the 9BSST should be sufficient so as not to cause the
circuit breaker to trip. Note: the 9BSST when operated with all channels at maximum power into 4 ohm loads, can consume
all the available power in a normal household circuit, therefore a dedicated electrical circuit may be necessary with this
situation. Never lift the safety ground to the amplifier or remove the ground pin from the plug.
Power line conditioners will not improve the 9BSST performance, in fact most of the time they restrict the flow of current in the power line to the amplifier, reducing performance at high output levels.

9BSST FIVE CHANNEL POWER AMPLIFIER
Rear Panel Input / Output Connections
1. Input Select Switch.
Each 9BSST channel gives the user the option of switching between
either balanced input or single ended input.
2. Balanced Input connector. ( Imp. 20k )
This input connector accepts standard ‘XLR’ or 1/4” TRS .
Use quality, 100% shielded cables with gold plated connectors.
‘XLR’ type
‘TRS’ type
‘RCA’ type
3. Single Ended Input. ( Un-balanced input ) ( Imp. 50k )
This input connector accepts standard ‘RCA’ or ‘Phono’ connectors.
Use quality, 100% shielded cables with gold plated connectors.
Balanced input Vs Single ended input:
Fig 1
The balanced input requires a balanced pre-amp source. Balanced
systems provide noise protection from external electrical interference,
so cable length can be very long (50m or longer ).
The single ended or unbalanced input is provided for pre-amps without balanced output. Single-ended cables should be
kept to 20’ (7m) or less. In general never use longer cables than necessary, never coil excess cable length, and run signal wires away from AC power or speaker cables.
4. Polarity Switch ( 0 or -180 degrees)
Each 9BSST channel gives the user the option of inverting the polarity of the input signal -180 degrees.
Polarity inversion is application specific. The normal operating position is 0 degrees.
5. Input Sensitivity (Gain) Switch.
The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference.
The 1v setting is used when the source is single-ended, or from a transformer coupled balanced source.
This is the home theatre setting for single ended or un-balanced operation.
The 1v setting provides the most amplifier gain - 29 dB. (1v in = 100w @ 8 ohms.) (noise -110 dB)
A signal level of 1.1v at the input is required to deliver 120W into 8 ohms (rated output).
The 2v setting is used when the sources output is actively Balanced.
This is the home theatre setting for balanced operation Or use this setting with any systems where
the volume control rotation is limited to the bottom half of the control or less. The 2v setting provides an amplifier gain - 23 dB. ( 2v in = 100w @ 8 ohms.) ( noise -112 dB )
A signal level of 2.2v at the input is required to deliver 120W into 8 ohms (rated output).
The 4v setting is used when the source pre-amp has a high output level, or in ultra sensitive systems where
the volume control rotation range is still limited when using the 2v setting.
Some pre-amps may be unable to deliver enough level to use this setting.
The 4v setting provides an amplifier gain - 17 dB. ( 4v in = 100w @ 8 ohms.) ( noise -115 dB )
A signal level of 4.4v at the input is required to deliver 120W into 8 ohms (rated output).
The noise is referenced in dB below rated output of 120 watts. Different input configurations result in slightly different
noise readings. The above noise ratings represent minimum readings, actual readings may be better.

9BSST FIVE CHANNEL POWER AMPLIFIER
6. Output binding posts
The RED binding post is connected to the amplifier output. Connect to this post the (+) terminal on the loudspeaker.
The BLACK binding post is connected to signal ground. Connect to this post the (-) terminal on the loudspeaker.
When the polarity switch is set for 0 degrees (normal operation ) the output at the RED binding post is in phase with the
input signal.
When the polarity switch is set for 180 degrees (inverted operation) the the output at the RED binding post is 180 degrees
out of phase with the input signal.
The Output binding posts provide three different interconnect options. Combinations may be used when bi-wiring. See figure 2 below. Cables should be kept as short as practical and should never be terminated with connectors that may become
confused for AC power connectors. Cables should be dressed away from input and power cables.
1. Banana plugs offer a quick disconnect option. Before inserting a banana plug into the binding post be sure to tighten the
post nut to avoid rattling and to provide full insertion of the banana plug. Gold plated locking banana plugs are available
from Bryston.
2. Spade lugs provide high contact area and secure fastening. Lugs should be gold plated. See diagram for details.
Post diameter is 5/16’ ( 8mm ),lug width 5/8” (16 mm). Gold plated spade lugs are available from Bryston.
3. Stripped bare wire up to 3 gauge can be inserted through the hole in the binding post and held in place by tightening the
post knob. Additional tightening pressure can be achieved using the wrench provided in the slots of the knob. Do not over
tighten or the binding post may become damaged. Note that copper wire is malleable and may require further tightening
after the initial installation.

Front Panel
1. 'SST POWER' switch
The front panel label 'ST POWER', is a touch sensitive membrane switch used to apply or remove A/C line power to the
9BSST circuitry. Push firmly the center of the switch until the power-up sequence begins. Push again and the 9BSST will
power-down. ( Note: the rear circuit breaker must be on for the 9BSST to power-up)
2. LED Indicators
Each 9BSST channel has a LED
indicator to monitor the following conditions:
Unlit -
indicates channel has no power.
Red - indicates channel is muted (power-up-down sequence)
Green - indicates channel operation is normal.
Flashing Red - indicates channel clipping.
Orange -
indicates channel thermal shutdown.
Power up sequence
After pushing the 'SST POWER' switch, each channel led will turn from unlit to red (mute). When the power supplies
have stabilized the channel will come out of mute and the led will change to green (normal operation).
Unlit led ( No power )
The 9BSST channel led when unlit indicates no A/C mains power is present at the channel. If all channel led indicators
are unlit the 9BSST probably needs only to be powered on. A single led not lighting possibly indicates blown channel
fuses.
When checking fuses switch off the circuit breaker on the rear panel, or unplug the power cord. Use only the specified
quick-acting 4 amp 250V 5mm x 20mm fuses. See page 6 for the fuse locations.
Clipping ( flashing red )
Clipping occurs when the channel output level no longer can follow the level increase at the input (Over driven input condition). When a 9BSST channel is driven into clipping the channel led will change from green to red then back to green
when the level is reduced ( Flashing Red ). Momentary clipping can be tolerated, however it indicates that maximum undistorted power has been surpassed and potential speaker damage may result if overload conditions persist. Any amplifier that is constantly operated into clipping indicates a more powerful amplifier is needed for that application.
Thermal Shutdown ( orange )
The 9BSST channel has thermal shutdown circuitry to prevent damage due to overheating.
Should thermal shutdown occur, the channel will mute, and the channel led will turn orange indicating this condition.
When the channel has cooled to a safe operating condition the channel will return to normal operation.
Persistent Thermal shutdown indicates steps need to be taken to increase airflow across the channel or channels heat
sink. ( Also see installation section on ventilation ).

9BSST FIVE CHANNEL POWER AMPLIFIER
REAR POWER ENTRY PANEL
Power Control Panel
1. Master circuit - breaker.
The 9BSST uses a magnetic-trip circuit breaker (1) to protect the amplifier.
This switch should be ‘OFF’ when installing the 9BSST. When switched ‘OFF’
all A/C power is removed from the amplifier, including standby power.
The circuit breaker is not the day to day power switch and should be switched and left
‘ON’ after the installation is complete.Use the ‘ST POWER” switch or an external control
voltage to Power-up or Power-down the amplifier.
Should the breaker trip, lower or remove the amplifier input signals. Switch the breaker
to the ‘ON’ position. Then power the unit up normally. The circuit breaker must be ‘ON’
at all times for the 9BSST to operate.
2. AC power input.
This is a high current plug for the power cord receptacle. Check that the voltage rating
at the right of the connector conforms with your locality. With the circuit breaker ‘OFF’
insert the power cord into the 9BSST, then plug the other
end to an approprate A/C power outlet.
3. Power-Up ( Local / Auto switch. )
A. In “Local” position either the front panel ‘ST POWER” switch or an
external voltage controls the power-up of the 9BSST.
B. “Auto” is used when the 9BSST is powered from a switched power outlet.
The ‘ST POWER’ switch and / or control voltage will function normally after the initial power up.
4. External control voltage power up ( Local / external switch.)
A. To power-up the 9BSST using an external control voltage,
Supply a 4v to 12v A/C or DC control voltage to the ‘IN’ terminals of connector ( 5 ).
Use paired wire of 22 gauge to 18 gauge sufficient in length between the source device and the 9BSST. (see ‘W’ )
Select switch (4) to “External”. The amplifier will now power-up only when the control voltage is present (on).
Immediately following power up, the control voltage will appear at the ’OUT’ terminals of connector (5) for the control
of other equipment.The Removal of the control voltage ( 0v) causes the 9BSST to turn ‘off’ and the control voltage at
the ‘OUT’ terminals is interrupted.
B. In the“Local” setting of switch (4) the 9BSST will ignore the control voltage, and power up only by using the
front panel ‘ST POWER’ switch, or as in section 3 above. If a control voltage is present at the ‘IN’ terminals it
will still be available at the ‘OUT’ terminals after the power-up sequence.

When bridging “PRO” channels which are
equipped with level controls, it is
imperative that the level controls on BOTH
channels being bridged be set to their
maximum clock-wise positions (0 dB).
The same signal is fed into both amplifier channel inputs via a “Y” adaptor cable. Note that the POLARITY of
one channel is the inverse of the other. THIS IS ESSENTIAL for the amplifier to operate in bridged mode.
Failure to INVERT one of the channels relative to the other will result in zero output. It does not matter
which channel is set to zero degrees and which one is set to 180 degrees, however, as long as they are
different.
When bridging two channels together the resultant output will be increased by 6 dB relative to the output
of a single channel. To keep the gain of a bridged channel the same as that of a single channel, the
SENSITIVITY switch should be set to a higher voltage setting. For example, if a single channel is set to “1V”
sensitivity, then both the bridged channels would be set to “2V”. Likewise, if a single channel were set to a
sensitivity of “2V”, then the bridged channels would be set to “4V”.

Bryston can supply Bridging Kits
consisting of a “Y” adaptor cable
and a ground strap cable. The “Y”
adaptor cable can be equipped with
either RCA (Phono) connectors
(Part # 150901) for single-ended
applications, or with XLR
connectors (Part #150902) for
balanced applications. The ground
strap cable is equipped with gold
plated spade lug connectors on
either end. Bryston Bridging Kits
are designed for use with adjacent
channels.
BRIDGING KITS
WARNING! RISK OF HAZARDOUS ENERGY. MAKE PROPER SPEAKER CONNECTIONS.
SEE OPERATING MANUAL BEFORE USING.
While any two channels can be bridged, we recommend that adjacent channels
be used (as shown) to facilitate the external wiring between the channels.
Note that only the POSITIVE (+) terminals on the 6B power amplifier modules
are connected to the speaker.
A ground wire (16g or heavier wire
recommended) must be connected between the two BLACK output terminals
on the 6B amplifier channels being bridged. DO NOT CONNECT ANYTHING ELSE
TO EITHER OF THESE BLACK OUTPUT TERMINALS!
The red (positive) output terminal of the non-inverted channel (the one whose
polarity is set to zero degrees) is connected to the speakers positive (+)
terminal. The red (positive) output terminal of the inverted channel (the one
whose polarity is set to 180 degrees) is connected to the speakers negative (-)
terminal.
ALTHOUGH 6B CHANNELS ARE SHOWN, THE
SAME HOOKUP APPLIES TO 9B CHANNELS
WARNING! RISK OF HAZARDOUS ENERGY. MAKE PROPER SPEAKER CONNECTIONS.
SEE OPERATING MANUAL BEFORE USING.
HEAT
When two 6B channels are bridged the
power output can exceed 800 Watts.
Two 9B channels can provide over 300
Watts. When operated at these
elevated power levels there is a
possibility of the amplifier
overheating. When overheated they
will automatically be shutdown by
internal protection circuitry to prevent
any damage occurring to the
amplifier. To prevent overheating it
may be necessary to provide external
fan cooling especially if the amplifier
is installed in an enclosed cabinet and
operated at or near maximum power
levels.
