Welcome

Thank you for your purchase of a Bryston B135³

the common assumption that such products are
inherently a compromise. High output power,
low distortion, exceptional sound quality and a
variety of features and options make the B135³
suitable for a wide variety of high quality audio
applications. Your feedback is important. We look to
our customers for a measure of success. Please feel
free to contact us with any feedback you may have

the B135³ is compatible with the Bryston BR-2 IR
remote control and two-way RS232 systems such as
Crestron and others.

inputs, adds two RCA digital inputs and two
Toslink optical inputs

• Optional MM phono stage.

• 135 watt x 2 channel output power into 8Ω

• Separate power supplies for each amplifier
channel and preamplifier

• Assignable home theater bypass (unity gain)
input.

Shipping Box and Packing Material

Please keep the original shipping box and all
packing material. This will ensure the B135³ 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
unit only in the original packing material, as the unit
is not insurable by carriers otherwise. Replacement
packing materials consisting of a shipping carton
with plastic foam inserts is available from Bryston
for a small fee.

Installation and Usage

Placement

The B135³ Integrated Amplifier is designed to
function optimally in a variety of circumstances
but careful placement will ensure long life and
outstanding performance. Do not place the B135³
nearby known sources of electromagnetic or radio
interference. Dress cables to avoid parallel runs of
power cables and audio interconnects. Usually,
using audio interconnects and speaker cables that
are as short as possible results in the best sound
quality.

Ventilation

Bryston has deliberately chosen to omit fans from
our amplifiers in an eort to minimize the noise
level in your listening environment. Instead, we use
only passive heat sinks which are fully capable of
maintaining a safe operating temperature of the
amplifier even under loud playback conditions. For
them to work most eectively, air must be
permitted to pass freely through the heat sink fins
and around the amplifier. Maintain a minimum of

3.5 inches of space to each side, top and back of the

amplifier when in use. Do not stack the amplifiers
immediately on top of one another in an enclosed
