Introduction; Setup; Connections; Inputs & Outputs - Bryston B135 Owner's Manual

INTRODUCTION

Thank you for purchasing a Bryston B135 integrated amplifier. We are confident it will provide you with many
years of musical enjoyment. We would welcome any suggestions or comments you may have regarding the
operation of your Bryston amplifier.
In the unlikely event that your amplifier may require service Bryston recommends that you retain the original
shipping box and packaging material for future use if required.
SETUP RECOMMENDATIONS
You may place your B135 integrated amplifier in any convenient location. If you have purchased the optional
infra-red remote control, make sure you position the amplifier to maintain a direct line-of-sight between the
hand-held remote and the IR sensor eye located on the front panel. If plugged in the B135 will remain in
standby indicated by the RED power LED on the front panel.
The amplifier is powered up by engaging the power button located on the front panel of the B135 or by
depressing the POWER button on the hand held remote control unit.. The B135 will power-up momentarily
with mute engaged, indicated by the mute LED turning red on the front panel; it will then turn off within a few
seconds. The POWER LED will stay lit green indicating normal operation.

CONNECTIONS

MAINS POWER INLET:
Mains power is connected to the B135 through an IEC-C14 power inlet on the rear panel. This inlet mates
with an IEC-C14 connector. Use only an approved power cord for your location. Before connecting or discon-
necting the power cord, make sure that the unit is powered off.
POWER CONDITIONERS:
Bryston urges caution in choosing a power conditioner for your audio/video system. Large power amplifiers
can draw very substantial current from the wall plug, and many so-called power conditioners can in fact hin-
der the supply of current by inserting resistances in series with the line cord. However, there are now power
conditioners that can reduce or eliminate RF and 'hash' from the AC supply and may actually improve current
delivery to your system. This type of power conditioner (exemplified by 'TORUS' Power Conditioners) uses
the energy storage in a large toroidal tranformer to provide high instantaneous power and reduce the sub-
stantial AC output resistance of the wall socket and house wiring. This resistance can be in the range of 0.5
to 1 Ohm and is typically reduced to only a few milliOhms by the Power Conditioner. That in turn considerably
reduces Voltage drop in the power line on high current surges and quite substantially increases the stability
of the power line improving audio (and video) focus, precision and clarity.
LOUDSPEAKERS:
Connect your loudspeakers, ensuring that the positive (red) and ground (black) terminals (gold-plated 5-way
binding posts) on the Bryston B135 integrated amplifier are connected to the positive and ground terminals
on your loudspeakers. Make certain the left and right speaker outputs on the amplifier are connected to your
appropriate left and right loudspeakers.
SEPARATE PRE-AMP OUT & POWER AMP IN JACKS:
These two pair of RCA jacks allow for the independent use of the stereo amplifier section within a multi-channel
audio or video system. On the rear panel there are connections labeled 'PRE AMP OUT' (preamplifier output)
and 'POWER AMP IN' (power amplifier input) along with two slide switches (one per channel) labeled "Separate/
Connect". This feature allows you to "separate or connect" the preamplifier section of the B135 from the power
amplifier section thus producing a separate stereo preamp and separate stereo power amplifier.
WIRED (SERIAL DATA) REMOTE CONTROL:
There is one RS-232, one AUX IR input and two 12 volt trigger output connections as well. The RS-232 is bi-
directional and allows for future software downloads from the Bryston website. It also interfaces with control
systems such as Crestron and AMX.
