INTRODUCTION:
Thank you
for purchasing a Bryston B100 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 B100 integrated amplifier in any convenient location. Make sure you position the ampli-
fier to maintain a direct line-of-sight between the hand-held remote and the remote sensor eye located on
the front panel. If plugged in the B100 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 B100 or by
depressing the Power button on the hand held remote control unit.. The B100 will power-up momentarily with
mute engaged, indicated by the mute LED turning red on the front panel. It will then turn green signifying
normal function.
CONNECTIONS:
LOUDSPEAKERS
:
Connect your loudspeakers, ensuring that the positive (red) and ground (black) termi-
nals (gold-plated 5-way binding posts) on the Bryston B100 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.
PASS THROUGH:
There is a ‘Pass-Through’ feature allowing you to easily accommodate the integration of a
surround sound processor into your system and still maintain the control functions available on the front panel
of the B100. It also allows 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). This feature allows you to "separate or connect" the preamplifier sec-
tion of the B100 from the power amplifier section by activating the rear panel switches (one for each chan
nel).
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-d
irectional and allows for future software downloads
from the Bryston website. It also interfaces with control systems such as Crestron and AMX.
CHASSIS GROUND:
A ground screw terminal is provided on the rear panel if the MM internal Phono stage
is installed (model B100-P).
12 VOLT TRIGGER CONNECTOR:
These 12Vdc control outputs allow the B100 to exert on/off control
over compatible equipment.
See “REMOTE POWER CONTROL” for more information..

HEADPHONE JACK:
There is a quarter inch headphone output jack available on the front panel of the
Bryston B-100 integrated amplifier. The headphone output is driven directly from the preamplifier section uti-
lizing separate headphone buffers. Inserting the headphone jack mutes the loudspeakers automatically (indi-
cated by the mute LED on the front panel turning red). The B100
PREAMP OUT
is also muted.
PREAMP OUT is also muted.PREAMP OUT
You can adjust the volume setting of the headphones by using the volume control on the front of the B-100
integrated amplifier. You may also utilize the remote control unit to adjust headphone volume. The headphones
cannot be muted with the remote control unit or the front panel Mute. Only headphones with impedances of
greater than 50 ohms should be used.
AUXILIARY IR INPUT:
This mono 1/8” (3mm) phone jack allows a direct connection to equipment whose
remote control system provides an output from their infra-red LED drive circuit. The signal connected to this jack
should be ≥1.8Vdc and ≤ 9Vdc. The

HAND-HELD INFRA-RED REMOTE CONTROL:
The Bryston model B100 comes standard with a full function hand-held remote control unit.
The hand held remote unit is powered by two “AAA” batteries. To change the battery remove
the bottom cover plate by removing the four Philips screws on the rear of the remote unit.
Ensure that the batteries are correctly oriented and properly seated in the battery holder.
The B100 remote is a full function remote. It allows selection of all sources, volume up or
down (the volume control is a motor-driven design), mute ,left/right balance, power on/off
and discrete code entry.
We recommend maintaining a direct line-of-sight between the hand held remote unit and the
front of the B100 to ensure the most efficient operation of the remote features.

WIRED RS232 REMOTE CONTROL:
Using the DB9-female connector at the rear of the unit, the B100 can receive commands via a null modem cable at
9600 baud, 8 data bits, no parity and 1 stop bit (9600,8,N,1). Valid commands will return the “>” character indicating
that the unit is ready to receive a new command. An invalid command will return the “!” character. These serial data
commands are as follows:

DIGITAL-to-ANALOG (D/A) CONVERTER OPTION:
The B100-DA comes equipped with stereo Digital-to-Analog converter (D/A or DAC) module. This module is
also retrofittable to standard B100 units.
A unique feature of the B100-DA is its ability to utilize up to four independent digital sources (two SPDIF and
two TOSLINK). These four digital inputs can be accessed by selecting

The source LED’s will turn GREEN when a PCM digital bit stream is present. If there is no bit stream available
or an incorrect bit stream (NON-PCM) the LED will turn RED.
You may re-select Analog by simply depressing the
ANALOG/DIGITAL
button once more and the LED will
extinguish.
All of the above functions are available from the hand held remote control as well .
MOVING-MAGNET PHONO STAGE OPTION:
The B100-P contains a
moving magnet
phono stage. The Phono Stage is modular and can be added to the stan-
dard B100 model later if required by your Bryston dealer.
Bryston’s MM Phono section features state-of-the-art accuracy in equalization, extremely low noise and distor-
tion, and provides headroom margins sufficient to prevent overload from any known phono source. To access the
Phono section simply plug your left/right turntable interconnect leads into the left/right
AUX-1/PHONO
inputs on
