Thank you for purchasing a Bryston B60 integrated
INTRODUCTION
Thank you for choosing a Bryston Preamplifier. Bryston
welcomes any suggestions you may have, or comments
regarding the operation of your amplifier. We con-
sider you, our customer, to be Bryston’s most important
resource, and your opinion is very much appreciated.
There are three different variations of the BP6 preamp:
● BP6 this is the base model
● BP6DA includes a D/A converter with an SPDIF input
● BP6P includes Bryston’s discrete moving-magnet
phono equalization stage.
N.B.
We recommend that you keep all original packing mate-
rials in the event that your Bryston preamp may need to be
returned for servicing. Any of the original packaging materials
that Bryston needs to supply in order to safely return serviced
equipment may be chargeable.
SETUP
Bryston BP6 pre-amps with the remote control option
should be placed where there is a direct line-of-sight
between the hand-held remote and the remote infra-red
sensor eye located on the left side of the pre-amplifier’s
front panel.
If you purchased the BP6P, which includes a Phono
section, avoid placing the preamplifier directly on top of
your power amplifier. Power amplifiers usually employ
large power supplies and the transformers) in the power
supplies can cause interference (hum) with the sensitive
phono section inside the pre-amp.
ANALOG AUDIO CONNECTIONS
GENERAL
All inputs and outputs employ fully discrete active cir-
cuitry and all input and output connectors have gold
plated contact surfaces. Only cables with high quality
gold plated connectors should be used with your pre-
amp to avoid noise and distortion from the corrosion
that will eventually appear on poorly plated cable con-
nectors.
Connect the pre-amplifier’s left and right outputs to the
appropriate left and right input jacks on your power
amplifier. Connect your CD player, tuner, tape deck,
video recorder, or laser disc, etc. to the specific left/
right preamplifier inputs. With the phono stage equipped
model (BP6P) connect your phono cables. to the phono
input jacks. If your turntable leads have a separate
ground wire, it may be connected to the ground post
adjacent to the phono inputs on the rear panel.
The tape loop may be used to insert a surround sound
processor, cassette tape deck or video tape recorder into
your system. Plug your tape deck or external processor’s
input cables into the “To Tape” jacks, and the processor
or deck’s output cables into the “From Tape” jacks at the
rear of the pre-amp. The tape or processor loop may be
operated via the “Tape/normal” toggle switch located on
the front panel of the preamplifier.
ANALOG AUDIO INPUTS
BP6 preamplifiers are equipped with 4 pairs of RCA
input connectors and one pair of RCA tape input jacks.
All RCA jacks are gold plated. Input sensitivity is 500mV
and input impedance is 50K ohms. See also PHONO
EQUALIZATION MODULES for Phono input details.
ANALOG AUDIO OUTPUTS
BP6 preamplifiers are equipped with 2 pairs of parallel
RCA output connectors and one pair of RCA tape out-
put jacks; see Tape Loop section below. All RCA jacks
are gold plated. Input sensitivity is 500mV and input
impedance is approx. 50K ohms. See also PHONO
EQUALIZATION MODULES for Phono input details.
TAPE LOOP
Tape Outputs: The “TO TAPE” outputs are selected
by the rotary “SELECTOR” knob and are provided as a
recording output. This feed is unaffected by the operation
of other front panel controls.
Tape Inputs: The “FROM TAPE” (unbalanced RCA)
inputs are useful for monitoring tape playback or pro-
cessed signals. Moving the “Tape/Normal” toggle to
Tape’ (up) position monitors the recorded signal on
recorders equipped with a separate playback head, or
the processed signal when using a signal processor.
Input sensitivity is 500mv, input impedance is 10K ohms.
HEADPHONE JACK
A quarter inch stereo (3 conductor) headphone jack is
located on the front panel of all BP6 pre-amps. We rec-
ommend the use of headphones with input impedances
between 50 ohms and 600 ohms. Headphones with an
impedance above 600 ohms may experience some prob-
lems attaining sufficient volume levels. The main outputs
will be muted when a phone plug is inserted into the
headphone jack. TAPE outputs are not muted. You can
adjust the volume setting of the headphones by using
the volume control on the front of the BP6 or by utiliz-
ing the remote control if your unit is so equipped. The
headphones cannot be muted with the remote control
unit. Use caution when disconnecting the headphones
as the loudspeakers will be immediately re-connected
at the volume level indicated by the front panel volume
control.connected at the volume level indicated by the
front panel volume control.
