recording output. This feed is unaffected by the opera-
tion 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
or the processed signal when using a signal proces-
sor. Input sensitivity is 500mv, input impedance is 10K
ohms.
PHONO EQUALIZATION MODULE
(Optional)
(Optional)
:
Bryston’s phono equalizer circuitry is available in both
B60 and B60R integrated amplifiers. It features highly
accurate equalization, extremely low noise and distortion
and provides headroom margins sufficient to prevent
overload from any known phono source. If your turntable
provides a separate ground lead , system noise may be
minimized by connecting it to the ground post adjacent
to the phono inputs on the rear panel. Input impedance
is 50K ohms and sensitivity is 5mV.
DIGITAL AUDIO INPUT MODULE
(Optional)
(Optional)
:
The B60DA / B60RDA models contain an SPDIF
compatible digital audio input (RCA jack). To select this
input set the rotary “SELECTOR” switch to the “DAC”
position. Once this input is selected operation of the
digital-to-analog convertor is fully automatic. The digital-
to-analog convertor can handle input sample rates from
16KHz to 108KHz, and word lengths of 16, 18, 20 or 24
bits.
FRONT PANEL CONTROLS:
VOLUME CONTROL:
Rotary control varies the out-
put level to the ‘MAIN OUTPUTS’, (does not effect ‘TO
TAPE’ outputs). BALANCE: Rotary control adjusts the
left-versus-right channel levels.
BALANCE
CONTROL:
BALANCE CONTROL: BALANCE
is a
tailored-inflection type
which has very gradual action near the center of rota-
tion allowing fine adjustments to the stereo image.
For convenience the electrical center of the control is
detented.
SOURCE
SELECTOR
SWITCH:
SELECTOR SWITCH:SELECTOR
Rotary switch deter-
mines which input will appear at the “TO TAPE” outputs
for recording or processing, as well as determining
which program is available at the Main outputs. (When
the “TAPE/NORMAL” switch is in “Tape” position,
“FROM TAPE” inputs appear at Main Outputs).
TAPE/NORMAL
SWITCH: “
Normal
”
position monitors
position monitors
whichever input is selected at the rotary SELECTOR
switch. “Tape” position provides monitoring of the
“FROM TAPE
”
input for A/B comparison with the
” input for A/B comparison with the ”
source. Should an external processor or equalizer be
connected in the tape loop, the ‘TAPE / NORMAL”
switch will act as an in/out switch for the external equip-
ment.
LOUDSPEAKER OUTPUTS:
Output connectors consisting of two pairs of red/
black 5-way binding posts, which can accept standard
banana plugs, spade lugs, pins or bare wire. Since the
binding posts are gold plated we recommend gold plat-
ed connectors also be used on the speaker cables for
optimum long term low distortion performance. we also
recommend that loudspeaker wire of at least 16 gauge
be used for maximum performance.
B60 REMOTE CONTROL
The Bryston B60 includes a hand
held remote control unit. It pro-
vides for remote volume control
and full signal mute. the Volume
control is a motor driven design.
This approach ensures lower dis-
tortion and other noise artifacts
than VCA’s and DAC’s.
Pressing the MUTE button on
the remote control will fully mute
the output from the preamplifier
section. The power LED on the
front panel will turn from green to
red. To un-mute the amplifier sim-
ply push the MUTE button again or
press the volume UP button.
The mute function on the remote
control will not function if using headphones.
The hand held remote unit is battery operated. To
change the battery remove the bottom cover plate by
unscrewing the Philip’s head screws and replace the 9
volt battery carefully observing the polarity of both the
battery and battery clip.
We recommend maintaining a direct line-of-sight
between the hand held remote and the front of the B60R
to ensure the most efficient operation of the remote fea-
tures.
