FRONT PANEL CONTROLS:
MUTE/NORMAL TOGGLE SWITCH:
Mutes or releases
mute at the main outputs, (not ‘To Tape’ outputs), without
changing the volume control setting, each time pushed.
POLARITY/INVERT TOGGLE SWITCH:
Reverses polar-
ity at main outputs each time pushed. (GREEN LED indi-
cates positive polarity, YELLOW LED indicates inverse
polarity).
VOLUME CONTROL:
Rotary control varies the output
level to the ‘MAIN OUTPUTS’, (does not effect ‘TO TAPE’
outputs). BALANCE: Rotary control adjusts the left-versus-
right channel levels.
BALANCE CONTROL:
is a
tailored-inflection type which
has very gradual action near the center of rotation allow-
ing fine adjustments to the stereo image. For convenience
the electrical center of the control is detented.
SOURCE SELECT SWITCH:
Rotary switch determines
which input will appear at the “TO TAPE” outputs for
recording or processing, as well as determining which pro-
gram is available at the Main outputs. (When the “TAPE/
SOURCE” switch is in “Tape” position, “FROM TAPE”
inputs appear at Main Outputs).
MONO/STEREO SWITCH: “
Stereo” position provides
two-channel stereo at the Main outputs. ‘Mono’ position
sums the main outputs to monaural. The ‘TO TAPE’ out-
puts are always stereo. (Switch not present on “-MC” or
“-DA” models).
MC/MM PHONO SWITCH:
This switch is present on the
BP26MC models only. It allows the selection of either
Moving-Magnet or Moving-Coil phono equalization. This
switch takes the place of the “Mono/Stereo” toggle switch
on other BP26 models.
DAC-1/DAC-2 TOGGLE SWITCH:
Only on BP26DA mod-
els, this switch determines which of the two SPDIF digital
audio inputs is processed and then sent to the tape and
main outputs. The SOURCE select switch must also be in
the “DAC” position to monitor the digital audio inputs.
TAPE/SOURCE SWITCH: “
Source” position monitors
whichever input is selected at the rotary SOURCE selec-
tor rotary switch. “Tape” position provides monitoring of the
“FROM TAPE
”
input for A/B comparison with the source.
Should an external processor or equalizer be connected in
the tape loop, the ‘TAPE / SOURCE” switch will act as an
in/out switch for the external equipment.
