6. Mode
The MODE button steps
through the modes of the
bank currently in use. Using
its Expanded modes, the
CP-3
PLUS
can have as many
as 45 operating modes: Pre-
sets 1-15 are configured at
the factory, those labeled
User A1-15 and User B1-15
are available for storage of
modes customized by the
user.
In Standard operation, 5
modes are available.
7. Volume
The VOLUME buttons adjust
the level of all channels si-
multaneously. These buttons
assume the function of the
volume control on your
preamp or receiver.
8. Main Mute
MAIN MUTE turns off all out-
puts and lights both MAIN
and EFFECTS MUTE LEDs.
3. Alphanumeric Display
The alphanumeric LCD (liq-
uid crystal display) shows
both the mode that is running
and its modifiable parame-
ters. The contrast of the LCD
can be adjusted for optimum
visibility. See Page 18. (A
video on-screen display is
described on Page 19.)
4. Infrared Receiver
The small unlabeled window
to the right of the LCD houses
the infrared receiver used by
the CP-3
PLUS
to detect signals
from the remote controls.
5. Bank
In Expanded operation, the
BANK button cycles through
the Preset bank and two User
banks (A&B) where custom-
ized modes can be stored.
The mode number doesn't
change: if you are using Pre-
set 9, pressing BANK once
switches to User A9, press-
ing it again switches to User
B9, pressing it again
switches back to Preset 9. In
Standard operation, the
BANK button is inoperative.
1. Input
The four INPUT buttons are
used to select which input is
processed by the CP-3
PLUS
.
Pressing any one of these
buttons will select that input
and light the LED above it.
The CP-3
PLUS
can be pro-
grammed to engage a spe-
cific operating mode for each
input, so changing inputs
may change the mode being
used. See Auto-Mode Load,
Page 24.
2. Input Level Display
The INPUT LEVEL display
monitors the level in the
CP-3
PLUS
's digital encoding
circuits and is used to indi-
cate the correct Dolby level
for video sound sources
(marked by the double-D
symbol between the LEDs.)
When correctly set, the loud-
est passages will light the
entire row of green LEDs, the
two yellow ones, and occa-
sionally flash the red peak
LEDs at the top. See Page
22, Setting Input Levels. (The
input level meters can be
turned off to eliminate dis-
traction — See Page 19.)
9. Effects Mute
EFFECTS MUTE turns off all
signals added by the CP-
3
PLUS
, lights the yellow EF-
FECTS MUTE LED on the
front panel, and displays “EF-
FECTS MUTED.” This by-
passes all signal processing
in the CP-3
PLUS
except level
control, and is the simplest
way to play “normal” two-
speaker stereo. Press again
to restore normal operation.
10. On/Off
ON/OFF alternately puts the
CP-3
PLUS
into and out of
standby mode. Turning the
CP-3
PLUS
off with this button
(or with either remote) deac-
tivates the unit while leaving
power to the signal process-
ing circuitry to keep it at opti-
mum operating temperature.
Although this switch may be
used to turn the CP-3
PLUS
off,
it is important that the
CP-3
PLUS
be turned on with
the remote control that will be
used during each listening
session. If the front panel
switch is used to turn on the
CP-3
PLUS
, it will resume op-
eration in whichever mode
(Standard or Expanded) it
was last in.
