@ OVERLOAD INDICATOR
The Overload
Indicator will light when
the signal fed into the CPM reaches the
point which is 6dB lower than the clip
level.
@ GAIN
The Gain control is a continuously variable
rotary control
that is to be used
for
"trimming" the input signal level.
© TREBLE
@ BASS
These are used to boost or cut the portion
of the corresponding spectrum. At "<>"
position,
a flat characteristic
can
be
obtained.
© EFFECT SEND VOLUME
The position of this continuously variable
rotary control determines the amount of
the signal sent from the Effect Send Jack
to the connected unit.

* The pickup point of the Effect Send
signal is post channel volume.
@ PANPOT
The Panpot Control routs the signal sent
from the Input Jack to the left and/or
right mixing
buses.
By means
of the
Panpot Control, input signal can be sent
exclusively to one
mixing bus, or the
other, to both mixing buses equally, or
since the Panpot Control is continuously
variable
to both
mixing
buses
in any
relative proportion desired.
@ CHANNEL VOLUME
This knob controls the volume of each
channel independently.
© LEVEL INDICATOR
The Level Indicator detects the level of
the output signal. When
"OdB"
lights,
the
signal
of +4dBm
is being
sent
through
the Output Jack,
making
the
@ PRE OUT JACK
@ MAIN IN JACK
These jacks can be used to connect a
graphic equalizer to eliminate feedback
and/or to achieve acoustical compatibility
with different performance locations.
* The Pre Out Jack can also be used to
set up another power amplifier, and the
Main In Jack can be used when the CPM-
120 is used as a power amplifier for
other unit.
* When the CPM-120 is used as BTL
amplifier,
R does not work, but the Pre
Out Jack L sends out "L+R" signal.

This knob
controls the volume
of the
effect
sound.
Rotating
the
knob
clockwise will increase the volume.
@ HEADPHONES VOLUME
As you rotate this knob clockwise, the
headphones
volume will increase. This
knob allows separate level setting free
from the Master Volume.
@ HEADPHONES JACK
'
This is to connect headphones.
@ MASTER VOLUME
These
are
two
independent
controls
which control the volume of the left and
right channels, thus acting as an overall
volume controls for the CPM.

Switch,
the
power
amplifier section of the CPM-120 can be
changed from Stereo to Mono (BTL), or
Mono to Stereo.
@ SPEAKER JACK
@ SPEAKER TERMINAL
Use either of these to connect a speaker.
* To use the CPM-120 as BTL(Monaural),
connect the speaker to the MONO (BTL)
of the Speaker Jack.
* When both the Speaker Jack and the
Terminal
are simultaneously
used, the
Speaker Jack has priority, so there is not
output from the Speaker Terminal.
