6. PEAK Indicator
These indicators light in red when the input signal level is too high. They go on at 6 dBm before clipping, warning
that the signal is approaching clipping levels. The signal monitored by the PEAK indicator is post-EQ and post-
fader (please refer to the Block Diagram
cator does not light up too frequently.
7.Channel Faders
Each fader adjusts the output for its corresponding channel. The black areas along the fader markings make it easy
to determine the range within which the faders can be set to avoid distortion and noise.
* Output is normal when the fader is set to the 0 position.
* Even when nothing is connected to the INPUT jack of a channel, noise may be heard if the SENS knob is rotated toward the
right and the channel fader raised, so you should turn the SENS knob and channel faders of unused channels to their mini-
mum position.

8.DSP PROCESSING
DIGITAL REVERB
The CPM-300 offers four types of internal digital reverb. (
ANTI FEEDBACK
Feedback is automatically detected and eliminated the instant it begins. (
9.SEND/RETURN
SEND Knob
This takes the signals adjusted by means of the individual channel SEND knobs (3), mixes them, adjusts the output,
and sends it to the DSP PROCESSING (internal digital reverb) (8).
An identical signal is also sent to the SEND jack in the connector section. (
* Output is normal when the knob is set to the 0 position.
RTN (Return) Knob
This adjusts the input signal from the connector section's RETURN jack. (
* Input is normal when the knob is set to the 0 position.
10.MASTER LEVEL Meter
This meter indicates the mixer section's output level (MIXER OUT level). When the 0 indicator is lit, it indicates that
the output level is at +4 dBm.
The output of the mixer section is sent to the amplifier section, and this signal is output from the speaker terminals
→
( p. 9) on the rear panel at 100 watts (when speakers with of 8 ohms are connected).
* When cables are connected to the AMP IN jacks
the mixer section is isolated. (
11.POWER Indicator
This indicator lights up when the power up on.
12.PHONES Knob
This adjusts the headphones volume.
* The signal used for the headphones is taken before the MASTER faders (pre-fader) (please refer to the Block Diagram
* The headphones of this unit may be capable of producing sound levels that could cause permanent hearing loss. Do not oper-
ate for a long period of time at a high volume level, or at a level that is uncomfortable.
13.MASTER Faders (LEFT/RIGHT)
These adjust the final output level of the mix. The black areas along the fader markings make it easy to determine
the range within which the faders can be set to avoid distortion and noise.
* Output is normal when the fader is set to the 0 position.
* The CPM-300's power amp features a built-in limiter circuit. This monitors the signal from the CPM-300's mixer to prevent
clipping in the amp that can cause distorted sound and blown speakers.
