CSM8/12/16/24 Console Mixer
The Input Channels:
1. LOW Z INPUT: The signal output from a low impedance microphone or a low
impedance line level signal (such as a line out signal from an instrument amplifier) may be connected here by means of a shielded cable terminated with a
male XLR plug. Pin 2 = “+,” pin 3 = “–,” and pin 1 = shield.
2. HIGH Z INPUT: The signal output from a high impedance microphone or a line
level signal (such as an instrument, rhythm machine, tape deck, etc.) may be
connected here by means of a shielded cable terminated with a male 1/4” plug.
Tip = “+,” ring = “–,” and sleeve = shield.
1
2
3
3. INSERT: A signal processor may be connected here by means of a shielded
stereo signal cable or shielded “Y” cord. (See page 8.) Ring = send, tip = return,
and sleeve = ground.
5
4. PEAK/SIGNAL LED: This LED will illuminate green when a signal is present at
the High or Low Z inputs. When the signal nears clipping, the LED will illuminate red. (See Gain control, #5.)
6
5. GAIN: Use this control to set the input signal level for the channel. Adjust this
control so the peak LED (#4) flashes on strong signal peaks.
4
6. HIGH: Use this control to adjust the high frequency level for the channel. This
control allows for 15dB of cut or boost at 10kHz. Typical equalization diagrams
are shown on page 7.
7
8
9
7. MID: Use this control to adjust the midrange frequency level for the channel.
This control allows for 15dB of cut or boost at 2kHz. Typical equalization diagrams are shown on page 7.
10
8. LOW: Use this control to adjust the low frequency level for the channel. This
control allows for 15dB of cut or boost at 100Hz. Typical equalization diagrams
are shown on page 7.
11
12
9. AUX 1, AUX 2: Use these controls to set the channel’s output signal level at the
aux 1 and aux 2 send jacks (#17, page 5). These are pre-EQ, pre-fader, and are
typically used as monitor sends. Examples of some typical connection methods
are shown on pages 8–13.
10. AUX 3, AUX 4: Use these controls to set the channel’s output signal level at the
aux 3 and aux 4 send jacks (#17, page 5). These are post-EQ, post-fader, and
are typically used as effects loop sends. Examples of some typical connection
methods are shown on pages 8–13.
13
14
11. PAN: Use these controls to set the amount of the channel’s output signal sent to
the left and right master faders (#30, page 6) and the left and right balanced output jacks (#15, page 5).
12. MUTE: This switch, when depressed, mutes the channel’s output signal sent to the
left, right and mix master faders (#30, 31, page 6).
13. PFL: This switch, when depressed, sends the channel’s post-EQ, pre-fader signal
to the headphones jack (#28, page 6) and the PFL output jack (#18, page 5).
14. FADER: Use this control to set the channel‘s signal level output sent to the left,

19. AUX RETURN JACKS: Use these jacks to return the
processed signal from an external effect into the master
mix. These jacks are stereo 1/4” connectors – ring =
right, tip = left, sleeve = shield.
20. POWER: This switch applies the power to the mixer. The
mixer is on when the top of the switch is depressed, off
when the bottom of the switch is depressed. The adjacent LED illuminates when the power is on.
29
30
16. TAPE IN/TAPE OUT JACKS: Use these jacks to connect
to the record and playback jacks of a cassette tape deck.
Because the tape in jacks are fed directly into the left
and right master faders, use the tape deck’s output level
control or an in-line attenuator to adjust the level of the
playback signal.
17. AUX SEND JACKS: Use these jacks to send the aux signals to your monitor amps and/or external effects. Aux 1
and 2 are sends only, while aux 3 and 4 can be used as
an effects loop along with the aux 3 and 4 return jacks
(#19). (See pages 8–13). The mix for each aux send jack
is set by the channel aux controls (#9, 10). The master
aux 1 fader (#30, page 6) sets the overall signal output
level for the aux 1 jack, while the aux 2, 3 and 4 send
controls (#24, page 6) set the overall signal output level
for the aux 2, 3 and 4 jacks.
20
22
15. LEFT, RIGHT AND MIX BALANCED OUTPUTS: Use
these jacks to send the mixer’s output signal(s) to the
house power amplifier(s) (see pages 9–13). For the XLR
jacks, pin 2 = “+,” pin 3 = “–,” and pin 1 = shield. For
the 1/4” jacks, tip = “+,” ring = “–,” and sleeve = shield.
32
21: OUTPUT LED METERS/PEAK INDICATORS: These LED
meters monitor the output signals sent to the balanced
output jacks (#15). The meter selector switch (#22)
determines whether the meters monitor the left and right
output signals or the aux 1 and mix output signals.
When the LEDs illuminate into the upper red areas, the
signals are near clipping and may need to be reduced to
avoid distortion.
22: METER SELECTOR SWITCH: When the switch is in the
out position, the LED meters (#21) monitor the left and
right output signals. When the switch is depressed, the
LED meters monitor the aux 1 and mix output signals.

23: PHANTOM POWER: This switch, when depressed, applies 48
volts DC to pins 2 and 3 of the each channel’s low Z input jacks
(#1, page 4) to accommodate microphones which require a
source of phantom power for proper operation. (Mics not
requiring phantom power are not affected by the presence of the
DC voltage.)
24. AUX SEND LEVELS: Use these controls to set the output levels
for the signals at the aux 2, 3 and 4 send jacks (#17, page 5).
20
25. AUX RETURNS: Use these controls to adjust the level of the
signals from the aux 3 and 4 return jacks (#19, page 5).
26. AUX PANS: Use these controls to set the balance of the aux 3
and 4 return signal sent to the left and right master faders (#31).
21
27. HEADPHONES/PFL LEVEL: Use this control to adjust the output
signal level at the headphones/PFL jack (#28).
22
28. HEADPHONES/PFL JACK: Use this jack to connect a pair of
stereo headphones to the mixer. The signal at this jack is taken
from the PFL bus, therefore the channel PFL buttons must be
depressed in order to hear their signals through the headphones.

30. AUX 1 MASTER FADER: Use this control to set the overall output signal level at the aux 1 send jack (#17, page 5). A fader has
been chosen to provide ease of control of aux 1 since this is typically used as an output signal for the stage monitors.
29
30
31
29. PFL LEFT/RIGHT/MIX: These switches, when depressed, send
the corresponding PFL signals to the headphones/PFL jack (#28)
and to the PFL output jack (#18).
32
31. LEFT/RIGHT MASTER FADERS: Use these controls to set the
overall output signal levels at the left and right balanced output
jacks (#15, page 5), as well as the signal level sent to the mix
master fader (#32).
32. MIX MASTER FADER: Use this control to set the overall output
signal level at the mix balanced output jacks (#15, page 5). The
left and right master faders (#31) must be set at an appropriate
level so that a signal of sufficient amplitude is sent to the mix
master fader.

CSM8/12/16/24 Console Mixer
Equalization Diagrams:
Each input channel of the CSM8/12/16/24 has three bands of equalization which let you alter the tonal characteristics
of the input signal. The EQs may be used to add “color” or to compensate for inadequacies of the original signal. They also
may be used to cut frequencies to help eliminate unnatural sounds or to de-emphasize over-pronounced tones, and to help
prevent acoustic feedback. Each EQ has a range of 30dB (+/-15dB).
•The high EQ for each channel is a “shelving” type, with an action point (+6dB) at 6kHz, reaching maximum
effect at 10kHz and above.
•The middle EQ for each channel is a “peaking” type, which affects frequencies from 800Hz to 5kHz, centered
at 2kHz.
•The low EQ for each channel is a “shelving” type with an action point (+6dB) at 250Hz, reaching maximum
effect at 100Hz and below.

Differences in Cable Types:
This manual makes reference to different types of cables; in particular, balanced and unbalanced signal cables and
speaker cables. These are not the only types of cables associated with sound reinforcement, but they are similar enough to
each other to warrant a more descriptive explanation. For example, the three 1/4”-terminated cables below may look alike
at first, but upon closer examination their differences become apparent.

CSM8/12/16/24 Console Mixer
Connecting External Signal Processors:
There are several ways to use external signal processors with the CSM8/12/16/24. Each of the mixer’s input channels has its
own Insert jack, allowing a processor to be used on that particular channel. Figures 1 and 2 below show two ways of connecting a signal processor to the channel Insert jacks.
The mixer’s master section has two stereo effects loops available (Aux 3 and Aux 4), allowing a processor to be added to any
or all of the input signals. Figures 3 and 4 below show the basic connection of two types of stereo processors to the aux
loops.
Each channel’s Aux 3 and Aux 4 levels control the amount of signal sent from each channel to the aux loops. The master Aux
3 and Aux 4 Send, Return and Pan control the amount of signal sent to the processor, the amount of processed signal
returned to the mix, and how much of the processed signal is applied to the left and right output signals.
(See pages 4 through 6 for additional information on the insert jacks, the aux loops, and their controls.)
