Crest Audio CPM 2462, Operating Manual

Channels 9-16 and 17-24 co-exist in on the CPM 2462. Channels 9-14 are mono mic input channels
similar to channels 2-8 but with a fixed frequency mid EQ control and without the direct out and
insert. However, occupying the same space are stereo line inputs 17-22. A switch on each of these
channels determines whether these channels work independently or whether the mic input is muted
and the line inputs are routed (mono) through the full featured channel strips 9-14. The line input
channels have their own subgroup (group 5-6) that can in turn be routed to the other subgroups or
to L/R.

Channels 15-16 and 23-24 are nearly identical to their next door neighbors except that channels 15
and 16 are full stereo channels. When stereo line channels 23 or 24 are routed through 15 or 16,
the stereo signal is maintained. In all of the stereo line channels 17-24, the rotary line level control is
used as the mix control when assigned to group 5-6 or as an input trim control when routed through
channels 9-16. The diagrams showing these channels help show how this routine works.

NOTE:

These additional stereo line input add tremendous versatility to the CPM 2462 by providing

eight stereo inputs in addition to the 16 mic inputs.

MIXES

When we speak of the various mixes on the CPM 2462 we are basically speaking of the resultant

signals from the various buses found at the CPM 2462 outputs. Let’s take a look at the individual 

output sections.  

Main Stereo L/R and Mono Outputs

The first and most common section is the master L/R/Mono output section. In this section the 

CPM 2462 provides separate Left and Right outputs (both balanced XLR and unbalanced 1/4").

Each signal goes through a final pre-fader insert jack to allow for the placement of master effects in

the master L/R signal chain. In addition, the Left and Right signals are also mixed (L+R) to create a

balanced (XLR) Mono signal. All three outputs are controlled by the master Left and Right faders.

The Mono output is also controlled by its own level control, the Mono Out Level. Use this control to 

adjust the level of the Mono Out and use the master Left and Right faders to adjust the balance

as desired. The following block diagram shows the master L/R/Mono output section.
