phantom power, -25 dB pad and polarity in addition to a high
quality mic pre-amp that features high headroom, high slew rate
and excellent CMRR performance. Also provided on all mono
inputs is a high-pass filter that is variable between 20 and 400 Hz.
Separate ¼ inch jacks are provided for a pre-EQ balanced send
and a balanced return at a nominal level of +4 dBu. Insert on/off
switching is also provided to allow permanent patching.
Four-band EQ is provided with sweep able high and low frequency
points and selection between shelving and peak, full parametric
control on the mid bands with frequency sweeps and Q control.
The entire EQ circuit can be bypassed by disengaging the EQ ON
Switch.
12 auxiliary sends are divided into 3 versatile sets. 1-4 being fixed
mono sends with their own pre/post switch. 4-10 are switch able
8 channels. Each channel includes switches for; 48 volt
between dual mono and stereo with pre/post switches per pair
and 11 & 12 are fixed stereo with pre and post selection for crucial
“In ear monitoring” applications. The default “pre” selection is
pre-fader/post EQ, but internal options allow this election to be
changed to pre-EQ.

A high quality 100 mm fader is standard on all inputs with 10
inputs via 8 individual assignment switches. Stereo panning
between group pairs can also be achieved by selecting the
“PAN ON” Switch.
Left/Right and Mono routing is done by pressing either the
L-R or M/C switches. A separate LCR switch is provided. This
allows panning between the Left, Mono and Right buses for
LCR applications.
dB of gain when in the full up position. Also provided is full
VCA control of the fader via a soft VCA assignment and mute
control locally or via grouping (see master control block).
The Solo switch allows PFL or AFL monitoring of the channel
selected from the master section. The Solo Switch is also
part of the VCA assignment (see master section). Other
monitoring functions include a 5-segment bar graph meter
for maximum visibility.

ight full-time stereo channels are provided standard on
all CV™ 20 frame packages with the ability to add more
E
modules on custom frame packages. The stereo module is
divided into two types of channels.
The first four stereo input channels allow mic and line level
inputs. Each of these channels feature switches for 48-volt
phantom power, -25dB PAD and polarity. Included on each
mic/line stereo inputs are two separate gain controls for Left
and Right signals as well as Left/Right sum mono switches.
The second four stereo input channels allow patching of 2
separate stereo line signals. The first gain control is a stereo
gain pot that controls the ¼ inch inputs and the second
controls the RCA inputs for “set and forget” operation.
Switching between the 2 inputs is via the Line 2 switch. A
selectable HPF filter is also provided on all dual line inputs
that can be selected between 75 and 150 Hz. Left/Right
and Mono switching is also available as well as a pre-source
balance pot to send a discreet blend of the stereo signal to
the Auxes.
A four-band sweep able EQ is provided on all stereo inputs
for full EQ control of stereo signals. The stereo inputs also
provide 12 Auxiliary sends with the first 4 sends switch able
to the Matrices. This allows the Matrix to be expandable
from 11 x 4 to 19 x 4.
Bus/Mute and VCA assignments are just like the mono
inputs. Monitoring is via the Solo bus and separate signal
and peak displays for each channel.

he Master Module block contains the main audio
T
buses and their associated controls, VCA masters
and Mute group/ scene masters and functions including
monitoring and talk back.
8 VCA masters are standard on all CV™ models.
Assigning Channels to a VCA is via “soft assignments”.
With a channel assigned to a VCA, not only can the
channel’s post fader level be controlled by the VCA
master but the channel can also be muted and soloed
from the master.
8 sub-groups are also provided on CV models for
conventional grouping each with their own 12 segment
bar graph metering. From the sub group signals can be
sent to the L/R and Mono buses. With the LCR switch
engaged panning between the Left, Right and Mono
buses can be applied for LCR applications.
Separate Left, Right and mono bus controls are also
provided on all CV units with 12 segment bar graph
metering for each bus.
Each subgroup and main bus can also be sent to 4 Matrix
outputs 1 & 2 Matrix buses being fixed mono and 3 and
4 being switch able from dual mono to stereo sends.
Matrix level control is provided via rotary controls with
Matrices 3 & 4 having the expanded ability to route to
Aux 11 & 12 to add post processed sub-grouped audio
to the Aux mix. The Matrix buses can also source
signals from the stereo inputs as well. This makes Matrix
expandable from 11 x 4 to 19 x 4.
12 Aux masters are also provided with separate solo and
mute switches for each master. Mutes of Aux masters
can be accessed locally or via the scene controls (see
scene controller). Each Aux master also has its own 12-
segment bar graph meter for monitoring purposes.

In FOH mode, the subgroups and main buses are controlled
by the respective 100mm fader. By pressing the fader reverse
switch on the subgroups or main buses, the fader controls
the Aux outputs for use in Monitor console applications. In
this mode, not only does the user have fader control on the
Aux outputs but VCA control over the Aux masters as well.
Included on each subgroup and main bus master is a full
dynamics section including a compressor, limiter and
downward expander/gate for processing of sub-grouped
mixes.
Each group pair can be stereo linked for Stereo processing
and can also be routed in stereo pairs to Auxes for processing
monitor mixes.
The Scene Controller microprocessor based mute and VCA
assignment system comes standard on all models. The Scene
Controller allows easy editing for mute and VCA assignment
automation via a “soft mute assignment, providing 8 manual
mute groups or scenes, 128 sequenced mute and VCA
assignment scenes that can be controlled locally via MIDI
and via RS485 devices. The Scene Controller settings can be
saved via a Jump drive with via the USB interface underneath
the armrest. The USB interface also has hooks to connect
a PC to program and control the Scene Controller via
Crest Audio’s NexSys® computer controlled audio systems
hardware.
3 levels of SOLO are provided on all models. Inputs can be
monitored all in AFL or In PFL. The input priority switch not
only clears an output being soloed when selecting an input but
also allows full-time PFL on the inputs and AFL on the outputs.
A SOLO CLEAR switch is provided to clear all channels that
are soloed as well as a solo off switch to eliminate the solo
bus from the monitors. The LAST PRESSED switch also
allows only one channel to be soloed at any given time.
Separate stereo Monitors outputs are standard on all CV
models. Level control of the monitor output is via a separate
High quality 100mm fader. The monitor output source can
be selected from either the main/group buses or external
input. A separate Headphone level is also provided. The
Headphone output is found underneath the armrest.
An alternate output is also provided on al CV models that can
be sourced from the main buses or any of the 4 Matrices. This
can be used to send the mix to any other location whether it
is a recorder, broadcast, or assisted listening devices.
