C2VEQ-4 - 4-Channel Volume/EQ Control Card - Special

C2VEQ-4
4-Channel Volume/EQ Control Card
The C2VEQ-4 provides a very simple solution for adding professional
quality volume control, equalization, and signal routing to any card
frame-based Crestron 2-Series control system. In the space of a single
Y-bus expansion card, the C2VEQ-4 packs four channels of digital
volume and tone control, four 12-band graphic/parametric equalizers,
and a fully-adjustable 4x4 matrix mixer. Dual DSPs and 24-bit 96 kHz
A/D and D/A converters attain high-end audio performance perfectly
suited for a multitude of applications in boardrooms, auditoriums,
night clubs, and homes.
The C2VEQ-4 is controllable through any Crestron touchpanel, keypad,
handheld remote, or e-Control®2 user interface, with true feedback
provided for every parameter. Mixer and EQ settings are easily
configured and adjusted through Crestron's Media Tools software (part
of Crestron Toolbox) and saved in presets stored onboard the C2VEQ-4
card.
Volume/Tone Control
In its most basic configuration, the C2VEQ-4 provides four individual
audio channels which may be operated independently or linked for
stereo operation. Each channel includes adjustments for volume, bass,
treble, and mute, with definable ramp times and scaling for fully
customized operation. Protective relays on each output are included to
prevent "thumps" during power-up and provide 100dB attenuation for
dead-silent muting.
Matrix Mixer
The 4x4 matrix mixer allows any input to be routed to any or all
output channels with full control over each individual level. Using
the C2VEQ-4, up to four line-level sources may be mixed and
distributed to up to four destinations, with each destination
receiving a different mix as needed. A master volume adjustment is
also included to make overall level adjustment a snap.
Five mixer presets may be stored onboard the C2VEQ-4, with additional
presets possible within the control system if needed. Such power and
flexibility makes the C2VEQ-4 ideal for a host of mixing and
multi-zone applications.
Graphic/Parametric EQ
Each of the four output channels includes a full 12-band equalizer
eliminating the need for additional outboard processors. Five
selectable modes of audio equalization are available per output
channel, providing up to 12 bands of fully parametric EQ or varying
combinations of parametric and graphic EQ including a filter set
optimized for speech applications.
Five parametric EQ presets and ten graphic EQ "trim presets" may be
stored onboard the C2VEQ-4, allowing for save and recall of different
EQ curves to account for changing room acoustics, audio material, or
listener preference.
The C2VEQ-4 installs in any Y-Bus expansion slot of a 2-Series control
system. The C2VEQ-4 is also available as the C2N-VEQ4 Cresnet module.
