        • 24-bit 96KHz A/D and D/A converters | Dual DSPs
        • 4 balanced/unbalanced line-level I/O channels
        • Fully adjustable 4 x 4 audio matrix mixer

        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.
