Crestron C2VEQ-4 Volume/Equalizer Control Expansion Card

Volume/Equalizer Control

Expansion Card: C2VEQ-4

Purpose

The purpose of this addendum is to provide additional specification detail and related

changes not supplied with the original C2VEQ-4 Operations & Installation Guide

(Doc. 6136). Specifically, this addendum corrects:

• Description of parametric/graphic filters that appeared on page 2.

• Specification table that appeared on page 3.

Correction for Description of Parametric/Graphic Filters

The original description of the parametric/graphic filters did not mention that the

filters are programmable using either Crestron’s Digital Audio Tools software or

SIMPL Windows, and that the value ranges for certain parameters are different

between the two programs. The following text replaces the original material; the blue

text is original information included here to help locate the added/corrected text,

shown in bold:

Each of the four channels has a twelve-filter parametric equalizer that permits you to

correct for acoustical distortions in the listening area or in the speakers themselves,

and/or to establish preset values that enhance the sound conditions for favorite music

or recording media.

Equalization controls are programmable using Crestron’s Digital Audio Tools

(DAT) software or SIMPL Windows (SIMPL). Refer to “Programming

Software” on page 7 for details.

The 12 filters are identical in function. Each delivers up to 12 dB of boost or cut

when using DAT software; from -36 dB to +24 dB in a SIMPL program. Each

filter also has an adjustable bandwidth control (from 0.02 octaves to 2 octaves

using DAT software; from 0.02 octaves to 3.50 octaves using SIMPL), and a

center frequency control range (from 25 Hz to 19.9 kHz from DAT; from 5 Hz

to 24 kHz using SIMPL). Use each filter anywhere in the audio spectrum, not just

pre-selected ranges as typically found on graphic equalizers. In addition, you can

select from among five filter types (low pass, high pass, EQ filter, bass shelf, and

treble shelf) or select no filter.
