Crestron C2VEQ-4 

Volume/Equalizer Control Expansion Card

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. 

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.  

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.
