Cresnet 4-Channel Digital Volume

Control: C2N-VEQ4

Introduction

Features and Functions

The Crestron®C2N-VEQ4 Cresnet®4-Channel Digital Volume Control module is a

digitally controlled 4-channel audio processor that incorporates volume, tone, mixer

and equalization capabilities. Each channel has independent settings for volume,

treble, bass, mute, and mixer controls plus a 12-band parametric equalizer.

Volume/tone controls are compatible with both X-Generation and 2-Series control

systems. Equalization and mixer controls are only accessible from 2-Series

processors.

Refer to the simplified block diagram provided on the next page.

Functional Summary

Volume, bass, and treble ramp times, scaling, preset levels, and volume muting may

be specified on a per-channel basis. All of these aspects are software controllable.

Volume, bass, and treble control may be sent to more than one channel via software

to support stereo applications.

• Four balanced/unbalanced audio I/O channels

• 24-bit 96KHz A/D and D/A converters with dual DSPs provide

improved audio quality

• Independent settings for volume, treble, bass, and mute per channel

• 4 x 4 matrix mixer controls set the percentage of each input desired at

each output (any input to any output)

• Five modes of audio equalization per channel

- a ten-band graphic equalizer and two-band parametric equalizer

- a five-band graphic equalizer and seven-band parametric equalizer

- a speech-optimized five-band graphic equalizer and seven-band

parametric equalizer

- a three-band graphic equalizer and nine-band parametric equalizer

- a full twelve-band parametric equalizer

• Touch settable ID capable

Input and output connections are completely independent of each other. Therefore, it

is possible to have a balanced input paired with an unbalanced output and vice-versa.

The treble and bass controls are independent from volume and are individually

controlled for each channel. Each channel includes a muting relay with 100 dB

attenuation. When the signal driving Mute1 goes high, the muting circuit is activated

providing 100 dB attenuation from any preset volume level. Likewise, channels “2,”

“3,”and “4” drive Mute2, Mute3, and Mute4, respectively. When the muting signal

goes low, the muting circuit is deactivated and the volume and tone return to their

original preset levels.

NOTE: MuteAll is an override. All channels are muted when this signal is high.

When it is low, the channels follow the state of Mute1, Mute2, Mute3 and Mute4.

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 Media Tools (DMT)

software or SIMPL Windows (SIMPL). Refer to “Programming Software” on page

13 for details.

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

when using DMT 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 DMT

software; from 0.02 octaves to 3.5 octaves using SIMPL), and a center frequency

control range (from 25 Hz to 19.9 kHz from DMT; 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, peaking EQ (equalization)/notch, bass shelf, and

treble shelf) or select no filter.

Each channel is equipped with protective relays that turn ON only after safe

conditions are sustained by the electronic circuitry. This feature protects the output

from “pops” caused by accidental power-down/up conditions to the C2N-VEQ4.

If the C2N-VEQ4 is under program control and the power is cycled to the

C2N-VEQ4, it renews the volume, bass, and treble levels to the current program

settings. The mute status (per channel and the mute-all) is also restored.

Physical Description

The C2N-VEQ4, shown below, is housed in a black enclosure with labeling on the

front and rear panels. Six LEDs on the front of the unit indicate the unit’s status. All

connections are made on the back of the unit. There are four rubber feet on the base

of the unit for stability and to prevent slippage.

balanced/unbalanced output (OUT) ports to an amplifier. Each channel includes a

muting relay with 100 dB attenuation.

G (Chassis Ground)

Use this chassis screw to ground the unit to the amplifier and audio source common

grounds.

NET

This 4-pin network connector is used to connect the C2N-VEQ4 module to the

Cresnet system. Data and power for the C2N-VEQ4 are provided via the connection.

Refer to “Network Wiring” on page 7.

C2N-VEQ4 Indicators

There are six LED indicators located on the front panel of the C2N-VEQ4. Refer to

the illustration below and descriptions that follow.

C2N-VEQ4 Indicators

PWR (Power)

This green LED illuminates when power is supplied to the C2N-VEQ4.

NET

This yellow LED illuminates when communication between the control system and

the C2N-VEQ4 is established (the unit is polled on the network). Illumination

indicates that the program currently loaded has a network device defined at the same

ID as the C2N-VEQ4. The LED flashes when communication with the processor

occurs.

ACTIVITY (1 – 4)

These red LEDs illuminate only when there is activity on any of the four channels.

Activity includes any change in volume, tone (bass, treble), mixer, or equalization

parameters. Once the command is completed, the related LED(s) go out.

SETUP LED and Pushbutton

The C2N-VEQ4 is TSID ready. The SETUP pushbutton and its associated LED are

located on the rear panel and are used for setup of the unit’s network ID during the

initial configuration of a Cresnet®system or when the device is being added/replaced.

Refer to “Method B (Touch Settable IDs)” on page 9 for detailed information.
