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.

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.

Industry Compliance
As of the date of manufacture, the C2N-VEQ4 has been tested and found to comply
with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling.
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Setup
Network Wiring
CAUTION: In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire, and only Crestron Certified Wire,
should be used. Failure to do so may incur additional charges if support is required to
identify performance deficiencies as a result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system
(http://www.crestron.com/calculators).
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Crestron website.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the Cresnet power usage of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the Cresnet power
usage of each unit to be daisy-chained must be added together to determine the
Cresnet power usage of the entire chain. If the unit is a home-run from a Crestron
system power supply network port, the Cresnet power usage of that unit is the Cresnet
power usage of the entire run. The length of the run in feet and the Cresnet power
usage of the run should be used in the following resistance equation to calculate the
value on the right side of the equation.
Resistance Equation
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
R < L x P
40,000 Where:

Cresnet 4-Channel Digital Volume Control Crestron C2N-VEQ4
8 •Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 Operations Guide - DOC. 6135A
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the following table.
Wire Gauge Values
RESISTANCE WIRE GAUGE
4 16
6 18
10 20
15 22
13 Doubled CAT 5
8.7 Tripled CAT 5
NOTE: All Cresnet wiring must consist of two twisted pairs. One twisted pair is the
+24V conductor and the GND conductor, and the other twisted pair is the Y
conductor and the Z conductor.
NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.
Identity Code
Every equipment and user interface within the network requires a unique identity
code (Net ID). These codes are recognized by a two-digit hexadecimal number from
03 to FE. The Net ID of each unit must match an ID code specified in the SIMPL
Windows program. Refer to “Setting the Net ID in Device Settings” on page 15 for
details of the SIMPL Windows procedure.
Refer to the note on page 26 for
a definition of Viewport.
The Net ID of the C2N-VEQ4 has been factory set to 12. The Net IDs of multiple
C2N-VEQ4s in the same system must be unique. Net IDs are changed from a
personal computer (PC) via the Crestron Viewport.
NOTE: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” on page 26. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
There are two different methods—Method A or Method B—for setting the
C2N-VEQ4 Net IDs:
Method A (Cresnet address-settable ID), described on page 9, applies to
C2N-VEQ4s in a Cresnet system with a CNX control system or with a 2-Series
control system upgrade file (CUZ) version prior to 3.008, but can be used with later
versions of firmware and requires that a single unit be the only network device
connected to the control system.
Method B (Touch Settable IDs), which begins on page 9, applies to C2N-VEQ4s in a
Cresnet system with 2-Series control system upgrade file (CUZ) version 3.029 or
later. These upgrades enable Touch Settable ID (TSID) functionality, which makes it

Crestron C2N-VEQ4 Cresnet 4-Channel Digital Volume Control
Operations Guide - DOC. 6135A Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 •9
possible for the control system to recognize a network device via its serial number,
which is stored in the device’s memory. This method does not require that any
devices be disconnected from the network; Net IDs may be set with the entire Cresnet
system intact. This method requires the use of the Crestron Viewport version 3.35 or
later.
Use the appropriate method to set the C2N-VEQ4 Net ID.
Method A (Cresnet address-settable ID)
1. Ensure that the C2N-VEQ4 is the only device connected to the control
system.
2. Open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID. The
software checks the baud rate and then opens the "Set Network ID"
window.
4. In the "Set Network ID" window, select the C2N-VEQ4 from the
Current Network Devices text window.
5. Select the new Net ID for the C2N-VEQ4 from the Choose the new
network ID for the selected device (Hex): text box.
6. Click Set ID to initiate the change. This will display the "ID command
has been sent" window.
7. In the "Command Complete" window, click OK.
8. In the Current Network Devices text window, verify the new Net ID
code.
9. In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting Diagnostic | Report
Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each C2N-VEQ4 to be added to the system.
Method B (Touch Settable IDs)
Before using this method, you should have a list of all current network devices and
their Net IDs, to avoid assigning duplicate IDs.
Set Net ID by TSID
These procedures are for TSID-enabled network devices during the initial
configuration of a Cresnet system or when such devices are being added/replaced.
1. Ensure that all C2N-VEQ4s are connected to the control system.
2. Open the Crestron Viewport version 3.35 or later.
3. From the Viewport menu, select Functions | Assign Cresnet ID by
Serial Number. The “Set Net ID by TSID” window appears. The
window is first displayed with the data fields empty.

Cresnet 4-Channel Digital Volume Control Crestron C2N-VEQ4
10 •Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 Operations Guide - DOC. 6135A
“Set Net ID by TSID” Window
4. Click on the Search for Touch Settable Devices button. The system
searches the network and lists all TSID-enabled devices found. The list
is similar to the report produced by pressing F4 (Report Network
Devices); the first eight digits of each line constitute the TSID number
(hexadecimal form of the serial number).
5. As you enter either the serial number or TSID number of the device that
requires a change, the corresponding TSID or serial number
automatically appears in its appropriate field, and the list scrolls to and
highlights the device listing. The listing should show the device’s
current Cresnet ID.
6. Enter the Cresnet ID that the device should be set to and click OK. The
number you enter should appear on the list.
CAUTION: This function does not prevent you from setting duplicate IDs. Be sure
to check current assignments before entering the desired Cresnet ID number.
Serial Number to TSID Conversion
This utility is useful in a case where there are multiple devices of the same type on a
network, you need to locate a particular one, you know the TSID but not the serial
number, and your site installation list is based on device serial numbers. In this (or the
reverse) situation, do the following:
1. Open the Crestron Viewport.
2. From the Viewport menu, select Functions | Serial Number ÅÆ
TSID Conversion Tool. The “Serial Number ÅÆTSID Conversion
Tool” window is displayed.

First-time users will need to establish a user account.
You can create a program that allows you to include the C2N-VEQ4 in a Crestron
control system using the Crestron programming tools Crestron SystemBuilder™ and
SIMPL Windows. These tools are intended for users with different levels of
programming knowledge. The flexibility of each tool is proportional to the degree of
programming expertise (i.e., the more flexible, the more a programmer needs to know
and account for). Of course, one can initiate programming using the easiest method
(SystemBuilder) and use advanced techniques that are available from SIMPL
Windows to customize the job.
Earliest Version Software Requirements for the PC
NOTE: Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the Crestron
website.
• (Optional) SystemBuilder version 2.0 or later. Requires SIMPL Windows
and Crestron Engraver. Requires SystemBuilder templates 1.10 or later.
• SIMPL Windows version 2.05.22 or later.
Requires SIMPL+ Cross Compiler version 1.1.
• Crestron Database version 16.4.4 or later. Required by SIMPL Windows.
• Crestron Engraver version 2.3.3.2 (required if using SystemBuilder).
• Digital Media Tools version 1.01.01 or later, with configuration template for
C2N-VEQ4.
The Digital Media Tools software is the preferred method to adjust equalization. In
fact, if you want to use a graphic equalizer, you MUST use Digital Media Tools,
because this is where the default graphic equalizer characteristics are set up. Refer to
page 16 for more details on using Digital Media Tools.
Programming with the Crestron SystemBuilder
The easiest method of
p
rogramming, but does not
offer as much flexibility as
SIMPL Windows.
The Crestron SystemBuilder offers automatic programming for such residential and
commercial applications as audio distribution, home theater, video conferencing,
and lighting. The interface of this tool guides you through a few basic steps for
designating rooms and specifying the control system, touchpanels, devices, and
functionality. The Crestron SystemBuilder then programs the system, including all
touchpanel projects and control system logic.
Crestron SystemBuilder is fully integrated with Crestron's suite of software
development tools, including SIMPL Windows, Crestron VisionTools®Pro-e
(VT Pro-e), Crestron Engraver, Crestron Database, User IR Database, and User

.csz projectname.csz (compiled file for CNX generation with SIMPL+)
.ush projectname.ush (compiled file for CNX generation with SIMPL+
header file)
.usp projectname.usp (source code module for SIMPL+)
SIMPL Windows is Crestron's software for programming Crestron control systems. It
provides a well-designed graphical environment with a number of workspaces (i.e.,
windows) in which a programmer can select, configure, program, test, and monitor a
Crestron control system. SIMPL Windows offers drag and drop functionality in a
familiar Windows®environment.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.
NOTE: In the following description, the PRO2 control system is used.
NOTE: 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.
This section describes a sample SIMPL Windows program that includes a
C2N-VEQ4.
Configuration Manager is where programmers “build” a Crestron control system by
selecting hardware from the Device Library. In Configuration Manager, drag the
PRO2 from the Control Systems folder of the Device Library and drop it in the upper
pane of the System Views. The PRO2 with its associated communication ports is
displayed in the System Views upper pane.
PRO2 System View
The System Views lower pane displays the PRO2 system tree (refer to graphic on the

Control Modules | Cresnet Audio Modules folder of the Device Library and drop it in
System Views. The PRO2 system tree displays the C2N-VEQ4 in Slot 9, with a
default Net ID of 12 as shown in the following illustration.
NOTE: The first C2N-VEQ4 in a system is preset with a Net ID of 12 when its
symbol is dragged into the upper pane of System Views. Additional units are assigned
different Net ID numbers as they are added.

NOTE: SIMPL Windows automatically changes Net ID values of a device added to a
program if a duplicate device or a device with the same default Net ID already exists
in the program. Always ensure that the hardware and software settings of the Net ID
match. For Net ID hardware setting details, refer to “Identity Code” on page 8.
C2N-VEQ4 Symbols in Programming Manager
Programming Manager is where programmers “program” a Creston control system by
assigning signals to symbols. Due to the extensive functionality of the C2N-VEQ4, a
single symbol in SIMPL Windows would be too complex. Instead, the C2N-VEQ4 is
broken up into slots. In Program Manager, expand the C2N-VEQ4 to view the
individual slots, and then drag the desired symbol to Detail View. The slots and
corresponding symbols are described beginning on the next page.
NOTE: The volume, bass, treble, and mixer program settings are stored in the
SIMPL program; the C2N-VEQ4 assumes a zero value for each of them. The EQ trim
and filter control settings are stored in the unit itself, and can be activated using
“recall” functions.
The full parametric equalization controls built into the C2N-VEQ4 provide graphic
and parametric equalization, programmable using Crestron's Digital Media Tools
software or SIMPL Windows. The Digital Media Tools (DMT) software is free and
available from the download section of the Crestron website.
Almost all users will use the Digital Media Tools and not the SIMPL Windows
symbol to adjust equalization because of the program’s simplicity, speed, and ease of
operation. From the point of view of the symbols, everything is parametric
equalization; graphic equalizers are just parametric equalizers with specific default
frequencies, Q (bandwidth), and type. If you want to use a graphic equalizer, you
MUST use Digital Media Tools, because this is where the default graphic equalizer
characteristics are set up. Programmers might want to set up sliders from the
TrimBand gains to let the user modify slightly what the programmer has stored.
The C2N-VEQ4 adjustments in Digital Media Tools contain five tabs:
• Room Calibration – for analyzing the room and compensating for any
unwanted effects (such as noise from an HVAC system, reflections from
hard surfaces, and resonance at particular frequencies) so the listener hears
what was intended when the material was recorded.
• Input Settings – for setting the input levels for analog audio sources. Using
this adjustment properly lets you compensate for analog sources with
different input levels to obtain a seamless transition between sources at a
given volume level.
• Graphic EQ – for choosing the number of graphic equalizers, and provides
access to the graphic equalizer sliders
• Parametric EQ – for making parametric equalization adjustments
• Communications – for setting up communications and adjusting the
equalizer in real time.
