®
system. The VO-4
accepts four channels of digital audio input via CobraNet® and provides four line-level analog audio outputs. The VO-4 features embedded
DSP and on-board memory to process and store all device-specic conguration information locally and includes comprehensive, xed-chain,
digital-signal processing. As part of the Vocia system, the VO-4 meets paging requirements for facilities of all sizes.
FEATURES
• Converts digital to analog
• Four removable terminal block connectors for line-level outputs
• Four control inputs and four control outputs
• Software-congurable local audio signal processing, including gain, lters, and compressor/limiter
• Rotary switches for unit identication
• Power Over Ethernet (PoE)
• CobraNet audio/control on single cable
• Status LEDs to indicate signal and clip
• CE marked and RoHS compliant
• Covered by BIAMP Systems’ warranty

VO-4 FRONT PANEL
Setup and Use
The Vocia software provides an intuitive interface for conguration, DSP equalization, and programming of the VO-4. The information supplied
by this manual relates to physical connections and assignment. For more details on software setup, please consult the Vocia Help File.

1. Power Indicator LED
On the left of the front panel, the VO-4 has a single LED that indicates power and connectivity status:
1. Not illuminated: The device is not powered.
2. Flashing green: The unit is receiving power but not data, or the unit has not been congured correctly.
3. Solid green: The unit is operational, has been congured and is receiving PoE.
2. Signal LEDs
Four LEDs located in the center of the front panel act as audio signal identiers for the four input channels and are useful for setting optimum signal
levels. Each LED has four states. Please see the table below for the signal mapping to each of the LEDs. Detailed metering of current output levels

Network Connection
The VO-4 has one RJ45 connector located on the rear panel that utilizes standard Ethernet cabling to interface the VO-4 to the Vocia system
via a managed network switch. The RJ45 connector provides two LEDs that indicate Ethernet link and network activity (see table below).
Left LED Right LED Description
None None No power or data connectivity. Please check the PoE network connection.
Green None Link established.

CobraNet fault. Check cabling and conguration for errors.
Device ID
The rotary ID switches are located on the back of the VO-4 and give the unit a unique Device ID. The switches are in hexadecimal
format. All VO-4 units must have a unique Device ID to function properly within a Vocia Paging World (i.e., it is not possible to have
two VO-4 units with the same Device ID of hex 07). To assign a Device ID of hex 07, turn the LSB switch to 7 and leave the MSB
switch on 0. To create an ID of hex B7, turn the LSB switch to 7 and turn the MSB switch to B. Device ID switches should be set using
a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver. More information on setting IDs and the hexadecimal numbering
scheme used in Vocia can be found in the Vocia Help File.
Please note: Changes made to the Device ID while connected to the network require a power cycle in order to take effect.
CobraNet
The VO-4 is a CobraNet device. All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia devices
are not interoperable with non-Vocia devices.
6
VO-4 REAR PANEL CONTROLS
This connection carries control data, power, and digital audio over CobraNet. The maximum distance between any unit and an Ethernet
switch is 328 feet (100 meters) when using copper cabling. Additional Ethernet switches and/or ber-optic cable can be used to further
extend distances between units on a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions)
within a network.
If other network trafc shares an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs.
All Ethernet wiring is to be done using shielded CAT5, CAT5e, CAT6, or CAT7 cable.

Control Outputs
The Control Outputs, labeled 1 through 4, are isolated, voltage-free, software-congurable relay outputs.
The individual pins are labeled as follows:
1. (C): the common/ground pin
2. (NC): normally closed (connected to C when relay is not energized)
3. (NO): normally open (connected to C when relay is energized)
Control Inputs
The Control Inputs are labeled as follows:
1. ( ): logic common/ground input pin
2. (1–4): individual logic inputs
3. (10V): 10V reference voltage (when used as a switch input, a switch must be connected
between the input and logic common terminal)
Audio Inputs
Four plug-in barrier strip connectors provide analog audio signal output. The Vocia software enables a nominal output level of +4 dBu, 0 dBu,
or -10 dBu to support a wide range of connection devices. All plug-in barrier strip connectors should be wired from left to right as follows:
1. (+) High
2. (–) Low
3. ( ) Ground
Ground Screw
This screw provides a connection point to ground the chassis of the VO-4. The power supply to the VO-4 is sourced from PoE, which may
have no connection to ground. The chassis of the VO-4 should be connected to a safety ground (main power supply ground) using the
Ground Screw
8
VO-4 INSTALLATION
Installation
The VO-4 requires one 1.75 inches (44.45mm) high and 19 inches wide rack space with 10 inches (254mm) depth. Mounting the unit using
four screws with washers will prevent marring of the front panel. PVC or nylon washers are appropriate.
Please install the unit away from heat sources, such as vents and radiators, and in rooms with adequate ventilation. Ensure that air can
circulate freely behind, beside, and above the unit. Do not exceed the maximum ambient operating temperature of 113 degrees F (45°C).
Be aware of conditions in an enclosed rack that may cause the temperature to exceed ambient room conditions.
