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-specic conguration 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-congurable local audio signal processing, including gain, lters, and compressor/limiter

• Rotary switches for unit identication

• 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 conguration, 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 congured correctly.

3. Solid green: The unit is operational, has been congured and is receiving PoE.

2. Signal LEDs

Four LEDs located in the center of the front panel act as audio signal identiers 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
