VOCIA AMBIENT NOISE COMPENSATION 1 (ANC-1)

The ANC-1 allows the Vocia® system to adjust output levels automatically in response to changes in ambient noise levels. The ANC-1 is

a networked device for use with Biamp’s Vocia Amplier (VA-8600). It accepts two ambient noise inputs at microphone or line level. Most
high-quality dynamic and condenser microphones can be used in conjunction with the ANC-1. Input gain for each of the two inputs is user
congurable via the Vocia software interface. The ANC-1 processes the ambient noise information using Biamp’s adaptive ambient noise

compensation algorithm and sends data to the VA-8600 to change the output level accordingly. The Vocia software interface permits

comprehensive adjustment of ANC parameters. The ANC-1 utilizes IEEE compliant Power over Ethernet (PoE) technology.

ANC-1 SETUP AND USE

Setup and Use

The Vocia software provides an intuitive interface for conguration of the ANC-1. The information supplied by this manual relates to physical

connections and assignment. For more details on setup of the ANC-1 operational parameters please consult the Vocia Help File.

Device ID

The rotary ID switches are located on the ANC-1 and give the unit a unique Device ID. The switches are in hexadecimal format. All
ANC-1 units must have a unique Device ID to function within a Vocia Paging World (i.e., it is not possible to have two ANC-1 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) at 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 ANC-1 is a CobraNet device. All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes
dynamic use of available bundles in CobraNet. Vocia devices are currently not interoperable with non-Vocia devices.

Network Connection

The ANC-1 has one RJ45 connector that should be wired to standard copper Ethernet cabling to interface the ANC-1 to a Vocia system via a
PoE-compliant network switch. The RJ45 connector two LEDs that indicate Ethernet link and network activity (see table below).

This connection carries control data, power, and digital audio over a single Ethernet cable. PoE-enabled network switches or PoE
midspan adapters must be used to power the ANC-1. These must be 802.3af compliant. 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.

Ambient Noise Input Connections

Two plug-in barrier-strip connectors on the ANC-1 connect the ambient sensing sources to the device. One or two microphones or line-level
sources may be connected (gain adjusted accordingly in the Vocia software interface). Both connections may provide phantom power,

switchable from software (default: off). Multiple microphones may be mixed before connecting to the ANC-1.

Installation

The ANC-1 can be mounted on a wall using screws through the case anges (#6 or 6mm dia. X 4) or two screws in the keyholes on the
rear (#8 or 4.5mm dia., max 9mm dia. head).

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.
