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 Amplier (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
congurable 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.
FEATURES
• Automatic, adaptive volume adjustment based on ambient noise sensing and processing
• 48V phantom power
• Wall mountable
• CobraNet audio/control with dynamic use of available bundles, plus power on a single cable
• Power and data over a single Ethernet cable
• Status LEDs
• Sturdy component housing
• CE marked and RoHS compliant
• Covered by BIAMP Systems’ warranty

ANC-1 SETUP AND USE
Setup and Use
The Vocia software provides an intuitive interface for conguration 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 devices
are not interoperable with non-Vocia devices.
Network Connection
The ANC-1 has one RJ45 connector that should be wired to CAT5, CAT5e, CAT6, or CAT7 cabling to interface the ANC-1 to a Vocia system
via a PoE-compliant 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.

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 100 meters (328 feet) 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.

ANC-1 INSTALLATION
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.
