type plug has two blades and a third
grounding prong.
The third prong is provided for your
safety. If the provided plug does not
fit into your outlet, consult an
electrician for replacement of the
obsolete outlet.
10) Protect the power cord from being
walked on or pinched particularly at plugs,
convenience receptacles, and the point
where they exit from the product.
11) Only use attachments/accessories
specified by the manufacturer.
12) Use only with equipment rack, cart,
stand or table designed to provide adequate
mechanical strength, heat dissipation and
securement to the building structure.
When a cart is used, use
caution when moving the cart
and product combination to
avoid injury from tip-over.
13) Unplug this product during lightning
storms or when unused for long periods of
time.
14) Refer all servicing to qualified service
personnel. Servicing is required when the
product has been damaged in any way, such
as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen
into the product, the product has been
exposed to rain or moisture, does not
operate normally, or has been dropped.
WARNING - To reduce the risk of fire or electric shock, do not expose this product to rain or
moisture.
WARNING - This product employs Safety Grounding and must be connected to a MAINS
socket that is properly grounded to provide a protective earthing connection.
Disconnect Device - The MAINS plug is used to disconnect MAINS power and must be
installed near the equipment and remain readily accessible.
Explanation of safety related symbols - Product labeling and the operation manual may
use the internationally recognized symbols defined below to note safety messages.
Lightning Bolt: Hazardous Live voltages present when this unit is in operation. Do
not touch terminals marked with this symbol while the unit is connected to live power.
Exclamation Point: Replace components (i.e. fuses) only with the values specified by

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.
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 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 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).
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.

ANC-1 SETUP AND USE
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.
