ACCESSORY
Voltage Control Box
Voltage Control Box is a natural extension of Audia® and Nexia® products. It provides four inputs for
analog potentiometers plus four logic input/output connections, as a programmable control interface.
Voltage Control Box allows creation of custom control panels, with completely programmable functions.
Potentiometers may be assigned to control various system levels. Logic connections may be assigned
individually as either inputs or outputs, for switch control of internal functions such as preset selection
or for triggering external circuits such as status indicators. The Voltage Control Box is connected to a
system on a 5-wire daisy-chain, eliminating the need for local power sources. This connection also
provides the serial communication to the Audia or Nexia system. Multiple Voltage Control Boxes, as
well as other Audia/Nexia controls, can be connected on a single bus, over a large physical distance.
FEATURES
four analog potentiometer inputs control system levels
four logic connections - any combination of inputs/outputs
logic inputs control presets, mutes, ducking, combining, etc.
logic outputs trigger external indicators, speaker relays, etc.
control functions assigned within system software design
control functions can be made to change along with presets
various Audia/Nexia controls allowed on same system bus
1000' cable length per Audia/Nexia device control bus
convenient key-hole mounting (local power not required)
RoHS compliance
covered by Biamp Systems' five-year warranty
ARCHITECTS & ENGINEERS SPECIFICATION
The control interface shall provide four analog potentiometer inputs, plus four logic connections programmable in any combination
of inputs/outputs. The control interface shall include key-hole mounting, and shall require no local power source. The control
interface shall provide programmable remote control of internal functions and external circuitry for Biamp's Audia
products. The control interface shall be compliant with EU Directive 2002/95/EC, the RoHS directive. Warranty coverage shall be
five years. The control interface shall be a BIAMP Voltage Control Box.
