Device ID switches
The rotary ID switches are located on the back of the amplifier and give the unit a unique Device ID. The switches are in
hexadecimal format. All Vocia units of the same type must have a unique Device ID to function properly within a Vocia Paging
World (for instance, it is not possible to have two Vocia devices of the same type with the same Device ID of hex 07). Note that
VA-4030 and VA-4030e units represent one device type, while VA-2060 and VA-2060e units represent another device type.
As an example, to assign a Device ID of hex 07, leave the MSB switch on 0 and turn the LSB switch to 7. To create an ID of hex B7, turn
the MSB switch to B and turn the LSB switch to 7. Device ID switches should be set using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat
blade screwdriver. More information on setting IDs and the hexadecimal numbering scheme used can be found in the Vocia Software
Help File.
Analog Audio Inputs with Phantom Power Option
For the VA-2060e and VA-4030e, each amplifier channel has analog inputs that allow a local balanced
microphone or line level background source to be delivered to the amplifier channel associated with
that input. Two such inputs are available on the VA-2060e amplifier and four on the VA-4030e. Input
sensitivity and 48V phantom power on/off state may be determined in the Vocia software. Because a
local input may only be delivered to the channel associated with that input, if a local background source is required on two or more chan-
nels the source must be wired in parallel to each of the inputs. An exception is that if two or more channels of an amplifier are configured
in software as a group or multi-way, the lowest local input channel number will be presented to all channels. For instance, if a VA-4030 is
deployed with channels 2, 3 and 4 configured as a group or 3-way multi-way, local input 2 will be presented to outputs 2, 3 and 4.
Page Active Relay
Page Active Relays (PAR) are available on all amplifiers. Via the Page Active Relay connectors, one Form C (single pole, changeover)
relay is presented per channel for the VA-4030 and VA-4030e. Similarly, two such relays per channel are presented for the VA-2060 and
VA-2060e (relays operate in tandem). Each PAR connector is a six-way 3.5mm pluggable screw terminal block. The PAR connections are
labeled as follows:
• C: Relay Common
• NC: Normally Closed
• NO: Normally Open
