Conventions
All numbered audio, relay and power connectors on the rear panel of the amplifier are configured with the lowest output or input on the
right of the connector as viewed from the rear of the unit.
AC Power Socket
Provides for connection of the appropriate power cord. Each amplifier uses a switch mode power supply that has an operating voltage
of 100-240V at 50/60 Hz.
Auxiliary Power: Only available with VA-2060e and VA-4030e amplifiers.
This connection allows dual 24V DC power inputs to be used. Dual 24V DC supply capability allows the amplifier to
meet standards that call for redundant power supplies. The DC supply must be wired into both power supply inputs,
either from redundant supplies or from a single supply wired in parallel to the two inputs. If 24V is not supplied to both inputs, a loss-of-
supply fault will be reported. If a VA-4030e or VA-2060e amplifier is required to operate without a 24V supply, the Auxiliary supply fault
monitoring must be disabled in Vocia software. A loss of supply fault is indicated via the Vocia software and by a blinking yellow Amp Fault
indicator on the front panel of the affected device. The power supplies used for the amplifier must meet the voltage range and power re-
quirements detailed in the specifications table below. Local standards, norms or codes may require the use of certified power supplies and
may require observance of minimum on-battery running times both for standby and maximum power conditions. Note that dual redundant
power supplies must each independently meet the total power requirements of the amplifier.
The pluggable terminal blocks provided will accommodate wire sizes from 12-18 AWG. External over-current protection must be provided,
according to the current carrying capacity of the connecting wires, and in no case greater than 30 Amps. Do not ground or connect to chassis
either the positive or negative Auxiliary Power connections. The Auxiliary power must be floating with respect to ground.
Network Connections
The amplifier is a CobraNet device. A Primary and Secondary CobraNet connection is provided for this. All
CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes dynamic use
of available bundles in CobraNet. A 100Base-T Ethernet switch (not repeater hub) is required when networking
multiple units. CobraNet utilizes standard CAT5, CAT5e, CAT6 or CAT7 cabling, which has a specified maximum length of 328 feet (100
meters). Additional Ethernet switches, or switches that provide fiber-optic interface, can be used to extend the physical distance between
units within a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within a network. The
CobraNet network connection is configured with the primary connector on the left and the secondary (redundant) connector on the right.
The primary and secondary CobraNet ports are provided to facilitate connection redundancy. Each connector provides two LEDs that
indicate Ethernet link and network activity.
