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 chassis 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 range of 100-240V at 50/60 Hz.
Do not remove or defeat the ground prong on the power cord, as this will constitute a shock hazard. Equipment should be
connected to a mains socket outlet with a protective earthing connection. This plug is the main disconnecting device and should
remain readily operable. There are no user interchangeable parts. Please contact Biamp Technical Support or your local distributor
Auxiliary Power
The VA-8150CV and VA-4300CV support 48V DC Auxiliary power connections.
This Connection allows dual DC power inputs to be used. Dual DC supply capability allows the amplifier
to meet standards that call for redundant power supplies. If an amplifier is required to operate without a
DC 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 amber 'Amp Fault' indicator on the front panel of the
affected device. The power supplies used for the amplifier must meet the voltage range and current
requirements detailed in the specifications table. 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.
Dual redundant Auxiliary power supplies must each independently meet the total power requirements of the amplifier
The pluggable terminal blocks provided will accommodate a wire gauge size of 8 AWG
maximum. 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.
Due to potential energy hazard, connections to the Auxiliary Power DC inputs must be made by a qualified electrician or other
