Above: Rear Panel of Tesira Amplifier 8175R (top) and 4300R CV (bottom)
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. The Tesira AMP-8175R, AMP-4350R and AMP-
4300R CV Current draw is 3 – 2.2 Amps. The Tesira AMP-4175R Current draw is 2 – 2 Amps.
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 distri butor
