A460H - Rear Panel Overview
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.
Amplifier Output Connections
Speaker Connection
To minimize power loss, use a speaker cable of appropriate gauge for the load impedance. For long
speaker cables, choose a low capacitance cable to minimize high frequency loss. Use the supplied plug-
in barrier strip connectors to connect loudspeaker outputs. If stranded speaker wire is used, be sure to
incorporate all strands into the connector, as stray strands can short to the adjacent terminal or chassis.
Do not leave excessive bare wire outside the terminals, as this can lead to shorts. Use of the supplied
cable restraints is required to secure the cable in the connector. To facilitate parallel wiring, each
connector allows for the connection of two conductors to each amplifier channel.

CAUTION
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
for all service requirements.
CAUTION
All speaker wiring connections should be made by qualified personnel and with the amplifier power removed. The 100V output
requires Class 3 wiring. Please refer to a qualified electrician or other qualified person according to local codes.
