Back-Panel Controls & Connectors
4.2
This section provides an overview of Back-Panel
controls and connectors found on the 8500 series
amplifier. Please refer to Figure 4.2 for component
locations.
Unbalanced BNC Input Connector – This input
option provides a standard unbalanced input.
Balanced WECO Input Connector – This input
option provides a balanced input. Mating WECO
connector is provided with the amplifier.
Current Monitor Connector – This unbalanced
BNC port allows for connection to current monitor-
ing equipment. The current monitor output is 1V =
20A.
Voltage Monitor Connector – This unbalanced
BNC port allows for connection to voltage monitor-
ing equipment. The voltage monitor output is 1V =
40V.
Remote Sense Port – This 2-pin terminal block
connector provides a sense line with up to 4V of
correction. The Remote Sense port can be useful
when the voltage at the load must be precise. If
the cables connecting the amplifier and the load
are very long or under-sized, the voltage drop
between the amplifier and load can be corrected
up to 4V.
The benefits of this feature is limited to frequencies
below 10kHz.

using 3/8-inch ring terminals.
Back-Panel Safety Features
4.3
This section provides an overview of Back-Panel
safety features found on the 8500 series amplifier.
Please refer to Figure 4.3 for component loca-
tions.
AC Breakers – This switch controls the power to
the amplifier. Place in the ON position to energize
the amplifier system. Switch to the OFF position to
remove power from the system.
Magnetic Safety Switch – This door-mounted
switch controls the power to the amplifier. When
the amplifier's back access door is opened, power
is removed from the amplifier system. Close the
back access door to energize the amplifier system.
