Input Connector
3.3 Connecting the Input Signal
Both an unbalanced Input BNC jack and a bal-
anced Input “WECO” terminal block connector
(mating WECO connector provided) are available
on the amplifier back I/O panel for signal input.
Connect your input signal source to the unbal-
anced or balanced input connector as shown in
Figure 3.3.
Use cables that are high quality and
shielded to minimize noise and to guard against
possible feedback.

Input Connector Enable/Disable
enabled. When the DIP switches are placed in the
DOWN position, the input connectors are disabled.
See
Figure 3.4
for DIP switch locations.
3.4 Other DIP Switch Settings
Other DIP switches located on the amplifier mod-
ule labeled “Master” can be used to enable fea-
tures or configure the amplifier for special applica-
tions. See the
Advanced Configuration
section of
this manual for more informaiton. Before operating
the amplifier, check to make sure all DIP switches
are set as intended. See
Figure 5.1
for the factory
default setting for all DIP switches.
3.5 Monitor and Sense Ports
The amplifier provides three additional ports on the
back I/O panel:
•
Current Monitor (BNC connector)
•
Voltage Monitor (BNC connector)
•
Remote Sense Port (2-pin terminal block con-
nector.
See the
Applications
section of this manual for
information on using these ports
3.6 Connecting the AC Supply
Always operate the amplifier from the proper AC
mains. The 8500 series amplifier requires three-
phase, 50-60 Hz, 208 VAC (or optional 400 VAC)
with no more than 10% variance above or below
the line voltage. The amplifier will not operate
properly outside these limits.
DIP switch #1, located on the back panel of the
Master amplifier module (uppermost module in the
amplifier) can be used to enable/disable the unbal-
anced input connector, and DIP switch #2 can be
used to enable/disable the balanced input connec-
tor.
When these two DIP switches are placed in the UP
position (factory default), the input connectors are
