4 Setup
4.6 Wire Your System
Before you wire your system, you must be familiar with
the capabilities of the input routing.
The DriveCore amplifier can be configured in two ways:
1. The input for a channel goes out the same channel.
This option is the standard configuration.

2. The input for a channel can be routed to the next
channel, overriding the wired input signal for that
channel. This method simplifies input wiring and
minimizes use of y-cables.

Input routing is configured using the dip switches on the
back of the amplifier. See Section 11 Input Routing
for information on configuring switches.
Note: ComTech DriveCore amplifiers can NOT be bridged.

4.7 Connect to AC Mains
Connect your amplifier to the AC mains power source
(power outlet) with the supplied AC power cordset. First,
connect the IEC end of the cordset to the IEC connector
on the amplifier; then, plug the other end of the cord set
to the AC mains.
WARNING: The third prong of this connector
(ground) is an important safety feature. Do not
attempt to disable this ground connection by
using an adapter or other methods.
Amplifiers don't create energy. The AC mains voltage and
current must be sufficient to deliver the power you
expect. If the AC line voltage varies out of an acceptable
range, the amplifier's power supply turns off and the blue
Power LED flashes. The amplifier will turn back on when
the AC line voltage returns to safe operating levels.
Figure 4.7.1 provides voltage limits for all amplifier AC
voltage configurations. Also, the amplifier must be run
within the specified mains frequency requirements
(indicated on the amplifier's back panel label). If you are
unsure of the output voltage of your AC mains, please
consult your electrician.
