4.6 WireYour 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:

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.

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.

1.The input for a channel goes out the same channel. This option is the standard configuration.

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.

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.
