SPEAKER OUTPUT CONNECTIONS

Speakers are connected using the output barrier strip connectors. Spade lugs, ring tongues or bare wire may be connected to the output barrier strip elements. The barrier strip can accommodate up to two 10-guage wires per terminal. Make sure the amplifier is turned off before you change any output connections or jumpers. Consult the Wire Gauge Chart at the back of this manual to find a suitable wire gauge to minimize losses of power in the speaker cables. Also, make sure that the load impedance is not lower than that rated for the amplifier.

SIGNAL GROUND CONNECTION

Connections at the input connector permit the audio signal ground to be connected or lifted from the chassis ground. When possible, the shield of the signal source connecting cable should connect to the chassis ground. In some cases, however, particularly if an amplifier is being installed in an existing system, this may result in a ground loop. If this happens, connect the shield to the signal ground only. The chassis ground also connects to the AC ground internally. If the cable shield is connected to the signal ground only, it will be clamped to +/- 0.6 V above or below chassis/AC ground.

PROTECTION FEATURES

The ICA™ Series incorporates protection features derived from Peavey’s extensive experience with reliability. The amplifiers are ruggedly built from high-quality components and feature comprehensive protection circuits to protect your amplifier from those “real world” occurrences.

CLIP LIMITING

At the amplifier’s full power, or clipping point, the channel gain will automatically be reduced, guarding the loudspeakers against damaging high power and continuous square waves that would otherwise be produced. This is indicated by illumination of the CLIP LED. Normal program transients will not trigger Clip Limiting, only steady or excessive clipping will. Operation is virtually transparent in use and full signal bandwidth is maintained.

LOAD FAULT CORRECTION™

LFC is an innovative circuit that will instantaneously reduce channel gain to allow the amplifier to operate at a safe level into an abnormal load. LFC activation is indicated by illumination of the LFC LED. Moderate activation of LFC is inaudible in normal use. In addition, if extreme low impedance or a short circuit is encountered during high signal level conditions, the amplifier’s output relay will open.
