6.Line Inputs. These RCA-type jacks are the audio inputs for each of the amplifier pairs. Connect them to the Preamp Output jacks of Zone 7 & 8 of the MRC88 (or other driving preamp output) with good quality RCA-type patch cables. Note that the inputs are marked LEFT-A-RIGHT, LEFT-B-RIGHT signifying the stereo channel pairs.

7.Input LEVEL Control. This screwdriver adjustable control (for each stereo pair) allows the input level for full rated power output to be adjusted over a range of 0.2 volts to 3 volts (24.3 dB range). Normally you would adjust the driving preamp to maximum volume, then set this control to the maximum volume that the client desires for a given zone or room. This prevents the system from being driven to unwanted power levels.

8.FUSE. When required, replace only with a fuse of the same type and rating:

ƒ120 V Version: 10.0 AMP 250 VAC, SLOW BLOW.

ƒ240 V Version: 5.0 A Time-Lag 250 VAC.

CAUTION: Replacement with a fuse of higher rating will not protect the amplifier and will void the warranty.

9.SPEAKER Terminals. These plug-in 4-terminal screw type connectors permit speaker wire sizes up to 12 gauge. When making connections for the STEREO mode, be sure to observe the "+” and "–" polarity markings, just under the LEFT & RIGHT markings, for each wire pair going to the speakers.
