5.Line Inputs. These RCA-type jacks are the audio inputs for each of the amplifier pairs. Connect them to the OUTPUT jacks of the driving preamp with good quality RCA-type patch cables. Note that the inputs are marked LEFT-1-RIGHT, LEFT-2-RIGHT, etc., signifying the stereo channel pairs. Both the LEFT and RIGHT jacks are also active when the MODE switch (item #7) is set to the MONO or BRIDGED mode.

6.Input Level Control. This screwdriver adjustable control (for each stereo or bridged pair) allows the input level for full rated power output to be adjusted over a range of 0.2 volts to 3 volts. 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 potentially destructive power levels.

7.Mode Switch. Switches the amplifier pair between STEREO, MONO and BRIDGED modes.

a)In STEREO mode, the two amplifiers operate independently of each other for 35 Watts of output each.

b)In MONO mode, left and right input signals are summed internally for Mono output from each of the two amplifiers. Also, either the Left or Right (item #5) input may be used if the source is already a Mono signal.

c)In BRIDGED mode, the two amplifiers are bridged for a single channel of high power output (80 Watts @ 8 Ohms). Either the Left or Right input (item #5) may be used to drive the resultant single channel amplifier.

CAUTION: Be sure to have the POWER turned OFF when changing the position of this switch and when making the corresponding speaker connection changes (see also item #9, following).

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

ξ 120 V Version: 10 A 250 VAC, SLOW BLOW.

ξ 240 V Version: 5 A Time-Lag 250 VAC.

ξ 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.
