RCA Input - for connecting signal patch cables (interconnects) from the preamplifier to the amplifier. *The AV125. 5 does not have amplifier channels 6 & 7. Balanced/Unbalanced Input Select - this switch is used to configure an AMPLIFIER PAIR for use as either balanced (XLR) or RCA unbalanced line inputs. This switch controls two amplifier channels and allows signal patch cables (interconnects) to be sourced from either balanced or unbalanced, preamplifier/processor or line outputs. *The AV125. 5 does not have amplifier channels 6 & 7. Amplifier Control Input/Output - provides remote switching of the amplifier's standby on/off feature.

In a system for use with the AV125. 7 or AV125. 5, adjustment of the volume level must performed using the external preamplifier/processor. INPUTS The AV125. 7 and AV125. 5 allow signal patch cables (interconnects) to be sourced from either balanced or unbalanced line level preamplifier/processor outputs. The positive (+) post should always be connected to the speakers (+) jack. The negative (-) post should always be connected to the speakers (-) jack.

Preplanning is essential in order to maximize system efficiency. We recommend the following as a means of helping you reach that goal. Make a diagram of your proposed system by laying out the relative location of each component in the system. Then lay out the proposed cable runs between them. Number each cable and record its length on the diagram for future use. Cable runs are critical in that they must be kept away from the sources of power radiation (amplifiers, power cords, heaters, appliances, etc. ). For safety reasons, they should also be kept out of traffic areas. The process of optimizing the system will include the type of cable, the length of the run, and the obstructions it must deal with along its run. Your dealer can advise you on the products available and their relative merits. If building custom length audio cable is not your strength, you dealer should be able to help you with that as well.
