LINKING TWO MRC88 CONTROLLER/AMPLIFIER UNITS

To connect two systems, simply connect the supplied DB15 Expansion Cable to the EXPANSION Port on the

rear of one unit to the EXPANSION Port on the other – Figure 3-(30). These units should be placed either side

by side or if installed in a 19” (483mm) equipment rack, leave 2 rack unit spaces (2U space) between the two

units [One Rack Unit space = 1-3/4” (44.5mm) in height].

CAUTION: Do not place these units directly on top of each other. This may cause damage to the units

due to increased heat dissipation.

ONNECTING SOURCE COMPONENTS

When connecting two units together, designate one unit as the PRIMARY Unit (Zones 1-8) and the other unit as

the SECONDARY Unit (Zones 9-16). All source components should be connected directly to the PRIMARY

Units Source A/V Inputs – Figure 3-(22). Use the PRIMARY Units Audio and Video Loop-Thru connectors –

Figure 3-(23) to feed the source component inputs of the SECONDARY Unit – Figure 3-(22).

All of the source components emitters should be connected to the PRIMARY Units IR Emitter Output Ports –

Figure 3-(26). This rule applies to the SENSE INPUTS also.
