Multiple Output Distribution Amplifier Configuration

JUMPER SETTING

For use as a distribution amplifier, or in any situation where more than

four outputs per channel are required, the MSR-604 II system may be

reconfigured by moving internal jumpers. Up to sixteen adjacent

channel sections, a total of sixty four outputs may be driven from a single

input stage.

The simplified block diagram, Figure 12 shows the segmented internal

bus which runs between adjacent channels. This bus is continued via

the multiway LOOP connector between MSR-604 II units, allowing

blocks of D.A. channel to span several output sections. Figure 12

shows the bus and the bus linking headers in their default settings, i.e.

each channel input section is connected to its own output section.

The default jumper positions are identified on the PCB by a white

block printed adjacent to the relevant jumper pins. By way of exam-

ple, Figure 13A illustrates a typical distribution amplifier arrangement

where Channel 1 input section is used to drive its own and Channel

2’s output sections and, likewise, Channel 3 input is driving the out-

puts of both Channel 3 and Channel 4.
