FIXED ZONE LINE OUT: CREATING SUBZONES
The PR-4Zi has six buffered, fixed-level audio/video outputs as shown previously in Figure 1 (p. 4).
When set to FIXED ZONE LINE OUT (Figure 7), the last four outputs can be used to create subzones
of each main zone. A subzone gets the same source selected for the main zone, and therefore needs
only on/off and volume control.
The lower portion of Figure 7 shows four amplified Russound A-KP2 keypads added to Zone 1. All
subzones get the same Zone 1 source, but will have independent on/off and volume control via the A-
KP keypad. Main zone control can be acheived by repeating IR commands in a sub-zone into the main
zones keypad input. D1 will accept IR signal for zone control.
