ZONE 3

Figure 12

In Figure 12, an external amplifier has been connected to zone 3. Using an amplifier with more than the 30W per channel provides the zone with more volume for listening in large rooms and outdoors.

Important Note: When using preamplifier outputs for zones 4, 5, and 6, the fixed/variable switch must be in the variable position for this configuration.
