CONFIGURATION 8 – EXTERNAL AMPLIFIER IN A ZONE FOR MORE POWER
Each zone of the ZR-4630 provides RCA preamplifier output connections for the connection of external ampli-
fiers. External amplifiers can be used to provide more power in a zone.
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.
