CONFIGURATION 10 – EXTERNAL AMPLIFIER IN A ZONE FOR MULTIPLE ROOMS
The preamplifier output connectors on the ZR-8630AV for zones 4, 5 and 6 have a fixed/variable setting. Use
the fixed setting with an external amplifier to divide a zone into individual rooms using conventional Niles
impedance-matching volume controls.
In Figure 14, Zone 6 has been expanded into four rooms. Each room can be ON/OFF individually and be set
at a different volume level.
The speakers for the master bedroom connect to the internal zone amplifier of the ZR-8630AV. A Select
™
Master
Keypad Module in the master bedroom controls ON/OFF, source selection, and source operation for the entire
zone. However, the volume and mute buttons on the Select
™
Master Keypad Module affect only the speakers
in the master bedroom.
Impedance-magnifying volume controls allow individual control of the speakers connected to the external
zone amplifier in the master bathroom, the walk-in closet, and the terrace.
