Parasound ZoneMaster 4 Owner’s Manual Page 11
Turn On Options
The setting of the rear panel Turn On Options Switch determines whether both zones turn on and off
together or if each zone turns on and off individually. There are three positions for this switch:
Manual All
Pressing the Power button on the front panel will turn both zones on and off together.
12V All
When a 12V trigger voltage is applied to the 12V Input jack marked “Trigger For All Zones” both
zones will turn on together. When the trigger voltage is removed both zones will turn off together.
Note: Whenever the 12V All switch is set to 12V All the ZoneMaster 4’s front panel
Power button will be disabled to prevent the amplifier from being turned on or
off manually or by mistake. The 12V turn on trigger circuit in the ZoneMaster
4 requires a mere 5mA from the 12V trigger source.
Audio/12V By Zone
Each zone can be turned on and off individually by either an audio signal or a 12 volt
trigger. The setting of the two Zone 12V / Audio switches determines whether an
individual zone is turned on and off by 12 volts or turned on and off by audio. Whenever
the switch is set to “Audio/12V By Zone” the front panel Power button will be disabled to
prevent the amplifier from being turned on or off manually or by mistake.
