If you are installing the ZoneMaster ZM12 yourself, use input and output cables that are long enough to leave at least two feet of slack; that will enable you to pull the ZoneMaster ZM12 out of a cabinet to check or to change connections without inadvertently disconnecting cables.

This is an additional type of audio input that any zone can select as its source. The speaker level input enables the ZoneMaster ZM12 to connect to any audio receiver or stereo system even if it lacks preamp output jacks.

Speaker A and B Outputs The ZoneMaster ZM12 is equipped with connections for two speakers on each channel (labelled A and B). This unique feature gives system designers greater flexibility and can usually avoid the added expense, complexity, heat and power consumption of additional amplifiers.

B output terminals. All speakers will play the same Mono signal. The Mono Mode is particularly useful for applications such as bathrooms and hallways where mono speakers and a single speaker wire are more practical than separate L and R wires and two speakers.

The Level controls are particularly useful when an in-wall passive volume control is used to adjust the listening level in a room or zone. By reducing the ZoneMaster ZM12’s maximum output level you reduce the amount of power that is absorbed when the in-wall volume control level is turned down. This prevents the volume control from overheating or even vibrating from the stress of absorbing extra amplifier power.

When the trigger voltage is removed all six zones will turn off together. Note: Whenever the 12V All switch is set to 12V All the ZoneMaster ZM12’s front panel Power button will be disabled to prevent the amplifier from being turned on or off manually or by mistake.

Input jacks, Bus 1, Bus 2 Input Jacks or the Speaker Level Input. Audio Trigger Sensitivity: The audio trigger in the ZoneMaster ZM12 is not adjustable. It is calibrated for turn on at a very low volume leveI (an audio signal as low as 2mV). If you need a Zone to turn on at an even lower volume level, simply turn down both Level control knobs for that zone.

12V In Jacks The ZoneMaster ZM12’s “12V All” jack and six individual zone jacks are 3.5mm mini jacks (mono). To use a 12V trigger, insert the trigger wire plug into the jack and the plug at the wire’s other end into the AV receiver or house controller’s 12V Output jack.

Checking for Short Circuits on the Speaker Outputs If your ZoneMaster ZM12’s front panel indicators are illuminated red or alternate illumination between green and red this indicates a problem. Your first step is to immediately turn off the amp with its master AC power switch (above the AC cord inlet).
