Trigger options, the A12 can be customized for even the most complex systems. Independent Stereo Zones The A12 is designed to easily power six independent stereo zones without any special setup procedures. This is the standard configuration for most multi-zone audio distribution systems. In the drawing below, each pair of speakers will have independent line-level volume control. - Page 14 INSTALLATION MANUAL Two Room Stereo Zone By using the A12’s Buffered Loop Outputs, an additional pair of speakers can be added to a zone. In this example, both pairs of speakers will ramp volume up and down simultaneously. Two Room Stereo Zone •...

Page 16: S66A Application
ELAN’s S66A Integrated Multi-Room Controller has built-in amplification for six stereo zones as well as six sets of preamp outputs for the addition of sub-zones. The A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones. -

ELAN’s S86A Integrated Multi-Room Controller has built-in amplification for six stereo zones as well as six sets of preamp outputs for the addition of sub-zones. The A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones. -
Page 18: S128P Application
ELAN’s S128P Integrated Multi-Room Controller has variable preamp outputs for eight stereo zones as well as eight sets of fixed preamp outputs for the addition of sub-zones. The A12 is ideally suited to amplify these subzones using rotary or electronic volume controls if separate volume up/down functionality is desired in the sub-zones. -

The term BUS is defined as the ability to route a signal from one place to another. Traditional busing is done using audio patch cables to route these signals. The use of Bus Switches, such as the ones on the A12, eliminates the need for additional patch cables and adds to the flexibility of signal routing. -

Page 26: Triggers
INSTALLATION MANUAL Triggers Each channel pair of the A12 has its own Remote Turn On/Muting circuit (TRIGGER INPUTS 1/2-11/12). Individual channel pairs can be muted or un-muted independently of any others. A SYSTEM TRIGGER IN port allows all chan- nels to turn on or mute simultaneously. All TRIGGER INPUTS can receive 5-24 Volts AC or DC. The 12 Volt DC SYSTEM TRIGGER OUT can be used to turn on other equipment, additional A12s or other amplifiers, or to perform automated functions desired by the user. -
Page 27: System Trigger In
SYSTEM TRIGGER OUT Whenever the A12 is powered On an any channel is On, the SYSTEM TRIGGER OUT becomes active. This output sends a +12VDC 100mA signal to other devices with a Trigger Input. Examples of proper usage of the SYSTEM TRIG- GER OUT include muting/un-muting other amplifiers, triggering the switched outlets of a Z•Power Controller, or trig-... -
