4. Triggers
Each channel pair of the A1240 has its own Remote
Turn On/Muting circuit (TRIGGER INPUTS 1/2-11/12).
Individual channel pairs can be muted or un-muted inde-
pendently of any others. A SYSTEM TRIGGER IN port
allows all channels 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 A1240s or other
amplifiers, or to perform automated functions desired by
the user. Use 3.5mm mono interconnect cables to make
Trigger connections.
SYSTEM TRIGGER IN
To mute/un-mute all channels simultaneously, connect a
system-wide 5-24 Volt DC triggering source to the SYS-
TEM TRIGGER IN port using a 3.5mm mono intercon-
nect cable. Examples of triggering sources include an
ELAN Multi-Zone Controller’s SYSTEM TRIGGER OUT or
REMOTE OUT, an A/V receiver’s switched outlet con-
nected to a power supply, or a +12VDC TRIGGER OUT
from another ELAN amplifier.
SYSTEM TRIGGER OUT
Whenever the A1240 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 TRIGGER OUT include muting/un-mut-
ing other amplifiers, triggering the switched outlets of
a Z•Power Controller, or triggering automated events
using ELAN
®
Sense Sensors and VIA! SR-1 or VIA!2-SS1
devices.
TRIGGER INPUTS 1/2-11/12
To Mute/Un-Mute specific pairs of channels, a zone-
specific triggering source must be used. Any 5-24 Volt
DC source may be used to trigger these specific inputs.
This application gives additional control in advanced
systems. Examples include: ZONE TRIGGER OUT-
PUTs from an ELAN Multi-Room Controller, multiple A/V
receivers triggering separate A1240 inputs, or outboard
sensors located in certain areas to trigger specific in-
puts of the A1240.
