The A1240 Power Amplifier is designed
to provide a reliable, affordable and
feature-rich solution for multi-room
audio systems requiring up to twelve
channels of amplification. Building on
ELAN’s proven analog technology
developed for the S6, Z•660 and Z•300,
the A1240 adds advanced features like
audio sensing, stereo/mono bussing and
trigger inputs/outputs to make it the
premier amplifier in its price range.
Using easy-to-configure dip switches, any
A1240 input can be combined or bussed
to any output without the use of
additional patch cables. Bus loop outputs
allow for easy connection to additional
amplifiers, A/V receivers, etc.
Six +12VDC trigger inputs allow
each pair of channels to be activated
independently. The system trigger input
turns on all channels when a signal is
received, while the system trigger output
sends a +12VDC pulse whenever any of
the channels of the amplifier are on.
The A1240’s audio sense circuit mutes or
un-mutes channels based upon whether
an audio signal is detected or not.
Each channel also features an audio loop
output, making for the easy creation of
stereo and mono sub-zones for routing
independent channel audio to additional
amplifiers or audio processors. Individual
channel level adjustments allow
fine-tuning each channel’s level using
precision potentiometers. Removable,
locking speaker terminals make quick
and secure speaker connections.
