This power amplifier can be used as part of the new multi channel
system, or as a
standalone 2 channel amplifier. This amplifier
features the new Electrocompaniet standard, SPAC, to send internal
status information to the preamplifier. The new preamplifier EC4.9 will
automatically switch AW2x120 from 2x120W to 1x400W when a 2 channel
source is selected. When a multi channel source is selected it will be
switched back to 2x120W.
