Ecler MPA4-150R Bedienungsanleitung Seite 5

The equipment operates with a single input signal for two / three mono amplifiers, and allows
to independently controlling their volumes.
o Two bridged amplifiers with two mono inputs or stereo inputs summed to different mono
inputs (MPA4-150R only)
You can obtain two zones with independent volume control and two different stereo signals,
but these stereo signals are internally converted to mono in each bridged amplifier.
o Two / three bridged amplifiers for a stereo input summed to a common mono input.
This setup is similar to the previous example but the input is now a stereo signal. The
amplifier adds both stereo channels together converting them into a mono signal.
o One stereo amplifier and one bridged amplifier with a common stereo input (only MPA4-
150R).
Useful for facilities with a stereo amplifier dedicated to satellite speakers (high and mid
frequencies) and a bridged amplifier for a subwoofer. This multichannel amplifier features a
low-pass filter to feed the subwoofer, and high pass filters for the high and mid range speaker
systems.
o Four mono amplifiers and one bridged amplifier for one common mono input (only MPA6-
150R).
Useful for setups with four amplifiers for mid-range speakers and tweeters and an extra
(bridged) amplifier for a subwoofer. This multichannel amplifier features a low-pass filter to
operate on a subwoofer system and a high-pass filter for the mid-range speakers and
tweeters.
