Ecler MPA4-150R Notice D'utilisation page 6

The MPA6-150R amplifier station consists of six 170W/4Ω amplifiers which can be configured
through a set of switches found on the rear panel. This allows multiple amplification setups useful in
many situations, for example:
•
Six mono amplifiers for six different mono inputs.
When setup this way, the MPA R is able to amplify six different audio signals, each one having a
dedicated volume control.
•
Six mono amplifiers for one common mono input.
The amplifier operates now with just one input signal for all amplifiers, but preserves the ability to control
each channel volume independently. This setup is useful when distributing signals to different zones.
•
Six mono amplifiers for one common stereo 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.
•
Three stereo amplifiers for three different stereo inputs.
Each stereo channel offers a dedicated volume control. Useful for addressing three zones with three
different stereo signals.
•
Three stereo amplifiers for one common stereo input.
This setup is similar to the previous example but the input is now a single stereo signal which is fed to all
three amplifiers.
•
Three bridged amplifiers for three different mono inputs.
Useful for addressing three zones with three different mono signals. Each bridged channel offers a
dedicated volume control. With a bridged amplifier you obtain doubled output power with a load of at
least 8Ω.
•
Three bridged amplifiers for a common mono input.
The MPA operates now with a single mono signal for three mono amplifiers, each one with its own
volume control.
•
Three bridged amplifiers for a common stereo 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.
•
Four mono amplifiers and one bridged amplifier for one common mono input.
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.
