Ecleree MPA4-80, User Manual

5

The MPA6-80 amplifier station consists of six 75W/4

Ω

 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 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 both amplifiers. 

Three bridged amplifiers for three different mono inputs. 

Now you get a typical stereo  amplifier configuration. With a bridged amplifier you obtain 
doubled output power with a load of at least 8

Ω

. 

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 amplifier does not include any filtering) 
 
 
3. INSTALLATION 

 
3.1. Placement and mounting 
 

The amplifier is a 2 RU high 19'' rack module. It is supplied with plastic washers in 

order not to damage the unit when tightening the screws.  

It is important that the amplifier, as a heat source, is not placed next to other 

equipment nor exposed to high temperatures.
