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 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.

3. INSTALLATION

3.1. Placement and mounting

The amplifier is presented as a 2 unit 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.

3.2. Mains connection

The amplifier operates on alternate currents, depending on the country 110-120, 220-240V
50/60 Hz (see characteristics in the back of the unit). The power consumption at maximum
performance is 1650VA. It's important that your mains installation is adequately rated to these power
demands.
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30Ω
or less). The environment must be dry and dustless. Do not expose the unit to rain or water splashes,
and do not place liquid containers or incandescent objects like candles on top of the unit. Do not
obstruct the ventilation grids with any kind of material.
In case there is some type of intervention and/or connection-disconnection of the amplifier, it
is most important to previously disconnect the mains power supply. There are no user or serviceable
parts inside the amplifier.
You should avoid that the supply cable twists with the shielded signal cables, as this could
lead to unwanted hum.
In order to protect the unit from an eventual electrical overload or momentary power peaks
from the internal circuits it carries a T 16A fuse *. Should it ever blow up, unplug the unit
from mains and replace it with an identical one. If the new fuse blows again contact
immediately with our Authorized Technical Service. YOU MUST NEVER USE A HIGHER VALUE
FUSE.
* The fuse on the MPA6-150 is internal and should only be manipulated by qualified service
personnel.
