Two bridged amplifiers for two 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
.
Two bridged amplifiers for a common mono input
The MPA operates now with a single mono signal for two mono amplifiers, each one with its
own volume control
Two bridged amplifiers for two different stereo inputs
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
Two 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.
One stereo amplifier and one bridged amplifier for a common stereo input.
Useful for setups where a stereo amplifier drives the mid-range and high frequency speakers
while a second, bridged amplifier drives 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 750VA. It's important that your mains installation is adequately
scaled to these power demands.
You should provide the device with a suitable earth connection, Rg= 30
Ω
or less
The environment should be dry and completely dust-free
When connecting / disconnecting cables or doing other manipulation always pull out
the mains supply cable
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 8A fuse (25). 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.
