BOSS MR1950  
1950W 5 Channel Full Range, Class A/B Amplifier

The lowest impedance accepted by this amplifier is 2 ohms.
Amplifiers that are 2 ohms stable produce more power
resulting in more volume. This amp can comfortably power
speakers or subwoofers with all channel(s) being used
at a load of 2 ohms.

Bridging an amplifier means to combine channels of a multi-
channel amplifier to get more power or flexibility out of it.
For instance, on a 4 channel amp, channels 1 and 2 could be
used normally for your speakers, and channels 3 and 4 can
be bridged for more power to a single subwoofer. A 2 channel
amp can also be bridged to power a single subwoofer.

Class A/B amplifiers have long been known for their ability
to produce great quality sound while performing more
efficiently than pure Class A amplifiers. We have developed
a specific linear circuitry that further reduces distortion
while increasing both sound quality and power output.

Fixed High-pass filter gives you the ability to filter the
frequencies that pass through to the full range speakers from
a fixed frequency point.

Fully Marinized is the term we use for our Marine and
Outdoor products that are Weather Proof. We integrate
high-tech, state-of-the-art waterproofing materials plus
special UV coatings for plastic surfaces, coated circuit
boards and connections to protect the product against
the harsh outdoor elements and resist corrosion.

MOSFET stands for Metal Oxide Semiconductor Field-Effect
Transistor. MOSFETs are used either as a switch or to amplify
a signal. MOSFETs are superior to other FETs, because they
require less current to operate, which makes them
better suited for car audio.

If the amplifier gets too hot, the thermal protection circuit
turns the amp off and allows the amp to cool down before
turning it back on. If a speaker fails causing an electrical short,
the protection circuit will automatically cut the output and
remain in that state until the short is resolved. These safety
features give you peace of mind knowing the amplifier
is constantly monitoring conditions to protect itself.

The ability to boost or attenuate the sub level when
an amp and subwoofer are connected to the subwoofer
pre-amp output.

Switchable Input Sensitivity gives you the freedom
to connect the amp to any standard source unit and have
peace of mind it will be within range to properly match
the output of the source unit allowing you to use the volume
controls on your source unit the way it was designed.

Variable Bass Boost allows you to adjust the low bass
within the boost range to just the way you like it.

Variable Gain Control lets you balance the amps output
with the speakers or subs the amp is driving. To much gain
will lead to distortion and to little will lead to clipping.

Variable low-pass filter gives you control over the
frequencies that pass through to the subwoofer.
