OWNER'S MANUAL - 1

Thank you for purchasing the Lanzar MNX Class-D amplifier. Rest assured you have purchased a quality
product
designed and engineered to give you many years of un compromised musical service.
The MNX Class-D amplifier has been designed using the latest in electronic technology available today.

This mono subwoofer amplifier is the result of advanced high speed switching technology that overcomes the
less-efficient class-D design. The MNX Class-D amplifier reflects your true appreciation for powerful bass
reproduction in the mobile environment.

This amplifier is designed for low-frequency information only and it is not capable of reproducing any
mid/high-frequency information.

This is due to the noise introduced into the signal by the switching speed of the power supply, which must be
filtered out of the audio signal.

The power supply incorporated into MNX amplifier is a DC to DC switching power supply designed to
have adequate headroom for even the most demanding peak and dynamic range found on today's cds
and recording.

CLASS-D DESIGN

Low - frequency information for subwoofer only.
High efficient power

POWER SUPPLIES

Stiffly regulated PWM power supplies.
MOSFET switches maintain rated power over a wide range of battery voltages.

LOW PASS FILTER

Adjustable from 50Hz to 250Hz with a slope of 24dB per octave.
This allows for the adjustment of the upper point of the frequency bandwidth
and the respective subwoofer.

VARIABLE SUBSONIC FILTER

Adjustable from 15Hz to 45Hz with a slope of 24dB per octave.
This allows for the attenuation of frequencies that are mostly inaudible and
cause unnecessary strain on the amplifier.

PROTECTION CIRCUITRY

Protection against thermal, Overload and short circuit conditions.

REMOTE DASH-MOUNT GAIN CONTROL

This amplifier come complete with a compact remote GAIN CONTROLLER
which can be conveniently mounted on or under the dashboard of your car.
