BZA-3000D

Class-D mono block MOSFET neon car audio amplifier

INTRODUCTION...

Thank you for purchasing the Blitz Class-D amplifier.
Rest assured you have purchased a quality product designed
and engineered to give you many years of uncompromised
musical service.The Blitz 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 Blitz 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 Blitz 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.
