NEDSP1062-KBD Operating Manual
1. Introduction.
The
NEDSP1061-KBD
is a modular solution for noise
reduction. It incorporates Digital Signal Processing (DSP)
technology to provide up to 35dB of noise cancellation
and 65dB of tone reduction. The module features an on
board power amplifier to allow it to be easily incorporated
in to existing equipment by installing the module in line
with the loudspeaker. All functions of the module are
controlled by an easy to use keyboard.
