2. DESCRIPTION

24-Bit dual engine feedback destroyer. With a state of art DSP algorithm, detects feedback
frequencies and suppress them by using the notch filter automatically and store in memory. With
automatic control of the notch filter frequency bandwidth, it suppresses the feedback signal without
any audio quality loss.
LS-320 is equipped with 24 parametric programmable filters, 10 programs to fit different
environments, as well as balanced inputs and outputs, XLR and Jack terminals.
Its characteristics are as follows:
o Accurate frequency search
While the unit is in suppressing mode, the frequency of the filter is dynamically changed. The
feedback suppression is highly accurate with maximum error of 1 Hz.
o Adjustable suppressing bandwidth
The suppressing bandwidth is adjustable with both single point filter and automatic filter. The
bandwidth options are 1/10 or 1/5.
o Showing different parameters
The filter's different parameters are displayed in the 2 x 16 digital numeric back-lit LCD screen.
In AUTO mode it shows all parameters, incl. frequency and bandwidth. In SING mode, displays
frequency and bandwidth, and they can be adjusted.

3. CONTROL PANEL
