WEISS A1 500 Series mic pre and de-esser

Switzerland based Weiss Digital Audio known worldwide for making some of the best high end digital audio equipment (first time I encountered Weiss was in a mastering session many years ago) has released the A1 Mic Pre. 

The A1 has all the standard controls but also includes a De-esser with variable frequency, bandwidth and threshold controls plus a listen switch which makes it that much easier to zone in on sibilance. There are also 8 dip switches located on the bottom of the unit which allow you to further adjust the response of the de-esser.

A1 Features:

- Microphone preamplifier gain rotary switch
- +48V phantom power switch
- 24 dB pad switch
- High-pass filter frequency and bypass switch
- De-esser frequency potentiometer
- De-esser bandwidth potentiometer
- De-esser threshold potentiometer
- De-esser bypass and listen switches
- Output level potentiometer (transformer balanced)
- Polarity switch
- "Listen" switch to simplify zooming in on offending sibilances
