Weiss A1 Mic amp De- esser

The A1 is the first analog input/output only product from Weiss Engineering. A state-of-the-art microphone/line pre-amplifier with a De-esser in the popular API 500 Series format.

The side-chain of the De-esser uses a DSP – unique but advantageous for the precision of the side-chain and enabling the use of a very low noise gain element.
Two modules can be side-chain linked for stereo operation. It has a transformer balanced wide level range input with a pad for line level sensitivity. The input gain is set with a sixteen position switch. A low cut filter is useful for microphone work.

£800
The output is also transformer balanced and has an additional potentiometer to set the output level independently from the levels the de-esser is running at. A polar its switch allows to change the absolute polarity of the output signal.
The de-esser section uses a bandpass filter to split the audio band. The bandpass filter parameters are the center frequency and the Q.
The Threshold parameter defines the sensitivity of the de-esser side-chain. A few attack and release times and ratios can be selected via DIP switches at the bottom of the unit.
