ACL – VC Dual Amp
The ACL VC Dual Amp is a high quality dual linear VCA with mixing function.The module contains two fully discrete voltage controllable amplifiers with linear characteristic. It is based on a new circuit design which delivers unheard clarity of sound. To this day there is no other VCA using this special technique!
The ACL VC Dual Amp offers a very low harmonic distortion in the whole linear gain range, no crossoverdistortion and no overshoots nor ringing. Furthermore it has a very high dynamic range which provides a lot of headroom. The VCAs will amplify the input signal very accurately and it will sound crystal clear, without any coloration, distortion or bleed.
Each channel has a Gain potentiometer for manually setting the VCA’s initial gain and a control voltage input which is equipped with an attenuverter for scaling the modulation. Thanks to normalized signal and CV inputs, both VCAs can be used in conjunction. – Great for processing stereo material. Furthermore, you can create voltage controlled panning effects and crossfades in next to no time. Beside the two individual audio outputs from each VCA, there is a Sum-output which provides the mix of the output of both VCAs and of the signal coming from the Aux-input. This additional input has no level control and is mixed at unity gain. Thus three different signals can be mixed together.
The amplifiers are also suitable for processing control voltages thanks to a completely DC-coupled signal path. Behind its simple appearance, this module shines with its functionality and sound quality!
