1. INTRODUCTION
Audiophile Circuits League
-VC PANNING AMPLIFIER is especially designed to
process audio signals, dynamically positioning them in a stereo feld. If mono
signals are processed, the unit can be also operated as two standalone VCAs.
The Circuit is designed for low distortion, low CV feed-trough and low noise.
The module has two exponential response VCAs with voltage and manually
controlled gains, input level attenuators and overload indicators. When no jack
is connected to IN 2 and CV 2 inputs, they are normalized to IN 1 and CV 1 inputs
respectively. Some of the possible confgurations with this arrangement allow
the gain of both channels to be controlled together with one CV, while
processing different audio signals, or both channels to be operated individually,
if needed. The gain balance between both VCAs and hence the panorama
position of a stereo signal is manually and voltage controllable. The common
gain of the two channels is also manually adjustable with a single pot.
