VOLCM-2 Mono Volume Control
VOLCM-2 Module
The VOLCM-2 is an active single-channel volume control module. It uses a 10K linear potentiometer to provide an approximately logarithmic gain curve. Different variants provide different maximum gain values (from +3dB up to +16.8dB). It uses a single NE5532 device. The module is powered with a bipolar supply (+/-12 to 16V) using a power supply such as the PSU-12. The module measures 38mm x 28mm.
