VCP: Protoype voltage-controlled panner module - PCB/panel or PCB
6 in stock.
The voltage-controlled panner - a module with many uses throughout the home: use it to split a signal into two separate channels for processing (eg. send one output straight to a mixer and the other through a filter) or even as a slightly braindead VCA by only using the 'right' channel.
The control voltage range is 0-10V, with 0V being 'full left' and 10V being 'full right' - there's a trimmer potentiometer on the main board which allows you to adjust the left-channel gain. Negative CVs will be rejected, so if you're using a through-zero control voltage then you may need to apply an offset to your CV.
Please note that this module takes a mono, not stereo, input - what it does is split the signal into 'left' and 'right' channels which can be sent to two other sources.
For best results, this build will require a two pairs of matched NPN transistors (2N3904, 2N2222 or equivalent) and two pairs of matched 10k resistors (1% resistors are good enough) - there are two surface mount components which will be pre-soldered.
PCB/panel sets will contain a PCB and a 6HP panel fabricated from 1.6mm FR4 fibreglass.
The BOM and schematic can be found at https://github.com/yorkmodular/voltage-controlled-panner
Design files for the panel are also there if you want to fab your own.
