Description

Meant for a Bluetooth dongle, to send and receive signals to and from the modular. A USB socket powered by a 1 A 5 V regulator, from the +12 V rail. RX takes a stereo line signal, with 22x gain, out to two mono jacks, L and R. TX takes two synth level mono signals, brought down to about a tenth, out of a stereo jack; one signal patched into IN L feeds IN R through its switch. Plug a dongle into the USB socket and its audio into RX IN, and send signals from a phone into the synth at synth levels.
