Audio send and receive

Motivation

This module is thought for sending and receiving audio signals. I use it to add some external effects to my modular. Albeit simple, it is very useful. For connecting pedals and external CV sources I recommend my Pedal/CV Send and Receive module

Specs and features

• Attenuates the out signal to line level
• Amplifies the input signal to modular level
• Amplitude control for in and output
• Runs on +/-15V and +/-12V without changes
• Power consumption around 10mA each rail

Implementation

Schematic

Description:

The outgoing signal is attenuated 1:4 with IC1B. P1 sets the output signal level. The incoming signal is amplified 1:7 with IC1D. P2 sets the input signal level.
