Stereo Out Module

Here's a quick technical description of how the Stereo Out module works: The circuit buffers your stereo signals (left and right) with voltage followers, then adds an RC impedance to each channel as per standard interface method. The two signals are then applied to the left and right inputs of an 1/8" stereo jack. Taps for separate use of the voltage followers as buffers are available on the breadboard connector as are monitor taps at the stereo output itself. This module will soon be available in our store.

Use of the Stereo Out module is very straightforward. Just connect VDD and Ground, then your audio output signal(s), and you're done. Stereo audio will come out of the stereo jack, just insert a standard 1/8" cable into the jack. In this way you can hook your synth into a computer for recording, internet radio transmission, or live performance. It's also convenient that the opamps used on the Stereo Out board are capable of driving up to 25mA of current, so you can plug in any set of headphones and get clear, quality sound from your synth.

For convenience and versatility, taps are provided on both channels for the buffer output and for the monitoring of the stereo out signal. This way you can use the opamps as voltage follower buffers without using the stereo out jack in your circuit if you wish, and you can monitor the actual line-out signals on a scope if you choose to do so. The Stereo Out module is an easy to use, convenient, and versatile solution to getting the audio out of your synth.
