good tip on the mult! What will happen if you offset the incoming audio?
Hopefully nothing, but keep in mind that you are adding a DC offset voltage to the audio signal if the Offset control isn't zeroed. What can happen?
Depending on the amount, a DC offset will produce an audible 'pop' if you connect the audio output to an amplifier (think of what happens if you were to connect a 9V battery across a speaker - then imagine that effect amplified). Also, some audio processing circuits can become unbalanced with a significant DC signal present.
I'll leave a complete technical explanation to the EE's on the forum, but it's just good practice to observe basic precautions before you start plugging anything into the CV mixer. Although this device CAN mix audio signals, it's important to understand that it wasn't designed to be used this way, and damage (however unlikely) could result if precautions aren't taken.
Better to be safe than sorry...
