input signals? While this does work as a mixing technique, it has a noticeable downside.
The two input signals are always interacting in the mix .
Here’s an example. Imagine that signal one is currently active – we’re getting a triangle
oscillation at full volume. At the same time, signal two is currently silent – so the input is
sitting at 0 V permanently.
Since our mixer is creating the average of the two signals,
the output will be the triangle oscillation at half volume .
You can test this by tying one input resistor to ground (simulating a silent input) – or not
connecting it to anything at all to (removing the input completely). You should be able to
hear the volume go down significantly once you apply the „silent“ signal. This is not really
great.
Normally, you’d expect a mixer to give you the oscillation at full volume in this
case – the state of the other signal shouldn’t matter .
