Can you combine audio signals?
The simplest way to combine two signals is with two resistors as shown in the circuit diagram below. The ground connecton is shared between both inputs and output. The quality can be improved by adding an output buffer (opamp), but that complicates things in requiring an IC, power supply, (de)coupling caps, ...
What are line level signals?
Line Level. Line level signals are the highest level signals before amplification. This is the type of signal that typically flows through your recording system after the preamplifier stage and before the amplifier that powers your speakers. The two types of line levels are consumer and professional.
Is Line Out balanced or unbalanced?
The line in/out connections on consumer-oriented audio equipment are typically unbalanced, with a 3.5 mm (0.14 inch, but commonly called "eighth inch") 3-conductor TRS minijack connector providing ground, left channel, and right channel, or stereo RCA jacks.
Do mixers output line level?
So, 1 volt was a "line level" signal. ... A mixer will not only boost a microphone level signal, but it will also combine multiple signals together into a single output. There are also devices called Mic preamplifiers or Mic-to-Line amplifiers. These are available as single-channel or multi-channel devices.
