Mini Line Mixer Example Connection Diagram
(note: stereo connections are denoted by dashed lines)
The above diagram shows an example of how a parallel effects system can be created with the Mini Line
Mixer. An audio loop switcher sends the audio signal to multiple effects processors, which are mixed
together along with the dry signal. The output of the Mini Line Mixer is sent to a stereo power amp.
Please refer to the RJM Music web site for more connection diagrams and other how-to information.
A note on signal impedance: The Mini Line Mixer is designed to work with low impedance signals, like
those in an amplifier’s effects loop. In order to use it with a high impedance signal like an unamplified
guitar signal, the signal needs to go through a buffer before reaching the Mini Line Mixer.
