Connections; Two Stereo Inputs; Four Monaural Inputs; Two Monaural Sources As Stereo Inputs - Radio Shack 4-Channel Stereo Microphone Mixer Owner's Manual

The Basics

connections

Use shielded audio cables (available at RadioShack) for all input
connections. The connected input source's signals are routed
to the corresponding channel on the mixer. For example, if you
connect a CD player to AUX 1 L and AUX1 R, you will adjust CHANNEL 1
and CHANNEL 2 to mix and play audio. See "Operation" on Page 10.

Connect the line level outputs from one device to the mixer's AUX 1
INPUT R and L jacks. Connect the line level outputs from the second
device to the mixer's AUX 2 INPUT R and L jacks.
four stereo sources as monaural inputs
Use shielded Y-adapters at each source's left and right outputs, and
connect a separate stereo source to each input jack (AUX 1 R, AUX 1 L,
AUX 2 R, or AUX 2 L) on the mixer.

four monaural inputs

Connect each monaural device to each input jack (AUX 1 R, AUX 1 L,
AUX 2 R, or AUX 2 L) on the mixer.

two monaural sources as stereo inputs

Use shielded Y-adapters at each source's monaural outputs, and
