Rear Panel Controls (cont.)
25. Aux Input – Plug in a line level stereo audio source such as a CD or MP3
player in this input. The 1/4 inch stereo (TRS) Aux Input mixes the signals
to mono when amplifi ed.
26. Monitor In & Out – The monitor feature on the SA220 allows two
performers, each with a SA220, to send their own mix to each other. The
Monitor level on the front panel then blends in the other players mix. It
essentially acts as a monitor, allowing the performer to hear the other
player more easily.
The Monitor In may also be used as another audio input, just like the Aux
Input. The Monitor Out can serve a secondary function as another line
level mix output. This output is always ground isolated to prevent ground
loop hum.
27. Mix D.I. (Post) – Plug in here when you wish to send signals from both
Channels and Aux Input to a mixing console. This post-EQ output is always
ground isolated to prevent ground loop hum.
28. Mute Foot Switch – Plug a mono, on/off (latching type) foot switch
into this jack for remote access to the Mute feature. The Mute Footswitch
duplicates and overrides the front panel Mute switch.
29. AC Power Input – Connect the SA220 to the AC mains supply here.
