Rear Panel Audio In Jacks; Input Source Examples - Kurzweil K2700 Musician's Manual

Rear Panel AUDIO IN Jacks

The rear panel AUDIO IN LEFT and RIGHT jacks each accept either a 1/4" "phone plug"
in the center hole, or a 3-pin "XLR" male plug in the outer ring, and can accept signals at
line, instrument, or microphone levels. An internal switch detects which kind of plug is used
and automatically selects the appropriate preamp.

Input Source Examples

The K2700 AUDIO IN jacks can adapt to a variety of signal sources and types. See below for
details on setting the front panel AUDIO INTERFACE section controls appropriately.
For each signal type below, use the rear panel AUDIO IN Jack Type and Cable/Plug Type
listed in the right column, and set the AUDIO INTERFACE section controls listed in the
left column to the settings in right column. Finally, use the GAIN knobs in combination
