Combo input jacks

These are analog audio input jacks with mic preamps.
They accommodate either XLR or phone plugs,
allowing you to connect a variety of equipment.
Either balanced or unbalanced signals may be
connected.
Phantom power (48 V) is provided for XLR type
connections, allowing you to connect condenser mics
that require phantom power. In this case, turn on the
phantom power switch (19) located on the rear
panel.

* This instrument is equipped with
balanced (XLR/TRS) type input jacks.
Wiring diagrams for these jacks are
