1. Combo input jacks
These are analog audio input jacks with microphone
preamps. They accommodate both XLR type and phone type
plugs, allowing you to use the type appropriate for the
device you’re connecting. They also support either balanced
or unbalanced connections.
Connect a microphone to XLR type jacks. The XLR type jacks
can provide 48 V phantom power, allowing you to connect a
phantom-powered condenser microphone. In this case, set
the rear panel Phantom power switch (23) to the ON
position.
* This instrument is equipped with
balanced (XLR/TRS) type jacks. Wiring
diagrams for these jacks are shown on
the right. Make connections after first
checking the wiring diagrams of other
equipment you intend to connect.
2. Input sensitivity knobs
These adjust the input level of the signals that are input from the front panel combo input jacks (1).
3. Input impedance select switch
This lets you select either high impedance (Hi-Z) or low impedance (Lo-Z) as appropriate for the
device you’ve connected to the phone type input jack of combo input jack (1) INPUT 2/R.
If you’ve connected a guitar or bass, turn the input impedance select switch on (pressed inward )
to select high impedance (Hi-Z). If you’ve connected a synthesizer or an analog audio device, turn the
input impedance select switch off (outward position ) to select low impedance (Lo-Z).
The phone type jack of the combo input jack INPUT 1/L is fixed at low impedance (Lo-Z).
