* Microphone input for the unit uses a balanced-type (XLR/TRS) jack which is wired as
shown in the figure. Check the wiring of the device you want to connect and make the
connection.
Depending on the specifications of the input device, the phase of the sound may be inverted,
resulting in input that is not correct. If this happens, refer to “Phase” (p. 18).
If you’re connecting a microphone that requires a phantom power source, refer to “Phantom
Power (+48V)” (p. 17).
Phantom power is not suppled to phone jacks.
Connecting the Output Equipment
Line Output (LINE OUT)
Use an XLR-type plug to make the connection for output to a mixer, recorder, or the like.

Setting the Output Level
Select level switching [OUTPUT LEVEL] on rear panel. Level should be selected in accordance with
output destination device. This value serves as the reference for the output level.
Generally, commercial equipment is designed for +4 dBu, while consumer equipment is
designed for -16 dBu.
