15.2. Phantom Power Supply

• Set the rear-mounted Input level selector switch to "PHANTOM" position only when connecting a

microphone which requires phantom power (+24 V, 10 mA) to the corresponding input terminal. Connecting
an equipment other than this type of microphone to the input terminal set to PHANTOM may cause the unit
to malfunction or may generate hum noise.

• Phantom power is not supplied to the phone jacks (MONO IN 1 – 6).
