correctly.
• When the HI-Z switch is turned on, the signal from the XLR-
type is cut off.

equipment.
• Do not connect or disconnect any devices while the
phantom power switch is turned to ON.
• Set all output level controls to the minimum before turning
the phantom power switch to ON or OFF.
• When connecting devices not requiring phantom power to
the [MIC/LINE 1/2] jacks, make sure to turn the phantom
power switch to OFF.
CAUTION
To protect your speaker system, leave the
monitor speakers turned off when turning the
[INPUT 1 HI-Z] switch on/off. Turn all output level
controls down to their minimum. Neglect of
these precautions may result in loud noise
bursts that may damage your equipment, your
ears, or both.
Setting optimum recording levels
