MEMO
The following explanation and illustration covers the
INPUT (1L, 2R) jack section. The Rubix44 additionally has
INPUT (3L, 4R) jacks with placement and functionality that
are equivalent to the INPUT (1L, 2R) jacks. This explanation
applies in the same way to the INPUT (3L, 4R) jack section.

or INPUT 3L jack. The sound level will be very
low if you connect directly to the INPUT 2R or
INPUT 4R jack.

connected to the XLR connectors. Supplying phantom
power to a dynamic microphone or to an audio playback
device may damage the equipment. For details on the
requirements of your microphone, refer to its owner's
manual.
5 Minimize the volume before you turn phantom power on
or off. Even if the volume is minimized, turning phantom
power on/off might make a sound, but this is not a
malfunction.
