+48V button
It supplies the Phantom power (DC+48V) to the MIC
1 - 4 terminals for condenser microphones.
When it is ON, DC+48V is output for the MIC
terminals except for the MIC4 on the front panel.
Notes
• Make sure to turn the MIC fader toward minimum before
connecting or disconnecting any cable or turning the +48
button to ON.
• Make sure to connect a line equipment to ST1 to ST3 inputs.
• When using a microphone powered by +48V and a dynamic
microphone simultaneously, the dynamic microphone may
not show its performance to the full.

3
Check the up and down sides of the tuner unit, and
insert it into the slot.
The upper slot corresponds to MIC1 and the lower slot
to MIC2. (Set the group and channel of the tuner unit
to same as wireless microphone's one.)
NOTICE
To prevent breakdown or injury, do not put your hand
inside of the slot except when you install or remove the

power is consumed.
Notes
Take the following precautions to prevent interference
and noise.
• If there is a TV broadcasting station nearby, to avoid
possible interference from its broadcasting, do not
use that station's channel.
• When simultaneously using two tuners, always set
