phones, set the switches to the “ MIC” position. For channels with
high-level input signals such as electronic instruments and audio
devices, set the switch to the “ LINE” position.
u [HPF] (High Pass Filter) switches (Channels 1 – 3)
Turning this switch on ( ) applies a high-pass filter that attenuates
frequencies below 80 Hz in the signal by a slope of 12 dB/octave.
This function should be kept on when using vocals in order to reduce
noise from vibration or wind picked up by the microphone.
i [Hi-Z] switch (Channel 4)
Turn this switch on ( ) when you wish to connect instruments with
passive pickups such as acoustic-electric guitars or electric bass
guitars that do not have internal batteries. It enables such devices to
be directly connected to the mixer without the need for a DI (direct
injection box). This function affects only the phone jack input.
o [MIC/LINE] input jacks (Channels 1 – 4)
For connecting microphones, guitars, electronic musical instruments
or audio devices. These are compatible with both XLR and phone
plugs.

program. The last value used with each effect program is saved.
NOTE
If desired, a single channel’s [LINE] and [MIC] jacks can be used together
at the same time. But note that the levels cannot be adjusted indepen-
dently. The stereo mini jack has priority for channel 11/12 [LINE] input jack.
NOTE
When you change to a different effect type, the mixer automatically
restores the value that was previously used with the newly selected effect
(regardless of the current position of the FX RTN [PARAMETER] control).
!3 FX RTN [AUX1] send control
For adjusting the level of the signal sent from the built-in effect unit to
the AUX1 bus.
!4 FX RTN [LEVEL] control
Signal indicator
For adjusting the level of the effect sent from the built-in effect unit to
