1. INPUT SENS knobs

These knobs are used to adjust the sensitivity of the

corresponding input jacks. Note that the INPUT SENS 1

knob also adjusts the sensitivity of the GUITAR/BASS jack.

2. PEAK indicators

These indicators allow you to confirm whether or not the

audio being input via the corresponding input jack is

distorting, and they do this by lighting up when the volume

reaches the distortion level of -6 dB. Use the INPUT SENS

knobs to adjust the input sensitivity in such a way that each

PEAK indicator only lights up occasionally when the

corresponding instrument is being played hard.

3. INPUT SELECT buttons

Use these buttons to select the input source (input jack) that

you wish to record. The indicater of the selected button will

light. If a lit INPUT SELECT button is pressed, it will turn off

and the corresponding input source(s) will be muted.

GUITAR/BASS:

This button is used to select either the GUITAR/BASS jack

for recording guitar or bass or the MIC 1 jack for recording

from a line-in or a microphone. Note that the GUITAR/BASS

jack will be selected automatically when an instrument is

connected to it.

* When either [GUITAR/BASS] or [VOCAL] is alone selected,

Adaptive Focus (AF) will be activated for recording.

What is AF method (Adaptive Focus method)?

Adaptive Focus is a unique Roland/BOSS technology

that allows the signal noise (S/N) ratios of AD and DA

converters to be vastly improved.

VOCAL:

This button is used to select the MIC 2 jack for recording

from a line-in or a microphone.

SIMUL:

SIMUL mode is activated by holding down [GUITAR/BASS]

and pressing [VOCAL]. In this condition, either the

GUITAR/BASS or the MIC 1 jack will be selected together

with the MIC 2 jack. In other words, two inputs will be

simultaneously selected. Note that the GUITAR/BASS jack

will be selected automatically when an instrument is

connected to it.

LINE:

This button is used to select the LINE jack. In this case, the

audio from the input source recorded on the track selected

for recording.

4. EFFECTS button

Use this button to select an insert effects’ patch (p. 118) and

to call up the screen for editing effects settings and the like.
