DIGITAL EFFECT section

 

This section allows you to turn the built-in digital 
effect on/off and to select the effect type.

 

6

 

Effect select switch and indicator

 

Select the effect type for the built-in digital effect.

The indicator of the selected effect type lights up.

 

7

 

DIGITAL EFFECT ON switch and indicator

 

When this switch is on (pressed), the indicator 
lights up and the built-in digital effect can be 
used. In that case, the signal processed by the dig-
ital effect will be sent to the MAIN/MONITOR 
bus. The mix level of the effect sound is adjusted 
by the EFFECT RTN control of the MAIN and 
MONITOR sections.

 

 

MONITOR section

 

This section allows you to adjust the tone and 
volume of the MONITOR bus, and specify the 
mix level of the built-in effect and the external 
input signals.

 

8

 

Graphic equalizer

 

This is a 7-band graphic equalizer that allows you 
to adjust the frequency response of the MONI-
TOR bus signal, providing a maximum of ±12 dB 
of cut/boost for each frequency band. You can use 
these sliders to reduce the level of frequency 
bands at which feedback easily occurs. Frequency 
response is flat when a slider is in the center posi-
tion. Moving a slider in the positive direction will 
boost, and in the negative direction will cut.

This graphic equalizer affects both the MONI-
TOR bus signal that is output to the speakers and 
the line level signal which is output from the 
MONITOR jack (input/output panel 

 

6

 

).

 

9

 

EFFECT RTN control

 

This controls the level of the effect sound which 
is returned from the built-in digital effect to the 
MONITOR bus.

 

0

 

TAPE IN control

 

This  controls the level of the signal routed from 
the TAPE IN jack to the MONITOR bus.

 

A

 

MASTER control

 

This adjusts the final level of the MONITOR bus. 
It affects both the MONITOR bus signal which is 
output to the speakers and the line level signal 
which is output to the MONITOR jack (input/
output panel 

 

6

 

).

 

B

 

Peak level indicator

 

This indicator allows you to monitor the level of 
the signal which is output from the MONITOR 
jack (input/output panel 

 

6

 

).
