5.3 to store a Program: in Play or Edit mode, press the VALUE knob. The display will flash the current program 

number. Use the Program Up and Down buttons, VALUE knob or the optical footswitches to select the 
program number where the current program will be stored. Press the VALUE knob again to store the 
program in the selected place. 

6 “DRIVE” knob: same functions as the DRIVE of DIST 
7. BASS: used to adjust the amount of bass in the current program. 
8. “TREBLE”: used to adjust the amount of treble in the current program. 
9. MASTER VOLUME knob: the MASTER VOLUME knob controls the overall volume of the audio signal that 

is output to the speaker, the HEADPHONES jack and the STEREO LINK OUTPUT on the rear panel. 
This value is not stored with a program. 

10. HEADPHONES jack: plug headphones into this jack using a standard 1/4” stereo phone plug. It is analog 

stereo signal output. The internal speaker, STEREO LINK OUTPUT and SPEAKER OUTPUT are 
automatically disabled when headphones are used

FOOT SWITCH jack. Connect to standard footswitches to use for incrementing and decrementing program 
numbers. The footswitches work in the same way as the Program Up and Program Down buttons. 

2.

 

EXPRESSION PEDAL: connect to “EXP PEDAL” input signal. It is balanced input. Connected to B50K 
potentiometer to control DSP. 

3.

 

STEREO LINK OUTPUT: is a mono analog output signal, it can use for route the right channel signal to 
outside equipment 

4.

 

SPEAKER OUTPUT: Connects to an external speaker. When it is applied internal speaker will be disconnect. 

5.
