8. CH6/PHONE SELECTOR
This switch is for select the CH6 or PHONO.
NOTE:When switch selected the PHONO, the input gain volume of CH6 can’t adjusting.
9. INPUT GAIN CONTROL
According to the input signal source, adjust adequately these gain controls not to exceed input sen-
sitivity. When the input level exceed the rated sensitivity, output signal of amplifier could be distorted
and overloaded. Gain adjusting range of these volumes are 50dB, and general position of the vol-
ume is as following.
MIC(Microphone)..................................................-50~-70dB
MIC ATT(Electric Guitar)......................................-30~-50dB
AUX(Deck, Tuner, etc).........................................-20~-30dB
10. (OPTION)
These are input terminals which is designed electrical balanced circuitry. Optionally, the type of ter-
minals,XLR female jack, phone jack, screw terminals and RCA jack are provided. And transformer
balanced circuitary is optional per buyer’s order.
11. PHONO INPUT TERMINAL
This jack is for the input of turntable of magnetic cartridge, and the signal is controlled by the volume.
12. TELEPHONE IN TERMINAL
These terminals are to be connected to telephone exchange system for paging.
NOTE:When there are paging signal through this terminal, all other input signals except AMP IN are
muted.
13. EXT MUTE
When these two terminals are shorted, the signals from CH3 to CH6, turner and turntable are muted,
and the signals from CH1, CH2, LINK IN and CHIME are not muted. You can use these terminal
for remote control.
14. EXT CHIME
When these terminals are shorted, the circuitary of 4 tone chime is activated. Also, you can use th-
ese terminal for remote control.
15. FUSE HOLDERS (AC) OPTION
These fuse holders contaic AC fuses, replaces them with same type fuse when they are blownout.
If they continuously blow, stop replacing fuses and refer servicing to qualified personnel.
16. IMPEDANCE SELECTOR SWITCH
This switch is for selecting the high impedance.
