Adjustment of dc offset
a) Set up horizontally.
b) Trim resistance of R5521,5522,5621,5622 are adjusted center position before POWER ON.
c) Set the voltages at SP OUT Lch±/SP OUT Rch± to 0±50mV by adjusting R5521/R5522, under the condition
of no input(VOL:0) and no load, immediately after POWER ON.
d) Set the voltages at SP OUT Lch±/SP OUT Rch± to 0±10mV by adjusting R5621/R5622 just minutes after c.
e) Re-set the voltages at SP OUT Lch±/SP OUT Rch± to ±10mV by adjusting R5621/R5622 after 10 minutes of heat running.TEST:4-01
Adjustment of idling current
a) Set R6553/R6554 to minimum position before POWER ON.
b) Set the voltages at P6505A and P6506A to 25.0mV±5mV by adjusting R6553/R6554, under the condition of
no input and no load, immediately after POWER ON.
c) Re-adjust by following procedure after 10 minutes of heat running.
L/R
Below 25mV
25mV+2mV
Between 25-30mV
Leave it as it is.
Over 30mV
30mV-2mV
Equip series 1/4W 100-ohm resisters near the terminal respectively
in the each poles of the jig used for P6505A,P6506A terminals.
Please adjust before Idling current adjusting.If you adjust DC offcet, readjust Idling current too.
