2.40 Tuning Test Procedure
2.401 Power up the A6 while holding down soft button 4. Allow the unit to tune.
2.402 Once Oscillator/Filter tuning is finished, press the AUTO TUNE button. If the message
"ALL OK" appears on the upper left hand side of the Tuning Results page, then the unit
has passed tuning. Otherwise it has failed and you should continue on.
2.403 On the Tune results page, note which voices have something other than a "T" under their
columns. These are the voices that failed.
2.404 If a voice has failed VCA calibration (check the VCA row on the LCD), here's how to
tell which ASIC (Oscillator or Filter) has the problem:
a) Press soft button 3 (VCACAL).
b) Turn soft knob 7 (VOICE) to select the voice with the failing VCA.
c) Turn soft knob 8 (BAND) to see which VCA's failed for that voice.
d) VCAs 10-13 are in the Osc ASIC. The rest are in the Filter ASIC.
2.405 If a voice has failed AUTO calibration (check the AUTO row in the LCD), here's how to
tell which ASIC has the problem:
a) Press soft button 4 (OSCFRQ).
b) Turn soft knob 7 (VOICE) to select the voice that failed.
c) Turn soft knob 8 (BAND) to see which bands failed for that voice. If the failure is in
columns 1 or 2 (OSC), the the Osc ASIC is bad. If the failure is in columns 5 or 6
(FILT), then the Filter ASIC is bad.
