6. Issuing sound
Check the following items by listening.
ANALOG INPUT, ANALOG OUTPUT
CH1 (XLR), CH9 (XLR), CH16 (PHONE)
→
Inspect with STEREO OUT L/R (XLR).
EEFFECT function (DSP6 operation check)
Parameters
"Sound scene data": Use the file
name "JADE_01".
WORD CLOCK: INT48kHz
Input the music signal from ANALOG
INPUT CH1, recall scenes in order
from Scene 1 to Scene 4, and adjust
t h e [ G A I N ] k n o b s o t h a t t h e
STEREO METER OVER does not
light up for any scene.
Inspection : Recall Scene 1 (REVERB) and check
the signal with the headphones for at
least 15 seconds.
Judgment standard 1: The EFFECT sounds must
be output.
Judgment standard 2: The output must not include
any noise.
In the same manner, recall and inspect Scenes 2
through 16.
The Effect functions for Scenes 2 through 14 work
as follows.
Scene 2: SYMPHONIC
Scene 3: HQ PITCH
Scene 4: DYNAMIC FILTER
Scene 5: REVERB
Scene 6: SYMPHONIC
Scene 7: HQ PITCH
Scene 8: DYNAMIC FILTER
Scene 9: REVERB
Scene 10: SYMPHONIC
Scene 11: DYNAMIC FILTER
Scene 12: REVERB
Scene 13: SYMPHONIC
Scene 14: DYNAMIC FILTER
