T14: 1 KHz OUTPUT L
(Test Code: A00E00)
[First indication]
Press [ENTER] 14 : OUTPUT-L
TEST
MOTIF XS Test Program
[Test contents]
Check that normal signals are output from the [OUTPUT
L/MONO], [ASSIGNABLE OUTPUT L] and [PHONES(L)]
jacks.
Operate the [MASTER VOLUME] to check that volume
from the [OUTPUT L/MONO] is changed smoothly.
(Play the sine wave of the Wave ROM from the Master side
SWP51(DM: IC010) to output from the speci
fi ed output jack.)
[Test method]
Connect measuring instruments to each of the [OUTPUT L/
MONO], [OUTPUT R], [ASSIGNABLE OUTPUT L, R] and
[PHONES(L),(R)] jacks. Check frequency, output waveform,
output level of each output with a frequency counter, oscilloscope
and level meter (with a JIS-C
fi lter).
Set the [MASTER VOLUME] at the maximum.
The LCD displays as follows when a sound is output.
