[Test content]
Check that the signals inputted from AUX IN are being
outputted from PHONES (L/ R) as correct ones.
[Test method]
Input the following sine wave (“Check item” below) into
AUX IN (L/ R). Insert the standard stereo phone plug
into PHONES (L/ R) and measure the frequency, output
waveform level, and distortion factor of each output.
(Maximize PHONES VR and AUXIN VR.)
[Check item]
· Input a sine wave of – 20 dBM, 1kHz into AUX IN (L).
(Connect AUX IN (R) to ground and set AUX IN and
PHONES volume to MAX.)
PHONES (L): +1.0 +/- 2 dBm, distortion factor of 0.5 %
or less (Load of 33
Ω
)

C- 95. 64ch OUT
[Initial indication]
[Test content]
Check that 64 sound channel is producing sounds
correctly with 1 ~ 32ch producing sounds from
OUTPUT (L/MONO) and 33 ~ 64ch producing sounds
from OUTPUT (R).
[Test method]
If the [ENTER/ YES] key is pressed, the LCD indicates
“Sounding” for approx. 0.3 seconds and “Silent” for
approx. 0.1 second. This is repeated 32 times. Set the
MAIN OUT volume to MAX.
XX: Number of the channel currently producing sounds
Check by auditory sense that 64 sound is produced
correctly. Also check that the output wave is a correct
since wave. (Lch = 1 kHz, Rch = 700 Hz)
[Indication of judgment result]
None
[Content of FAIL judgment]
None
[Completing the test]
The test will proceed to the next one automatically.
