Check method and standard
1. Set the INPUT selector to the ANALOG posi-
tion.
2. Apply a 1kHz, 500mVrms analog signal to the
LINE IN (ANALOG).
3. Demodulate the digital signal of DIGITAL OUT
(COAXIAL) to analog.
4. Adjusting the REC LEVEL control knob, check
that the demodulated signal level can be set
to 1Vrms. (The level meter should indicate -
6dB on display.)
5. At this time, check that the REC LEVEL con-
trol knob is close to the 12 o’clock position.
6. Check that the distortion factor is 0.03% or less.
7. Check that the S/N is 80dB or more. (Input
shorted, REC LEVEL max.)
8. Check that the frequency response (at 20Hz
and 20kHz) is 0
±
1.5dB.

Check method and standard
1. Cancel the audio measurement mode.
2. Turn on the power. (In normal mode)
3. Load the CD test disc (YEDS-18: TX911730).
4. Play track 2 (1kHz, 0dB).
5. Check that the output level of LINE OUT (ANA-
LOG) is 2
±
0.5Vrms.
6. Check that the distortion factor (1kHz) is 0.01%
or less.
7. Play tracks 3 (20Hz) and 6 (20kHz) and check
that the frequency response is 0
±
1.5dB.
8. Play track 7 and check that S/N is 100dB or
more.
