20 ASSIGNABLE OUT-3
20: ASSIGNABLE OUT-3
Insert the appropriate phone plugs into the ASSIGNABLE OUT-3
terminal. Check the output wave form and the output level of each
output by using an oscilloscope, an AC voltmeter (with JIS-C filter)
and a distortion factor meter.
ASSIGNABLE OUT-3: 1 kHz +/- 1 Hz, sine wave, less than 0.5%
ASSIGNABLE OUT-4: less than -70 dBm (10 k ohm load)
While sounding, the LCD shows as below.
