- Signal line
-
: Positive voltage line.
-
: CD playback signal line.
- The voltage value and waveforms are the reference voltage of this
measured by DC electronic voltmeter (high impedance) and
oscilloscope on the basis of GND terminal (DC IN Jack).
Accordingly, there may arise some errors in the voltage valuesand
waveforms depending upon the internal impedance of the tester
or measuring unit.
Measurement conditions:
*AC adaptor is used for power supply.
*Set the headphones VR(VR701) to center position(No.5).
*( ).......CD playback mode (Test disc 1kHz, L+R, 0dB)
