3. Actual use
Abnormal sound such as a touch of a voice coil or
fluttering sound should not be generated when sine
wave from 50 Hz to 20 KHz and music signals are
inputted.(Abnormal sound should not be generated
when 65 mV of 50 Hz to 20 KHz sweep sine wave
is inputted to LINE 2 jack).
The power amplifier output should be below clipping
level.
Moreover, when each knob is turned, volume and
quality of the sound should change smoothly.
Check the speaker is correctly connected by the
phase checker. (Normal Phase)
