[Test content]
Apply the looped signals from PHONES to qSNARE–
iKICK/9 and check for the following.
• The signal is inputted to CPU at the correct level.
• There is no signal leakage to another input.
• The attenuation value of the waveform is correct.
* The output waveform from PHONES is sine wave (4kHz,
+4dBu (3.5Vpp, load 10kΩ).

Press the [SAVE/ENTER] key to execute the test.
Execute C-09.R.Encoder test. If its result is OK, testing is started
