Input the signal at 15kHz, Turn EQ HIGN knob of the relating channel clockwise to the max (+15), the output is +15dBu( 3dB), then turn

3、 EQ HIGH knob of the relating channel counter-clockwise to the min. (-15), the output is 15dBu( 3dB); 4. test DSP a. Input the signal from MIC1, output the signal from MAIN MIX OUTPUT, turn AUX RTN2(DFX)clockwise to the MAX, turn PRESETS and VARATIONS knobs, the signal will be processed by DSP, if t

4、he level of the signal is over-high, PEAK LED will be illuminated to red, press DFX MUTE button, Bypass the signal, press the footswitch, which is connected to DFX FOOSWITCH, the signal will get out of BYPASS. b. Input the signal from MIC 1 to MIC 4, output the signal from AUX SEND S1, turn AUX 2 /D

5、FX TO AUX 1 counter-clockwise to the MAX., turn PRESET and VARATIONS knobs, the signal will be processed by DSP. (do not need to test L6 with this step) 5. Sampling test Connecting L 6 to a power amplifier and speakers, listening to the sound, no noise is OK. Company preset: turn all volume knobs to
