Parallel Connection: Follow up the third step, input 1 KHz 0dBu signal from CH1 or CH3, CH2 and CH4 disconnect the input signal, rotate the VRs of the CH2 and CH4 to maximum, CH2 and CH4 have no Output signals. Set the mode selector switch to the PARALLEL position

8、, rotate the VRs of CH2 and CH4, the SIG LED on the panel lights up, and also can see the output waveform of CH2/CH4. (Note: CH1 and CH2 should be paralleled connect only, the same as CH3 and CH4) 11. Bridge Output Test: Set the mode selector switch to the STEREOL position, the positive pole of the

9、load should be connected to the positive pole of CH1s output, and the negative pole of the load should be connected to the positive pole of CH2s output. Input1KHz 4.5dBu1dBu EIAJ signal from CH1, turn the VR of CH1 to maximum, the VR of CH2 to minimum, with 8? loads at the output, make sure the outp
