Test Procedure R2-20, R2-21 (CH2) make sure that the crossover distortion reaches its peak. (NOTE: maintain the power is

2、 230V). b. Set the output is short circuit, then adjust the LED for the LIMITER on the panel will be illuminated and the power consumption of the short circuit protection should be less than 485W. c. S/N: more than 88dB (A weighted is more than 100dB). d. Compressor function test: Turn on LIMITER sw

3、itch. Input a 1KHz / +10dB signal, the LIMITER LED is lit yellow and there is no clipped signal. e. Adjust the VR on front panel so that the output is :2V(4). The measured frequency response is more than 28Hz to 20 kHz+/-1dB (CH1/CH2) f. The output is more than 59V. i. Release the BRIDGE switch. Inp

4、ut a 1KHz signal into CH1(the level control of CH2 is turn to minimum). Connect a 8load with output terminal. Measure the bridged output voltage is 26 more than about 110V, the distortion is less than 1%. (This measurement shall be done in a minute). j. Turn off the input signal, the power consumpti
