2、are series of innovative design power amplifiers. This series work under highstability with great power supply in just 2-rack spaces. Airflow is from back to front panel to keep in a nice aircirculation inside the Rack. The automatic fan, which affects the temperature of machine includes variouskind

3、s of speed, therefore, this low-noise fan makes a good result in cooling the heat from machines. MISTRALamplifiers include 2 independent channels with separate protection system and power supply. Theindependent protection system avoids opening circuit, short, and wrong loading or over-heating. The s

4、pecial-designed protective system applies automatically restarting functions upon the default status and then goesback to normal. All electronic inputs equip standard power connectors. And all inputs are electronic balanced,with hi-quality transformer, MISTRAL amplifiers provide an outstanding perfo

Set LIMITER and BRIDGE switches at the position of OFF, turn the VRs of CH1 and CH2 to maximum, then turn on the power switch, the power LED will be illuminated (blue), OPERATING/PROTECTION LED is illuminated to be red at first, then bec

44、ome green after 2-5 seconds, the fan will be running. When you use the solder gun to test the position of R1-3 (R2-3), the fan should be accelerated.b. Without any signal input, adjust R1-20, R1-21 (R2-20, R2-21) backwards first,make sure the arrow is facing to the rear panel, then adjust forwards,

45、make thearrow is facing to the front panel, then test the DC voltage across the TP1-6 (TP2-6)and the ground, adjusting R1-16 (R2-16), the voltage of R1-16 (R2-16) should be 138mV 2mV.c. Connect a load of 4 to each channel, input the signal of 4dBu , then adjust R1-20, R1-21 (R2-20, R2-21) , make sur

46、e that the crossover distortion reaches its peak.d. Turn off the input signal, the standby power consumption should be 75105W.e. Input the signal of 1KHz/3dB to CH1 and CH2, then connect a 4load to eachinput channel, CH1 and CH2. Each output should be 69.2V, the distortion shouldbe 1%.f. Turn the po

47、wer switch of the LIMITER to ON position. Set the input to 1KHz/+10dB the clip should be lit up and the signal will not boost.g. Use the solder gun to connect R1-50 and R2-50 for about 10 seconds separately.When the outputs of CH1 and CH2 are cut off, OPERATING/PROTECTION LEDwill be illuminated (red

48、).h. Press BRIDGE switch, input the signal of 1KHz/4dB to CH1, connect a 8 loadto the bridge output, the output should be more than 133.5V, the distortion shouldbe less than 0.7%.i. Adjust volume VR to the minimum, turn LIMITER switch to the position of ON.Set CH1 and CH2 in short circuit, then adju

49、st the VR volume to the maximum, theLED for LIMITER on the panel will be illuminated, the consumption power shouldbe less than 100W.j. When the output reaches the MAX, set the output in short circuit, the consumptionpower should be less than 700W.The finished-product test procedurea. Set LIMITER and

50、 BRIDGE switches at the position of OFF, turn the VRs of CH1 and CH2 to maximum, then turn on the power switch on the panel, the power LED will be illuminated (blue), OPERATING/PROTECTION LED is illuminated to be red at first, then become green after 2-5 seconds, the fan will be running. CLICK will
