1. INTRODUCTION

Innovative design and high stability power amplifier

Fan-cooled AB class high power amplifier in 19", 2U size

8

independent channels with separate protection system

DC, infrasonic, overheat & short circuit protection

Smart-designed protection system for auto re-operation after fault

Parallel-input: channel 1 to channel 2, channel 3 to channel 4, channel 5 to channel 6, channel 7 to channel 8

Allowing selection of Stereo, Bridge or parallel operation

Ultra low-noise and hum
High-pass filter , allow selection of flat, 35 Hz or 75Hz, protect speakers and prevent speaker transformer saturation

with minimal effect on program material.

DIP switch control for clip limit, high-pass filter, bridge-mono stereo selections

AUTO variable- speed-low-noise fans ensure high reliability even under demanding conditions.

Detachable Euroblock: " Barrier strip" input connectors.

Rugged amplifier in a strong, compact chassis

The Finished Products Test

7. TEST PROCEDURE

- 18 -

Test instruments

1). VF analyzer

2). Multimeter

3). Frequency transformer

4). 4Ω（1000W）load resistance*2PCS

5). 8Ω（1000W）load resistance*2PCS

6). Oscilloscope

7). AC protector

1. Initialize:

1) The Power switch turns OFF.

2) Connect the Power cord to AC protector.

3) The Output of frequency converter is 230V/50Hz; turn off all the push

switches.

2. Turn on the Power switch, the blue power LED and PROT LED will

illuminate, and other LEDs don’t illuminate, 2~5 seconds after turning on the

unit, the PROT LED will extinguish.

3. Mono Channel Output Test: With 4Ω loads at the Output terminal, input

1KHz/0.6dBu±0.25dBu signal, then rotate corresponding VRs to maximum,

the output will reach to 207W±5W, at this time, the distortion should be less

than 1%. The S/N of CH1 should be higher than 85dB, and the S/N of other

channels should be higher than 90dB. When rotating the VR from minimum

to maximum, with the increase of VR, the SIG LED will become

well-illuminated, when the power is full, the CLIP LED illuminates slightly,

and the output waveform will appear cut-off distortion.

4. LIMITER Test: Go on the step 3, when the “1”of push switch is at the “ON”

position, the CLIP LED extinguishes, the output power will drop to

190W±5W, the distortion should be less than 1%(When test the LIMIT CLIP,

set “1”(on push switch)of the CH1/CH3/CH5/CH7 to “ON” position, set

“10”(on push switch)of CH2/CH4/CH6/CH8 to “ON” position). When doing

the third and fourth step test, the post can not appear protection

phenomenon.

5. Short Circuit Protection Test: When full power output, the short circuit output

terminal and the post relay should open within 1~ 7 seconds and also should

close 1~3 seconds later, the PROT LED and CLIP LED will change with the

relay from brightly to extinguish.

6. Noise Test: Connect a 4Ω load, and set the VR to maximum, the Hum or

Noise<2mV.

- 19 -

7. Filter Test: Set the push switches to FILTER ON and 75Hz FILTER positions

(“2” turn on and “3” turn off), set the TIME/DIV knobs of oscilloscope to 10ms

position, and set the VOLTS/DIV knobs to 0.5mV position. Input 125Hz/0dB

signal, adjust VR of the test fixture and input signal, make sure the output is

5dB, and then adjust the input signal to 75Hz, at this time, the output is

2dB±0.5dB. Recover the input signal to 125Hz/0dB; set push switch to 35

Hz FILTER position (“2” turn on and “3” turn off), adjust the output signal to

35Hz, the waveform Vp-p will become smaller, at this time, the output is

2dB±0.5dB. (When test the LIMIT CLIP, set “2” and “3”(on push switch)of

CH1/ CH3/CH5/CH7 to “ON” position, set “8” and “9”(on push switch)of

CH2,CH4,CH6,CH8 to “ON” position)

8. Other Mono channel output tests, please repeat step 3~7(CH2~CH8).

9. Parallel Connection Output Test: Input 1KHz/0dB signal from CH1 and CH3,

and CH2 and CH4 without input signal, then set VRs of CH2 and CH4 to

maximum, CH2 and CH4 have no output signal, turn on the”4”, ”5”, “6”of

push switches, PAR LED of the panel illuminates, rotate VRs of CH2 and

CH4, then can see the output waveform of CH2/CH4.

10. As for other parallel connection output tests(CH５~CH8)﹐please repeat the

step 8(Note: CH1 and CH2, CH3 and CH4, CH5 and CH6, CH7 and CH8

can parallel connection only).

11. Bridge Output Test: Set the “7”of push switch to “ON” position, the BRDG

LED of the panel lights up; the positive pole of load should be connected

with the positive pole of CH1 output terminal, the negative pole of load

should be connected to the positive pole of CH2 output terminal. Input 1

KHz/0dBu±0.2dBu signal from CH1, turn the VR of CH1 to maximum, VR

of CH2 to minimum, with 8Ω loads at the output terminal, the output should

be 410W±5W, and the distortion should be less than 1%.

12. Other bridge connection output tests(CH５~CH8) are the same with the

step 10(Note: CH1 and CH2, CH3 and CH4, CH5 and CH6, CH7 and CH8

can bridge connection only).

13. Fan Test: when turning on the unit, the fan will move around slowly, then

use the blower to heating R1_54, the fan will accelerate gradually till top

speed.

14. Cut off the input signal of all channels, the standby power consumption is

less than 85W.

15. Figure 1[When signal is 35Hz or 75Hz (switch”2”, ”3” and “8”, ”9”of the

push switch), the output range will decrease 3dBu±0.5dBu].
