Remark

1. When the above item are tested, short-circuit the row pin of 1, 2 pin of 313115-1(DSP board)CN1. After

test, remove the short circuit terminal.

2. Load connection: connect 4Ohm load to LOW output, and 8Ohm to Hi output.

3. Please check if bass BOOST circuit is normal. When the bass output is below 17V(ON LOAD),BOOST

circuit does not operate. When the bass output is above 17V(ON LOAD), BOOST circuit starts to operate.

Instruments required:

05-1

1) Sinusoidal signal generator, 5) Resistive load 4 Ω 800W,

2) Dual trace scope, with probe, 6) Resistive load 8 Ω 300W

3) Digital multimeter, 7) Pink noise from the GM “AUDIO CD”.

4) Variac 0-250 Vac,
P.S: Isolate the oscilloscope from earth and adjust the two traces on center of screen in GND

position.
Par. 1: visual check

- Make a visual check if the amplifier is perfectly done and especially verify:
a) the right value of fuses 8A 250V *4PCS
b) the right earth main connection on rear surface of front panel.
c) the insulation between the heat -sink and the case of TR1-15, IC1, 2, 3, 4 -then,

- Set the VOLUME control full clockwise.

Par. 2: connections

- Switch off the amplifier module,

- Set the ENCODER pot. on preset “NORMAL”.

- Connect the mains of amplifier module to VARIAC and set it at zero AC voltage.

- Connect the signal generator to Line Input (XLR socket) and set it at 1000Hz /-1.5dBu,.

- Connect the scope CH1 probe to amplifier low output and CH2 probe to amplifier high output-

Par. 3: Initial test

- Increase slowly the VARIAC voltage up to the nominal value (230Vac).

- Check the transformer sec. voltages with multimeter, (without signal on input):

F3-F4: 54V ±1.5Vac
F1-F2: 106V ±2Vac

- Check the +/-15Vdc supply on relative voltage regulator outputs (IC3 & IC4 devices).

- Switch ON the signal generator and verify that the output signals must be symmetrical referring

to GND, without detectable distortion and oscillation.

- Check that the low amplifier power output signal is 35V

RMS.

- -Check of SIGNAL led function, moving the volume potentiometer of amplifier;

when the output signal is <0.5V
when the output signal is > 0.5V

the led must be OFF,

peak

, the led must be GREEN lighted.

peak

-Then, rotate the volume potentiometer knob full clockwise

Par. 4: BOOSTER check of LOW Amplifier

- Connect alternatively the CH2 probe tip of scope on D2 cathode and D3 anode and

verify the following condit ions:
when the output signal is < 18Vrms the ±VCC1 voltage must remain linear at 35V,
when the output signal is > 18Vrms the ±VCC1 voltage must follow the output signal wave with
6Vdc offset, as shown in the following picture

TESTING PROCEDURE

05-2

- Switch ON the LOW ampli fier output to 4Ω load resistor and repeat the above booster check

verifying more or less the same ± VCC1 conditions and verify that the signal must be
symmetrical refer to GND, without detectable distortion and oscillation.
Increase the VOLUME pot. until a signal clipping.
Switch OFF the LOW amplifier out. to 4Ω load resistor

Par. 5: COMPRESSOR check of LOW amplifier

-Increase the input signal of 10 dB and check the out. signal to remain constant at 45V

if the Signal/Comp. led has changed the lighted colour, from GREEN to RED.
Par. 6: PTC function check on Heatsink

- Heat the PTC temperature sensor with a welder heated tip, in touch with its body, to verify this

protection works properly reducing the amplifier out. signal to few volts on time.
P.S. The check must be done with PTC, placed into heat -sink hole and silicon grease on.

Par. 7: Idle current setting of LOW amplifier

- Decrease to zero the signal generator, then, adjust VR1 trimmer to have a 5mV ±0,5mVdc

voltage drop across R24 & R26 (0,2 Ω) power resistors.
Par. 8: HIGH amplifier check .

- Select a 10KHz frequency with 1dB amplitude on signal generator.

- Connect CH2 probe tip of scope on HIGH amplifier output.

- Check that the high amplifier power output signal is 20+ 2V

PEAK

(18V

RMS

).

- Switch ON the HIGH amplifier output to 8Ω load resistor and increase the VOLUME pot. -

Verify the out. signal is limited to 22V

peak

.

- Switch OFF the HIGH amplifier output to 8Ω load resistor.

Part .9: Burn-in test

1. Connect the pink noise signal from CD player with the line input of speaker module.

2. Connect 4ohm 500W load resistor with the bass output.

3. Connect 8ohm 300W load resistor with the treble output.

4. Put band switch to the position 1, and then turn on the power switch of speaker module.

5. Adjust the pink noise level from CD player until SIGNAL/LIMIT indicators (red, green) sparkle.

6. Put the speaker modu le vertical and take the burn-in test for 2 hours.

Part .10: Final inspection

1. Check the electronic performance of the tested unit completely.

Note: remove the short-circuit connector of 313115-1 CN1 after test.
