SELF CHECK AND INSPECTIONS
PREPARATIONS1. If no specific frequency is required, set the test frequency at 1 kHz.2. Before turning the [POWER] switch on, set the Idling Adjustment Volume (VR201, 1 k ohms) on the MAIN circuit
board at minimum.3. Before turning the [POWER] switch on, set all the knobs at the center position.
SELF CHECK MODESET-UP: While pressing the SW2 switch on the DM circuit board, turn the [POWER] switch on. The self check mode
program will be started.
0. LED CheckWhen the DG60-112 enters the self check mode, the LED check is started and the LEDs light automatically as thecheck follows the circular sequence below, while pressing the SW2 switch.
When the SW2 switch on the DM circuit board is released, the check will proceed to the next SW check after allLEDs light-up and the LED check is finished.
1. SW CheckCHANNEL SELECT SWITCH (A/B)
If the channel select switch is turned on (selected B ch) when a plug is not inserted into the CH SELECT jack(JK5), A ch LED will light.
CH SELECT (JK5)When a plug is inserted into the CH SELECT jack (JK5), the channel select function will go out and the A chLED will light. Removing the plug will make the A ch LED go out.
REVERB (JK4)When a plug is inserted into the REVERB jack (JK4), B ch LED will light. Removing the plug will make the B chLED go out.
SP MUTE (SW3)When the SP MUTE switch (SW3) is pressed, both the A ch and B ch LEDs will go out.
When the SW2 switch on the DM circuit board is pressed, the check will proceed to the next Volume check after allthe LEDs light-up and the SW check is finished.
2. Volume CheckThis volume check can be tested in the order below from 1 to 18.
1. A ch AMP SELECT (CN3–1 pin)2. A ch GAIN (CN3–2 pin)3. A ch MASTER (CN3–3 pin)4. A ch TREBLE (CN3–4 pin)5. A ch HIGH MID (CN3–5 pin)6. A ch LOW MID (CN3–6 pin)7. A ch BASS (CN3–7 pin)8. A ch PRESENCE (CN3–8 pin)9. A ch REVERB (CN3–9 pin)10. B ch AMP SELECT (CN4–1 pin)11. B ch GAIN (CN4–2 pin)12. B ch MASTER (CN4–3 pin)13. B ch TREBLE (CN4–4 pin)14. B ch HIGH MID (CN4–5 pin)15. B ch LOW MID (CN4–6 pin)16. B ch BASS (CN4–7 pin)17. B ch PRESENCE (CN4–8 pin)18. B ch REVERB (CN4–9 pin)
all LEDs on all LEDs off A ch LED on B ch LED on all LEDs off
DG60-112

When fully turning the check volume knob counterclockwise, the A ch LED (CN5–2 pin) will light; when fullyturning it clockwise, the B ch LED (CN5–3) will light. If the volume is no good, both the A ch and B ch LEDs(CN5–2, 3 pin) will light to indicate the error.Each press of the switch (SW2) will proceed to the next volume check after lighting both the A ch and B ch LEDs.Press the switch (SW2) after finishing the volume checks to proceed to the next Sound Check. When cancelling atest during a check, hold down on the switch (SW2) for a few seconds. The A ch and B ch LEDs will then go out, re-light, then the test will be cancelled.
3. Sound Check (Power Amplifier Adjustment)
3-1 Idling Adjustment1) Before turning the [POWER] switch on, set the Idling Adjustment Volume (VR201, 1 k ohms) on the MAIN
circuit board at minimum.2) Press the channel select switch and select the B ch.3) Connect an 8 ohm load between the speaker terminals BT202 and BT203.4) Set the B ch MASTER volume at minimum.5) After turning the POWER switch on, adjust the Idling Adjustment Volume (VR201) to set the voltage of the
terminals of the CN204 or R252 at 5 mV +/- 1 mV.
3-2 Sound CheckThis Sound Check is performed by using a signal that goes through the following circuits: the analog circuit, theA/D converter, the DSP-3 and the D/A converter.This check should be performed after the VOLUME check has finished and when both the A ch and B ch LEDs(CN5–2, 3) are lit.
* 0 dBm = 0.775 VWhen Sound Check is completed, turn the [POWER] switch off to quit the self check mode.
