What are the preparations for the Idle Current Adjustment?

There should be no load and no signal, the volume knob should be at the minimum position, and the speaker and power switches should be off. The power should be turned off some time previous to adjustment so that the interior of the unit has time to cool.

---

What are the steps for performing the Idle Current Adjustment?

1. Switch power on.
2. Adjust semi-fixed resistors R671 – R673 so that the voltage at the test points for the left, center and right channels (P671 – P673) is 4 mV.
3. Five minutes later, readjust to 8 mV.

What are the steps for performing the Auto Input Balance Adjustment?

1. Adjust the oscillator level so that the signal level as measured between test pin TP 1 and the ground TP on circuit board NAAF-4075 is 200 mV.
2. Adjust semi-fixed resistor VR 2 on circuit board NAAF-4075 so that the L and R output signal levels at test pin P075 on circuit board NAAF-4058 are as low as possible.
3. Adjust semi-fixed resistor VR 1 on circuit board NAAF-4075 so that the DC voltage at test pin TP 2 is 0 ± SmV.
4. Open test pin TP 3 on circuit board NAAF-4075 and confirm that the DC voltage at test pin TP 2 is O ± 5 m V.
5. Disconnect measuring equipment and remove test pins.

How to confirm the left, right, and center channel protection circuitry?

1. Adjust the volume knob so that the output voltage is 35 V peak for the above three channels when there is no load on the amplifier.
2. Connect a 2-ohm load and confirm that protection circuitry is not triggered.
3. Connect a 1-ohm load and confirm that the protection circuitrv is triggered.

---

How to confirm the rear channel protection circuitry?

1. Adjust the volume knob so that the output voltage is 25 V peak for the above channels when there is no load on the amplifier.
2. Connect a 3-ohm load and confirm that the protection circuitry is not triggered.
3. Connect a 1-ohm load and confirm that the protection circuitry is triggered.

---

What happens if the condition which triggered the protection circuitry continues?

The relay will turn on and off repeatedly. After the third minutes, it remains off.

---

How to check for DC voltage detection in the protection circuitry?

1. When there is no load on the amplifier, confirm that the protection circuitry is triggered when a DC voltage of +4 V is applied to test point P615.
2. Confirm that the protection circuitry is also triggered when a voltage of -4 V is applied.

How can the Acoustic Program be Preset?

The acoustic program can be called by pressing any button on the front panel or by using the remote control transmitter. In standby mode or recording standby mode, pressing one of these buttons switches power on and activates preset. Pressing any button once calls each button’s primary function (nos. 1 – 5), pressing the button twice calls the button’s secondary function (nos. 6 – 10). The same procedure is followed when using the remote control transmitter. For example, pressing button 1 /6 once calls it to 1, pressing it twice calls it to 6.

---

How to set the parameters?

Set the parameters (room size, tone controls, etc.) according to the present listening environment. Press the T button for advance; the • button for return. The parameters are indicated in the display. These can be changed with the parameter controller.

---

How to use the Input Selector?

These buttons select the inputs in forward or reverse sequence (CD, Phono, Tuner, Tape/DAT, Video-4, Video-3, Video-2, Video-1, DBS, VDP, CD, etc.).

---

How to use the Volume Control?

Turn the knob clockwise to increase the volume and counter-clockwise to reduce it. The volume level is indicated in the display on the front panel and on the screen display of the monitor-TV. Some static or acoustic interference may be heard at very low volume levels. To eliminate the sound, use the muting button of the remote control transmitter.

---

How to use the Power Switch?

Press to switch the power on. The standby/received indicator goes out. Press again to switch the power off. The standby/received indicator lights. The standby/received indicator also lights when a signal is received from the remote control transmitter.

---

What is the Standby mode?

In order to store the memory data and allow remote control transmitter operation, a small amount of current is supplied to the processor regardless of the power switch setting. This is termed the standby mode and its status is indicated by the standby/received indicator.
