IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard) Before returning the audio product to the user, perform the following safety checks.

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the audio product.

2. Inspect all protective devices such as insulating materials,

cabinet, terminal board, adjustment and compartment covers or shields, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for leakage

current in the following manner. * Plug the AC line cord directly into a 120 volt AC outlet. * Using two clip leads, connect a 1.5k ohm, 10 watt resistor

paralleled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as conduit or electrical ground connected to earth ground.

* Use a VTVM or VOM with 1000 ohm per volt, or higher,

sensitivity to measure the AC voltage drop across the resistor (See diagram).

* Connect the resistor connection to all exposed metal parts

having a return path to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.

METAL PARTS

All check must be repeated with the AC line cord plug connection reversed. Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the audio product to the owner.

CD SECTION

• Adjustment

Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely. Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is compensated inside the IC.)

* Focus offset adjustment * Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing 14-2

EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will be 0dB.)

* Focus gain adjustment * Tracking gain adjustment

EXPLANATION OF DOLBY SURROUND PRO LOGIC AND EVALUATION METHOD

Outline

• Namely, two speakers are connected in parallel to one amplifier.

• In the Pro Logic BYPASS mode the amplifier for C-ch (center

channel) and the amplifier for S-ch (surround channel) are in MUTE state. The SP output is cut.

• State of element output and terminal output in specific mode

State of set Dolby Pro Logic Dolby Pro Logic On mode Output point Bypass mode Normal mode Phantom mode

IC501 1 pin L-out Output enabled state Output enabled state Output enabled state

2 pin R-out Output enabled state Output enabled state Output enabled state IC501 3pin C-out No output Output enabled state No output IC501 9pin S-out No output Output enabled state Output enabled state SP OUT L-ch Output enabled state Output enabled state Output enabled state (SO901) R-ch Output enabled state Output enabled state Output enabled state SP OUT C-ch No output in MUTE (Q501) state Output enabled state No output in MUTE (Q501) state (SO901) SP OUT S-ch No output in MUTE (Q502) state Output enabled state Output enabled state (SO901)

Test tone output

• Pro Logic ON Normal mode Press the remote control TEST TONE button. →Output of only L-ch →Output of only C-ch

↑ ↓

Output of only S-ch ← Output of only R-ch The test tone (noise) is repeatedly output for output period (2 sec). In this case the following indication appears repeatedly. →TEST →L-ch →C-ch

↑ ↓

S-ch ← R-ch

• Pro Logic ON Phantom mode Press the remote control TEST TONE button. →Output of only L-ch →Output of only R-ch

↑ ↓

← Output of only S-ch The test tone (noise) is repeatedly output for output period (2 sec).

In this case the following indication appears repeatedly. →TEST → L-ch → R-ch ↑ ↓ ← S-ch←

Relation between VIDEO IN input and output in Pro Logic ON state

(1) L-ch/R-ch same phase input into VIDEO IN input jack in

VIDEO Function mode

Output point Normal mode

SP out L-ch Almost no output (only omitting component) (SO901) R-ch Almost no output (only omitting component)

(SO901) SP out C-ch (SO901) SP out S-ch

Input signal is output. Almost no output (only omitting component)

• In the normal mode of Pro Logic ON mode the amplifiers for C-ch and S-ch are in operative state, so that the SP output appears.

• In the Phantom mode of Pro Logic ON mode the amplifier for C-ch is in MUTE state, so that the SP output is cut. The amplifier for S-ch (surround) is in operative state, so that the SP output appears

Output point Phantom mode

SP out L-ch Input signal is output. (SO901) R-ch Input signal is output.

(SO901) SP out C-ch SP cut, no output (SO901) SP out S-ch

Almost no output (only omitting component)

(2) L-ch/R-ch reverse phase input into VIDEO IN input jack in

VIDEO Function mode

(Reverse phase: Phase difference between L and R is 180°)

Output point Normal mode

SP out L-ch (SO901) R-ch

(SO901) SP out C-ch (SO901) SP out S-ch Input signal is output.

Output point Phantom mode

SP out L-ch (SO901) R-ch

(SO901) SP out C-ch SP cut, no output (SO901) SP out S-ch Input signal is output.

Almost no output (only omitting component) Almost no output (only omitting component)

Almost no output (only omitting component)

Almost no output (only omitting component) Almost no output (only omitting component)

• Accordingly, if you want to output signal waveform to C-ch SP

out, give the same phase input into L-ch/R-ch INPUT in the Pro Logic Normal mode.

If one of channels receives input, C-ch does not output. Only

L-ch or R-ch outputs.

• If you want to output signal waveform to S-ch SP out, you can

use either Normal mode or Phantom mode. However, 180° reverse phase input must be given to L-ch/R-ch INPUT.

NOTES ON SCHEMATIC DIAGRAM

• Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.

• Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

• The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given.

1. In the tuner section,

( ) indicates AM < > indicates FM stereo

2. In the main section, a tape is being played back.

3. In the deck section, a tape is being played back.

( ) indicates the record state.

4. In the power section, a tape is being played back.

5. In the CD section, the CD is stopped.

• Parts marked with “ ” ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
