Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessaryto readjust it.Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.
• Automatic adjustment item1. Focus offset (Fig. 16-2)2. Tracking offset (Fig. 16-3)3. E/F balance (tracking error balance) (Fig. 16-4)4. RF level AGC function (HF level: constant)5. RF level automatic follow-up of the tracking gain
This automatic adjustment is performed each time a disc is changed. Therefore, each disc is played back using the optimal settings.

EXPLANATION OF DOLBY SURROUND PRO LOGIC AND EVALUATION METHOD
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←
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 inMUTE state. The SP output is cut.
• In the normal mode of Pro Logic ON mode the amplifiers forC-ch and S-ch are in operative state, so that the SP outputappears.
• In the Phantom mode of Pro Logic ON mode the amplifier forC-ch is in MUTE state, so that the SP output is cut. Theamplifier for S-ch (surround) is in operative state, so that theSP output appears
• State of element output and terminal output in specific mode
Relation between VIDEO IN input and output in Pro LogicON state(1) L-ch/R-ch same phase input into VIDEO IN input jack in
VIDEO Function mode
Output point Normal mode
Output point Phantom mode
(2) L-ch/R-ch reverse phase input into VIDEO IN input jack inVIDEO Function mode
(Reverse phase: Phase difference between L and R is 180°)
Output point Normal mode
SP out L-ch Almost no output (only omitting component)(TMV01) R-ch Almost no output (only omitting component)
(TMX11) SP out C-ch Almost no output (only omitting component)
(TMX11) SP out S-ch Input signal is output.
Output point Phantom mode
SP out L-ch Almost no output (only omitting component)(TMV01) R-ch Almost no output (only omitting component)
(TMX11) SP out C-ch SP cut, no output
(TMX11) SP out S-ch Input signal is output.
• Accordingly, if you want to output signal waveform to C-ch SPout, give the same phase input into L-ch/R-ch INPUT in thePro Logic Normal mode.
If one of channels receives input, C-ch does not output. OnlyL-ch or R-ch outputs.
• If you want to output signal waveform to S-ch SP out, you canuse 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 andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.
• Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As toelectrolytic capacitor, the expression “capacitance/withstandvoltage” 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 thismodel are subject to change for improvement without priornotice.
