NOTICE

(FOR CANADIAN MODEL ONLY)

Fuse symbols - (fast operating fuse) and/or - (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

REMARQUE

(POUR MODELE CANADIEN SEULEMENT)

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA .

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual.

Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual.

The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards.

Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

5. PCB PARTS LIST

NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.

• The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation.
• When ordering resistors, first convert resistance values into code form as shown in the following examples.

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J = 5% and K = 10% ).

$$ \begin{array}{l} 5 6 0 \Omega \quad \rightarrow \quad 5 6 \times 1 0 ^ {l} \quad \rightarrow \quad 5 6 1 \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots R D 1 / 4 P U [ 5 ] [ 6 ] [ 7 ] J \ 4 7 k \Omega \quad \rightarrow \quad 4 7 \times 1 0 ^ {3} \quad \rightarrow \quad 4 7 3 \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots R D I / 4 P U [ 4 ] [ 7 ] [ 3 ] J \ 0. 5 \Omega \rightarrow R 5 0 \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \ I \Omega \quad \rightarrow \quad I R O \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \ \end{array} $$

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

$$ 5. 6 2 k \Omega \rightarrow 5 6 2 \times 1 0 ^ {l} \rightarrow 5 6 2 1 \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots R N 1 / 4 P C [ 5 ] [ 6 ] [ 2 ] [ 1 ] F $$

8. PANEL FACILITIES AND SPECIFICATIONS

8.1 FRONT PANEL

① POWER (OFF/ON) switch
Press to turn power to the unit ON and OFF.
② STANDBY/ON switch/indicator

This is the switch for electric power.

This switch does not function unless the POWER OFF/

ON switch is set to ON.

ON : When set to the ON position, power is supplied and the unit becomes operational.

STANDBY : When set to the STANDBY position, the main power flow is cut and the unit is no longer fully operational. A minute flow of power feeds the unit to maintain operation readiness.

When the STANDBY indicator lights, the unit is in STANDBY.

NOTE:

When performing timer recording with this unit, be sure to set the POWER STANDBY/ON switch to ON.

③ Remote control sensor window
(4) VOLUME control

Use to adjust the volume level.

NOTE:

The TONE effect functions regardless of volume levels.

⑤ INPUT SELECTOR knob/indicators

Turn the knob clockwise or counterclockwise so that the indicator lights for your desired input source. Turning the knob clockwise causes the lit indicator to right. Turning counterclockwise causes it to left.

CD : For compact disc playback with a CD player.
TUNER : For AM or FM broadcast reception with a tuner.
PHONO : For record playback with a turntable.
LINE/SB : Set to this position when listening to a program from a component connected to the LINE/SURROUND BACK terminals.

TAPE 1/ : For playback with a cassette deck, CD recorder CD-R/MD or MD recorder connected to the TAPE 1/CD-R/ MD terminals.

⑥ TAPE 2 MONITOR button/indicator

Use when there is an adaptor component (graphic equalizer, etc.) or cassette deck connected to the TAPE 2 MONITOR terminals.

Off : Indicator goes out when not in use.
On : Indicator lights when using the adaptor component or listening to the cassette deck.

NOTE:

When no connections are made to the TAPE 2 MONITOR terminals, or when they are not in use, be sure to set this switch to the off position. (No sound will be heard if it is set to the on position.)

⑦ REC SELECTOR switch /indicator(For TAPE 1/CD-R/MD terminals)

This switch is used to select the recording source component. The signal from the selected component is output at the TAPE1/ CD-R/MD jacks for recording. To select a recording source component, press the REC SELECTOR switch so that the indicator of the desired source component lights up. When this switch is set to [TUNER] or [CD], the signal from the selected component can be recorded regardless of the input selector switch and TAPE2 MONITOR button settings.

CD : To record from the equipment connected to the CD terminals.

TUNER : To record from the equipment connected to the TUNER terminals.

SOURCE: To record from the equipment selected by the INPUT SELECTOR knob.

OFF : In this position, nothing from the REC terminals of TAPE 1/CD-R/MD is output. Set to this position when not recording; the cassette deck will be disconnected, improving sound quality.

NOTE:

The function selected using the INPUT SELECTOR knob will be recorded irrespective of the position of the REC SELECTOR switch (TAPE 2 MONITOR terminals).

⑧ BALANCE control

Should normally be left in the center position. Adjust the balance if the sound is louder from one of the speakers. If the right side is louder, turn toward the L (left) position and if the left side is louder, turn toward the R (right) position.

NOTE:

This control does not operate at DIRECT ON mode.

⑨ DIRECT/SB MODE button/indicator

Press and hold the button for more than 3 seconds to switch SB mode ON. (Volume indicator goes out)

Press and hold the button for more than 3 seconds again to switch SB mode OFF. (Volume indicator lights)

[DIRECT]

Use this button when you do not wish to pass the output from input terminal equipment through the various frequency adjusting circuits (BASS, TREBLE, BALANCE, LOUDNESS).

On : The indicator lights. The signals input through the input terminals are reproduced without passing through the various frequency adjusting circuits. This results in flat, pure sound which is a more faithful reproduction of the input source.

Off : The indicator goes out. The signal passes through the various frequency adjusting circuits.

[SB MODE]

The SB mode is a special mode in which the amplifier does not accept remote control except power ON/OFF (But all of the facilities can be controlled by manual as same as SB mode OFF.).

Fix the VOLUME control near the center position. In this mode, the set can be used as a power amplifier which amplifies the LINE/SURROUND BACK input (the function name is LINE/SB) with a input sensitivity of 1V.

For example, when the set is combined with one of Pioneer's Surround Back compatible receiver, the set can be used sa the Surround Back amplifier.

(For details, please refer to the instruction manual of the receiver.)

⑩ LOUDNESS button/indicator

Use when listening at low volume level.

On : The indicator lights. Boosts low and high frequencies to give added punch to playback even at low volume level.
Off : The indicator goes out. Should normally be left in this position.

NOTE:

This button does not operate at DIRECT ON mode.

TREBLE tone control

Use to adjust the high-frequency tone. The center position is the flat (normal) position. When turned to the right, the high-frequency tone is emphasized; when turned to the left, the high-frequency tone is de-emphasized.

NOTE:

This control does not operate at DIRECT ON mode.

BASS tone control

Use to adjust the low-frequency tone. The center position is the flat (normal) position. When turned to the right, the low-frequency tone is emphasized; when turned to the left, the low-frequency tone is de-emphasized.

NOTE:

This control does not operate at DIRECT ON mode.

13 PHONES jack

When using headphones, insert the plug into this jack.

14 SPEAKERS B (ON/OFF) button/indicator
