Precautions
e Be sure to provide adequate ventilation for the unit on all sides, particularly when it is placed in an audio rack. If
ventilation is blocked, the unit may overheat and not operate properly. Also, be sure to use the unit in a horizontal
position. Never place the unit on its side or on a slanted surface since this could result in a malfunction.
¢ If the unit is placed near a TV or other tuner, it may cause reception inteference resulting in some noise in the TV
tuner output. In this case, place the TV or other tuner in a far distance from this unit.

@ ON/STAND BY switch and STAND BY indicator
Press to switch ON, and press a second time to switch
to STAND BY mode. The STAND BY indicator comes on
at the STAND BY mode. While this indicator is on, this
unit can be switched ON by the ON/STAND BY switch on
the front panel or the remote control unit. This indicator
flashes when receiving signals from the remote control unit
and this unit operates.

er (XR-9018/9028), CD auto changer (XR-9058),
and turntable (SR-5638), the whole system can be

LINE
Signals to which DSP effect is ap-
plied for FRONT and REAR are
output from the <ADAPTOR>
OUT terminals (DSP is not effec-
tive when it is switched off). Ac-
cording to preference, connect
these terminals to those of a Caution
graphic equalizer to obtain various
tones or to those of a power am-
plifier using this unit as a pre-
amplifier.
® Speaker positions and connections
Ensure that speaker polarity is matched with amplifi-
er polarity by connecting plus (+) speaker cables to
red speaker terminals, and minus (—) speaker cables
to black speaker terminals. Use speakers with im-
pedance in the 6 to 16 ohms range.
Expose about 10mm of lead
Twist the lead wires
firmly together, insert my
into the speaker ter-
minal aperture, and
then tighten firmly by
turning clockwise.
= Speaker positions
Since this unit is a 4-channel amplifier designed
to drive independent front and rear speakers,
position the speakers as indicated in the illus-
tration upon to get the most effective results
with natural soundfield playback. Although good
results can be obtained even when small mini
speakers are used as the rear speakers, adjust
the rear speaker volume etc to match the acous-
tic conditions of the listening room.
Remove the shorting pins from the <ADAPTOR > terminals only when using those
terminals. But do not plug these pins into any other terminal under any circumstances
(since this can result in failure). lf not using the <ADAPTOR> terminals, make sure
that the shorting pins are plugged in as shown in the diagram. Incorrect insertion
may prevent output of sound.

e Any 34 keys framed by the gray line
can learn signals from your remote
control units in each position of the
TRANSMIT mode switch.
¢ See the next page for learning.
PROGRAMMABLE PRESET keys
¢ These 13 keys (under the names
of PHONO, TUNER, TAPE A, and
TAPE B) are available for learning;
however, they are preset with the
following functions at the factory.
¢ When TOSHIBA's optional com-
ponents, such as_ turntable
(SR-5638), tuner (ST-5528/
5538), and tape deck (PC-5858),
are connected to this unit at
<SYSTEM CONTROL>, these
components can be operated in
any position of the TRANSMIT
mode switch.
e The learning method is the same
as for PROGRAMMABLE keys.
* To initialize keys which have
learned signals, press the Reset
button in the battery compart-
ment. Note that in this case all
the memory except that of the
preset keys is erased.
e After initialization, these keys
operate for the above compo-
nents. For the tuner TUNING key,
it selects preset bands in se-
quence. For details, refer to each
component's owner's manual.
Note:
Since some optional components to
be connected for system control are
not available in some areas, check
their availability at the authorized
TOSHIBA service station in your
area.
MASTER VOLUME keys
These keys operate the MASTER
VOLUME control on the front panel
Press [Al to increase volume and [V] to
decrease it.

ADJUSTMENTS
The adjustment procedures for this IC using an oscilloscope are described below.
TD6704P (ANALOG/DIGITAL) ADJUSTMENT
1. Make the input signal of the left and right channels 0 volt (in source pause or input open status), and rotate the semi-fixed
potentiometers R623 (5k ohms) and R624 (5k ohms) to adjust the output voltage at the test points TP4 (Q606 Pin (7)) and TP3
(Q607 Pin (27)) for 4.0 volts. Refer to Figure A.
2. Apply trigger to the test point TP2 (Q607 Pin (7)) and observe the TP1 (Q607 Pin (10). The oscillator indicates as shown on the
(a) and (b) of Figure B, rotate R625 so that the “H” levels become as small as possible (Figure B, (c)). If there is unbalance in
the level between the right channel and left channel as shown figure B (d), slightly rotate R623 and R624 to balance the level
between 2 channels and then repeat the above procedures.

LIGHT UP SENSITIVITY ADJUSTMENT
At the factory, the sensitivity of detector circuit is adjusted so that the LED starts to illuminate when the voltage becomes 500mV
at the Dolby test point. The adjustment procedures used in the factory are as follows:
(1) Take out the DSP unit from the case. Pull out the plastic rivet holing the PC board and unfold the double-folded PC board.
(2) Feed sine wave of 1kHz 350mV from a signal generator to the CD analog input terminal (left or right only).
(3) Apply the power to XB-1000 and set to the CD analog input, Dolby surround DSP mode.
(4) Rotate the INPUT LEVEL potentiometer so that the signal level becomes 500mV rms at Dolby test point (Q604 Pin (2)).
(5) Rotate R765 (located beside the microprocessor) on the PC board so that the “OVER” LED just comes on.

PCM56P (DIGITAL/ANALOG) ADJUSTMENT
The followings explain the adjustment procedures of D/A converter.
(1) Remove the DSP unit from the main unit’s chassis. Pull out the plastic rivet holding the PC board and unfold thePC board. In
this process, keep all the connection cables for input and output connected.
(2) Place the unit to the Digital In mode.
(3) Reproduce the test signal of OdB (against full-scale), for example 1th track of YEDS7, by a CD player having the digital out fea-
ture and feed it-to the this unit in digital signal.
(4) Adjust R643 and R644 so that the signal distortion rate for the left and right channels at the output terminal J7(1 of the DSP
unit becomes minimum.
