—— SPEAKER CONNECTIONS
—— RECORD PLAYING
Connecting a Speaker System
To connect a stereo speaker system:
1. Connect the (+) terminal of the speaker on vour
left (as viewed from the listening area) to the red
terminal marked (+) LEFT SYSTEM A on the
rear panel of the amplifier,
2. Connect the (—) or common terminal of the left
speaker to the black terminal marked (—) LEFT
SYSTEM A.
3. Connect the (+) terminal of the right speaker to
the red terminal marked (+) RIGHT SYSTEM A.
4. Connect the (—) or common terminal of the
right speaker to thé black terminal marked (—)
RIGHT SYSTEM A.
To connect to the terminals of the amplifier:
1. Depress the colored button, opening a hole in
the terminal.
2. Push the stripped end of lead wire in the hole
and release the button.
After connecting the speaker system, set the front
SPEAKERS switch to the A position.
Connecting an Additional Speaker
System
Following the same procedure indicated above, one
more speaker system can be connected to the
1000% by utilizing the speaker terminals SYSTEM
B. Each of the two systems can be operated inde-
pendently with the SPEAKERS switch on the front
panel. In addition, the speaker systems A and B
can be operated simultaneously when the SPEAK-
ERS is set to the A+B position.
If Speaker Polarities Are Not
Properly Matched...
If the polarities (+ and —) of the speakers and the
amplifier are not matched correctly, sound cancella-
tion at some [requencies or in some listening posi-
tion occurs. Particularly when listening to monau-
ral reproduction, this condition is noticeable by an
absence of sound at a point midway between right
and left speakers. If this situation occurs, check
the amplifier and speaker connections once again
and reverse the connections between the amplifier
and either right or left speaker.
Speaker Impedance
If you are connecting only one pair of speaker sys-
tems to the 1000X, they may have any impedance
from 4 to 16 ohms. Should vou wish to drive two
pairs of speaker systems simultaneously by turning
the SPEAKERS switch to the A+B position, each
speaker system should have impedance of 8 to 16
ohms. Using a system to connect two or more
speaker systems to one channel in parallel, their
combined impedance must be more than 4 ohms.
Connecting Record Player
The following procedures are recommended for use
with a player or turntable utilizing a magnetic car.
tridge with an output voltage between 2mWV and
10m.
1, Connect the left channel output of a stereo turn-
table to the LEFT channel (upper) PHONO input
jack on the rear panel of the amplifier.
2. Connect the right channel output of the turn-
table to the RIGHT channel (lower) PHONO input
jack.
3. If a monophonic player or turntable is used, it
may be connected to either RIGHT or LEFT chan-
nel PHONO input jack.
NOTE: Although it is not recommended from a
standpoint of tone quality, if a plaver with a crystal
cartridge must be used, connect the output of the
player to an input jack labeled AUX on the rear of
the amplifier.
To Listen to Records
1, Set the SELECTOR switch to the PHONO paosi-
tion.
2. Set the MODE switch 10 either STEREO or
MONO, depending on the type of record player
used.
3. Switch on the record player and adjust its speed
of rotation (RPM) for the record to be played. (33
14, 45 etc)

4. After placing the needle on the record, adjust
the BALANCE control for equal sound from both
right and left channels.
5. Use other controls and switches according to
vour taste and listening conditions.
NOTE: When playing monophonic records on a
stereo record player, follow the same procedures as
for stereo records for best results. To balance the
sound from both channels, play a monophonic
record the same as a stereo record and adjust the
BALANCE control so that the sound is heard (rom
a point midway between the right and left speakers.

OPERATIONS
——RADIO RECEPTION
The quality of reception that can be expected from
the 1000X is largely dependent on the correct posi-
tioning and use of antennas. The following proce-
dures are recommended for noise-free reception.
FM Antenna
Where FM broadcasting stations are near and FM
signals are strong, satisfactory FM reception can be
obtained by using the feeder wire accompanying
the amplifier, Connect the feeder wire to the an-
tenna terminals marked FM-Al and FM-AZ2 on the
rear panel, then fully extend the wire to a T form
and fix it to a wall or ceiling where it allows the
strongest reception,
If the 1000X is used in à thick-walled building or in
an area remote [rom FM broadcasting stations, the
indoor feeder wire antenna may be inadequate for
strong signal reception. An outdoor antenna de-
signed exclusively for FM reception should then be
installed.
FM antennas for the 300 ohm balanced type and
75 chm unbalanced type can be used with the
1000X. Connect either antenna to the matching
antenna terminals on the rear of the amplifier. The
300 ohm feeder wire should be connected to the
FM antenna terminals Al and AZ. If the 75 ohm
coaxial cable is used, connect the conductor to the
FM antenna terminal A, and the shielding wire to
thé terminal G.
MOTE: FM sensitivity cannot bé raised simply by
lengthening the antenna. Adjust the antenna's
height and direction while actually listening to a
broadcast for the best reception.
Built-in AM Ferrite Bar Antenna
This sensitive antenna, located on the réar panel of
the amplifier, is usually adequate for AM reception.
To use, pull it down and away from the back of
the tuner until it comes to a stop halfway between
the top and the bottom of the amplifier. Then
move it from up to down until best reception is
obtained.
Outdoor AM Antenna
In ferroconcrete buildings or in areas remote from
the broadeasting station, the built-in ferrite bar
antenna may be inadequate for AM reception. An
outdoor antenna then becomes necessary, This can
be accomplished by connecting the PVC wire ac-
companying the amplifier to the antenna terminal
marked AM-A on the back panel. Run this wire
to an antenna that has been installed outdoors and
away from the building. At the same time, the unit
should be grounded. Adjust the outdoor antenna for
maximum signal pick-up, while actually receiving
a broadcast. And, for reasons of safety, bé sure to
attach a lightning arrester to the outdoor antenna,
To Listen to Monophonic
FM Programs
1. Set the SELECTOR switch to the FM AUTO
position.
2. Keep the MODE switch in either MONO or
STEREO position.
3. Turn the TUNING knob to select the desired
station. Once selected, adjust it so that the needle
of the TUNING meter moves as far to the right as
possible,
4, Use all other controls and switches according to
your taste and listening conditions.
To Listen to FM-MPX Stereo
Programs
1. Set the SELECTOR switch to the FM AUTO
position.
2. Set the MODE switch to STEREO,
3. Select the desired FM stereo station with the
TUNING knob and pinpoint the station with the
TUNING meter. If the dial pointer crosses a sta-
tion broadcasting MPX stereo, the FM STEREO
indicator will light up.
4. Adjust the BALANCE control for equal sound
from both right and left channels.
5. Use all other controls and switches according to
your taste and listening conditions.

ELECTRONIC CROSSOVER SYSTEM
Pre- and Main Amplifier Sections
Separately Usable
The 1000X's preamplifier section and the main or
power amplifier section can be used as separate
units by simply removing connectors from the jacks
marked PRE OUT and MAIN IN on the rear
panel. If you want to add another power amplifier
to the 1000X, connect its inputs to the PRE OUT
jacks. For connection of an additional preamplifier,
connect its outputs to the MAIN IN jacks. When
the additional preamplifier is connected, only the
SPEAKERS switch is usable on the front panel of
the 1000X. Thus, tone and volume should be
adjusted by means of corresponding controls on the
additional preamplifier. When the additional power
amplifier is connected, all the controls and switches
on the front panel of the 1000X are usable.
Electronic Crossover System
The independent pre- and power-amplifier sections
make the 1000X more versatile. One of their most
exciting uses is for Electronic Crossover System,
In this stereo system, the frequeney separation is
accomplished electronically between the preampli-
fier and the power amplifiers (in the conventional
system, an LC crossover network is used between
the amplifier and the speakers), and the tweeters,
midranges and woofers are driven independently by
their own power amplifiers. At the present time,
this system is acknowledged as the best system for
true high fidelity sound reproduction.
The features and advantages of the electronic cross-
over system are:
1, Speakers more freely selectable
Since the tweeters, midranges and woofers are
driven by separate power amplifiers, they can be
freely selected on the virture of their tone quality
alone, without regard to their efficiency and imped-
ance characteristics,
2. Better filtering characteristic
Designing a perfect LC crossover network is a
highly complex job, and even the best network may
fail to offer a perfect hltering characteristic. Also,
as the impedance of a speaker varies with frequency,
a network does not always divide the signals at the
predetermined crossover points. In contrast, the
electronic crossover system not only offers a much
better filtering characteristic, but permits changing
over the crossover frequencies and cutoff character.
istics with great ease.
3. Damping factor not impaired
Amplifiers damping factor is not impaired, because
there is no resistance between the amplifier and the
speakers,
4. Power amplifiers used more effectively
Amplifiers best suited for each frequency band can
be used. For example, an amplifier with a fairly
big output is suited for driving the woofers, while
amplifiers with better tone quality characteristics
may be emploved for driving the midranges and
tweeters.

How to Eliminate Radio Noise
AM Reception
AM reception noise can often be eliminated by
changing the position of the antenna. If you are
located far from the broadcasting station, or in the
mountains, a thick-walled building or a block of
such buildings, radio waves will not be well received,
resulting in unstable reception and increased noise.
If reception is poor, connect a vinyl wire (supplied)
to the AM antenna terminal and position it for best
reception. Lf this does not reduce noise or improve
sensitivity, erect an antenna outside the building and
apart from the wall. Some noises are peculiar to a
certain broadcasting frequency or a certain time of
day. These result from the nature of AM signals.
In some cases the noise can be eliminated by ground.
ing the amplifier or reversing the power-cord plug
receptacle connections,
NOTE: If the antenna terminal marked A is touch-
ed with a finger, a hum may be heard. This is a
natural phenomenon: the unit is not at fault,
FM Reception
Noise during FM reception can be generally attrib-
uted to either insufficient antenna input or interfer-
ence [rom other electrical appliances,
Antenna input is insufficient when the antenna is not
installed properly or when the station is far away.
Extend and fix the attached antenna so that noise
is minimized and the antenna input is at maximum.
for better results, install an exclusive FM antenna
in a position to receive signals most effectively.
If you use a T.V. antenna for both T.V. set and
FM unit with a splitter, make sure that the televi-
sion reception is not affected. To prevent noise,
avoid using a long antenna wire,
FM reception is affected considerably by the trans-
mitting conditions of certain stations, usually their
power and antenna efficiency. You may receive one
station quite well and another poorly. To eliminate
interstation tuning noise, use the MUTING switch.
Noise Common to FM and AM
In an area with many ferroconcrete buildings, noise
may occur at a particular time of day. This noise is
easily distinguished from that discribed above. To
eliminate such noise, attach a noise arrester to the
interfering electrical appliances or to the power
source of the 1000X. When you are listening to a
FM-MPX program, you may notice a noise not heard
with monophonic FM broadcasts. The unit is not
at fault, just use the HIGH FILTER switch to elimi-
nate the noise. In some cases, you can also eliminate
the noise by setting the TREBLE control to “flat”
or lower.
Wire Connections
When connecting tape decks, record players or other
components to the 1000X, be sure to use shielded
wire. The use of an ordinary cord or vinyl wire
may cause humming and buzzing. The length of the
shielded wire used should be shorter than 5 feet.
Be sure that all lead wires between the amplifier
and components are properly connected. If the con-
nections are loose or in touch with other parts, the
amplifier will not function properly, may pickup
noise, and even breakdown over a period of time.
Also he sure to read the manufacturer's instructions
for any component before connecting it to the
1000.
The shielded wire is made up for use as illustrated
below:
Connectors between Pre- and
Main Amplifier Sections
Although the 1000X's preamplifier section and
power amplifier section have been connected at the
factory, vou may use each section as a separate unit
for the electronic crossover system, for instance, by
simply removing the connectors from the jacks
marked PRE OUT and MAIN IN on the rear panel.
If you want to connect another preamplifier and/or
power amplifier to the 1000X, refer to the Section
titled under ELECTRONIC CROSSOVER SYS.
TEM. The connectors must be in place unless the
additional component or components will be con-
nected to the 1000X. Warning: Before connecting
or disconnecting, be sure to push the POWER
switch off.
Local-Distant Antenna Switch
This switch adjusts the tuner to the strength of FM
radio waves. It should be set to DIST if the receiver
is located in an area where FM signals are weak,
or to LOC if it is located near broadcasting stations
and there is danger of interstation interference.
Fr" FM |
DIST LOC
MAINTENANCE
Humming and Howling
Care must be taken never to place a record player
on or too near a speaker enclosure. Otherwise the
vibration of the speaker enclosure is transmitted
to the player and causes howling. It is best to keep
these components completely separated, but if this
is impossible, to place a thick cushion between them.
Humming is a phenomenon caused by incomplete
or incorrect player-amplifier connection, If this
occurs, check to make sure that all connections are
complete and that the thickness of the connecting
wire is sufficient. Be sure to connect the grounding
lead (or terminal) of the record player to the GND
terminal of the 1000X, It may suppress the hum
noise which may otherwise occur.
Should the Function Indicator Fail
to Light...
If one or more function indicators fail to light in
the dial window when the SELECTOR switch is
turned to the appropriate position, it is most likely
one or more indicator lamps behind the window
have burnt out. To replace, remove the bonnet
from the amplifier (see Service Manual).
Quick-Acting Fuses
These fuses for right and left channels are also de.
signed to protect the transistors by blowing instantly
if shorting occurs between connections at a speaker
system terminal. If, after the POWER switch is
turned on and the function indicator or dial scales
lights up, neither channel operates or only one
operates normally, is either because one or both
Quick-Acting fuses have blown. In this case, re-
move the 1000X's power supply cord from its outlet,
screw out the fuse holders on the rear panel, and
check to see if the fuses are blown. Replace them
with identical 2.5A fuses after finding and eliminat-
ing the source of trouble that caused them to blow.

DIN Socket
If your tape deck has a DIN socket, it may be
connected to the 1000X simply by the use of a cable
with a 5-pin DIN connector on each end. Insert
each connector to the DIN socket on the receiver's
rear panel and into the one on the tape deck. The
DIN connection system, designed to simplify inter-
connections between the tape deck and amplifier, is
based on the German DIN Standards.

Grounding
Connect one end of vinyl or enameled wire to the
terminal screw marked GND at the rear of the am.
plifier, attach a copper plate to the other end, and
bury it underground. Whenever an outdoor AM
antenna is used, grounding becomes necessary. In
all cases, grounding is desireable since it allows a
better SN ratio to be obtained. To ground an en-
tire audio system, connect the grounding wire of
each component used to GND terminal.
AC Outlet
The 1000X is provided with AC outlet on the bock
panel. It is controlled by the POWER switch on
the front pañel.
CAUTION: 1. The maximum capacity of this
outlet is 50VA. Never use it beyond its rated ca-
pacity.
2. The voltage supplied by the AC outlet is the
same as the power supply voltage used.
Power Fuse
Should the amplifier fail to operate and the function
indicator fail to light up when the POWER switch
is truned on, the probable cause is either a power
stoppage or a blown fuse. To check, remove the
1000X's power supply cord from its outlet, turn the
{use holder on the rear panel counterclockwise, and
remove the fuse. If it is blown, replace it witha
new glass-tubed fuse of the same capacity (100~
127V—3A, 220~-250V—2A) after determining and
eliminating the trouble source that caused the fuse
to blow, Using wire or a fuse of a different capacity
as a stop-gap measure is dangerous and should be
avoided.

Voltage Adjustment
To reach the Voltage Selector, remove the two
screws from the nameplate on the rear panel and
then remove the nameplate. The Voltage Selector
makes it possible to operate the 1000X at the correct
voltage in any area.
The voltage has been pre-adjusted at the factory,
but can be easily readjusted as follows:
STEP I Set arrow of main Voltage Selector plug
to required voltage: 100, 110, 117, 127, 220, 230,
240 or 250 volts.
STEP II If numerals of voltage are printed in red,
set arrow of adjacent sub V.5. plug to position
marked red. If they are printed in white, set arrow
to position marked white,
STEP III The power fuse should also be changed
whenever the AC line voltage is changed. For 100~
127 volt operation a 3 ampere fuse is required. For
220—250 volt operation the fuse should be changed
to a 2 ampere unit.
NOTE: The Voltage Selector can be used to elimi-
nate the trouble caused by the considerable voltage
fluctuation. In this case, it should be set to the peak
voltage.
