A special circuitry has been incorporated in this unit so that
more than one set of speakers (in different rooms, for instance)
can be hooked up.
4, 8, or 16 ohm speakers are suitable. In connecting only one
set of speakers, connect the right speaker to right speaker terminals
and left speaker to left speaker terminals of “A” terminals. Should
plus or minus of either right or left channel be reversely connected,
sounds from the center section will be affected by a lack of separa-
tion. To connect a second set of speakers, connect right speaker to
right speaker terminals and left speaker to left speaker terminals
of “B” terminals.
@ “A e B SPEAKERS” position of the OUTPUT selector switch
will not work unless both A speakers system and B speakers system
are connected.
@® See Figure 1 for making proper connections from the B
SPEAKER OUTPUT when it is desired to use three sets of speaker
systems.
@ Proper phasing of the two speakers is important for deriving the
best performance. This is to assure that low frequency or bass tones
are not eliminated by speakers that are working in opposition to each
other.
@ After your speakers are connected, listen to the intensity of the
bass tone. Then reverse the lead connections of the speakers and
listen to the sound again. The position of the lead connections where
the bass intensity was the greatest is the proper one and the speakers
will then be permanently in phase.
SIT ERE {
Enjoy the wonderful sounds of stereo without disturbing others
or monitor the playback of tapes as you record them with your
stereo headset. Plug the headset into the STEREO PHONES JACK
and turn the OUTPUT selector switch to PHONES position.
You may tape FM MONAURAL, FM STEREO, AM and RE-
CORDS by connecting the output jack of TAPE REC to the input
jack of the tape recorder. Play back your recordings by simply
connecting the line output of your tape recorder to the TAPE PLAY
jack of your KR-100 (Diagram, page 3.)
Note: KR-100 has a DUBBING TAPE REC Jack in its front panel
as well as on the rear panel so that the connection can be made
easily between a Tape Recorder and KR-100. (See page 10)
How to wire the connection plug is as shown in Figure 2.
Fig 2 Connection of Tape Recording Plug
The two lines of shielded cord from your stereo record player
should be terminated with RCA type phono plugs. Cords should
not exceed ten feet in length. (An excess will create a loss in
high frequency range).
Two pairs of stereo phono inputs have been incorporated in
this unit so that two sets of stereo record players can be hooked up.
When operating MAG 1 (or MAG 2), switch the output selector
switch to Phono 1 (or Phono 2).
Auxiliary inputs can be used for a second tuner, tape recopying,
“etc. (See Figure 8, page 9).

Stereo pre-amplifier outputs and stereo main amplifier inputs
are incorporated in this unit. When using this amplifier as a pre-
amplifier or a main amplifier only, remove the attached jumper con-
nector and connect another main or pre-amplifier. When making
a multi-channel system with this amplifier, remove the attached
jumper connectors and insert a dividing filter between main ampli-
fier inputs and pre-amplifier outputs. The input impedance of main
amplifier is 50 K ohms and its input sensitivity is 100 mV. (FIG. 3.)
When using this KR-100 as a pre-main amplifier, do not remove
the jumper connector from the unit.
The output voltage of this jack is about 1 V (at 1 K ohms output
impedance), which is the mixed monaural signal of left and right
channels. Connect this to the AUX input jack of the monaural
amplifier to drive the extra speaker.

POWER
Plug the AC line cord into an outlet furnishing 110 to 120 volts
or 220 to 240 volts AC, 50 — 60 Hz.
The AC outlets on the back of the amplifier may be used to
supply power to other components, such as a record player, tape
recorder, etc.
1. Switch outlet (60 watts)
This is switched with the power switch on the amplifier.
IMPORTANT! Do not connect any electrical equipment with a
power consumption of more than 60 watts.
2. Unswitched outlet (300 watts)
This is not connected to the power switch on the amplifier.
IMPORTANT! Do not connect any electrical equipment with
a power consumption of more than 300 watts.
NOTE: AC VOLTAGE SELECTION
This unit is pre-set to be used at 220 — 240 volts AC. In countries
with 110 — 120 volts AC, set the AC switch from 220 — 240 volts to
110 — 120 volts as follows:
1. Turn the power switch to “OFF”.
2. Remove the black plate which is affixed to the AC switch on
the rear panel.
3. Set the slide switch to the left.
4. The black plate has 220 — 240 V stamped on one side and
110 — 120 V stamped on the other side. Affix this black plate
so that the 110 — 120 V mark is visible.
Figure 5 illustrates the AC switch set for 110/120 volts AC.

The ferrite stick built into the Model KR-100 assures adequate
reception of all local AM stations. However, in fringe areas, high
noise areas, or where surrounding metal objects interfere with normal
reception, a regular antenna lead should be connected to the terminal
designated AM.
NOTE: The ferrite stick is mounted on a swivel bracket. For
maximum pickup, the stick should be swung away from the
chassis.

Three terminals are provided for connection to a 300 ohms and
_75 ohms FM antenna as shown in Figure 6.
For good FM stereo reception, always use the best antenna
possible. In areas close to the transmitter, a simple indoor dipole
antenna may suffice. (It should be remembered, however, that the
pickup of reflections (similar to “ghosts” on TV) will result in
poor stereo reception. These reflections must therefore be reduced
to a minimum, either by careful orientation of the indoor antenna
or, if this will not eliminate them, by using a more directional
outdoor type antenna.
In areas a greater distance from the transmitter, the use of
an outdoor antenna is highly recommended. These are available in
various types. For reception of stations scattered in many direc-
tions, a non-directional type may be required. If the desired stations
lie mostly in one direction, a high-directional type of antenna will
offer better results. When using a directional antenna, always
orient it for the best reception of the desired station. The correct
position will be indicated by maximum deflection of the tuning
meter on your receiver.

Normally for most recording and playback, separate cables must
be connected to their respective input jacks on the amplifier; how-
ever, if your tape recorder is equipped with R & P (Record and
Playback) 5-Pins connector type patch cord, a special jack (connector)
is provided on the KR-100 enabling both recording and playback
with this single cable.
é
Tape recorder with direct tape head output should be connected
to the TAPE HD inputs. As the output voltage of a tape head
is very low the cable may pick up hum; therefore the cable should
be carefully positioned to eliminate any hum.

The KR-100 incorporates a Tape Monitoring circuitry enabling
you to monitor while you record. Connections to the tape recorder
are made as explained in the section dealing with “Interconnecting
Diagram”.
For Two-head Tape Recorders
Ordinary two-head type tape recorders are not equipped with a
separate playback monitor amplifier to enable tape recording and
simultaneous monitoring. Therefore, when recording, set the Tape
Monitor Switch to OFF position, and feed the signal to be re-
corded through the KR-100. And, for playback of the recorded
tape through the KR-100 speaker system, set to ON position.
For Three-head Tape Recorders
Three-head type tape recorders have separate recording and
playback heads, and their respective separate amplifiers.
enables simultaneous playback monitoring of the recording.
This
For
operating the KR-100 in conjunction with three-head type recorders,
set the TAPE MONITOR switch to ON position.
This enables
monitoring the recording and fully controlling level, acoustic balance,
microphone position, etc. :
For playback of the recorded tape, set to OFF position.

WARNING
The newly developed protection circuit is completely effective
and prevents damage which may be caused by short circuits at the
speaker outputs or the electrical overloading point. When a short
circuit occurs this protection circuit will function automatically to
protect the transistors. The program sound will be heard off and
on intermittently about every one second. In this case, there is
no fear of damaging the transistors. Just switch off the supply
line and check the connections.
Shield 2A fuses are used; Rotate the fuse holder counter-
clockwise for replacing. If a fuse fails, check carefully the reason
for the blow-out and then replace the fuse. When something is
wrong with the supply circuit, the fuse will blow again. Do not,
in any case, use copper wire in place of the specified shield fuse.

DIRECTIONS FOR PANEL MOUNTING FOR KR-100
. Locate the supporting shelf at the height you wish the receiver positioned.
Using the full scale “Cutout Template” make a 4-7/16”15-7/16" cutout in the
cabinet panel. The bottom of the cutout should be flush with the bottom plate of
the receiver as shown in the side view. The distance between the bottom of the
cutout and the top of the supporting shelf is 9/16.
The receiver is held in place by two bolts. The holes must be made in the shelf
to correspond with the holes in the receiver. Use the “Top view” template to loca-
te these holes on the supporting shelf. The holes should be made 1/4” in diameter
or somewhat larger.
Remove the four bottom legs.
5. An air space must be made between the bottom of the set and the supporting shelf
to assure good ventilatidn and cool operations. This spaces can be made by placing
two boards which measure 9/16” thick by 1” width between chassis and the supp-
orting shelf.
