HIGH SELECTIVITY IF STAGES
Excellent capture ratio, stable operation and sharp selec-
tivity are assured by three ceramic filters in the IF stages
and IC fimiters. The filters never need realignment and
contribute to high reliability against aging and ambient.
temperature variations.
QUADRATURE DETECTOR AND PLL
MPX DEMODULATOR
A balanced bridge differential amplifier performs quad-
rature detection of the FM signal. Linearity is assured
throughout the frequency band, while distortion becomes
minimized. Clear and stable separation is provided by the

circuit
design.
REDUCED DISTORTION AM CIRCUIT
Careful engineering is also evident in the AM tuner circuit.
Automatic gain control in the RF and IF stages, together
with a 3-gang variable capacitor and IC circuitry deliver
improved image ratio, selectivity and frequency response,
plus reduced distortion.
HEAVY DUTY SPLIT POWER SUPPLY
The dual positive and negative power supply incorporates
extra large 22,000 uF electrolytic capacitors and possesses
plenty of reserve power. Protection and muting functions
are included to both safeguard equipment and eliminate
power on-off noise.
PRECISION RIAA PHONO EQUALIZER
Deviation from the RIAA standard is performed within
+£0.3dB, while the ability of the phono inputs to accept
relatively strong signal fevels without distortion (200
mV rms) results in a wide dynamic range.
HIGH RELIABILITY PROTECTION CIRCUIT
In the event of malfunction, valuable semiconductors and
speakers
are
protected
by
a

PHONO 1 and PHONO 2, enabling two turntables
fitted with magnetic phono cartridges to be con-
nected.
® Connections between the turntable OUTPUT
terminals and the receiver PHONO input jacks
should be made as shown in Fig. 3, taking care
not to confuse L & R channels. If, as in Fig. 3,
the turntable is fitted with a ground lead or plug,
this should be connected to the receiver GND

3. Adjust the sound level by turning the VOLUME
control gradually to the right. The midway set-
ting of the BASS and TREBLE controls will
usually give best results.
PROTECTION CIRCUIT
For some 3 to 6 seconds after the receiver is
iswitched ON, no sound will be heard. This is due
‘to the operation of protection circuits which are!
[designed to safeguard transistors and speakers
from possible damage, due chiefly to switching
transients, etc. Should the receiver remain silent
for considerably longer than this, switch off and
check the speaker system connections. Should the
receiver suddenly go silent while you are listening
to it, and a continuous series of “clicks” can be
heard due to relay contacts opening and closing
within the receiver, this can be an indication of a
short circuit in the speaker system connections.
Switch off, and re-check the speaker system imped-
ances, etc.
The protection circuit re-sets itself automatically,
so that normal operation is resumed as soon as the
[fault is cured.
NOTE:
Under certain conditions the microphone is liable to give
rise to “howling” or feedback noise. Be careful not to
raise the volume too high when the microphone is close
to the speaker systems or in a room with a great deal of
resonance. This tendency can be reduced by setting the
TREBLE and BASS controls to their “0” positions, or by
switching the TONE switch OFF (up)
TURNOVER SWITCHES
The SX-950 provides two special bass and treble
turnover frequency selector switches. Each switch
and two numbers, the BASS 400 and 200Hz, the
TREBLE 2.5k and 5k, which show the frequencies
at which the BASS and TREBLE controls begin
to act.
Fig. 10 shows the response curves indicating the
relation between the TURNOVER switches and the
TREBLE controls.
These are a very convenient way of adjusting the
tone quality to suit the characteristics of the room,
the program source, the cartridge characteristics
or your personal taste, etc.

TAPE DECK OPERATION
TAPE DECK CONNECTIONS
Two sets of recordmg output jacks (TAPE 1, 2
REC) and two sets of playback input jacks (TAPE
1, 2 PLAY) are provided, plus a DIN-type
recording/playback connector (TAPE 2 REC/
PLAY).
This
means
that
in
addition
to
normal
recording
and
playback,
two
decks
can
be
used
to
record
at
the
same
time,
or
to
“dub”
or
duplicate
recordings
from
one
tape
deck
to
the
other.
Use
the
connecting
cord(s)
provided
with
the
tape
deck(s)
to
make
the
connections
(see
Fig.
11).
A
tape

can
also
be
connected
to
the

use
an
optional

NOTE:
As the recording/playback cord connects both recording
and playback functions at the same time, there is no need
to make separate connections to either TAPE 2 REC out-

CONNECTIONS FOR SETTING UP A MULTI-
AMPLIFIER SYSTEM
By purchasing an electronic crossover network and
one or two additional power amplifiers, a two- or
three-way multi-amplifier system can be con-
structed. This splits up the audible frequency range
into different frequency bands, to operate ampli-
fiers and speakers ideally suited to each band.
The results are reduced intermodulation distortion
and improved damping and crossover charac-
teristics. Use of the multi-amplifier system is as
follows:
1. Remove both of the plugs bridging the PRE
OUT and POWER IN jacks.
2. Connect the PRE OUT jacks to the input jacks
of the crossover network.
Power Amplifier
Left Channel Speaker
Right Channel Speaker
Fig. 24
3. Connect the POWER IN jacks to the LOW range
jacks of the crossover network.
4. Connect the HIGH range output jacks of the
crossover network to the input jacks of a
separate power amplifier for the high frequency
range.
. Connect the speakers for the lower frequencies
to the receiver, and those for the higher fre-
quencies to the separate amplifier.
The levels of the different frequency ranges are
adjustable by the crossover network. For detailed
instructions on the use of the crossover network,
please refer to the instruction manual provided
with it.
