INSTALLATION PROCEDURE
VENTILATION
Although your new Nocturne Receiver rarely develops high heat, it
is still
recommended that you leave the back of the cabinet open. If this
is not possible,
provide several large holes or slots as low down and as high up in the cabinet
back as possible. As an alternate, holes may be provided in the sides, bottom
or top of the cabinet. Remember that really effective ventilation requires pro-
vision for cool air to enter at the bottom and hot air to leave at the top. A
minimum clearance of two (2) inches should be allowed on each side and in the
rear, between the chassis and the cabinet, and three
(3) inches are required
above it.
Isolate any accessories which might interfere with ventilation. For example,
do not drape plastic or rubber covered interconnecting cable over the equipment.
The rear panel surface of your receiver has been designed as a heat dissi-
pating device for the output transistors. This area will become warm under normal
use and should not be cause for concern.
POWER REQUIREMENTS
Connect the AC line cord into any outlet furnishing 11
7 volts, 50 or 60 cycle
AC current. The voltage may vary between 105 and 125 volts. An auxiliary AC
power outlet
is provided on the rear panel of your receiver. Any accessory equip-
ment (tape recorder, phonograph record player, etc.) may be connected to this
receptacle and will be controlled by the ONOFF switch on the front panel of your
receiver.

CONNECTING THE SPEAKERS FOR STEREO OPERATION (1 SYSTEM) SPEAKER PHASING
Your two speakers should be identical,
if possible, to obtain optimum results.
Experts agree that a perfectly matched system offers the best stereophonic repro-
duction. The speakers should be placed along the same wall approximately
8 to
10 feet apart depending upon room size and furniture placement. It may be
necessary to experiment with speaker placement until best results are obtained.
Use any type of wire to connect your speakers to your receiver. Lamp cord
"zip cord"
is excellent and may be easily dressed around the molding for an
inconspicuous and neat installation. Do not drive the staples or tacks through the
center of the wire for this may short out the two sections and will decrease the
overall volume or short out the speakers entirely. It
is permissible to use approxi-
mately
50 feet of speaker connecting wire for each speaker without loss of
volume. CONNECT SPEAKERS WlTH CARE. AVOID SHORTS-RECEIVER HAS BEEN
DESIGNED TO PREVENT DAMAGE FROM ACCIDENTAL SHORTING; HOWEVER,
REPETATIVE SHORTING CAN DAMAGE TRANSISTORS.
1. Connect one length of lamp cord to the left speaker. (This is the speaker
on your left as you face the speakers. This speaker will now be referred to as
Channel A.)
2. Attach the other end of the lamp cord to the terminals marked SYSTEM
1 CHAN A located on the rear of the receiver.
3. Similarly connect another length of lamp cord to your right speaker. (This
speaker will now be referred to as Channel B.)
4. Attach the other end of the lamp cord to the terminals marked SYSTEM
1 CHAN B.
5. Your receiver is now connected for 1 system stereo operation and is
operative when the speaker switch on the front panel is in the System 1 on
position selector.

When more than one speaker is used in any music reproducing system the
speakers must be connected in a manner to work together rather than work out of
phase. If one speaker
is pushing air out while the other is moving in the opposite
direction this will result in diminishing bass-response. Checking for proper phase
and correcting
if necessary is quite simple.
1. Place
a stereophonic recording on your record player
2. Place the Function switch in the Phono Mono position for monophonic
playback.
3. Play the record. The sound should emerge from approximately the center
area between the two speakers.
4. While the record is playing place the Function switch in the Phono Stereo
position.
5. The sound should now move across the wall of the room and should
appear to come from both speakers as well as the center.
6. If your speakers are out of phase, the sound source will not pinpoint
itself between the two speakers when the Function switch
is in the Phono Mono
position. Instead it will appear to come from both sides.
If the speakers are out of phase, turn off the receiver and disconnect both
leads from either the left or right speaker and reverse them. Your system will now
be in phase.
This completes your speaker connections. Your receiver
is a solid state
device which does not contain audio output transformers. It
is therefore not neces-
sary to match the impedance of your speakers to the receiver. Your unit will per-
form perfectly with any speaker which has an impedance of
4, 8 or 16 ohms.
SPEAKER SYSTEM SELECTOR SWITCHES
Your receiver has been provided with
2 independent speaker selector
switches.
If your receiver
is connected with 1 set of speakers (1 system) as described
in previous paragraph on speaker connectors, the system
1 speaker selector switch
must be in the "on" position.
If you have 2 sets of speakers (2 systems) the
system 1 and system
2 speaker selector switches must both bein the "on" position
for both systems to operate.
Should you desire to listen to stereo-headphone alone, the speakers (either
one or both systems can be turned off at your discretion.)
STEREO HEADPHONE RECEPTACLE
The stereo headphone receptacle located on the front panel will accept
any headphone with any impedance rating. The headphone receptacle
is "on"
at all times. If you wish to listen to the headphones alone, see the paragraph
"Speaker Selector Switches".

CONNECTING THE SPEAKERS FOR STEREO OPERATION (2 SYSTEMS)
1. Connect all 4 speakers for your two system operation as shown in
Diagram
B.
2. You may now select either system 1, system 1 and 2 or system 2 by the
use of the speaker selector switches located on the left side of the front panel
of your Nocturne receiver.
NOTE: WHEN ALL THE SPEAKERS USED IN YOUR
2 SYSTEM CONNECTION ARE
4 OHMS, CONNECT A 2 OHM, 10 WATT RESISTOR IN SERIES WlTH THE
HOT SIDE OF EACH OF THESE SPEAKERS. (IF TWO OF THE SPEAKERS ARE

CONNECTING THE FM ANTENNA
Due to the exceptionally high sensitivity of your receiver, the
48" wire
supplied
is sufficient for all but the most difficult locations. The balanced antenna
input
is designed to accept a 300 R antenna, indoor or outdoor type. When
using the antenna supplied connect one end of the
48" wire to either of the FM
antenna terminals. Horizontal placement of the antenna will yield optimum recep-
tion. The antenna may be tacked to the back of the molding behind the equip-
ment or to the shelf you use.
As FM signals are in the same broadcast frequency range as
N signals,
they are affected by the same external conditions. Just as
TV reception is im-
proved, you can improve your FM reception with an external antenna. When
using an external antenna connect both leads of the antenna wire to the two FM
antenna terminal posts on the rear of your receiver.
CONNECTING THE AM ANTENNA
The AM loopstick fastened on the rear of your receiver comprises all the
antenna usually required for normal signal areas. In more remote locations an
additional outdoor antenna may be required. This should consist of a single wire,
as long as
is reasonably practical. It must be kept away from large metal objects,
power lines or electrical machinery to insure reception without extraneous noise.
Attach this length of wire to the AM terminal of the ANTENNA TERMINAL
STRIP.
CONNECTING A STEREO RECORD PLAYER - (MAGNETIC PICKUP)
Connect both leads from your record player to the CHAN A and CHAN
B
PHONO MAG input receptacles on the rear of the receiver chassis. If your record
player has a special ground wire emerging with the two input leads, connect this
ground wire to the ground terminal on the rear of the receiver.
CONNECTING A MONOPHONIC RECORDPLAYER
- (MAGNETICPICKUP)
Connect the single lead from your monophonic record player to either the A
or B PHONO MAG input receptacles on the rear of the receiver chassis.
CONNECTING A STEREO TAPE RECORDER
Connect the two tape recorder output cables to the LEFT and RIGHT TAPE
AMPIAUX input receptacles on the rear of your receiver. With the Function Switch
in the TAPE AMPIAUX position you will now be able to play your stereo tapes.
In order to make a recording, connect the inputs of your tape recorder to
the TAPE OUT receptacleson the rear of the receiver. This will allow you to make
a stereophonic recording while simultaneously listening to the program material
through your spe'aker system.
CONNECTING A MONOPHONIC TAPE RECORDER
If a monophonic tape recorder
is to be used with your receiver connect the
recorder output to either the CHAN A or CHAN B AUX input receptacle located
on Ihe rear panel. This will enable you to play back your monophonic tapes.
If your recorder
is stereo playback but records monophonically, connect the
output as described in the previous section on connecting a stereo tape recorder.
Connect the input for recording monophonically as described below.
Connect the input of your recorder to either the CHAN A or CHAN B TAPE
OUT receptacle. This will enable you to record monophonically while simul-
taneously listening to the program through the receiver and speakers.
OPERATION PROCEDURE
Every control on this receiver serves a specific useful function and
is im-
portant for the proper operation of your stereo system.
We recommend that you read the following section carefully so you may
take full advantage of the performance capabilities of your receiver.
BALANCE CONTROL
The balance control
is used to adjust the sound level of each channel with
relation to each other.
The nature of stereophonic reproduction
is such that it requires two identical
channels to obtain the optimum stereo effect. As there may be slight differences
between the location of the two speakers, tape heads, cartridges, etc., the
balance control
is provided to permit re-balancing of the overall system even in
extreme cases where unbalance exists.
It should be noted that the Balance Control may be set anywhere within its
range of adjustment to attain system balance.
VOLUME CONTROL AND POWER SWITCH
The Volume Control
is used to adjust the volume level of any program
material fed into the stereo system. The control varies both channels simultane-
ously therefore eliminating the necessity of balancing your system each time you
change the volume level.
In the full counter-clockwise position your receiver is OFF. In order to turn
your receiver ON, turn the control clockwise until a click
is heard and then adjust
the volume level of the program you wish to hear.
BASS AND TREBLE CONTROLS
The BASS and TREBLE tone controls on your receiver provide the full range
of tonal adiustment necessary for stereo high fidelity listening. The tone control
range
is considerable and can adequately adjust the low and high frequencies
in accordance with your listening preference, speaker characteristics and room
acoustics.
For your convenience the "Contour Defeat Switch"
is now an integral part
of the "Bass Tone Control." For warm full bodied reproduction at low listening
levels leave the switch in the normal (in) position. To defeat the contour pull the
bass control out. At high levels the contour/defeat switch has no effect.
CONTOUR DEFEAT SWITCH
One of the limitations of human hearing
is its tendency to lose sensitivity to
the very low pitched sounds as the program sound level
is reduced. It is this
characteristic (known as the Fletcher-Munson effect) which causes one to play
music programs at high listening levels in order to experience the full rich tone
available from fine modern recordings.
The Contour/Defeat switch compensates for this effect; thereby eliminating
high listening levels as a requisite for full enjoyment of reproduced music.

FUNCTION SELECTOR SWITCH
The Function Selector Switch selects the desired type of program source to
be heard thru your system.
1. PHONO MONO: Selects your record player for monophonic operation.
2. PHONO STEREO: Selects your record player for stereophonic operation.
3. TAPE AMPIAUX: Selects any program source such as tape recorder,'
the output of your television set, or any other high level equipment con-
nected to the tape amp/aux receptacles on the rear of your receiver.
4. FM MONO: Selects the FM section of your receiver. In this position you
can listen to stereophonic broadcasts monophonically while monophonic
broadcasts will appear unchanged.
5. FM STEREO: This is the normal listening position for all monophonic
or stereophonic FM broadcasts. In this position the stereo indicator light
and automatic switching circuit built into your receiver are operative. For
further details see the paragraphs on "Stereo Indicator Light" and
"Selecting Monophonic or Stereo FM Broadcasts".
6. AM: This position selects the AM section of your receiver for AM recep-
tion. (Two Ten only)
TAPE MONITOR SWITCH
If your tape recorder has a special monitoring feature throwing the tape
monitor switch to the "in" position will enable you to listen to your tapes a
second after they are recorded. When not in use, this switch must be in the "out"
position. If your tape recorder does not have any monitoring feature, throwing
this switch will result in zero output from your speaker system.
SPEAKER SELECTOR SWITCHES
Refer to paragraph on speaker connections
TUNING METER
Your receiver incorporates a D'arsonval movement tuning meter for precise
tuning of your receiver.
Proper tuning
is indicated by maximum deflection (higher number) of the
needle. Stronger stations show greater needle movement.
TUNING
The tuning knob, located directly to the right of the dial glass is used to
select the desired FM station when your selector switch is in the FM mono or
FM stereo position.
SELECTING MONOPHONIC OR FM STEREO BROADCASTS
Under normal use for all FM broadcasts the function Selector Switch should
be placed in the FM STEREO position.
Your receiver
is equipped with a stereo sensing circuit which can auto-
matisally determine
if your unit is receiving monophonic or stereophonic broad-
casts, and then automatically adiust the mode of operation.
If the station
is transmitting stereo, your receiver will automatically switch
in the multiplex section and you will hear the broadcast in full stereo. S-houldthe
station conclude broadcasting in stereo, your receiver will automatically switch
back to monophonic reception.
Should you receive a weak stereo signal whose quality has been degraded
by noise or poor signal conditions, and you wish to listen to this stereo broadcast,
monophonically, place the function selector switch in the FM MONO position.
STEREO INDlCATOR
A stereo indicator is located directly behind the FM dial glass and operates
in conjunction with the FM Stereo position of the Function switch. The indicator
visually indicates the reproduction of FM stereo through your receiver.
To tune for FM stereo proceed as follows:
1. Place the function selector switch in the FM Stereo position.
2. Tune carefully to the desired station, using your tuning meter for maxi-
mum deflection. Your stereo indicator will now show
if you are tuned to
a stereo program. If the indicator is OFF, the program you are listening
to
is being broadcast monophonically.
DIAL SCALE
The Dial Scale on your Two Hundred receiver is marked with two (2)
scales, an FMfrequency scale (88-108 mc) and a logging scale (0-100). The Two
Ten receiver however is marked with three
(3) scales, an AM frequency scale,
FMfrequency scale, and an
FM logging scale.
Since most
FM stations operate on frequencies which are not whole numbers
(such as 96MC as compared to 96.3) ideally each megacycle division on the
frequency scale should be divided into 10 parts to enable the user to pinpoint
the location of the station. This would require a dial scale which would be longer
than the front panel.
The logging scale which
is divided into 100 equal parts provides a means
of finding your favorite station, once you have noted its position on the logging
scale. For example, in New York City, WQXR operates on 96.3 MC. After locating
this station through the use of the frequency scale (between
96 and 98 MC), you
find that the pointer may fall on 46 on the logging scale. Make a note of this
setting and when you next want to tune taWQXR, all that
is necessary is to set
the pointer to 46 on the logging scale.
EQUALIZATION
In order to achieve good reproduction of the wide range of frequencies in
music and to make necessary adjustments for the limitations of the recording
technique, record manufacturers have found it necessary to modifi the actual
frequency response of the music.while it
is being recorded. Thus, to avoid over-
cutting and consequent distortion, a measured and deliberate reduction
is
effected in low frequency response by selecting a "turnover frequency" and by
recording attenuated response below that point. To assure optimum signal to
noise at the high frequency end when the record
is played at home, the highs are
deliberately exaggerated during the recording process. A measured and deliber-
ate boost
is effected above a certain frequency. This combination of deliberate
exaggeration at the low and high ends of the frequency response can be
expressed in a recording curve. When the record is played a mirror image of that
curve should be available so that the ideal "flat" response may be achieved.
The PHONO positions of the Function Selector automatically select the
proper equalization that is required.

Your receiver is protected by a 2% amp-3AG fuse. In the event of fuse
failure replace ONLY with the same type used. Replacing with a fuse of a higher
rating will not protect the instrument and may result in severe damage.
HUM AND NOISE
12
MIN
In any high fidelity installation, hum may be caused by the interconnection
of a record player, tuner and amplifier, as a result of the cables and different
grounds. If hum
is experienced with your receiver, disconnect everything but the
speakers from the receiver. If hum persists, reverse the AC line cord. Plug in the
record player and if hum appears, reverse the record player power plug and
connect a single lead from the record player chassis to the ground post on the
rear of the receiver chassis. Connect your other devices in this manner. CAUTION:
Hum may be also induced by defective connecting cables or by running these
cables too close to a strong AC field.
