AM/FM STEREO RECEIVER model R1500 OPERATION MANUAL

You are about to begin a new high f idelity experience. The

LUXMAN R-1500 Receiver is unique in the annals of high

fidelity equipment. Though built with extremely sophisti-

cated engineering, its concept is quite simple: to produce a

receiver with performance comparable to that available in

the f inest separate tuners, preamplif iers and amplif iers.

After extensive research,the R-1500 was designed without

compromise to provide high output. low distortion and an

exceptionally wide range of available power. ln addition,

this unit reflects great attention to control flexibility and

human engineering.

The R-1500 represents the finest standards of design and

craftsmanship, but the proof is in the handling... and in

the hearing. As you proceed to connect the receiver. may

we suggest you read all the ¡nstruct¡ons carefully before

turning the unit on? A few moments invested now can

eliminate doubts or delays later.

lf you have any questions, please do not hesitate to consult

your dealer, or distributor in your territory.

Pleasurable listening!

NAMË AND USAGE OF EACH CONTROL

1. INPUT SELECTOR SWITCH

This switch permits proper selectìon of desired progranìme

sources. You may set either of the positions (Aux-1 , Aux-2,

Phono-.1 , Phono-2, FN/, AN/l)

2. AM/FM DÍAL

Turn tìre tuning knob according to the f requencies marked

on this dial and the desired signal can be received. Receiva-

ble frequency range for FIV js from SBMHz to 108MHz,

while for AfV from 525Kl¿ to 1605KH2. When a stereo

FIV is being received the "stereo" beacon is illuminated

3. SIGNAL STRENGTH METER

The accurate tuning point can be obtained when the

needle of this meter shows its maximurn swing The move-

ment of the needle depends on the strength of the receiving

signal Even if the needle swings to the extreme right it

does not irnpair the meter. But for perfect reproduction of

stereo FlVl, it is recommended to have the needle's swing

exceeding "4" on this meter.

ln case of FI\4 reception such signals as cannot be cut off

when the muting switch(14) is at the "on" position are

used as stereo reception.

MICROPHONË LEVEL CONIROL

(PULL ON MIC IEVËL)

4. FM FINE TUNING METER

When no FM signal is received this pointer rests in the

vicinity of the centre position. When the tuning knob( 5 )

ìs turned and the needle of fine tuning meter(4) begins

to swing, the needle of this meter comes out of the centre,

and as the accurate tuning point is getting very near the

needle cornes back again closer to the centre. Thus the

accurate tuning point can be obtained with the needle at

lhe dead centre position This meter is exclusively effective

on FN/1, and in case of AM reception the needle does not

move from iLs cenLre poinL.

5. TUNING KNOB (TUNING}

Use this knob for tuning on station. When any desired

signal is received make accurate tuning slowly so that the

pointer of signal strength meter( 3 ) shows its maxirnum

swing and that for f ine tuning meter( 4 ) comes to íts

centre position. For AM reception this centre tun¡ng meter

does not operate.

6. STEREO BEACON

When selector switch(1 ) is set to "FM" position this

stereo beacon lights up in case the FN/ stereo signal is

receiving, while it does not light up for the mono signal.

Further when monaural FM on reception changes into

stereo this beacon lights up automatically to indicate

stereo recept¡on. On the contrally if reception changes

from stereo to mono, the beacon does not light. In

case rnono reproducÌion of stereo signal is desired, set

the mode selector switch (9) to mono position.

MICROPHONE LEVEL CONTROL (PULL ON MIC.

LEVEL}

The input level of the microphone jack(8 ) is controlled by

this knob Normally this switch should be left pressed in.

Pull the knob outwards and the crrcuit is put into opera-

tion. Then turn it clockwise so that an appropriate level

can be obtained A word of warning: do not turn the main

amplifier volume up too loud as annoying feedback "howl"

might take place between your speakers and microphone.

Experimenting will help you find the best levels for each of

these controls.

8. MICROPHONE JACK (MIC. R. L. CHANNEL)

lnput sensitiv¡ty 2mV; input lmpedance 50 Kohms.

Both L-channel and R-channel have ìts own standardized

jacks, and STEREO SOUND N4 lXlNG of mic input with

other programme sources is possible when two rnicrophones

(stereo) are plugged in These jacks accept the microphone

of 600 ohms (low impedance) or 50 Kohms (high im-

pedance) type and the rnput is amplif ied and controlled by

the |evel control volume( 7 ) so that it can be mixed to

both channels respectivelY

9. MODE SELECTOR SWITCH

This switch allows seleclion of sound reproduction modes

such as Stereophonic, Monaural and Stereo-reverse For

f rrrther details refer to the "Mode Selection"

10. TAPE DUBBING SWITCH

The dubbing lever switch has three positions: in the centre

position "source", which is the programme source as

selected by the f unction selector. When moved to the "up"

position(1 to 2) it will allow the output of tape recorder

"1" to go to the input of tape recorder "2" for dubbing

(reprint). Beprint from tape recorder "2" Iorape recorder

"1" is allor¡¡ed when moved to the "down" position

(2to1).

11. TAPE MONITOR SWITCH

When this switch ¡s lifted up to the "deck-1 (4 CH)"

position playback from "TAPE IVIONlIOR-1" is possible,

while at the "2" position "TAPE N/ìONITOR 2" is repro-

duced The tape connector(32) is also f unctionable when

the switch is set at the ".1 " position, i.e,, it f unctions ìn

parallel wìth "TAPE MONITOR 1". In case of 3-head tape-

recorder whìch has playback head for playback in the

course of recording, simultaneous plavback monitoring is

then possible while recording. ln this case this receiver

receives the playback signals f rom either of TAPE

IVIONIIOR-1 , TAPE IVIONITOR 2, or tape connector while

feeding Ìhe recording signals to REC. OUT 1, REC. OUI 2

and tape connector. Remember that this switch must be

set at the corresponding position to which the tape recorder

is connected.

Caution: lf this switch is at the "source" position no

playback possible from tape recorder.

12. VOLUME CONTROL (VOLUME}

A clockwise turn of this control increases volume, while a

counter-clockwise turn decreases and finally cuts out

volume. Thìs knob is of dual concentric construction and

permits separate control of either the r¡ght or left channels;

the outer axis is for the right channel, and the inner axis rs

for lhe left channel. This control usually controls both

channels simultaneously, but you may adjust either channel

by holding one axis while turning the other The click-

sÌoppers are only for the outer axis, i.e., the right channel

13. LOUDNESS SWITCH

Because loudspeakers and ears generally respond less to

extreme high and low (treble and bass) frequencies as

volume levels are reduced, the LOUDNESS switch is

included to boost these frequerrcies and thereby provide

tonal compensation. Whether or not you use th¡s switch

depends upon the levels at which you generally listen, the

kind of speakers you have, the room acoustics and a

number of other variables. Experimantation is the best

guide to using the LOUDNESS switch

14. MUTING SWITCH (MUTING)

Interstation noise which is possible when the tuning point

is drifted can be eliminated by this swìtch in FN/ reception

Use this to cut off ¡nterstation noise or other impractically

weak radio signals. Broadcasts which can be received at the

muting on position are practical for stereo reception. lt is

recommended to keep th¡s switch always "on" except when

a weak siqnals is received

lf tuning of stereo broadcasts only is desired, push this

switch "on" otherwise leave it normally "off" f or reception

of both Stereo and Monaural FIV broadcasts. Also when

this switch is at the "on" pos¡tion, weak signals are com

pletely eliminated

16. LINEAR EOUALIZER

This is a new tone control which provides a tonal

compensation specifically intended for subtly augment¡ng

regular tone controls. w¡th the control in its mid-position,

flat frequency response is achieved. When switched to

either of 2 "up tilt" positìons, the entire response curve ìs

rotated so as to linearly increase treble response while

simultaneously decreasing bass response. Conversely, selec-

lion of a "down tilt" position rotate the response curve in

a clockwise direction and provides a gradual decrease of

treble and a simultaneous increase of bass. This equalizer is

not released even when the Tone Controls Switch is

set at the "tone defeat" positìon. For further details,

refer to the Operation of Linear Equalizer (Page 13).

17. BASS LEVEL CONTROL (BASS)

A clockwise turn of the control boosts the bass response,

and a counter-clockwise turn decreases and cuts the bass.

This control has a click stopper with 11 poìnts. lt yields a

flat frequencV response when set at the centre of the rota

tion angle. You can choose a turnover (roll-off) frequency

of 150H2 or 300H2 with the Selector Switch(18) The Bass

Level Control is of dual concentric construction and

permits separate control of either the right or lefÌ channels:

the outer axis is for the right channel, and the inner axis is

for the left channel. This control usually controls both

channels simultaneously, but you may adjust either channel

bv holdinq one axis whìle turning the other The click-

stoppers are only for the outer axis, i.e., the right channel.

18. BASS FREOUENCY SELECTOR SWITCH

Bass turn-over (roll-off) frequencies can be selected with

this swìtch. When the desired frequency (150H2 or 300H2)

is set by thìs switch, tone control starts to function at

the selected frequency. At the FLAT position, a flat

frequency response is obtained, regardless of the position of

the Bass Level Control(17).

19. TREBLE LEVEL CONTROL (TREBLE)

A clockwise turn of this knob boosts the treble response,

while a counter-clockwise turn decreases the treble This

control is of the same construct¡on as that of the Bass Level

Control, and ìts operation corresponds to that described in

(11 )

20. TREBLE FREOUENCY SELECTOR SWITCH

Function-wise, it is the same as the Bass Frequency Switch

described in (18) Treble turn-over (roll-off) frequencies

can be selected at 3KHz or 6KHz.

21. LOW CUT FILTER

With this switch low frequency range can be cut off at

the rate of 12 dBloct Reduction at th¡s rate can be made

below 70H2. See the f urther details in the "Operation of

Low Cut Filter"

22. HIGH CUT FILTER

Setting of this switch reduces the amount of high frequen-

cies above I KNz ar the rate of 1 2 dB/oct See the further

details in the "Operation of Treble Cut Filter"

23. SPEAKER SELECTOR SWITCH (SPEAKERS}

Thìs receiver offers convenient use of 3 pairs of speaker

systems You can choose independent or simultaneous

driving of 1 or 2 systems among 3 pairs as per the

indication on the panel. When the knob is set at the "B"

posìtion B speaker terminals(29) start to function, and like-

wise at the "A + B" position both A and B speaker

termìnals(29 ) si muitaneously operate.

24. HEADPHONE JACK (STEREO PHONE}

Connection of stereophonic headphone to this jack allows

pr¡vate listening. Output signals are always available irre-

spective of the position of speaker selector switch(23) For

use of stereophonic headphone, however, it is recom-

mended to set the speaker switch at the "off" position

25. MAINS SWITCH (POWER)

Repetition of pressing this knob ensures alternate switch-on

and off.

26. MAINS CORD

For operation of this rece¡ver the mains plug attached to

this cord should be connected to the mains power supply

so u rce.

27. I\4AINS FUSE (U-TYPE AND E-TYPE)

15. STEREO ONLY SWITCH ln the mains power circuit is inserted 5A(U-TYPE) 'or
