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 sophisticated 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!

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 movement

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, exceeding

it

is recommended

to

have

the

needle's swing

on this

meter.

ln

case when

of

FI\4 reception such signals as cannot be cut

off the

muting switch(14) is

at the

"on"

position

are used as stereo reception.

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.

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 clicksÌoppers 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

15.

STEREO

ONLY

SWITCH

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 clickstoppers 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

INSTALLATION

While the

R-1

500 Receiver has been designed for maximum ease of installation and operation, we strongly suggest you read this section through before proceeding to connect and operate the unit.

Because the

B-1500 incorporates manV technical and operating refinements, it may be a bit different from equÌpment you have used in the past.

PLACEMENT

AND

MOUNTING

The

R-1500 may be placed in virtually any convenìent location, keeping in mìnd the necessity of connecting cables to your speakers and an antenna for

FM.

Because of its advanced solid-state construction, the unit produces little

heat.

But certain minimum ventilation requirements are still necessary

to

provide optimum operation:

When the

R-1500 is placed on an open shelf in a bookcase or cabinet (mounted in its integral metal case or with the accessory furniture case) about 10 cm of freespaceshould be allowed above it.

POWER REOUIREMENTS

AND

MAINS

CONVE

NIENCE OUTLETS (E.TYPE, U-TYPE)

The

R-1500

Receiver operates on the mains power only

100-125, and 210-250 volts, 50-60H2, consuming 350 watts maximum at full power output.

Three convenience outlets are provided on the rear panel to supply the mains power for additional components suÇh as automat¡c or manual turntables, tape recorders, etc.

The mains cord of a turntable should be connected to one of the unswilched outiets, to permit it to rotate f u lly before turning on.

The mains cords of other components can be connected either to the sw¡tched outlet, and they will be shut off when the receiver is turned

off.

Not more than 100 watts outlets, totai should be drawn from the unswitched nor the switched

outlet.

(lf in doubt about the wattage drawn by additional components, check the ratings on their rear panels, or in their manuals, Automatic turntables, for instance, generally draw from

20-50 watts.) with the R-1500.

For

FlV, a folded dipole, available from your dealer, is generally adequale. This section will tell you how to connect them.

AM

ANTENNA ln all but remote rural locations, the special fold out ferrite core antenna mounted on the rear of the receìver provìdes excellent AIV reception. For the best results, make certain that this antenna is folded out away from the chassis to its maximum extens¡on. lf an external antenna is required, connect

a

length of wire (any type will do) to the

AM

ANTENNA Ìerminal on the rear panel.

FM ANTENNA

SPEAKER B SPEAKÊR

LOUD SPEAKERS

The

R-1500 Receiver is designed to drive

3 pairs of speakers, used either separately or 2 together.

Because of its high output power, two pairs of even the lowest-efficiency speaker systems may be used together without fear of placing too heavy a demand upon the unit.

Although almost any type of wire may be used to connect speakers to the receiver, it is recommended that you use standard guage rip cord.

For runs over 15m(50ft), heavier gauge rip cord should be used if possible.

Whatever thickness of wire you choose, pick the type where you can distinguish one lead from another, either

by

conductor color, a ridge running along lhe insulation of one conductor,

or

by a colored cord under the insulation.

This

will

help you hook up the speakers correctly.

PLEASE

NOTE

(1)

No more than

1.5cm(1 l2"l of wire should be bared for hookup, since longer bared lengths may produce a short circu¡t.

(21

Twist

all

strands of expose'd wire tightly.

Loose strands may cause shorts.

Connect the 'COM' terminal of each speaker to the appropriate black

SPEAK-

ERS terminal on the rear o1 the receiver by pushing on the terminal and

Inserting the bare wire in

the

hole thus exposed.

Make sure the wire does not contact the chassis or another terminal,

to

prevent shorts.

Then connect the other speaker terminal to the appropriate red

SPEAKERS terminal of the receiver.

To

connect a single pair of speakers, ccinnect the wires from from the left speaker (as viewed

the

listening position) to the

"L"

"R"

A

SPEAKERS terminals of the receiver.

The 2nd and

3rd pairs of pseakers can be connected si milarly to

SPEAKER PHASING

To enjoy good stereo reproduction, it is necessary that the

two

stereo speakers in

any

location work as

a

team,

'pushing' and

'pulling' the air in unison.

Otherwise, lowpitched sounds will sound weaker than they should, and the stereo effect at higher frequencies

will

become indistinct.

To connect your speakers for proper stereo effect

(this is called

"phasing"), proceed as follows:

Play

an

FM program with the

Mode

Switch

in

MONO position.

lf

the low bass notes sound normal, the speakers are properly phased. lf they sound th¡n, or weak, the

7

8 speakers are out of phase.

Should thìs occur, turn off the receiver and carefully reverse the connections at either one of the speaker

FOR

CORRECT

PLAYBACK

TINPUTS (Connectìon of input

Equipments)

Check f irm connection to the receiver's input terminals of output terminals of record players, tape-recorders etc. lf no playback sound comes from speaker systems, the receiver may be, at first, suspected

to

be defective, so be sure about firm connection between arm and cartridge and also firm fixture of cartridge to the shell.

¡OUTPUTS

(Connection of

Speaker Systems)

Check firm connection between receiver and speakers. The right-hand speaker viewed from the l¡stener's position must be connected to the "RlGHT" terminals of the receiver, while the left speaker to the

"LEFT" terminals.

Be careful about the matching phase

of

left and right speakers. lf mismatched, playback sound does

not

come from the centre of both speakers even if the mode selector ¡s set at the

"l\4ONO" position, and

in

the case

of

stereophonic playback, faìthful reproduction

ìn low frequency range cannot be expected.

Be sure that the speaker selector switch corresponds to the speaker terminals to wh¡ch the speaker is connected.

TMAINS

SOURCE (Connection

to

Mains Source)

Check whether the mains plug of receiver is firmly connected to the mains power source, and whether the dial scale lights up when switched on. ln case the dial scale does

not

light up even if the electricity is fed to the receiver, check whether the mains fuse is blown. Affirmalively change the fuse ascertaining the real cause of blow and giving necessary treatment.

Replacement of fuse must be done after the mains cord is unplugged from the mains power supply point.

OPERAT¡ON

PLAYBACK FROM RECORD

DISC

ICONNECTIONS

Generally a record player consists of a turntable ensuring constant rotation of the record disc a pick-up

(cartridge) whose stylus

(needle) traces the sound groove of the disc converting the physical signal of the record sound into the electric signal, and the arm which holds this cartridge.

The player has

2 cords with pin plug at its end for both right and left channels. Connect the pin connectors to the input terminals of this receiver

IPHONO-1(37) or

PHONO-2(37)].

A

probable earth lead

of

player may be connected to the

GND terminal(4O) of this receiver.

A mains cord of the player to drive its motor may be connected to lhe convenient extra mains outlet(28)

(E and

U type only).

This receiver is provided with 2 input terminals

(PHONO-1

and

PHONO-2) to be selected by

the

input selector switch(

1 ), which is useful for comparison test of 2 pickups or using

2 record players.

For use of

1 player either of

2

input terminals can be selected.

ISIGNAL

PATHS

Put the disc on the turntable, switch on the phono motor, and set the stylus on the groove of disc.

Then recorded signals begin to be fed to the receiver.

First, signals fed to the receiver through PHONO terminals are brought to the equalizer section, where recorded signals are equalized and restored to the original frequency curve. lncidentally this equalizer curve has been standardized to the RIAA curve.

The equalized signals are then fed to the input selector swilch

(function switch). lf th¡s switch

¡s not set at the correct position

of

PHONO, the signals are blocked here and no more advance is possible.

Then the signals are divided into

2

channels, one line to the recording output terminal, and the other to the tape monitor switch,

Then the tape reprint switch which is effective on both channels.

lf the monitor sw¡tch(11) is set at the

"source" position the signals are sent to the mode selector switch, and volume control, but if at the

"deck-1

" or "deck-2" position the tape monitor terminals start to f unction and lhe signals are stopped at this

point.

Except when the tape playback is made by tape monitor terminals, the monitor switch must be kept at the "source" positon.

But when the input signals are fed to

PHONO

or

AUX terminals recording output is always obtainable regardless of the positíon of the monitor switch.

Then the signals are sent to lhe volume control through the mode selector, f ilters, and loudness control.

lf

the volume knob is turned to the extreme end of counter-clockwise direction, the signals cannot proceed ahead. lt is necessary to set this control at the optimum volume.

Such controls as linear equalizer, low-cut filter, high-cut

filter,

loudness, and tone controls are for flexible and diversified adjustment of playback sound and do not block the signals completely.

Then the signals reach the speaker switches amplif ied by the main amplifier.

Sound playback from speaker systems is thus realized if the speaker switch corresponding to

the

speaker terminals to which the speakers are connected is set at the correct position.

The above is the feeding path of

PHONO signals starting from input terminals to the speaker systems.

Difficult as it may sound you can easily understand it from the attached block diagram. For your pleasant command of this receiver we recommend you to bear the block diagram in your mind.

TPLAYBACK

PERFORMANCE

Now put a disc on the turntable for playback performance.

As the volume control is turned clockwise from the cut position, playback sound comes out from speakers.

As explained in the paragraph of

Sìgnal Paths the sound playback

is

possible regardless

of

the posìtion of

[Vode

Selector etc. as far as these essentìal controls are set at the correct position such as Input

Selector Switch(1),

Tape Dubbing

Switch(.1

0), lVonitor

Switch(11),

Speaker

Selector Swjtch(23) and

Volume

Control('l

2).

Now all preparations have been completed. Check if the volume levels

on

both right and left speakers are identical. lf deviated adjust it by the

Volurre

Control.

For stereophonic playback see to

¡t that the lVode Selector

Swìtch

ìs kept at the "stereo" position, otherwise correct stereophonic playback is not feasible.

PLAYBACK

OF AM/FM

BROADCASTING PROGRAM

Selection of the input selector(

1 position ensures playback

) at the AM or

FM of

AIV or

FM broadcasting programme, lf you want you can connect other tuner

(AM, FM,

LW or

SW etc.) to one of the AUX terminals of this receiver. ln this case the selector must be set at the corresponding position.

As shown in the block diagram the input signals from the tuner sect¡on on AUX terminals are directly fed to the lnput Selector

Switch.

Afterwards the signals trace the same blocks as explained in the paragraph

of

Playback from

Record Disc and are reproduced from the speaker systems. Both for

FM stereophonic and monaural broadcasting the lVlode

Selector

Switch can be set

at the

position of "FfVl", for such accommodation to the ìnput source can be made in the tunersect¡on. In case weak FM stereo is received and you feel ìt noisy, set the l\4ode

Selector

SwiÌch(

) at

the

"mono" position for better reproduction. ln case of

AM/LW programme from other tuner there is possible trouble

Usually

the

volume level of both channels is adjusted identical at the straight engraved llne on the

lf a programme source had deviation of the volume level between 2 channels, establish correct balance with this balancer.

ITONE

CONTROLS

The ultimate purpose of the audio system is

to

make the high fidelity reproduction of programme sources.

The reproduction conditions and circumstances do not always match with record¡ng conditions, and it is impossible to reproduce

the

same sound with

the

original one

Also there is no objective standard to judge good sound

from

inferior one.

The

only

possible solution is for every listener own

taste.

to create hls favorite sound according to his lt is therefore very important that the audio system offers such facility

to

permìt flexible controls for creation of the best sound.

TH is receiver is equipped wìth various tone controls for subtìe and minute control of the reproduced sound such as Bass

Level Control(17) and Treble Level Control(19). and Liner

Also this can be used as an auxiliary control for Treble Level Control.

IOPERATION

OF

LOUDNESS

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 frequencies and thereby provides tonal compensation.

Whether or not you use this 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. Experimentation is the best guide

to

using the

LOUDNESS switch

ITHE

LINEAR

EOUALIZER

Although recordings are equalized in accordance with

B iAA standards, it is quite common to encounter variations

ìn overall tonal balance from one record¡ng to the next.

In addition, differences in listenìng environment and room acoustics often require subtle degrees of tonal compensation that conventional tone controls cannot correct because of their wide range and overlapping crossover characteristics.

THE LINEAB EOUALIZER control provides a new form of tonal compensation specifically intended for subtly augmenting regular tone controls. With the control in its mid-position, f lat f requency response is achieved.

Switched to either of the two "up-tilt" posÌtions, the entìre response curve ls rotated about a

1

KHz f ixed axìs so as to linearly increase treble response whìle simultaneously decreasing bass response.

Conversely, selection of one of the "down-tilt" positions rotates the response curve in a clockwise response direction, providing a gradual decrease and simultaneous increase of treble of bass response.

Degree of slope for either positive or negative settings has

13

14 been carefully preset, and

the

overall response curve maintains complete linearity from

50Hz to above 10KHz, unlike the curvature in response normally associated with ordinary tone

controls

Specif ically, when the control is turned

to

the first

"up-tilt"

position it

w¡ll

decrease bass

and

increase

treble

by

15dB

at

'l

00Hz

and

l0KHz respectively, while selection to the second

"up-tilt" posìtion will result in a 3dB cut and boost at these same frequencies.

Selection

of

the fìrst "down-tìlt" position

wìlì

decrease treble and increase bass frequencies,

by

i

5dB at the same reference while the second

"down-tilt" position provides

3dB of boost (at

100H2) and cut

(at

10KHz)

Combined use

of

the LINEAR

EOUALIZEB and convenlional tone controls provides a degree of tonal flexibility which cannot

be

achieved

with

any

other tone control arrangement presently available
