SE-99: Precautions for Use
• Do not connect a microphone other than the RE - 99 remote control microphone lor EM-99
condenser
microphonel to the MIC jack on the front panel of this unit.
If you connect another microphone to this jack , noise will be emitted and a breakdown
may occur. Also, automatic sound space compensation measurement and reverbera-
tion time measurement will not be possible.
• The TAPE PLAY terminals at the back of the unit are provided with shorting pin plugs.
These are for reducing noise when nothing is connected to the TAPE PLAY terminals.
When you wish to connect a tape deck to the TAPE PLAY terminals , first remove these
shorting pins.
Do not insert these shorting pins into the TAPE REC or other terminals apart from the
TAPE PLAY terminals because this may cut off all sound from the speakers.
SE-99: Precautions d'utilisation
• Ne pas relier de microphone autre que Ie microphone commandable a distance RE-99
lou Ie microphone a condensateur EM-991 ala prise MIC du panneau avant de I'appareil.
Si I'on relie un autre microphone acette prise, cela engendrera des parasites et on ris-
que de provoquer une panne. De meme , la mesure de la compensation automatique
d'espace sonore et la mesure du temps de reverberation ne seraient pas possibles.
• Les bornes TAPE PLAY qui se trouvent au dos de I' appareil sont dotees de fiches a
broche court - circuitantes. Elles permettent de reduire les parasites lorsqu'on ne relie
pas d'appareil aces bornes. Pour relier un magnetophone aux bornes TAPE PLAY, retirer
tout d'abord ces fiches court-circuitantes .
Ne pas inserer ces fiches
court-circuitantes dans les bornes TAPE REC ou toute borne
autre que les bornes TAPE PLAY car ceci risquerait de couper Ie son des enceintes.
SE-99: Precauciones para su utilizaci6n
• No conectar otro tipo de micf6fono que no sea el micr6fono de control remoto RE-99
10 el micr6fono de electreto EM - 991 en la toma MIC del panel delantero de este aparato.
Si se conecta otro tipo de micr6fono en esta toma, se emitiran ruidos y podria ocurrir
una averia. Ademas, la medici6n automatica de compensaci6n de espacio de sonido
y la
medici6n del tiempo de reverberaci6n no seran posibles.
• Los terminales TAPE PLAY situados en la parte posterior del aparato disponen de clavi-
jas cortocircuitadoras que reducen el ruido cuando no hay nada conectado en los ter-
minales TAPE PLAY. Cuando se desee conectar una grabadora en los terminales TAPE
PLAY,
quitar primero estas clavijas cortocircuitadoras .
No insertar estas clavijas cortocircuitadoras en los terminales TAPE REC , u otro tipo
de terminales que no sean los terminales TAPE PLAY ya que de 10 contrario, el sonido
de los altavoces quedara cortado .

Automatic sound space compensation function
This function uses a computer to analyse the acoust ic chara cteris-
ti cs of your listening room including the frequen cy cha r acterist ics of
y our stereo system, and automatically creates an equalizer curve of
the reverse cha r acte ristics , resulting in a flat frequency response .
Measu re the acoustic characteristics of your listening room as fo ll ows .
1. Insert th e plug of the remote control microphone ( or condenser
microphone) into the MIC jack , and set the power sw i tch to ON.
2. Set the microphone at the listening point so that it fac es a poi nt
mid-way between the l eft and right speaker systems .
3. Set the volume control of the amplifier to the normal listening level.
4. Press the light pen against the COMPENSATE SOUND SPACE in-
dicator and press the switch . or press the COMPENSATE SOUND
SPACE button on the remote contro l microphone . The COMPEN-
SATE SOUND SPACE indicator will flash.
5. The line
input will be automatically cut off . and pink noise will be
emitted first from the left speaker system.
The level of the pink nois e will be low at first. then gradually in-
crease until it reaches the necessary level for measurement . At
this point . the pink noise will be. emitted ' five times in 0.4 second
bursts at intervals of 0.5 seconds.
Measure
thi s pink noise using the microphone, and take the aver-
age
of the measured values as the characteristics of your list en-
ing room.
If the necessary level for measurement is not obtained even when
the output level of the pink noisse is maximum , the UNDER LE V-
EL indicator will flash, and an electronic tone will be emitted .
In this case, increase the setti ng of the vo lume control on the am-
plifier.
6. Next, measurement of the right channel will take place in the same
way.
7. The reverse characteristics of the averaged sound space frequen cy
characteristics will be automatically memorized as flat data in the
flat memory circuit. and the co rresponding equalizer curve will be
set.
At this time, the FLAT i ndicator will light .
The memorized flat data can be recalled by pressing the light pen
against the FLAT indicator and pressing the switch, or by press-
ing the FLAT button on the remot e cont rol microphone. When
this is done. the FLAT indicator wi ll light.
00 not perform sound space compensation at the lowe st frequency
of 16 Hz and the highest frequency of 32 kHz. Set these frequen-
cies
to 0 dB. This is because for a normal listening room and speak-
er
system there is a danger of destroying the woofer and tweeter
if an attempt is made to perform compensation at these fre-
quencies.
If the deviation in level between each band is within 12 dB, set
the flat data in 1 dB steps (±6 dB), and if the deviation exceeds
this value, set the flat data in 2 dB steps (± 12 dBI.
If the deviation exceeds 24 dB (± 12 dB). the FLAT indicator will
flash for 10 seconds. indicating that the compensated frequency
characte r ist ics are not perfectly flat. however the set data will be
memorized
as flat data.
The
flat data witl be retained in the flat memory circuit until the
next sound space measurement is performed.
To inter rupt measurement . press the light pen against th e RESET
i
ndicator and press the sw it ch. or press the RESET button on the
remote control microphone.
Remember always to set the power switch to OFF after . having
used the microphon e.
• Note that if there is external noise or air conditioning noise, ac-
curate data cannot be created.
If the magnitude of the noise is large. measurement may some-
times be impossible .

COMPENSATE
NOISE REC
Automatic tape characteristic compensation
function
The frequency characteristics obtained during re cording and playback
using a tape deck sometimes have marked peaks and troughs due
to the frequency characteristics of the tape deck or the tape used.
This
unit can be used to analyse the peaks and troughs in the fre-
quency characteristics and automatically set an equalizer curve hav-
ing reverse characte ri stics, enabling flat frequency characteristics to
be obtained.
1. Operate the tape deck and
start recording.
2.
Pr ess the NOISE REC switch ON (the indicator above the switch
will light).
Pink noise will be output from the TAPE REC terminal, and after
the lapse of the period which is necessary for measurement (ap-
prox. 10 seconds), an electronic tone will be emitted.
3. When the electronic tone is emitted, stop recording on the tape
deck. then pre
ss the NOISE REC switch OFF (indicator will goout).
4. Press
the 1 or 2 TAPE MONITOR sw it ch ON (the indicator above
the switch will light). Press the switc h corresponding to the ter-
minal to which the tape deck is connected.
5. While playing back recorded pink noise, either pre
ss the light pen
against the COMPENSATE-TAPE indicat
or and press the switch ,
or press the COMPENSATE-TAPE
button on the remote control
microphone. The COMPENSATE-TAPE indicate will flash.
Next. set the reverse recording
or playback characteris tic s as flat
data using the same procedure as that used for automatic space
sound compensation.
* You can memorize flat data in the same way as data for a normal
equalizing curve
in the user's memory circuits (1 to 5) .
* Because of the characteristics of the tape, 16 Hz and 32 kHz are
set
to 0 dB without applying compensation.
12
If you change the tape deck or use a different type of tape, per-
form measurement again.
In the following cases, the UNDER LEVEL indicator will fla sh and
an e
le ctronic tone will be emitted.
-If the COMPENSATE-TAPE mode is activated before pink noise
is emitted. In this case, repeat step 5.
-If the pink noise recording le vel is low .
In this case, raise the recording level. and repeat steps 1 to 5.
Note
that if the NOISE REC swi tch is set to ON . the COMPEN-
SATE TAPE mode cannot be activated.

'Reverberation time measuring function
This unit is pr ov id ed wi th a function which indicates reverberation
time
as r ea l time for each frequency. This func ti on allows you to ob-
tain a near-optimum reverberation time by rearranging furniture and
carpets, etc., in your listening room while repeating measurement
s.
Measure the reverberation time u si ng the following procedure.
1. Insert the plug
of th e remote control microphone (or condenser
microphone) i
nto the MIC jack, and se t the power switch ON.
2. Set the microphone at the listening point so that it faces a point
mid- way between the left and right speaker systems.
3. Set the volume control of the amplifier to the normal listening
le ve l.
4. Press the li ght pen aga i nst the REVERB TIME indicator and press
the
switch , or press the R. TIME button on the remote control
microphone. The
RE V ERB TIME indicator will flash.
5. The line
input will be automatically cut off, and pink noise will be
emitted from the speaker systems
of both channels.
The level of the pink noise
wi ll be low at first, then gradually in-
crease until it reaches the necessary level for measurement. Then,
after a fixed interval, the level
will be measured and the computer
will calculate the interval nece ss ary for th elevel to be attenuated
by 60 dB.
This measurement
will take place once for each fr eq uency except
16 Hz and 32 kHz, that is, a total of 10 times, and during each
measurement the
re verberation time will be displayed in steps of
0.1 second on both channel displays.
6. Upon completion
of measurement, the REVERB TIME indicator will
stop flashing and gl
ow steadily.
If the necessary level for measurement is not obtained even when
the
output level of the pink noise is maximum, the UNDER LE V EL
in di cator will flash, and an electronic tone will be emitted.
Like the data for a normal equali
ze r curve, this reverberation time
data can
be memorized in the user's memory circuits (, to 5).
To interrupt measurement, press the light pen against
the RESET
indicator and press th e swi tch, or press the RESET button on the
remote control microphone.
Remember al
ways to set th e power swi tch to OFF after having
used
the microphone.
* Note that if there is external noise or air conditioning noise, ac-
curate data cannot be created.
If the magnitude of the noise is large, measurement may some-
times be impossible.

Adjusting reverberation time
The reverberation time of the listening room is one of the major fac -
tors which influence the reproduced sound quality. If the reverbera-
tion time is too short, the sound will lack warmth , while if it is too
long, the sound will be " muddy". The ideal reverberation time is be-
tween about 0.3 and 0.8 seconds, depending on the size of the room.
Also, it should be the same for all frequencies .
Reverberation is caused by certain frequencies being absorbed and
accentuated due to the dimensions and structure of the room when
the sound from the speakers is attenuated while being reflected off
the walls and ceiling. Consequently, the necessary countermeasures
far reverberation will vary depending upon the condition of the listen-
ing room. Try improving the reverberation time while referring to the
following.
A) High range
Generally, most audiophiles tend to aim for sound with clearly de-
fined contours, and hence prefer a listening room having a short rever-
be ration time. To this end, it is normal practice to use a large quantity
of sound absorbing material in the room (curtains, carpet, etc.) In
this case, there is no problem if all frequencies are absorbed uniformly ,
however in many cases only the high frequencies are absorbed, result-
ing in a dull sound.
In such a case, the reveberation time for the high requencies can be
extended by using curtains and carpet with short hairs, or by placing
reflecting panels in front of the curtains in the rooms.
If the reverbeation time in the high range is too long, the sound will
not be adversely affected to any great degree. It can be improved,
however, by using sound absorbing curtains, etc .
B) Middle range
If the reverberation time in the middle range is too short, the sound
"penetration" will be degraded, and for the same output power the
volume wilt tend to be low .
If the reverberation time is too short, objects in the room will often
resonate in this range. In such a case, these objects must be found
and removed . This can be done by removing objects of at a least
a certain size from the room one at a time, and repeating meas-
urements.
Conversely, if the reverberation time in the middle range is too long,
the sound will reverberate excessively. In this case, standing- waves
may sometimes be set up. This can be overcome by placing a box
of about one cubic meter containing sound absorbing material (glass
wool, etc.! in each corner of the room.
C) low range
The reverberation time in the low range is nearly always too long in
the average listening room, and a satisfactory solution is rather
difficult. To completely overcome this problem, it is necessary to
modify the walls of the room. A simpler method which will provide
some degree of improvement is to use larger quantities of sound ab-
sorbing materials
than are necessary to shorten the reverberation ti me
in the middle range.
