Thank you for selecting theTechnicsLinear Phase
Speaker System SB-ElOO. To obtain maximum
satisfaction from all of its many features as well as
the longest possible service, be sure to first read
these instructions carefully,

No matter how complex musmal wavelorms may be, all are
composed of frequency components with their own amplitude
and phase in order to faithfully reproduce such musical wave-
forms, not only must the amplitude (sound pressurei/frequency
response be flat, the phase/frequency response must also be
linear. At Technics we have, by using BBD (Bucketrarigade
Device) technology, succeeded in developing our own unique
phase-measurement system. As a result of long and deep re-
search into the phase characteristics of speaker systems, and
by developing wide-range, high-performancespeakerunits and
arrangingthem in theideal position, and furthermore bydesign-
ing a new crossover network, we were able to successfully pro-
duce a true linear-phase speaker system,

lNSTALLATlON OF YOUR SPEAKER SYSTEM

The sound reproduced by a speaker system is easily influenced

by such factors as room acoustics and the place where it is

placed in the room. Before finally deciding upon the place
where the speaker systems are to be placed, please carefully
read the following information.

a in general, if a speaker system is placed on the floor, near a
corner or near a wall, the level of the bass sound will be
increased by the reflections of the sounds from the wall and
floor. Consequently, it is possible to adjustthe bass sound to
some extent by changing the distance between the speaker
systems and the wall and/orfloor. Determine the location of
the speaker systems which gives the best sound reproduc-
tion, therefore, depending upon the actual conditions of the
room in which they are to be used

- if the speakersystem faces toward a hard wall ora glassdoor
or window, itis recommended thatcurtains crsimilarmaterie
al be used in order to prevent undesirabie resonance and
sound reflection, especially of the treble sound.

0 Vibrations from the speaker systems may be transmittedjo a
record player, causing acoustic feedback (howling). For
best results, the speaker systems should not be placed near
the record player, and should never be placed on the same
table or shelf as the record player. it is often very effective, in
order to prevent howling", to place a thick piece of felt
beneath the speaker systems and the record player

CONNECTING THE SPEAKER SYSTEM

0 Be sure to turn off the power of the amplifier before connect-
ing the speaker systems to it

o The impedance of this speaker system is BohmsBesure that
the load impedance of the amplifier to be used is 4 ~ 16 ohms.

0 The input terminals of this unit are on the control tower on
the top of the enclosure, There are located the system
input" terminals and the multi-amp system" terminals.
When this speaker system is used as an ordinary speaker
system, connectthe speakerconnection wirestothesystem
input" terminals. If this speaker system is used with a multi-
amplifier system, connect the speaker connection wires to
the multiamp system" terminals. Be sure to read the in,
structions (below) concerning use with a multi-ampiitier
system.

0 The upperterminal of each pairofterminais is positive, and
the lower is negative (indicated + and 7). When connecting
speaker connection wires from the amplifier, be sure that the
tall and right connections and the plus and the minus con-
nections are made correctly.

When speaker connection wires are connected to the system

input" terminals, make the connections as shown in figure 2a.

1. Strip about 10 mm (i/2") of the insulation from the wire, and
then twist the core,
