Even though musical wave forms are complex, they are
merely a composition of various kinds of pitch components,
each with its own Individual amplitude and phase character
istic. Therefore, in order to have a faithful reproduction of
the musical wave form applied to the speaker system, not
only the amplitude (sound pressure Ieve|)/frequehcy res»
ponse of the speaker system. but also the phase/frequency
reponse, must be flat. Technics has developed a phase»
measurement system which employs a delay unit usmg a
Bucket Brigade Device" This system permits accurate
analySis of the speaker phase, and. as a result, a new cross-
over network and high performance wide»rahge drivers and
their ideal positioning are used to flatten both the amplituder
frequency response and the phase/frequency response
The Technics SB-7000A speaker system has been de
signed to convert musical wave forms applied to the speaker
to sound waves With extremely high fidelity, in other words,
to make the transfer function ol the speaker system is unity.

SPEAKER PLACEMENT

As with any fine speaker system the actual listening enr
Vironment will affect the overall sound quality, A little care
taken in placing the speakers Will assure that the original
sound quality can be realized in almost any listening room.

.The SB-7000A is designed as a floor standing system and
should be placed on a hard (preferably concrete) floor. If
other than a solid floor is used, then a small base or
platform should be constructed of bricks or other similar
material.

OPlacing the speaker in a corner Will tend to emphasrze the
low frequency range, Therefore, place the speaker to a-
chieve the effect of your IndiViduaI preference

.The walls opposne the speakers should be covered in a
soft. sound absorbing material such as drapes.

.To prevent unwanted acoustic feedback between the
speaker and turntable. at high listening levels, it is ad
Visable to provide a very solid mounting surface for the
turntable. This is especially important when the listening
room has wooden floors.

CONNECTING THE SPEAKER SYSTEM

The impedance of this speaker system is 6 Ohms. Be sure
thatthe load impedance of the amplifier. to which this unit is
connected. is rated trom 4 to l6 ohms.

The speaker terminals are color coded and marked ' f

(orange) and "i" (blackl. and are especially designed to
make positive contact With the speaker wire When con»
ncecting to the amplifier. make sure the r of the amp

is connected to the .» " of the speaker and the "i of the
amp is connected to the 7 " of the speaker to assure that

the speakers are working in phase.
Make the connections as shown in figure I

GRILLE INSTALLATION AND REMOVAL

The grilles can be installed and removed as shown in figures
installation. For the upper grille, align the two holes of the
rubber feet on the frame with the projections on the
cabinet, and then push down-ward gently. For the lower
grille, align the four rubber projections of the frame with the
pipes on both sides of the cabinet, and then push gently.
Removal: Grasp the grille frame and gently pull it toward
you.
