Dolby Pro Logic

This state of the art Dolby Pro Logic mini system
enables you to experience and enjoy a Home
Cinema sound ambience.
Dolby Pro Logic is a coding system that enables
a set to decode 4 sound channels out of a
normal stereo signal: the center channel for
picture related sounds, both front left and right
channels for stereo sounds and one surround
channel for the rear to bring room and depth to
the scene.
The surround signal is reproduced by two
speakers placed towards the rear of the listening
area. Although the surround signal is mono, a
pair of speakers is necessary to produce the
correct diffused sound field.

Dolby Pro Logic manufactured under license from
Dolby Laboratories Licensing Corporation.
DOLBY, the double-D symbol

and ‘PRO

LOGIC’ are trademarks of Dolby Laboratories
Licensing Corporation.

General hints for speaker positioning

Avoid positioning the speakers in a corner or on
the floor, as this will boost the bass tones too
much. Placing the speakers behind curtains,
furniture etc. will reduce the treble response, thus
reducing the stereo effect considerably. The
listener should always be able to ‘see’ the
speakers.
Each room has different acoustic characteristics
and the positioning possibilities are often limited.
You can find the best position for your speakers
by following the picture on the right. The
speakers should always be arranged as
symmetrically as possible in the room.

DOLBY PRO LOGIC

Setting up the Dolby Pro Logic system

A full Pro Logic system needs 5 speakers that should
be connected and positioned as illustrated below.

Positioning the center speaker

The center speaker should be placed in the center
between both front speakers, e.g. underneath or on
top of the TV. The best height for the center speaker
is at the height of the listener’s ears (while seated).
Note: to avoid interference with the TV picture, use
only a magnetically shielded center speaker.

Positioning the surround speakers

The surround speakers connected to the

SURROUND L

terminals of the amplifier should be on the left and
the surround speaker connected to the

SURROUND

terminals of the amplifier on the right side of the

listener in the room.
The surround speakers should face each other and
be in line with, or at most 1.5m behind the listener.
