is bidirectional speaker outputting the same sound in two

directions, for example forward and backward.

An arrow for matching the phases (



) is marked on a

dipole speaker. Place the surround speakers (a) so that

their arrows ( ) point to the TV and the surround back

speakers (b) so that their arrows ( ) point to each other.

½

Phase: A waveform position in one cycle (0 to 360 degree) of sine

wave. If the phases do not match due to mistake in speaker distance,

installation angle or positive/negative of wiring, sound image and sound

field may be unclear or hard of listening.

Connecting a Power Amplifier

You can connect a power amplifier to the unit and use the

unit as a pre-amplifier in order to produce a large volume

that cannot be output with the unit only. Connect the

speakers to the power amplifier. For details, refer to the

power amplifier's instruction manual.
