Acoustic Phase Shift
The ESX-VISION VE Series Amplifiers have an integrated channel separated Phaseshift Control.
By controlling the phase, perfect soundstaging is realisable.
Conventionally Systems
without Acoustic Phase Shift
In vehicles the listener is located in
principle outside the acoustical
center. The stereo sound seemed
to diffused and unnatural. The
sound doesn't seem to be well-
defined because the distance
between the listener and speakers
is much shorter on the left side.
Band Pass - Function (Subsonicfilter)
By using the HIGH PASS / SUBSONIC controller you are able to adjust the lower threshold frequency of the subwoofer
signal. The upper threshold frequency is adjusted by the LOWPASS Controller. Both filters together generate an
spectrum which is called BAND PASS-SIGNAL. Now the frequency signal looks figurative like a trapeze which harmonize
very well with an subwoofer enclosure and disturbing frequencies in the lowpass-range are limited.

Car Audio Systems with
Acoustic Phase Shift
By changing the Phase you can
virtually move your speakers to
the left side and the signal arrives
later, for instance on the left ear of
the listener and the acoustical
center stage is recovered. The
sound characteristics will be
played acoustical correct.
