About Time Correction
The distance between the listener and the speak-
ers in a car vary widely due to the complex
speaker placement. This difference in the dis-
tances from the speakers to the listener creates a
shift in the sounds image and frequency charac-
teristics. This is caused by the time delay between
the sound reaching the listener's right versus the
left ear.
To correct this, this unit is able to delay the audio
signal to the speakers closest to the listener. This
effectively creates a perception of increased dis-
tance for those speakers. The listener can be
placed at an equal distance between the left and
right speakers for optimum staging. The adjust-
ment will be made for each speaker in 3.4 cm
steps.
About The Crossover
This unit is equipped with an active crossover. The
crossover limits the frequencies delivered to the
outputs. Each channel is controlled indepen-
dently. Thus, each speaker pair can be driven by
the frequencies for which they have been opti-
mally designed. The crossover adjusts the HPF
(high pass filter) or LPF (low pass filter) of each
band, and also the slope (how fast the filter rolls
off the highs or lows).
Adjustments should be made according to the
reproduction characteristics of the speakers. De-
pending on the speakers, a passive network may
not be necessary. If you are unsure about this
point, please consult an authorized Alpine dealer.
