A built-in 1/3-octave parametric equalizer is also
included, allowing for three bands of independent
adjustment for the front, rear and center channel
speakers. There are settings for frequency, gain,
and Q (how the slope of the adjusted frequency is
affected). Either pink noise or audio material can
be used to set the EQ.
Also included are seven different DSP surround
settings (such as Club, Theater, etc.) to help cre-
ate a bigger sound stage, as well as a digital time
alignment option to set speaker delays to com-
pensate for sonic discrepancies caused by the
vehicle’s interior.
The DVH940 also includes Dolby Pro Logic II
decoding. Dolby Pro Logic II is the first processor to
produce 5.1 surround sound from ANY stereo
source, including FM, CD, MP3 or VHS movie audio
tracks. Now you can experience true “you are there”
audio performance. Dolby Pro Logic II in the
DVH940 generates front, center, surround, and sub-
woofer outputs for a true mobile surround sound
system.
For audiophile sound quality, the DVH940 uses 24-
bit D/A converters for low distortion audio and
delivers the 5.1 surround signals through 4-volt, 6-
channel RCA line-level outputs.
Surround Sound Technologies
5.1-Channel Dolby Digital/dts Surround
Dolby Digital and dts provide three channels of front
sound, together with two rear surround channels and
a dedicated low frequency channel for a subwoofer.
This combination can reproduce the dynamic sound
field of a movie theater in the confined space of the
average vehicle.
Dolby Pro Logic II
While standard Dolby Digital and dts require spe-
cially encoded software to reproduce 5.1-channel
surround sound, Dolby Pro Logic II can create a
complete 5.1-channel surround sound effect from
ANY 2-channel source. The sound decoding tech-
nology can be found in Clarion’s DXZ945MP, a
high-end source unit featuring Clarion’s exclusive
AC Processor III technology.
If your favorite movie is only in stereo, or you are
listening to CDs, MP3s or even Sirius Satellite
radio, Dolby Pro Logic II will give you a full 5.1-
channel surround sound effect. It features a phan-
tom center-channel mode that simulates a center
channel, creating a quasi 5.1-channel sound field
from just the four standard speakers of a car audio
system.
The DVH940 Dolby Digital/dts/Dolby Pro
Logic II Processor
The DVH940 incorporates Dolby Digital, dts, and
Dolby Pro Logic II processors, a parametric equal-
izer, crossovers, digital sound field settings and
digital time alignment adjustments
The DVH940 processor has selectable crossovers
for the front, center, rear and subwoofer channels
at 50/80/120Hz. To aid in setting proper speaker
levels, all channel gains are independently
adjustable using a built-in pink noise generator for
proper level setting. Along with the adjustable gain
settings, the center and subwoofer channels’ vol-
ume can also be adjusted separately to allow for
different source material.
