DSO26

Descrizione
Digital System Optimizer DSO26 is a digital pro-
cessor with high audio quality thanks to the dou-
ble precision signal elaboration offering a dy-
namic range greater than 110dB. DSO26 pro-
vides 2 inputs and 6 outputs
to operate in the following modes: 2x3-way, 4+2-
way, 5+1-way – with a mono sum output available
– or 6-way. There are 30 bands of parametric
equalization available, each of them allowing a
gain from +15 to –30dB in a range from 20Hz to
20kHz, with a Q that can be adjusted from 0.4 to
128. All parameters feature fine adjustment with
1/36 octave frequency steps and gain increase
at 0.1dB steps and 100 Q settings.
Each parametric section can be set as a
shelving filter. All outputs are provided with a
high performance limiter, with attack, release
and threshold control parameters. Every output
features variable high-pass and low-pass filters
of 12, 18 or 24 dB per octave of Butterworth,
Bessel or Linkwitz-Riley type. Independent con-
trol of each filter allows the creation of asym-
metrical crossover bands. Delay lines of up to
650ms can be set independently on every out-
put, with fine adjustment by 2.6µsec minimum
steps. DSO26 includes presets for Proel Sys-
tems and will let you memorize personal settings.
Its software can be updated through its RS232
port. The LCD shows all parameter information.
The headroom of both channels can be moni-
tored with the LED bars. Interface software for
Windows 9x/Me/2000/XP, updated presets and
the processor manual (which we strongly rec-
ommend reading) are available on our web site:
sound.proelgroup.com.

Engineering specifications
The digital processor should have 2 inputs and
6 outputs. Operative modes should allow the
system to work as 2x3-way, 4+2-way, 5+1-way
or 6-way with a mono sub out possibility. There
should be 5 parametric equalization sections for
each output. Every input/output should have:
up to 650 ms delays in 2.6µs steps, a limiter
with attack, release and threshold controls. The
input signal level should be displayed on LED
bars and the parameters should be displayed
on a backlit LCD. The digital processor should
at least feature the following specifications: fre-
quency response: 0.5dB 20Hz-20kHz; dynam-
ics: 110dB20Hz-20kHz, un-weighted; paramet-
ric filters: a total of 30 digital sections, with
+15dB to -30dB gain in 0.1dB intervals; central
frequencies: 20Hz-20kHz, in 1/36 octave steps,
filter Q from 0.4 to 128.
should be coupled through electronically bal-
anced XLR connectors. The processor should
be a 1 19" rack unit with supply voltage variable
from 90VAC to 240VAC 50/60Hz. The digital pro-
cessor should be a Proel DSO26.
