R-DES (Rocket Digital Equalization System) is an external five band
electronic parametric equalizer with software and PC interface. R-DES is
normally included with the UFW-12 but is currently back-ordered, so call or
check the website for availability. Customers who order the UFW-12 during
the back-order period will receive R-DES (shipped free) when it becomes
The latest version of R-DES includes the following revisions: 1) The band
originally dedicated to the Subsonic Filter has been replaced with an
additional PEQ band (for a total of five PEQ bands); 2) a gain dial has been
added to the GUI control panel; and 3) the system now features unity gain.
R-DES package includes the hardware box, a USB 2.0 PC interface cable, a
wall wart for AC power, and a software installation disc. The small R-DES
hardware box goes between the subwoofer pre-out on your SSP or receiver and the
line level input on the UFW-12, so you will
need two subwoofer cables to make the connections. The hardware box has dual
parallel inputs and outputs, so it can accommodate up to two subwoofers (but
they cannot be EQ'd separately).
Virtually an unlimited number of PEQ curves can be stored in the R-DES
software on your PC, and four PEQ curves can be saved to the hardware unit. These
curves are selected via a push button on the front panel, and there is also
a Bypass setting.
using a PEQ requires that the owner measure the in-room frequency response
of the subwoofer. AV123 makes this easy by offering an Onix Graph Paper
program and a CD with test tones. The Graph Paper software even includes the
C-weighted correction factors for the popular Radio Shack SPL meter. There
is also an on-line R-DES tutorial to help out first-time users.
Overall, R-DES is a very slick product that works with your PC to considerably ease
and streamline the traditionally tedious process of using a manual PEQ. It
adds an extra dimension of equalization capability not found on any
subwoofer in this price range, and with five bands it can tame the toughest
room acoustics. With four memory settings, you can select custom EQ curves
for different types of music and movies.
