What is R-DES?
R-DES is a programmable control to improve the response of your
subwoofer(s) in your room. There are two components to the R-DES
system. The first part is a small hardware box that has stereo RCA
inputs and outputs. You can use one set for a single sub or both
if you have stereo subs. This box also contains a USB port for
connection to your computer. The second part of R-DES is the
powerful and easy to load software for your Windows based computer. The photo
gives you an idea of how elegant and powerful this interface is.
How do I
use R-DES?
First you will measure the bass response in your room. You can do
this with a RadioShack SPL meter and the test tone CD and graphing
tools that come with R-DES. Or you can use measurement software like
TrueRTA,
EFT, etc,.* Once you see what you want to correct, you
will run the R-DES application on your PC and set up filters to
correct those problems. Let's say you have a 8dB peak at 70Hz, you
can setup a filter in R-DES that is a notch that is exactly the
opposite of your peak. This notch will then cancel out the peak
and you'll have a flat response! The four filters allow you to
very effectively smooth a subwoofer response.
What are the four coolest features of R-DES?
#1) It will make a major improvement in the sound quality of
virtually any system using a subwoofer #2) It is easy to use. #3)
It is extremely powerful; the hardware box can store four
different subwoofer curves. See the photo above for examples. In
addition, you can create an unlimited number of curves in your
computer and download any four different curves anytime you want!
#4) It is very affordable and will improve your
system far more than the cost would indicate.
What do I need to use R-DES?
You will need a PC running Windows 98 or newer and some method of
measuring the room response. (SPL meter,
TruRTA, EFT or the measurement package that we will have
available.)*
Other cool
features:
- Programmable subsonic
filter allows you to "protect" your sub without
cutting out any more bottom end than you have to.
- Programmable crossover
allows for additional installation flexiblity.
- Once the hardware box is
programmed you do not have to stay connected to the computer.
- Supplied with computer graph paper and a test CD to make
plotting your room response EASY! Just add an inexpensive
Radioshack SPL meter and you're ready to go!
- Future proof, software is
easily upgradeable!
What
about using R-DES with DIY subs?
R-DES is perfect for use with DIY subs. Think of the
possibilities; no need for separate crossover, subsonic filter, EQ,
etc. Ditch the low performing plate amp and use any good
amplifier with R-DES!
* We will soon be able to offer a test measurement package
that includes the software and a microphone to do your own
testing. This package is elegantly simply to use, yet powerful and
accurate. For example; it will allow you to average the
measurements from a number of sitting places in the room! And, it
will be very affordable.
