Audio Control AudioControl Richter Scale Series Three Equalizer Analyer Crossover

The Richter Scale Electronic Crossover (24dB / Octave) with Bass Equalization

Overview:

This unit was purchased a few months back for use in some potential speaker building projects. Plans have changed and there is no point in having such a nice piece of gear languishing on a shelf, unused. It worked just fine when I got it but need just a little TLC. I did a little bit of work and now it is working great and now the meter lights up quite nicely as well! It's worth noting that this is the only Richter Scale unit I have seen listed on Audiogon, eBay or anywhere else that included more than just the standard 90Hz crossover module. Your getting all of the original accessories plus 10, that's right, 10 modules. The values are captured in the photo gallery and listed below. Don't miss out on this rare opportunity!

Summary of work peformed:

Replaced expired bulb with four, new, high-brightness white LEDs.
Cleaned and lubed all serviceable controls -- the six sliders and the LF Output Level pot.
Removed the two worn out feet with four, new, felt padded feet.
Cleaned and treated all of the rear RCA jacks with CAIG ProGold Conditioning Treatment.

Here's the description from the manufacturer's website:

"The Richter Scale is a bass management system designed to have your subwoofer breaking new ground. A 24dB/octave, Linkwitz-Riley alignment will precisely match the crossover frequency of your subwoofer. A six band equalizer controls the critical bass region of 22.5 Hz to 125 Hz in one-half octave steps. A built-in lab-grade analyzer and warble tone generator enable precise measurement and calibration. The Subsonic filter prevents damage to your subwoofer by preventing inaudible tones from reaching the speaker. With The Richter Scale in your system, you'll hear more cleaner and tighter bass than ever before."
