DBX 242 Project 1 Parametric EQ - Designed by Bob Orban

Hard to find but sought after EQ that was designed by Bob Orban. Includes power supply!! $170.00 covers paypal and shipping to your door (US lower 48 states only).

The DBX 242 is a single channel 5 band equalizer that is exceptionally clean and quiet. The DBX 242 has a higher fidelity that can hit hard and stay cohesive; boosts bring out the subtleties of the audio rather than smearing them together. This EQ has ?? input and output connections for line level signals.

In Bob Orban?s own words:

?The design started out as the successor to the Orban 642. The improvement
was a complex crosscoupled feedback arrangement that allowed reciprocal
curves to +/-16dB EQ, yet still allowed an infinite notch. The whole
thing required a MAJOR optimization to solve all of the relevant
equations, because, unlike most EQ designs, the properties are not
guaranteed by the topology but rather by correct selection of (if I
recall correctly) six different resistors. (We have since received a patent on the topology, and, for the brave-hearted, the optimization procedure and the equations are to be found there.)

About that time, AKG decided to drop the Orban studio line and just
concentrate on broadcast because they had just purchased the remains of
the dbx Pro operation, and dbx was to become the new "pro" line.

The EQ design was pretty cool, but the powers that be at AKG decided that
we would sell a lot more of them if they were aimed towards the project
studio market. This required a few compromises, like a wallwart power
supply. But the main signal path is 5532s in low-gain inverting mode, and
it's actually pretty clean.?

Great for project studios, live sound, post production, or voice over work.
