Put a Shelford-Style EQ and Compressor in Your 500-Series Rack
Did you know that the equalization and compression circuits derived from our flagship Shelford Channel are available individually for the 500-Series format?
The 551 Inductor EQ
This 3-band, custom-tapped Inductor EQ was inspired by our favorite elements of Rupert’s vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response similar to a vintage 1064 – but unlike the vintage modules, the LF band on the Shelford Channel can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end.
The midrange band is inspired by that of the 1073, ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional “Q” response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage / modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control, with the shelf / peak corner switchable between 8K or 16K. Lastly, the High Pass filter is a 12dB/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material.
The 535 Diode Bridge Compressor
Like the Inductor EQ, the Diode Bridge Compressor is based on the same topologies found in Rupert’s vintage 2254 and 33609 designs – but refined & adapted for the modern engineer, with much lower noise and more flexible operation.
What is diode bridge compression? Where the VCA compressor found in the Master Buss Processor provides unmatched clarity, the harmonically rich tonality of diode bridge compression adds a “weight” to key sources like vocals, electric guitars, bass and drums, bringing them to the forefront of a mix.
Delivering the powerful sound of these iconic designs with enhanced versatility for the modern age, our Diode Bridge Compressor is a dynamic tool equipped to make a statement on virtually any mix or track.
