Punchy, thick and versatile, the 535 Diode Bridge Compressor captures the soul of Rupert Neve's original 2254 compressor while providing modern updates including advanced timing control, significantly lower noise, fully stepped controls throughout, and internal parallel processing capabilities. Originally developed for the dynamics circuit of the acclaimed Shelford Channel, the 535 is outfitted with Rupert Neve Designs' custom transformers and class-A output amplifiers, all tailor-made for the popular 500-series format. 

Features:
• Threshold: A 31-position detented pot that sets the level at which compression begins, from -25dB to +20dB
• Ratio: six selectable positions on a rotary switch, allowing the user to set the slope of the compressor curve with pre-selected ratios of 1.5:1 through 8:1 
• Timing: six-position rotary switch that sets the compressor attack and release times
• Fast: divides the attack and release times available on the TIMING control in half, effectively doubling the number of TIMING presets available to the user
• Blend: has 31 detents and allows the user to mix the uncompressed (dry) signal with compressed (wet) signal
• Gain: has 31 detents and allows the user to add make-up gain to the compressed signal in order to bring its level back up to unity with the uncompressed input signal
• Comp In: allows the user to audition the compression
• Link: allows the compressor to be linked to another 535 compressor module via a sidechain control voltage
• Sidechain HPF: allows the user to insert a 12dB/octave 150Hz high-pass filter in the compressor sidechain
• Level and Gain Reduction Metering: provide accurate representations of both the output level of the compressor and the amount of gain reduction being applied to the input signal
