Description

Model 535 Diode Compressor

The 535 Diode Bridge Compressor captures the soul of Rupert Neve’s original 2254 compressor with its punchy, thick versatile sound. Includes a host of modern updates that include 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.  Where the VCA compressor found in the 543 and Master Buss Processor provides unmatched clarity, the weighty, harmonically rich tonality of diode bridge compression can be essential in pushing key sources like vocals, electric guitars, bass and drums to the forefront of a mix.

FEATURES

Threshold

A 31-position detented pot that sets the level at which compression begins, from -25dB to 20dB. Turning this control counter-clockwise will increase the amount of compression; turning it clockwise will decrease the amount of compression.

Ratio

The RATIO control has 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 for levels above the determined THRESHOLD. This range of compression ratios allows the user to compress as moderately or heavily as desired.

Timing

The TIMING control is a six-position rotary switch that sets the compressor attack and release times. The timing can be further modified by the FAST button.

FAST

Fast Attack (750us), Fast Release (130ms) MF – Medium Attack (2.25ms), Fast Release (130ms) MED – Medium Attack (2.25ms), Medium Release (400ms) MS – Medium Attack (4ms), Slow Release (725ms) SLOW – Slow Attack (10ms), Slow Release (1S) AUTO – Medium Attack (5ms), Dual Decay Release (T1 500ms, T2 1s)

Fast The FAST switch 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

The BLEND control has 31 detents and allows the user to mix the uncompressed (dry) signal with compressed (wet) signal. Turning the control towards 0% will shift the mix to fully uncompressed dry signal, whereas turning the control towards 100% will shift the mix to the fully compressed signal. This feature allows for parallel compression, enabling a wider range of compression subtlety.

Gain

The GAIN control 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. It is much easier to evaluate the tonal effect of the compressor (via the COMP IN switch) when the compressed output level is matched to the uncompressed input level, thereby eliminating potentially misleading level differences.

Comp In

The COMP IN switch allows the user to audition the compression. By disengaging the COMP IN switch, the compressor is bypassed and the user can quickly compare the compressed sound to the dry input signal for an objective evaluation of the compressor’s sonic effect on the audio signal. COMP IN can be used in combination with the GAIN control to match the perceived level of the compressed audio signal with the level of the uncompressed input signal.

Link

The LINK switch allows the compressor to be linked to another 535 compressor module via a sidechain control voltage. In link mode, the compressor generating the greater sidechain voltage (resulting in higher amounts of compression) will control the compression of both audio signal paths to maintain proper stereo center image while compressing. Note: it is advisable to always audition the unlinked sound as well, to decide if the benefit of a constant stereo center image is worth the potential trade-off of reduced left / right independence in the stereo field.

Sidechain HPF

The S/C HPF switch allows the user to insert a 12dB/octave 150Hz high-pass filter in the compressor sidechain. When this filter is engaged, the compressor will be considerably less responsive to information below 150Hz. For example: if used on a drum kit, the low end of the kick drum would have less proportional effect on the compression than a snare drum or cymbals, since a significant portion of the kick drum’s dynamic energy is focused below 150Hz

Level and Gain Reduction Metering

These two LED meters provide accurate representations of both the output level of the compressor and the amount of gain reduction being applied to the input signal.
