| Content | In addition to the 100% analog tape emulation circuitry – great for bringing out 3rd-order harmonics – the 542 incorporates a soft-clip circuit that tames the harshest sources and enhances 2nd-order harmonics, variable Silk Red & Blue for an infinite variety of transformer tones, and a blend control to dial in in the perfect amount of saturation.
Transformers Imitating Tape
Unlike digital emulations, the “True Tape” drive circuit works by feeding a custom-designed interstage transformer acting as a “record head”, which in turn is coupled to a correctly-equalized replay amplifier. As the voltage rises on the “record head”, saturation increases, and a soft clip circuit engages at higher levels to round off peak transients. The sound of the tape circuit can be further modified with selectable 15 / 30 IPS modes and a pre/post-tape blend control.
What is Silk?
In addition to the tape circuit, the continuously variable Texture control with Silk Red and Silk Blue modes provides a whole other level of control over the harmonic density and tonality of your tracks & mixes. The Silk Red mode accentuates transformer saturation in the high and high-mid frequencies to amplify the vibrant midrange harmonics associated with Rupert’s vintage equipment, while Silk Blue accentuates saturation of the lows and low-mids to add thickness and weight to any source – especially useful for “thin-sounding” tracks or mixes. Unlike EQ, these Silk & Texture controls saturate the output transformers, and add highly musical harmonics to the source material according to the amount of Texture applied.
Drive the 542 hard, choose your Silk flavor, and crank the Texture knob for a rich, saturated, vintage vibe – or disengage Silk entirely for a more purist, hi-fi tape effect. The choice is yours.

POWER REQUIREMENTS
Supplied by 500 series rack with 110-125 mA @ +/- 16V DC | The vintage EQ tones you know & love.
The 551 is the only equalizer for the 500 Series actually designed by Rupert Neve. Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format.
The “Best-Of” EQ
The 551’s 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 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end.
The midrange band is based on 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. 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.
As with Rupert’s most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 50 years ago, and is definitely not a “clone”.
What Are Inductors?
Inductors are wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is what makes them different from capacitor-based EQ designs, which do a great job at surgical equalization. But inductors provide the tone.
While it is certainly possible to create a functioning EQ using off-the-shelf inductors, we choose to use our own custom inductors for the 551. This attention to detail in controlling variables such as the winding and core materials in relation to the surrounding circuitry allows the 551 to capture the vitality and personality of Rupert’s classic designs.

| Proven reverberation classic for the future
With the VSR 3.2, we happily rely on the proven old mechanical way to create reverberation. Rightly, because the used reverberation spring by AccuBell (formerly Accutronics) creates that magic 60's reverb which is slightly metallic and dense at the same time.
Just like it predecessors, VSR 3.2 has a straight-forward and honest approach: signal in - spring reverb - vintage sound out.
VSR 3.2 is equipped with an equalizer that is exactly adapted to the springs' frequency response. In addition, there are controls to mix the dry and effect signal as well as controls for the input and output level. This way, VSR 3.2 simply exactly does what it was designed to do.
Designed for every situation
Although using a large spring (type 9), VSR 3.2 fits in a 19" housing with one rack unit – minimal space requirements. Thanks to its extremely solid chassis, VSR 3.2 is a reliable vintage-effect that cannot only be used in a controlled studio environment. On the contrary, it also serves fine when being used in straining live situations.
VSR 3.2 grants your sound an elegant touch of "good old times". Its simplicity makes it an unbelievable versatile companion.
