It's suitable for use in pro audio scenarios, particularly in the studio.





This compressor takes the 2254's assets and helps eliminate its limitations by improving the noise floor, expanding the attack/release options, giving you a greater amount of threshold and ratio controls, and minimizing the effects of inter-modulation distortion. The unit uses a diode bridge as a gain control element to give you a pleasing, sonic character.





Controls are on hand for Threshold, Ratio, Timing, Gain, and Blend. These controls are detented for accurate recall. A Link switch lets you operate two of these compressors in stereo. Meters give you output-level readings or gain-reduction readings.





This unit is compatible with any compatible 500-Series chassis. It requires such a chassis to operate.The 551 Inductor EQ from Rupert Neve Designs is a three-band EQ with custom-wound inductors, transformers, and class-A gain blocks. The low-frequency 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 551's inductor midrange band is 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 12 dB/octave design with a fixed 80 Hz frequency, and can be used in tandem with the low-frequency EQ to add low-end presence without clouding the source material.





Both the high and low band can be switched from shelf to peak curves and offer 15 dB of boost or cut. The high band can be switched from 8 to 16 kHz, and the low band can be selected at 35, 60, 100, or 220 Hz. The inductor-based mid band offers six center frequencies: 200, 350, and 700 Hz, and 1.5, 3, and 6 kHz. The mid band also has an "MF Hi Q" switch to narrow the bandwidth (increase the Q) of the filter.The Portico 511 Mic Preamp from Rupert Neve Designs is a single channel, transformer-balanced microphone preamp that brings the features and performance of the full-sized Portico outboard rack units to the 500-series format. The 511 provides 66dB of gain, and a /- 6dB Trim knob is provided for fine tuning. Texture can be added by pushing the Silk button, which activates dedicated circuitry. The desired amount of texture can be dialed in with a knob, which adds harmonic content-creating tones that are reminiscent of vintage Neve equipment.





The 511 isn't limited to working with microphones. With the Gain knob set at 0 dB, the unit is capable of accepting line-level signals. Condenser microphones and active DI boxes can be powered by engaging the 48V phantom power button on the 511. An illuminated Polarity button inverts the signal when pressed. A variable High-Pass Filter can be engaged by an illuminated button as well, and a knob enables you to sweep between 20-250 Hz. An eight-segment LED meter allows you to visually monitor the output. A 500-Series power supply/rack is required for operation.With 150% of the required current for a 6-space 500-series enclosure, the Rupert Neve Designs R6 will help you hear the full potential of your modules. The headroom in available current helps prevent the power rails from falling under a higher than expected load. LED metering shows you how much power is being used and the internal power supply has been designed with double shielding to avoid significant magnetic induction in any of the channel positions.





The solid steel chassis has a collapsible handle for portability. The unit offers a total of eight balanced I/O channels with interchangeable TRS, XLR, and DB-25 connections with a 48V phantom power bus. The channel 7-8 thru connections can be used as a way to quickly and easily convert your signal from and to DB-25, XLR, and TRS connectors. To accommodate 500 series modules that are slightly out of spec, the unit has variable-position screw holes to make the installation process go more smoothly. A 500 series link function can be enabled in pairs using the link jumpers on channels 1-2, 3-4, or 5-6. Matching blank panels are also available to cover any empty slots.
