The 5254 is two channels of iconic diode bridge compression, thoughtfully improved and refined for modern tracking, mixing, and mastering.
Since the early 1970s, Rupert Neve’s early diode bridge compressors have been revered for the punch & glue they bring to drums, instruments, and the mix buss – but these desirable characteristics were unfortunately accompanied by inflexible controls and fairly limited versatility. Rupert Neve Designs created the 5254 Dual Diode Bridge Compressor to capture the soul of these coveted compressors while providing modern updates including advanced timing control, significantly lower noise, fully stepped controls throughout, higher voltage power rails, and internal parallel processing capabilities.
Unlike our VCA compressors, which are built for exacting clarity, the harmonically rich tonality of the Dual Diode Bridge Compressor is built to produce a wide range of colors – and built to help you make a statement with your music. Based on the dynamics circuit originally developed for the acclaimed Shelford Channel, the 5254 is outfitted for dual mono or stereo use with Rupert Neve Designs’ custom transformers and class-A electronics, tailor made for a compact 1U 19” enclosure.
Fifty years after Mr. Rupert Neve created his first compressor designs, the Dual Diode Bridge Compressor reimagines the larger-than-life personality of these classic circuits with new levels of precision and control, enhanced creative power, and increased punch to your tracks, mixes, and masters.
The Diode Bridge
Where the VCA compressor found in the Portico II Channel 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. By understanding the limitations of the vintage units’ topologies, painstaking effort was taken to reproduce the unique tone of these classics while improving the noise floor, expanding inflexible time constants, adding full wave sidechain detection for improved dynamic response, and widening the range of threshold and ratio controls. Delivering the powerful sound of these iconic designs with enhanced flexibility for the modern age, the Dual Diode Bridge Compressor is a dynamic tool equipped to make a bold statement on virtually any mix or track.
Timing is Everything
The unified TIMING control consists of six selectable settings, carefully chosen for different applications – a major departure from the slow, fixed attack of the vintage units. FAST and MF settings are designed to help clamp down on more transient signals like drums, plucked string instruments and fast vocals. MED and MS have slightly slower attacks and releases which allow more transients through, while having a slightly longer recovery. Lastly, SLOW and AUTO are both significantly slower and feature complex nonlinear release times, with smoother, less audible level control.
FAST mode increases the speed of both the attack and release for each setting, also effectively doubling the number of time constants from 6 to 12. The FAST mode also allows for a dramatic increase in speed as compared to the Dual Diode Bridge Compressor’s renowned ancestors, providing significantly more tonal & operational versatility.
Rupert Neve Designs RHNP Headphone Amp
With effortless, wide-open sonic performance and the ability to drive any pair of headphones without compromise, the RNHP allows you to perform, mix and enjoy your music with a new level of clarity. Whether you’re tracking, mixing, or just listening to music, your headphone amplifier is as important to the final sound quality as your headphones so Rupert and his team at Rupert Neve Designs have developed the RNHP.
Rupert Neve Designs RNHP Precision Headphone Amp Features
Wide-open, extremely detailed sound quality allows you to get the most out of your headphones
High-power, high-headroom design can effortlessly drive high-impedance (up to 600 Ohm) headphones even during the loudest, most dynamic tracking sessions
The near-zero output impedance (.01 Ohm at 1kHz), direct-coupled amplifier design provides for excellent translation with any pair of headphones
Precision Stereo Potentiometer
The highly damped stereo potentiometer is designed to give you precise level control and maintain perfect left-right balance
Professional Line Input
The calibrated +4dBu line input is selected with the “A” switch. The combo jack accepts either XLR or TRS inputs for balanced professional devices.
The unbalanced RCA input is calibrated for -10dBV signals and is selected with the “B” switch. The RCA jack is commonly used with home stereo devices or Prosumer equipment
Stereo 3.5mm input specifically calibrated to work with mobile devices like phones, computers and digital cameras
The VESA 100 compatible mount enables you to mount the RNHP wherever it needs to be. Common mounts are pole-mount arm for mic stands, pivoting multi-arm desk mount, and wall / surface mount for securing upside-down under a table, music stand or other studio furniture
Steel Clamshell Chassis
The RNHP’s rugged, solid-steel chassis is built to a high industrial standard with an overhang to protect the connectors and main level control from glancing blows, as well as shock-absorbing rubberized feet
24V DC Input
The RNHP can be powered using either the included 6 watt power supply or a 24V, 0.25A min battery (not sold by RND)
Based on the headphone output circuit in the 5060 Centerpiece Desktop Mixer, the RNHP is a dedicated 24V reference-quality headphone amplifier with specifically-calibrated +4dBu balanced line, unbalanced RCA and 3.5mm (1/8”) inputs, housed in a rugged VESA-mountable steel chassis.
Dedicated vs Integrated Amplifiers
For much equipment, the headphone output is an afterthought. Most products with integrated headphone amps have large feature sets, small footprints, and relatively low price points. This leads to comprised power and audio quality of the headphone amplifier itself, which can lead to a number of issues in real world usage such as low headroom, unreliable performance, and a lack of focus.
The RNHP was made to accomplish one simple purpose: making any headphones sound their best. As a dedicated design, the RNHP is tailored to deliver extremely high quality, powerful amplification, with precise calibration for any source input. This exceptional level of quality can be the difference that inspires an artist to give their best performance, lets an engineer make better choices in mic and placement, gives a mix engineer reliable translation of EQ and dynamics adjustments, or lets a music listener appreciate the full depth and detail of a recording.
Specially-Calibrated Inputs For All of Your Devices
In addition to being able to drive a wide variety of headphones without sacrificing performance, the RNHP is also capable of receiving a wide array of signals with its 3 inputs, calibrated for optimum level and impedance. Check the Application notes for how the RNHP can be utilized for different purposes.
Here are some common device examples:
Input A: +4dBu Line (XLR or TRS) Devices
Studio Audio Interfaces (Line or Monitor Out)
Headphone Mixers (Line Output or HP Out)
Mixing Consoles (Line, Aux or Monitor Out)
Professional Turntable Mixers (Line or Monitor)
Professional Stereo Digital to Analogue Converter
Studio Monitor Controllers
Input B: RCA Devices
CD / DVD Players
Prosumer Recording Devices / Cameras
Input C: 3.5mm (1/8") Stereo Devices
Portable Music Players
Handheld Recording Devices
Any 3.5mm headphone output
The RNHP is designed for mounting with any VESA 100 compatible mount. These may include pole mounts, wall mounts, table mounts, or articulating arm mounts. These mounts can help to ensure the RNHP is always in the perfect position.
In some situations where you only have one set of outputs but need to simultaneously feed the RNHP and another device such as speakers, a second headphone amplifier, or a 2-track recorder, we recommend using splitter cables from the Left and Right line outputs to feed both devices from the same stereo pair.
