Rupert Neve Designs RNHP Precision Headphone Amplifier

You do a lot of production work in headphones, but your audio interface's headphone output doesn't sound so good. Solution: Rupert Neve's RNHP 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 high 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.


Get a closer look at the RNHP headphone amp in this video from Rupert Neve Designs:


Based on the headphone output circuit in the 5060 Centerpiece Desktop Mixer, the RNHP (Rupert Neve Headphone Amp) 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 read more 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
Professional Camera
Studio Monitor Controllers

Input B: RCA Devices
CD / DVD Players
Stereo Tuners
Preamplified Turntables
Prosumer Recording Devices / Cameras

Input C: 3.5mm (1/8") Stereo Devices
Mobile Phones
Portable Music Players
Computers
DSLR Cameras
Handheld Recording Devices
Any 3.5mm headphone output

VESA-Mountable Design

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.

Multiple-Line Feed

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.

Features:

Precision Sound: Wide-open, extremely detailed sound quality allows you to get the most out of your headphones

Dedicated Power: High-power, high-headroom design can effortlessly drive high-impedance (up to 600 Ohm) headphones even during the loudest, most dynamic tracking sessions

Reliable Translation: 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.

RCA Input: 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

3.5mm Input: Stereo 3.5mm input specifically calibrated to work with mobile devices like phones, computers and digital cameras

VESA Mount: 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).

Verified Customer zZounds has verified that this reviewer made a purchase from us.
I wanted a solid state headphone amp for critical mixing and production but also something fun to listen to while looking for entertainment. It certainly does both. Have tried a few different pairs of headphones with varying resistance and purpose and this amp powers them all with so much headroom they truly all had opened sound stages.Purchase this headphone amp if you want to have professional grade production headphone amp and a solid-state solution to entertainment listening.With the multiple inputs, I have it running from a Focusrite audio interface AND a Audioengine DAC. I can switch the Audioengine DAC to ASIO for critical listening and enjoyment of music and WASAPI/ASIO on the Focusrite I/O for general work/production.
