$915.00 $870.00

High precision headphone amplifier gives you the best output sound quality you need. RNHP empowers your headphone to sound the best so that you make better choices in microphone and placement, gives you a reliable translation of EQ and dynamics adjustments. Or, when listening to music, you will appreciate the full depth and detail of a recording.

Description

RNHP is designed to bring out the best in your headphone. Many cheap headphone amp on the market promise great audio quality, yet they compromise on power & performance. That leads to problems such as low headroom, unreliable performance, and a lack of focus. It has superb clarity, awesome punch and great dynamic.

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. 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.

For Musicians

Great monitoring experience enhance your performance 
Great performances come from a connection between musicians and instruments. One of the most critical roles of the RNHP is to encourage these great performances by providing the best possible monitoring experience, enhancing the connection to the instrument.

A little appreciated consequence of a non-ideal monitor path during tracking is the phenomenon of unconscious adaptation. When speaking or performing, the brain continually responds to cues from the environment without consciously being aware. Some examples of this phenomenon can be seen in how people speak louder with headphones on, or how slightly delayed auditory feedback can disrupt the speech pattern of even seasoned performers (Note to engineers: research and try out a speech jamming techniques if you ever want to be especially cruel to a performer). Although the effects of non-linear frequency response, high distortion, or low headroom in the monitor path can be subtle in comparison, the mechanism of unconscious adaption is essentially the same, and these auditory feedback anomalies disrupt the subtle emotional nuances that often separate sensational performances from all the others. As fellow music lovers and creators, the goal with the RNHP is to empower artists to perform with and react to these nuances by giving them the most unadulterated monitor path.

The integrated headphone amplifiers lack the sufficient means to perform well when driving the high-impedance studio headphones. For instance, you can’t use a BeyerDynamic DT770 on Focusrite Scarlett 2i2. You can hardly hear anything even with full volume.  With RNHP, you will not encounter such situations. It goes far beyond the necessary headroom and power required to ensure consistently ideal performance from all headphones – even with loud transient spikes.

The RNHP can be fed with either a traditional stereo cue feed derived from a mixing console / DAW or in tandem with any of the readily available headphone mixers on the market to significantly improve the feedback path to the musician.

For Engineers

Clarity and Translation You Can Trust
For modern engineers who frequently work in different spaces, use their “control” room for live tracking, or rely on a non-ideal room for mixing, headphones can be an undeniably important mixing solution. They can minimize acoustic anomalies, provide a reliable reference for critical listening choices, and function without the high SPL of loud monitors (often known to disrupt neighborly / marital bliss). In short, mixing with headphones is sometimes vital.

However, unlike static loads, the reactive load impedance that headphones present can vary greatly depending on frequency – far more so than loudspeakers. The result of this reactivity is that the frequency response, noise and distortion of many amplifiers will suffer when compared to the same amp with an ideal resistive load.

While using headphones for any form of critical listening – making decisions regarding mic placement, for example – these shifts from lesser amplifiers can provide a false account of the source material. The RNHP is designed with a near zero Ohm output impedance to minimize these issues in both individual headphones and when comparing multiple pairs of headphones. This performance is imperative for those who need to trust the decisions they make with headphones.

For Listeners:

Your Headphones Have Never Sounded Better
Whether you’re a professional engineer surrounded by expensive studio equipment or a music lover with just a laptop on your desk or your phone on the go, the RNHP can make a huge difference in the performance of your headphones. While many people have expensive headphones that they use with their Hifi system or mobile device, those headphones are incapable of reproducing all the dynamic range, detail, and spacial information within your music without the help of an exceptional amplifier. With the direct coupled, painstakingly crafted topologies, the RNHP will give you a level of performance you have never experienced with headphones before.

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.

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.
