Rupert Neve Designs RNHP Headphone Amplifier

The Rupert Neve Designs RNHP Precision Headphone Amplifier is a high-quality, dedicated headphone amplifier designed to provide exceptional audio performance for a wide range of headphones. Here’s an overview of its key features and benefits:

Reference-Quality Amplification:

The RNHP is engineered to deliver reference-grade amplification for any pair of headphones. It ensures that you hear your audio with exceptional clarity and fidelity.

Dedicated Design:

Unlike integrated headphone amplifiers found in many audio devices, the RNHP is purpose-built solely for amplifying headphones. This dedicated design allows it to deliver uncompromised power and audio quality.

Multiple Input Options:

The RNHP offers three input options – +4dBu balanced line, unbalanced RCA, and 3.5mm (1/8″) stereo inputs. These inputs are carefully calibrated to provide the optimum level and impedance for various audio sources.

VESA-Mountable Chassis:

The rugged steel chassis of the RNHP is VESA-mountable, making it versatile for various mounting options. It can be mounted on poles, walls, tables, or articulating arm mounts, ensuring that it’s always in the perfect position.

Multiple-Line Feed:

The RNHP accommodates scenarios where you need to feed both the headphone amplifier and another device simultaneously, such as speakers, a second headphone amplifier, or a 2-track recorder. It can be done using splitter cables from the Left and Right line outputs.

High-Power, High-Headroom Design:

The RNHP is capable of driving high-impedance headphones (up to 600 Ohms) with ease, even during loud and dynamic tracking sessions. It offers a high-headroom design that ensures optimal performance.

Low Output Impedance:

With a near-zero output impedance of 0.01 Ohms at 1kHz, the RNHP’s direct-coupled amplifier design minimizes frequency-based reactive-load impedance shifts, ensuring excellent audio translation with any pair of headphones.

Precise Level Control:

The stereo potentiometer is highly damped, providing precise level control and maintaining perfect left-right balance for accurate audio monitoring.

Calibrated Inputs:

The RNHP offers three input options, and they are all calibrated for specific signal levels and impedance, ensuring the best audio performance regardless of the source.

Power Options:

The RNHP can be powered using the included 6-watt power supply or a 24V, 0.25A min battery (not sold by RND), giving you flexibility in powering the unit.

Overall, the Rupert Neve Designs RNHP Precision Headphone Amplifier is designed to provide audiophiles, musicians, engineers, and listeners with a reliable and high-quality headphone amplification solution, allowing you to experience your audio with exceptional clarity and precision.
