Give your headphones the power and clarity they deserve.
Whether you’re tracking, mixing, or just listening to music, your headphone amplifier is as important to the final sound quality as your headphones – yet the world is full of headphone amps with compromised sonics, headroom, and power. To address these shortcomings, Rupert and his team at Rupert Neve Designs developed the RNHP.
Based on the headphone output circuit in the 5060 Centerpiece Desktop Mixer, the RNHP is a dedicated 24V reference-quality headphone amplifier with +4dBu balanced line, unbalanced RCA and 3.5mm (1/8”) inputs – each specifically calibrated for optimum level and impedance – and housed in a rugged, VESA-mountable steel chassis.
