RNHP Precision Headphone Amplifier
Headphone Amplifier
From Rupert Neve Designs:
Whether you’re tracking, mixing live or in the studio, 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.
Specs
- Maximum input levels
- “A” XLR I/P: +22.8 dBu @ 1 kHz; “B” RCA I/P: +14.7 dBu @ 1 kHz; “C” 3.5mm I/P: +3.3 dBu @ 1 kHz
- Output power
- As measured with typical headphones, Z=44 Ohm: 3.617 VAC RMS @ 1 kHz = 300mW RMS; 16 Ohm typical Load: 1.933 VAC RMS @ 1 kHz = 230mW RMS; 150 Ohm typical Load: 5.108 VAC RMS @ 1 kHz = 175mW RMS
- Output impedance
- .08 Ohm @ 1 kHz, 16-150 Ohm load, 0 dBu input
- Frequency response
- +/- .2 dB from 10 Hz to 120 kHz
- Noise (typical headphones, Z = 44 Ohm, BW 22 Hz - 22 kHz)
- “A” XLR Input: -101.9 dBV; “B” RCA Input: -100.9 dBV; “C” 3.5mm Input: -88.8 dBV
- Power supply requirements
- 24VDC @ 0.25Amp (6 watt) minimum; use with supplied power adapter; may be used with a properly configured 24V battery as well
