Product description

• RME ADI-2 DAC High-Resolution USB DAC The RME ADI-2 DAC is a high-resolution USB DAC designed to deliver premium digital-to-analog conversion and clean headphone amplification for audiophiles, music lovers, and audio engineers in hi-fi setups and home, project, and commercial studios. It supports sample rates up to 768 kHz and is compatible with PCM and DSD sources. Enhanced circuit design yields excellent jitter suppression, expansive signal-to-noise ratios, and low noise.Route your audio players to the coaxial or optical digital inputs, or connect your computer or iOS device via USB. Stereo XLR and RCA line outputs offer a four-stage reference level selection and provide an easy connection to power amplifiers or active monitors. 1/4" and 1/8" headphone jacks accommodate a variety of headphones from traditional over-ear models to IEMs. The built-in DSP provides adjustable bass, treble, loudness, 5-band EQ, and more.Additional luxuries include a USB cable, power supply, remote control, and the integrated AutoDark feature, which automatically turns off all the ADI-2 DAC's lights after ten seconds without user operation.
  Flexible Sample Rate Support
  • Operates at up to 768 kHz via the internal clock or up to 200 kHz via external clocking. DSD and Direct DSD playback are also supported.
  Multiple Inputs
  • Hook up a CD player, digital mixer, or audio interface to the coaxial or optical digital input. Class Compliance allows you to connect your computer or iOS device via USB.
  Enhanced DAC
  • More relays, a different double-symmetrical attenuator circuit, and one additional buffer op-amp succeed in achieving less noise and decreased THD. Selectable hardware reference levels allow proper matching with your analog equipment.
  Low-Noise IEM Output
  • An 1/8" stereo mini-jack accommodates in-ear monitors. Its noise floor is 10 dB lower than the Extreme Power output, and the output impedance is nearly zero Ohms. SNR is 118 dBA while THD remains low. The volume ramp-up and click-free on/off features aid in protecting your hearing.
  Selectable AutoDark
  • All lights on the ADI-2 DAC turn off after ten seconds without user operation. Touch any button or control on the device to turn them back on for ten seconds. Or, using the remote, press any button on to turn on the lights for three seconds.
  User-Friendly Remote Control
  • The included remote control features clearly labeled buttons, readable in low light and ergonomically arranged. It boasts standby on/off, volume up/down, input selection, mute, and four programmable buttons, which can be assigned with 22 available functions and commands.
  SteadyClock FS
  • With SteadyClock FS, the focus was put on reducing the jitter of SteadyClock to new lows by improving its second analog PLL circuit and referencing both Direct Digital Synthesis and PLL to a low-phase-noise quartz crystal. The self jitter measured through DA conversion now reaches levels that usually are only available in master quartz clock mode, while SteadyClock still always runs in PLL mode. The sound remains the same regardless of internal or external clock mode. The low-phase-noise oscillator driving the updated circuit reaches jitter specs lower than a picosecond—an area called FemtoSecond, hence SteadyClock FS.
  Built-In DSP Processing
  • DSP processing includes controls for bass, treble, loudness, 5-band parametric EQ, crossfeed, width, M/S mode, polarity, oversampling filters, and more. DSP functions are bypassed when in DSD mode, which offers output to the USB and analog jacks.
• Rupert Neve Designs RNHP Precision Headphone Amplifier The RNHP Precision Headphone Amplifier from Rupert Neve Designs is a dedicated 24V reference-quality headphone amplifier that has a specifically-calibrated +4 dBu balanced line input, an unbalanced RCA input, and a 1/8" stereo mini-jack input, housed in a rugged VESA-mountable steel chassis. The headphone amplifier is based on the output circuit in the popular 5060 Centerpiece Desktop Mixer and has wide-open sonic performance with the ability to drive any pair of headphones up to 600 Ohms. The RNHP allows you to perform, mix, and enjoy your music with a new level of clarity. The 24V power supply is also included.
  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 Ohms) headphones even during the loudest, most dynamic tracking sessions
  Reliable Translation
  • The near-zero output impedance (.01 Ohm at 1 kHz), 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 +4 dBu 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 -10 dBV signals and is selected with the "B" switch. The RCA jack is commonly used with home stereo devices or prosumer equipment
  1/8" Input
  • Stereo 1/8" (3.5mm) input is specifically calibrated to work with mobile devices like smartphones, 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
  24 VDC Input
  • The RNHP can be powered using either the included 6W power supply or a 24V, 0.25A min battery (sold separately)
