XSP-2 Differential Reference® Stereo Preamplifier

• A fully balanced, fully differential, purely analog, signal path - First and foremost the main signal path in the XSP-2, from its balanced XLR inputs, to its balanced XLR Main and Subwoofer outputs, is fully balanced and fully differential. That includes a fully balanced Volume control and fully balanced precision Bass Management High Pass and Low Pass Filters.

• Relay switching - All audio switching is done using fourth generation hermetically sealed subminiature relays to maintain absolute signal purity throughout the entire audio signal path.

• Premium audiophile quality active components used throughout – including Burr Brown OPA1678 op amps for line level signals, Burr Brown OPA1656 ultra low noise op amps and Burr Brown OPA1678 low distortion op amps in the phono preamp, and Burr Brown OPA1688 high current drivers for the headphone output.

• Audiophile quality ladder network Volume Control – The Rohm BD34701KS2 premium volume control chip provides precision, perfectly matched, fully balanced, and fully analog control for the analog signal paths inside the XSP-2, while offering the convenience and precision of digital control.

• Independent precision-tuned Bass Management filters – Each Low Pass and High Pass filter, for each channel, is implemented as a separate precision 12 dB/octave fixed frequency filter circuit. This ensures both precise frequency selection, and perfect matching between channels, and between low pass and high pass filters. (The configuration option simply chooses which filter is switched into the signal path.)

• Full stereo Bass Management – Fully independent Bass Management is provided for each channel. The two Subwoofer Outputs can be kept separate to offer true stereo Bass Management. Or, if you prefer, or only have one Sub, the Subwoofer Outputs can receive a summed mono Subwoofer signal.

• A full selection of analog inputs for all of your analog sources – including four pairs of unbalanced line level inputs, two pairs of balanced line level inputs, one pair of phono inputs, and one pair of unbalanced Processor Loop inputs.

• A Home Theater Bypass Input – which allows you to route the input from a separate balanced or unbalanced source directly to the output of the XSP-2 bypassing the circuitry and controls in the XSP-2.

• A Processor Loop – which can be used to insert an external processor, like a graphic equalizer, or a dedicated speaker equalizer box, into the signal path.

• Top quality parts and construction - Double sided FR4 circuit boards with plated through holes, SMD construction, and high quality parts throughout, ensure that your XSP-2 will continue to provide years of reliable service.

• Highly optimized circuit layout – ensures the best possible sound quality, with low distortion, wide bandwidth, and a virtually silent noise floor.

• Large blue OLED display and flexible menu system – The large blue high resolution OLED display is easy to read, gives you all the information you need, and can be fully dimmed for intimate listening. The flexible menu system offers easy access to all important features and makes menu navigation a breeze.

• Mute control – allows you to mute the audio output on your system, and then return precisely to your previous listening level, at the push of a knob or the click of a button.

Separate headphone output with intelligent headphone level control – A separate high current buffer amplifier delivers a high quality signal to drive your favorite headphones for personal listening. The intelligent level feature independently remembers the levels you set for your headphones and your main outputs.

• Full function remote control – lets you operate all of the controls without getting out of your favorite listening seat. Quick access buttons allow you to quickly select between your favorite analog or digital inputs.

• Heavy steel 3RU chassis with milled aluminum face plate - provides strength and rugged good looks.

• Universal AC line voltage operation - The XSP-2 has a high performance low noise switch mode power supply that can operate on anything from 100 VAC to 240 VAC.

• Full five year warranty - ensures that you’ll be able to enjoy your XSP-2 for years to come.

Compact full-function all metal infrared remote control (which uses two AAA batteries).

Note: The back of the XSP-2 remote control is held on by magnets. To replace the batteries gently pry the back off by inserting a small screwdriver carefully into the small notch at the lower end of the back plate. Replace the batteries with standard AAA batteries. (The minus terminal on each battery should be against the spring in the holder.)
