Bryston has just began shipping its highly anticipated SP-3 processor/preamplifier ($9500 US) to authorized Bryston dealers worldwide. The SP-3 will provide 2-channel stereo output as well as 5.1, 6.1 and 7.1 surround output modes and decoding is provided for all the latest formats including Dolby TrueHD and DTS-HD Master Audio.

The Bryston SP-3 is first and foremost an ultra high performance audio product. Unlike most surround processors that have been designed to emphasize features over sonic performance, Bryston employs Class A discrete analog circuitry throughout rather than cost-saving Integrated Circuits (IC’s). And like other Bryston components, the SP-3 utilizes separate and carefully isolated power supplies for the analog and digital circuit paths (achieves lower noise floor) plus modular construction to facilitate future upgrades. While most theater processors provide an analog pass-through option that moves the audio signal through undesirable digital circuitry before it exits the device, the Bryston SP-3 provides true analog pass-through for 2-channel as well as 5.1 and 7.1 surround formats that eliminates all digital circuits from the signal path. When switching sources on the SP-3, audio and video signals switch together, eliminating the need for external video switching devices.

The Bryston SP-3 is the first high performance processor designed to make home theater easy for the non-technical user. For example, most functions are automatic, controls are well labeled, and there are clear unambiguous display windows. Step-by-step set-up menus are provided and a user-friendly yet comprehensive owner’s manual make initial set-up simple and straightforward. Bryston also supplies each SP-3 with factory settings that include the most common configurations dialed in and ready for playback. Firmware updates and global system diagnostics are handled via the home network, making service a breeze for both dealers and end users.

Bryston SP-3 Key Features:

  • Audiophile sound quality and construction—all analog gain blocks are fully discrete; premium components and hand-matched transistors used throughout; two separate independent linear power supplies with toroidal transformers isolate analog and digital circuitry preventing crosstalk or interference
  • Easy to use — automatically detects input signal bitstream type and adjusts mode. VFD window shows decoding and signal information and error messages; LED?indicators show button selections. Clean, uncluttered control layout
  • Flexible input management—select from 11 sources, including 6 digital and 1 with discrete analog two- channel stereo and 7.1 analog inputs. Toggle button switches easily between digital and analog inputs
  • Audio and video inputs switched concurrently
  • 7.1 Balanced (XLR) outputs
  • 7.1 Single Ended (RCA) outputs
  • Stereo down-mixing options for all surround modes
  • Digital bass-management modes for all speaker setups
  • Bass redirection modes for any speaker set-up
  • Dolby Volume—optional dynamic range limiting for late-night operation
  • Music DSP surround modes for two channel inputs
  • Easy set-up — VFD window provides built-in menus for speaker set up, trim and delay adjustments etc.
  • Built-in pink noise test-signal generator and test sequencer makes calibration simple
  • Individually adjustable trims and delays for each channel
  • Each input can have preferred mode saved to memory
