B a l a n c i n g A r t & S c i e n c e BP20/25 SERIES PREAMPLIFIERS Brystons BP20/25 series preamplifiers offer a significant step forward in capturing the subtleties, nuances and emotions of recorded music. Designed inside and out to reflect the improvements in the entire Bryston line, these preamplifiers are a perfect match to our new SST series of amplifiers. All aspects of the signal flow are greatly improved, with lower noise and distortion figures, and higher overload levels. FEATURES INCLUDE - Intermodulation distortion has been reduced to less than .0015% from 20 to 20kHz. - The noise floor has been significantly improved, reducing background hash to far below audibility. - Input to input crosstalk is essentially nonexistant to eliminate signal bleed-through from one source to another. - Components plug directly into glass-epoxy circuit boards, eliminating variations in signal travel and wire interaction. - Signal switching and audio connections utilize heavy gold plating to provide long-term trouble-free connections. - Gold plated balanced and unbalanced input and output connectors are standard. - A 12 volt AC/DC screw terminal connector on the rear of the power supply provides for a convenient remote start feature available on all Bryston amplifiers. All BP20/25 series preamplifiers are housed in steel cabinets for shielding to reduce electromagnetic interference effects. Buffered inputs provide for lower distortion and improved linearity from source components. A ground plane has been incorporated in this new design to further reduce crosstalk and noise throughout the internal circuitry. The power transformer is mounted externally to eliminate power-supply noise interference. Each and every BP20/25 series amplifier is assembled by hand and burned in for 100 hours to ensure performance for many years to come. It is backed by a 20 Year Warranty - unrivaled in the industry.

REMOTE CONTROL FEATURE The BP-25 version includes a remote control with motor driven volume up/ down, along with mute and absolute phase reversal buttons. Volume, mute and absolute phase can also be activated manually on the front of the preamplifiers if the need arises. MM/MC PHONO SECTION The huge librar y of music present on vinyl represents an irreplaceable treasure. As such it becomes more important than ever to reproduce the music with the greatest faithfulness to the original recording.
