WEIGHT 18 , Shipping: 26 Pounds POWER 120 VAC , 50 - 60 Hz , 22W Ma x Boulders proprietary 0.5 dB stepped volume control system performs with unmatched accuracy. This system produces the most sonically clear, yet reliable, method of attenuating the analog audio signal. The absence of distortion and noise from the mechanical sliding wiper used in a continuous potentiometer makes for a stunning improvement in clarity. Sonically, Boulders volume control has no equal. The 810 Stereo Preamplifier also features the Boulderlink system for complete system control and communication with other Boulder components. All necessary connections for external use and control are provided–an input for remotely located IR and a 12V trigger output for remote turn on of amplifiers. An illuminated alpha-numeric display allows you to name and program each input of the 810 Stereo Preamplifier. Each selection can also easily be read from across the room. Starting volume levels, gain matching, input balance, polarity, and Theater Mode can also be programmed for each individual input. Theater Mode allows the 810 to be integrated into a home theater system to seamlessly switch from audio to theater listening without compromising the performance of either. All of the 810 Preamplifiers machined metalwork is designed in Colorado and fabricated on Boulders own CNC machining centers. All electronics are engineered and produced in Boulder and tested at every step of production. Each piece of circuitry and metal is held to the strictest quality standards, assuring the greatest residual value for any investment in Boulder. The 810 derives performance and refinement from its predecessors in a way no other preamplifier possibly could. By using the expertise gained from the proven 2010 and 1010, Boulder has created yet another preamplifier without peer in its price class.
