[. . . ] AB MOSFET Output - Provides efficient and linear power delivery, as well as protection from thermal overload. Gold Plated Connectors - Improved sound with minimum signal loss and degradation. Five Way Binding Posts - High quality binding posts accommodate up to 4 gauge wire. Control Output - One 3. 5mm (1/8") 10-12 VDC @ 200 mA output for controlling other amplifiers or controlling external systems that use a voltage trigger. Control Input - One 3. 5mm (1/8") jack that allows standby on/off with a 5-24 VDC control signal. Toroidal Transformer - Efficient, high current, shielded transformer that supplies the amplifier with a clean and constant supply of power, even during highly demanding source material passages. Discrete Circuitry - Dynamically provides a full, accurate, and three dimensional reproduction of source material. 1% Metal Film Resistors - High quality resistors used in all active circuitry to reduce noise and obtain better sound purity. Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for extended low frequency control, increased power supply, and improved dynamics. Balanced Inputs - Balanced inputs deliver the quietest and most accurate signal path between the preamplifier and amplifier. Full Power Operation - Capability to operate at full power with a square wave input. Differential Input Stage - A current source load assures DC stability and wide bandwidth linearity. 5 Year Factory Warranty - All B&K products sold through an authorized dealers are covered by a 5 year parts and labor factory Warranty.
