B & K Components Ltd. SHALL NOT BE LIABLE FOR OPERATIONAL, TECHNICAL OR EDITORIAL ERRORS/OMISSIONS MADE IN THIS MANUAL. [. . . ] The Reference 200. 5 S2 or Reference 200. 7 S2 operates with a class A predriver and AB MOSFET power output stages. These high power amplifiers are capable of delivering full range while reproducing the most demanding music passages effortlessly into the most demanding audiophile speakers.
FEATURES
High Current - Ability to cleanly, accurately, and reliably reproduce demanding recordings or source materials into low impedance drivers and speaker systems. Class A Predriver - Improves low level detail and clarity for smoother, more musical sound. 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. These connectors accept balanced volume level outputs from the preamplifier's balanced output connectors.

RCA UNBALANCED
There are five unbalanced (RCA) input connectors on the Reference 200. 5 S2 and seven unbalanced (RCA) input connectors on the Reference 200. 7 S2. These connectors accept an unbalanced (RCA) output from the preamplifier's (RCA) volume level outputs.

SPEAKER CONNECTIONS
Binding posts are provided for speaker connections. There is one pair provided for each amplifier channel output. They are designed to accept a banana-type plug, spade-lug connector (shown right), terminal posts, or bare wire. They are color coded for easy identification. The positive (+) RED post should always be connected to the speakers (+) RED jack. The negative (-) BLACK post should always be Spade Connector connected to the speakers (-) BLACK jack.

SYSTEM INSTALLATION
There will most likely be a number of cables involved in the installation of your home entertainment system. [. . . ] For more information on the amplifier's output status under various control conditions, refer to the table below. *Note: The control input voltage is intended for standby on/off control only. For best amplifier operation, each amplifier is recommended to have its own source of AC power.
