PURPOSE AND FUNCTION

PURPOSE AND FUNCTION

The Reference 200.5 S2 (Five channel) or Reference 200.7 S2 (Seven channel) is a high power amplifier that is designed for use in all types of audio or audio/video systems.

DESIGN AND CONSTRUCTION

The Reference 200.5 S2 or Reference 200.7 S2 amplifier utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized. The high quality parts complement includes: state-of-the-art solid state devices, 1% metal film resistors, computer grade elec- trolytic power supply capacitors, and a high capacity toroidal transformer. All B&K products are designed and hand assembled in Buffalo, NY U.S.A.

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 control- ling 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 fre- quency control, increased power supply, and improved dynamics.

Balanced Inputs - Balanced inputs deliver the quietest and most accurate signal path between the preampli- fier 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.
