B&K ST2020 - Design and Construction; Features

The ST2020's purpose and function
The ST2020 is a compact, very efficient, two channel power amplifier. It is designed to
be used in all types of audio or audio/video systems.
Design and construction
The ST2020 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 include state-of-the-art solid state devices, 1% metal film resistors,
computer grade electrolytic power supply capacitors, and a high capacity toroidal
transformer.
The ST2020 operates class A predriver and AB high current MOSFET power output
stages. It is capable of reproducing the most demanding audio signals at rated power
levels.
Features
Toroidal Transformers - Efficient high current transformer for improved dynamics.
Discrete Circuitry - More accurate and three dimensional reproduction of source
material.
Class A Predriver - Improves low level detail for smoother, more musical sound.
AB MOSFET Output Stage - For efficient and linear power delivery.
Limited Protection - Provides short term protection from accidental shorting of output
devices and protection from thermal overload.
Gold Plated Connectors - Improve connections for better sound and minimized signal
loss and degradation.
1% Metal Film Resistors - Low noise resistors for better sound and a greater degree
of repeatability.
High Current - Ability to reproduce demanding recordings.
Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors
for extended low frequency control and improved dynamics.
