B&K TX4430 - Manual (Page 5)

The TX4430's purpose and function
The TX4430 is a compact, very efficient, three channel power amplifier. It is designed
to be used in all types of audio or audio/video systems.
Design and construction
The TX4430 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 TX4430 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. This product is certified to meet LucasFilm Home THX standards for power
amplifiers.
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.
