CAUTION
RISK OF ELECTRIC SHOCK
'í
DO NOT OPEN
SAFETY PRECAUTIONS
PLEASE READ BEFORE INSTALLING
WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT
TO RAIN OR MOISTURE.
The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the
user of the presence of uninsulated “dangerous voltage” within the product's enclosure
that may be sufficient magnitude to constitute a risk of electric shock to you.
The exclamation point within an equilateral triangle is intended to alert the user of the
presence of important operating and maintenance (servicing) instructions in the
literature accompanying the unit.
Observance of polarity is essential. Double-check connections before turning
the amplifier on. The amplifier can be damaged if polarities are incorrect.
Damage can occur to your speakers if the power rating* of each individual driver
is exceeded by the amplifier. Ensure that all the drivers in your speaker system
are capable of handling not only the power being delivered by the amplifier, but
the energy that is likely to be generated during strong passages.
Turn amplifier ‘off when plugging in or unplugging input and speaker cables!!!
The TX4430 is equipped with raised feet so that continuous ventilation can be
maintained. They help to maintain acoustic feedback into the amplifier at a
minimum. They also provide a measure of protection against scratching any
surface the unit might be resting on. Do not alter or remove them.
Do not stack anything on top of the amplifier (preamplifier, processor,
source...etc.).
Leave at least 2-3 inches clearance from the top of the amplifier to the next shelf,
component, etc., to ensure proper ventilation.
If you are at all unsure of what the speaker ‘ratings’ are, contact your dealer.

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.
