We Want You Listening For A Lifetime
Used wisely, your new sound equipment will
provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often
undetectable until it is too late, this manufacturer
and the Electronic Industries Association’s
Consumer Electronics Group recommend you avoid
prolonged exposure to excessive noise. This list of
sound levels is included for your protection.
Selecting fine audio equipment such as the unit
you’ve just purchased is only the start of your
musical enjoyment. Now it’s time to consider how
you can maximize the fun and excitement your
equipment offers. This manufacturer and the
Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that
lets the sound come through loud and clear without
annoying blaring or distortion-and, most importantly,
without affecting your sensitive hearing.
Decibel
Level Example
30 Quiet library, soft whispers
40 Living room, refrigerator, bedroom away from traffic
50 Light traffic, normal conversation, quiet office
60 Air conditioner at 20 feet, sewing machine
70 Vacuum cleaner, hair dryer, noisy restaurant
80 Average city traffic, garbage disposals, alarm clock
at two feet.
Sound can be deceiving. Over time your hearing
“comfort level” adapts to higher volumes of sound.
So what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by
setting your equipment at a safe level BEFORE your
hearing adapts.
THE FOLLOWING NOISES CAN BE DANGEROUS
UNDER CONSTANT EXPOSURE
90 Subway, motorcycle, truck traffic, lawn mower
100 Garbage truck, chain saw, pneumatic drill
120 Rock band concert in front of speakers,
thunderclap
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it
comfortably and clearly, and without distortion.
140 Gunshot blast, jet plane
180 Rocket launching pad
Once you have established a comfortable sound
level:
• Set the dial and leave it there.

Taking a minute to do this now will help to prevent
hearing damage or loss in the future. After all, we
want you listening for a lifetime.

INTRODUCTION
Inspiring the joy of listening
Technical Audio Devices Laboratories, Inc. (TADL) grew from the spirit to discover technologies to perfectly recreate the pure
sound of live performances with uncompromising craftsmanship. We have inherited our philosophy from Bart Locanthi—
recognized across the globe as the ultimate sound technologist—who believed that genuine technology is true to the basics
and that genuine technology places greater importance on sound quality than on technology for its own sake.
At TADL, we are honing our technology to create equipment that reproduces musical sounds that evoke both the energy and
impact of live music.
Features
Symmetry: Duallogic-Circuit Technology
In order to drive the speaker diaphrams correctly, it is crucial that the positive and negative current paths in the voice coils
be precisely symmetrical. Toward the end of achieving this perfect balance, we have incorporated symmetrical design in the
current mode, electrical circuits, and speaker structure.
Damping technology: Vibration-Absorber Technology
Improvements in the quality of vibration damping have been achieved by using cast iron as a low-resonance material for
the chassis, adopting an adjustable point-support structure for the spikes and a 10 mm-thick aluminum vibration damper
between the transformer and chassis.
Low center of gravity: Lower Weight-Balanced Frame
The monocoque chassis is constructed from 35 kg of cast iron in order to produce a massive and stable foundation. In
addition, the TAD-M600 has adopted a wide-tread chassis structure by locating the legs on the outer edges of its body, further
lowering its relative center of gravity.
Drive power: 600 W/4 rated output
Ω
A balanced-amplifier connection has been used to combine a 5-parallel push-pull amplifier with multi-emitter transistors
producing brilliant high-frequency characteristics, so that the TAD-M600 can output 600 W/4 , 300 W/8 with ease.
Ω
Ω
High-capacity power source
A power transformer consisting of two El 133 x 85 transformers and a high-capacity filter condenser consisting of four
33 000 μF are used to create a high-power source strong enough to accurately drive the speakers even at high output levels.
Protection circuit
In the event of a short circuit in the speaker terminals, electrical overload, or abnormal heating due to a contingency, the
protection circuit is activated. When activated, this circuit shuts off the power to the amp in order to prevent further heating,
while informing the user through the color of the power indicator light. This protection circuit function assures your amplifier
and speakers of safety from damage resulting from such anomalies.
