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
To drive your speaker diaphragms precisely, it is crucial that the positive and negative current paths in the voice coils be
precisely symmetrical. Duallogic-circuit technology aims to achieve that perfect balance by paying careful attention not only
to the type of circuitry used, but symmetry in structure and every other detail.
Damping: Vibration-Absorbing Technology
The chassis, carved from some 90 kg of aluminum, is matched to other materials and structure to produce the highest
degree of vibration suppression. The power transformer is also mounted in the chassis by four pin-point supports to suppress
internal vibration. In these and other ways, the design provides enhanced suppression of both internal and external vibration.
High 90 %+ efficiency
By using high-performance D-class amplifier circuitry with greater than 90 % efficiency, energy loss is reduced to a bare
minimum, producing a design with low power consumption.
High-capacity power unit
The TAD-M4300/TAD-M2500 design features two powerful 1 kVA power transformers, providing excellent responsiveness to
drive your speakers accurately.
Drive power with rated output 300 W / 4 Ω , 500 W / 4 Ω
Providing both low loss and high-speed performance, the lead-less power FET output stage features a simple single output
that producing effortless power of 300 W/4 Ω (4ch) in the TAD-M4300, and 500 W/4 Ω (2ch) in the TAD-M2500.
