Wadia A340 Mono Amplifier
The Wadia a340 digital mono amplifier provides 400 watts at 8 ohms or 500 watts at 4 ohms into a single channel. It shares the same sleek, modern industrial design as the 321 decoding computer, making a pair of a340s a perfect choice to use with the 321 to build your audio system.

Due to their electronic switching design, Wadia's new generation of amplifiers - including the a340 - are able to deliver massive amounts of power directly to your speakers with very little energy wasted in heat generation and dissipation. The large cooling fins or noisy fans often found in other high power amplifiers are no longer necessary. The result is a greener, compact and energy efficient amplifier.

The a340 includes the latest technology from Wadia. It features a comprehensive balanced signal design from input through output stage known as IO Symmetry™ that provides total system differential pairing - resulting in increased audio quality and noise reduction. Frequency Switching Transmission™ (FST) is an adaptive modulation design in the amplifier circuitry that assures full output power is delivered over the entire audio spectrum. To protect your speakers, Signal Surveyor™ monitors the output signal and stops amplification if unsafe levels of DC voltage are detected.

Both balanced and unbalanced inputs are available for connecting your other system components; balanced and unbalanced outputs are also included for ease of connecting bi-amp configurations. Specially designed 5-way binding posts will securely hold your speaker wire; they are designed for easy finger tightening and come with a special tool if even more snug connections are desired. A trigger input and output makes it simple to control the power state of your entire system when the a340 is turned on/off.
