THESIS: BEYOND THE ABSOLUTE

TH due Amplifier | 1000 W total power | 2 x 500 W @ 2ohm | A-class

Thesis amplifiers are born with the know-how and experience achieved with the HV venti, improved by the innovation of digital technology. The result is a perfect combination between the highest level of analog technology and the advanced features of the digital technology in one unique product. The precious synergy with Full DA HD technology takes the in-car listening experience to a new level of excellence; the synthesis of a unique know-how employed in mobile audio reproduction.TH due is a bridgeable stereo amplifier: a logical choice and natural partner for systems where versatility, power and quality are the main parameters. The ultimate stereo amplifier.

Technologies

ECK DRC
FULL DA HD

Pure digital signal transfer with a resolution up to 24 bit / 96 kHz

ECK DRC
Hi-Res audio

According to the definition of HiRes audio provided by JAS (Japan Audio Society – jas-audio.or.jp), HV venti far exceed the above 40 kHz bandwith analog requirement, providing an astonishing 5 ÷ 75k Hz (@ -3 dB, 2 VRMS, 4 Ω).

ECK DRC
DIGITAL INPUTS AND OUTPUTS

Innovation is at the heart of the state-of-the-art digital decoding section. The S/PDIF optical input allows direct connection to digital sources with the ability to re-launch the digital signal to other Thesis amplifiers through the AD Link (Audison DigitalLink) system. Each amplifier features 192 kHz/24 bit PCM D/A conversion through a very high quality converter.

ECK DRC
BIAS CONTROL

Provides the selection of four possible presets: Energy Saving, Hi-Current, Hi-AB Class and full A Class operation.

ECK DRC
REMOVABLE CROSSOVER

Inherited from the HV venti and making the most of TH’s extreme versatility, the complete crossover circuit of the TH amplifier is removable; a high-end sound quality solution.

ECK DRC
DUAL MONO CONSTRUCTION

Four Synchro-PWM power supplies allow for a very fast transient current response and to create a Dual Mono configuration.
