Technologies
Pure digital signal transfer with a resolution up to 24 bit / 96 kHz
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).
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.
Provides the selection of four possible presets: Energy Saving, Hi-Current, Hi-AB Class and full A Class operation.
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.
Four Synchro-PWM power supplies allow for a very fast transient current response and to create a Dual Mono configuration.
