Audison TH quattro

Amplifier | 1040 W total power | 4 x 260 W @ 2 ohms | Class A
The Thesis amplifiers are created with the expertise and experience gained through the HV Venti, further developed with the innovation of digital technology. The result is a perfect combination of the highest level of analogue technology and the advanced features of digital technology in one and the same unique product. The valuable 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 in mobile audio reproduction. TH Quattro is a four-channel amplifier, fully adjustable and completely manageable via the internal microprocessor, for unlimited system configurations.
