Audison Thesis TH uno

Audison Thesis TH uno - 1-Channel Monoblock Amplifier with Class-A and Full-DA-HD

The Audison Thesis TH uno is a 1-channel amplifier that combines analog Class-A sound quality with digital signal processing. You get up to 2300 W into 1 Ω for powerful subwoofer setups and, if desired, pure Class-A operation with 200 W for focused music listening. The integrated 24-bit/192 kHz DAC and Audison Full-DA-HD support make the TH uno the perfect solution for high-res sources.

Installation & Compatibility

The TH uno excels as a powerful subwoofer driver or as a high-quality mono amplifier for demanding channels. It accepts analog preamplifier signals and digital input via S/PDIF/AD Link. With a minimum of 1 Ω load stability and a 150 A fuse concept, it fits into performance-oriented setups. The link functions allow multiple amplifiers to operate in a master/slave configuration – practical for large car audio systems at Carhifi.shop.
