Audison Thesis TH quattro

Audison Thesis TH quattro - 4-Channel Amplifier with Class-A Mode and Digital Inputs

The Audison Thesis TH quattro is a 4-channel amplifier that combines analog topology with modern digital technology. With up to 4 x 260 W at 2 Ω, switchable Class-A operation, and an integrated 24-bit/192 kHz DAC, a powerful yet precisely controllable system can be built. An internal microprocessor handles the precise management of gain, filters, and operating profiles – ideal for high-quality front/rear setups, active multi-way systems, or powerful sub/front combinations.

Installation & Compatibility

The TH quattro excels in SQ-oriented active setups as well as in powerful front/sub configurations. Thanks to digital inputs, you can connect a DSP directly via S/PDIF or AD Link. There is no high-level input; use preamplifier outputs or the digital interfaces. For maximum sound quality, the Class-A mode (55 W x 4) is available, and for high levels, powerful operation at low impedances down to 1 Ω per channel. The 100‑A fusing and the stable 11–15‑V vehicle electrical system ensure the supply of large systems.
