Product Description
AUDISON THESIS - TH quattro
INTERNAL
Dual Power
Power supply features four transformers with "dual power" function.
Auxiliary Power Supply
A separate, high-precision power supply is dedicated to the analog front-end and digital stages: max sound quality and noise immunity.
Bias Control
Hi-fidelity analog circuitry with user-selectable remote Bias control: ability to use the amplifier in full A class bias.
Removable Crossover Module
Maximum musical detail is retained with very sharp cut-off slopes.
ASC - Amplifier Status Controller
Continuously monitors the amplifier, allowing control through the built-in Status Display, remotely through the in-dash controller or with a PC.
AC Link Control Bus
A single daisy-chain connection links all amps to the in-dash controller or PC, allowing remote control and monitoring of the amplifiers.
Optical Digital Audio Inpu
All TH amplifiers can accept signal from an optical S/PDIF source. Volume can be adjusted through built-in control.
AD Link Digital Audio Bus
A new multichannel bus system sends the audio signal to all amps, with all the advantages of digital technology: easy connection without loss in quality.
Analog Inputs
ALNS, Line Noise Suppressor, analog inputs with pre-out feature, for noise free operation.
EXTERNAL
Top mount fuse
For visual check, the high current fuse is mounted on the top and can be quickly and easily replaced.
Status display
Directly connected to the ASC, provides local control, monitoring of the amplifier’s status as well as memory functions.
Heatsink
Extruded aluminium monoblock, worked with CNC (Computerized Numeric Control) machine and finished by anodic coating treatment.
