The MAX mono-blocks showcase Audionet’s latest ULA (Ultra-Linear-Amplifier) technology, recognized internationally for its innovative circuitry. Originally developed for medical engineering, this intricate topology pushes the boundaries of current measuring techniques. Under challenging conditions, the MAX ensures nearly undetectable signal impurity, thanks to outstanding feedback damping, allowing loudspeakers to perform crisply at their capacity limits.
The MAX's efficiency and precision reveal even the subtle sound properties of components and materials. Each sound-critical point is exclusively fitted with globally sourced, high-quality components, often custom-made for Audionet. The High Audiograde electrolytic capacitors, featuring a silk dielectric, originate from Japan, while low-loss capacitors are crafted from mica, a silicate sourced from India and China.
In the manufacturing process, every mono-block undergoes meticulous checks, precise measurements, and optimal pairing of components to ensure top-notch performance. Selection includes high-current foil capacitors with minimal loss, silver-gold alloys for internal wiring, and premium connector systems from Furutech. The MAX’s fuses are even composed of rhodium and gold, adding to the overall quality of the product.

To ensure optimal channel separation, the MAX is meticulously designed as a mono amplifier. The assembly of the mono-blocks is magnetically and capacitatively optimized, effectively minimizing feedback from electrical interference and reciprocal influences between amplification channels. The robust aluminum cabinet eliminates undesirable subsonic noise effects.
To enhance high-frequency attributes and velocity, minimalization is prioritized. Signal paths are kept simple and free from sound-impairing components like coils, chokes, or power relays.
The MAX features RCA and XLR inputs, electronically switched via gold-plated precision relays. The input stage, configured as a cascaded and bootstrapped differential amplifier with a low-noise, monolithic dual FET, ensures electrical decoupling of end amplifiers from the input signal, preventing harmful interaction with the source. A double cascade separates the source signal from the driving and output stage, while a unique, cross-linked correction circuit locally linearizes distortion in real time. The input and driving stage each receive power from an oversized 80 VA toroid-core transformer with separate windings for positive and negative operating voltage.
The output stage boasts eight hand-selected power MOSFETs with actively controlled bias current (0.6 A). Rapidly stabilized supply voltage is ensured by optimized discrete MOSFET regulators. For optimal performance, the negative and positive operating voltage are completely decoupled. Two 1000-VA toroid-core transformers feed the positive and negative half-cycles of the mains, supported by four high-current capacitors totaling 156,000 uF for efficient filtering.
A microprocessor unit oversees functions and monitors DC, HF, temperature, and overload. In case of a fault, it disconnects the MAX from the mains. A large, two-line display provides plain text indications of fault sources. The Audionet-Link enables optical remote activation and signal-dependence in three sensitivity ranges. The control unit is powered by a separate transformer.
