Monsalvat PRO-4

Signature Sound Processor

The Verity Audio’s PRO-4 Digital Processor is a unique device combining the functions of a preamplifier, a DAC, a digital crossover, and a time alignment device. The processor’s architecture features state-of-the-art ADC/DAC circuitry and total galvanic isolation between the analog and digital domains, ensuring they remain perfectly isolated. Filtering and delays are processed in the digital domain for absolute precision. The PRO-4 reaches the highest performance a “pure analog” preamplifier can attain while still offering the best you could expect of a reference digital signal processor.

Dots in a row

The PRO-4 features three sections: its processor chassis, its external power supply chassis, and a massive Verity anti-vibration platform. Both chassis are built of high-quality thick anodized and machined aluminum.

The PRO-4 truly is a state-of-the-art sound-processing device. It comes optional with our Lohengrin or Sarastro loudspeaker system or can be customized for other loudspeaker brands, offering an amazing sound performance that respects the natural scale of each instrument and preserves their respective coherence, fluidity, and musicality throughout their entire dynamic scale. In short, this new and unique processor unquestionably sets the new standard of superior performance in loudspeaker systems.

Some of our proudest achievements are our bolder innovations in design, such as rear-firing woofers and separate satellite and woofer cabinets. We believe our latest addition, which was inspired from the insulation platforms found between the various sections in many of our loudspeakers, will also prove its worth.
