Fibonacci Audio Manager 

Fibonacci is the name with which Leonardo Pisano became famous, an Italian mathematician who lived between the 12th and 13th century who contributed to the rebirth of sceince and elaborated a succession of numbers called the Fibonacci sequence, taking inspiration from the Golden ratio of Leonardo Da Vinci ( 1: 1.618). Even today, in the audio field, this report gets particular attention for the results it helps to obtain. I believe that no name can be more appropriate for this device which is able, through sophisticated data processing, to perceive music in all its characteristics.

Fibonacci Audio Manager is a device dedicated to the management of audio processes for active multi-amplification, made with all proprietary hardware and software components. The cards have golden tracks on all layers, very accurate mastering and the DAC with 32bit / 768Khz sampling makes it extremely quiet and therefore with high dynamic range.

It has balanced analogue and digital inputs (AES EBU) therefore usable with any type of source, and six balanced analogue outputs configurable through proprietary software.

It has an ultra linear power supply with dedicated transformers for each voltage made to our specifications.

The main feature of this device is that the signals are processed by 32-bit floating point processing, this means that the reconstruction of the audio sine wave is extremely precise and the dynamic range is very wide so as to give a perception of natural listening, rich in detail and with realistic transient reproduction.

The internal wiring is handmade using pure monocrystalline copper insulated in Teflon, ideal for not having losses in the transport of currents and signals.

The frame is built with 3 different materials, graphite, aluminum and stainless steel all damped with anti-vibration material, effective in controlling vibrations and consequently limiting artificial colors so that the sound is perceived neutral, precise and rich in natural harmonics.
