Mosconi Atomo 4|6 DSP – Compact 6-Channel Digital Signal Processor

Precision Audio Tuning in the Smallest Footprint

The Mosconi Atomo 4|6 DSP is a compact powerhouse built for vehicles with limited space but demanding sound expectations. It features four analog inputs (high/low level) and six analog outputs, with support for three digital inputs: SP-Dif, Bluetooth via MOS-BTS, and BT+ with direct DSP access.

Powered by a 64-bit platform, the Atomo 4|6 includes dynamic equalization and phase correction, ensuring sound is sculpted with total accuracy. Compatible with both 12V and 24V power systems, it's ready for use in cars, vans, or commercial setups.

Expandability is at your fingertips — upgrade to eight analog inputs using the MOS EXT4HLin module. Its Molex connectors and direct RTC support make integration and control simple, while the ultra-compact chassis (86 x 65 x 34 mm) allows installation where others can't fit.

Whether you're retrofitting an OEM system or building a high-end custom install, the Atomo 4|6 DSP offers unmatched clarity, power, and precision in a minimalist footprint.

If you're looking for superior processing power in a small form factor, the Mosconi Atomo 4|6 DSP is the ideal choice for your vehicle's audio upgrade.
