Two Channel Networked Amplifier

Model: Voltera D 4800.2M

Drive the most demanding loudspeakers — 4800W total output across two Class D channels provides exceptional headroom for large venues, high-output arrays, and long-throw systems.
Optimize audio exactly to specification — integrated DSP (equivalent to TesiraFORTÉ) delivers full loudspeaker management, routing, EQ, filters, delay, and system protection.
Integrate seamlessly into modern networked ecosystems — supports AVB, Dante, and AES67 for maximum compatibility with enterprise and performance audio networks.
Power nearly any loudspeaker topology — drives low-impedance loads (2.7, 4, 8, 16 ohm) as well as 70V and 100V constant-voltage systems.
Speed up commissioning with proven presets — ALAMOS loudspeaker profile library includes nearly 700 optimized loudspeaker tunings for consistent, repeatable results.

The Voltera D 4800.2M is a high-performance two-channel networked amplifier engineered for applications requiring maximum output power, pristine signal processing, and bulletproof reliability. Delivering 4800 watts of total output in a compact 1RU chassis, it is ideal for large performance venues, houses of worship, sports facilities, auditoriums, and any installation with demanding loudspeaker requirements. Equipped with powerful onboard DSP equivalent to a TesiraFORTÉ processor, the Voltera D 4800.2M eliminates the need for external signal processors. Its integrated toolset includes routing, EQ, filters, limiters, delay, and complete loudspeaker management—allowing fine-tuned system optimization directly within the amplifier. With the ALAMOS preset library, installers gain rapid access to nearly 700 loudspeaker profiles, ensuring predictable and consistent tuning across projects. Designed for demanding loudspeaker applications, the amplifier’s high peak-voltage output ensures efficient energy delivery even when driving systems that require elevated voltages, maintaining clean, low-distortion performance at all output levels. The amplifier seamlessly integrates into modern AV networks, supporting AVB, Dante, and AES67 for flexible interoperability. Its advanced limiter scheme ensures clarity and stability during high-demand audio playback, while PoE+ sustainment keeps the internal processor operational during AC power outages. Failover-to-analog input capability further enhances resilience by maintaining audio output if network transport becomes unavailable. With unmatched power density, intelligent system protection, and comprehensive DSP integration, the Voltera D 4800.2M offers a future-ready amplification platform built for the most critical commercial audio environments.
