Four Channel Networked Amplifier
Model: Voltera D 4800.4
- Power larger multi-zone or multi-driver systems — 4800W total output across four Class D channels delivers ample headroom and consistent performance for complex loudspeaker deployments.
- Achieve precise loudspeaker tuning — integrated DSP provides comprehensive loudspeaker management, including EQ, filters, delay, and protection settings.
- Integrate seamlessly into modern AV networks — supports AVB, Dante, and AES67 for flexible interoperability across enterprise and performance audio environments.
- Drive virtually any loudspeaker load — supports low-impedance (2.7, 4, 8, 16 ohm) and constant-voltage (70V/100V) systems for maximum deployment flexibility.
- Accelerate commissioning — ALAMOS loudspeaker profile library offers nearly 700 optimized loudspeaker presets for fast, consistent installation.
The Voltera D 4800.4 is a high-efficiency four-channel networked amplifier engineered to deliver powerful, reliable amplification with integrated digital signal processing. With 4800 watts of total power in a compact 1RU chassis, it offers exceptional performance for demanding commercial environments such as performing arts centers, houses of worship, stadiums, corporate auditoriums, and large hospitality venues.
Featuring integrated loudspeaker management DSP, the Voltera D 4800.4 streamlines system design by eliminating the need for external processors. Installers gain full control over routing, equalization, filtering, delay, and protection settings directly within the amplifier. The extensive ALAMOS loudspeaker profile library enables fast, accurate tuning across a wide range of loudspeaker models.
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.
With full support for AVB, Dante, and AES67, the amplifier integrates easily into diverse audio networks, providing exceptional flexibility for both new installations and system upgrades. Its advanced limiter scheme prevents audio dropouts during high-demand peaks, ensuring smooth and uninterrupted performance.
PoE+ sustainment keeps the internal processor powered during outages, while failover-to-analog input capability guarantees continuous audio delivery even if network transport fails. Combined, these features make the Voltera D 4800.4 a resilient, high-performance solution built to support mission-critical audio systems.
