It is built for commercial AV integrators who need high power and channel density in one networked device. As a rack-mount amplifier, the Voltera D 4800.4 drives low-impedance, 70V, or 100V loudspeakers and supports AVB, Dante, and AES67 for deployment on a converged AV network. It is designed for venues of any size, from restaurants to stadiums.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe Voltera D 4800.4 integrates amplification, loudspeaker processing, and networked audio so a single chassis replaces a stack of separate hardware. Its integrated DSP provides the essential capabilities needed for loudspeaker management, including group-controlled raised cosine EQ, FIR filtering, dynamic EQ, and comprehensive peak and thermal limiters that help avoid protective mutes and shutdowns. Each of the four channels drives 2.7, 4, 8, or 16 ohm loads as well as 70V and 100V constant-voltage lines, configured from the loudspeaker profile chosen during commissioning. Power sharing provides up to 75% of total power through any single channel, matching amplifier output to uneven loudspeaker loads. The amplifier is 100% software configurable by Biamp Tesira or VenueTune, and VenueTune offers a phased workflow with a graphical interface and support for importing floorplans. The ALAMOS loudspeaker profile library covers more than 200 Biamp models to speed commissioning. Because processing lives on each device rather than a central resource, system cost scales with power requirements. The unit can be sustained through PoE+ so the processor stays online without a reboot during a mains power loss, and it supports failover-to-analog operation.
