Biamp 920-01992-00001 Voltera D 4800.4M

Product Overview

The Biamp Voltera D 4800.4M is a four-channel networked amplified loudspeaker controller that pairs 4800 W of Class D amplification with a fully programmable onboard DSP in a single rack unit. It is built for commercial AV integrators who need high power density, loudspeaker processing, and networked audio from one device. As a rack-mount DSP amplifier, the Voltera D 4800.4M drives low-impedance, 70V, or 100V loudspeakers and supports AVB, Dante, and AES67 for flexible deployment on a converged AV network. Onboard processing lets it replace an external DSP in many commercial audio designs.

Product Description

The Voltera D 4800.4M integrates amplification, loudspeaker management, and networked audio so one chassis handles work that once required separate amplifier and DSP hardware. Its onboard DSP offers headroom equivalent to a TesiraFORTÉ, giving system designers room for complex signal processing and audio distribution. Each of the four channels drives 2.7, 4, 8, or 16 ohm loads as well as 70V and 100V constant-voltage lines, with the correct settings applied from the loudspeaker profile chosen during commissioning. Power sharing allows up to 100% of total power to be delivered through any single channel, which matches real-world layouts where channels carry uneven loads. The amplifier is 100% software configurable through Biamp Tesira or VenueTune, and the ALAMOS loudspeaker profile library covers more than 200 Biamp models to speed setup. Because processing is distributed on each device rather than drawn from a central resource, system cost scales with power requirements as projects grow. The unit can be sustained through PoE+ so the processor stays online without a reboot if mains power drops, and it supports failover-to-analog operation. Integrators can compare companion models such as the Voltera D 4800.2M and the standard-DSP Voltera D 4800.4, or view the full Biamp collection.

Key Features

• 4800 W Across Four Channels — The amplifier delivers 4800 W total with all channels driven, supplying 1200 W per channel for demanding commercial loudspeaker systems.
• Onboard Programmable DSP — A fully programmable DSP with headroom equivalent to a TesiraFORTÉ handles loudspeaker processing and distribution without a separate processor.
• Networked Audio Support — Each unit supports AVB, Dante, and AES67 over two 1000Base-T ports in converged, split, or redundant network modes.
• Power Sharing — Power sharing delivers up to 100% of total power through any single channel to match amplifier output to uneven loudspeaker loads.
• Flexible Output Drive — Every channel drives 2.7, 4, 8, and 16 ohm low-impedance loads as well as 70V and 100V constant-voltage lines.
• PoE+ Processor Sustain — When port 1 is connected to a PoE+ switch on a UPS, the processor stays online through a mains power loss without rebooting.
• ALAMOS Profile Library — Nearly 700 loudspeaker profiles covering more than 200 Biamp models speed commissioning in Tesira or VenueTune.
• Single Rack Unit — The 1 RU chassis provides high power and channel density where rack space is limited.

Typical Applications

Frequently Asked Questions

Does the Voltera D 4800.4M require a separate DSP?
No. It includes a fully programmable onboard DSP with headroom equivalent to a TesiraFORTÉ, so in many designs it replaces an external processor for loudspeaker management and distribution.

Which loudspeakers can it drive?
Each channel drives 2.7, 4, 8, and 16 ohm low-impedance loads as well as 70V and 100V constant-voltage lines, configured through the loudspeaker profile selected during setup.

What audio networks does it support?
It supports AVB, Dante, and AES67 over two 1000Base-T ports and can run in converged, split, or redundant network modes.

How is it configured for AV system integration?
The amplifier is 100% software configurable using Biamp Tesira or VenueTune, with the ALAMOS profile library available to speed commissioning.

Will it stay online during a power outage?
If port 1 is connected to a PoE+ switch backed by a UPS, the processor is sustained through a mains power loss without rebooting, and the unit supports failover-to-analog operation.

How much rack space does it need?
The chassis occupies a single rack unit (1 RU) and ships with a rear support kit for 19-inch rack mounting.

What warranty and compliance does it carry?
The Voltera D M series carries a 5-year warranty and is compliant with the US Trade Agreement Act (TAA).
