Voltera amplifiers and amplified loudspeaker controllers are packed with sophisticated yet simple one-of-a-kind features that drive system reliability and audio performance, as well as space and cost savings.
Voltera Product Information

The Voltera A Series comprises four half-rack amplifiers with a total power of 300 or 600 watts, delivered by two or four channels in a sleek, compact design. The amplifier channels are extremely flexible in that they can individually be selected to drive either 4 ohm, 8 ohm, 70 V or 100 V, while also supporting power sharing so that up to twice the power can be delivered by any channel. The Voltera A Series is ideal for restaurants, hotels, bars, education, small houses of worship, corporate or other applications where sound distribution or reinforcement is needed.
Voltera D Series seamlessly integrates amplification into a powerful loudspeaker controller that includes sophisticated tools for tuning rooms, resulting in a single, cost-effective networked solution.
A host of one-of-a-kind features drive flexibility, reliability and extraordinary audio performance. The combination of integrated DSP, high power and channel density, high efficiency and low idle power — along with support for power sharing and networked audio — delivers significant space and cost savings.
Available in 4 and 8 channel configurations from 1200 to 4800 W, the Voltera D Series is ideal for venues of any size, from restaurants to stadiums.
100% software configurable by Tesira or VenueTune software. VenueTune provides a phased workflow to guide system designers and installers, in-depth control through an intuitive graphical interface, and support for importing 2d backgrounds such as floorplans.


Voltera D M Series — like Voltera D — seamlessly integrates amplification into a powerful loudspeaker controller, while also adding a fully programmable DSP onboard with enough headroom to handle even complex audio processing and distribution needs.
The Voltera D M Series shares the benefits of Voltera D, while adding open architecture DSP, resulting in reduced wiring and device count, dramatically simplifying installations and reducing system costs further.
Available in 2 and 4 channel configurations from 600 to 4800 W, Voltera D M amplified loudspeaker controllers are perfect for smaller venues where their ability to replace an external DSP can have a significant proportional impact on the total system cost. However, larger systems can also benefit when more DSP power is needed.
100% software configurable, by either Tesira or Biamp VenueTune software, depending on user preference and audio network protocols, Voltera D M amplified loudspeaker controllers make setup and use easier.
