Voltera D series amplified loudspeaker controllers are available in 1200W 4-channel, 1200W 8-channel, 2400W 4-channel, and 2400W 8-channel configurations. They feature support of audio via AVB, Dante, and AES67. Dante can be dual redundant.

All models of the Voltera D provide high power and channel density while maintaining high efficiency and low idle power. They are capable of high peak voltage output and can deliver up to 75% of the total power on any channel using power sharing. They also offer both Lo-Z or Hi-Z per channel to support hybrid systems.

Configured by either the Tesira or VenueTune software, the Voltera D series is ideal for a wide variety of applications, from houses of worship to transportation.
