PROLOG select

In combination with a PROLOG control unit, the VIVANT offers full connectivity and additional features such as room correction and lossless signal transmission.

Digital & Analog XLR Inputs

The VIVANT offers digital and analog inputs for maximum sound reproduction quality in every setup. For the best possible sound quality, the digital input is used with a PROLOG control unit. The digital audio signal is then transferred to the speakers losslessy, either via XLR-cable or WiSA wireless technology.

Bluetooth aptX

Bluetooth aptX is the easiest and fastest way to connect your smartphone and stream music in high quality.

AirPlay & DLNA

For full wireless connectivity, both AirPlay and DLNA are supported by the PROLOG. Music can also be easily streamed to your VIVANT using the various integrated services, such as Spotify Connect, Tidal, Deezer or TuneIn Radio.

Wireless Signal Transmission

It is now also possible to losslessly stream music from the PROLOG control unit to LOG speakers using WiSA wireless signal transmission. This means that there is no need for a digital XLR-cable, making it even more comfortable to install and to use. With 24bits at 48kHz/96kHz, it's also twice the quality of CD audio at almost no latency.
