Arista Corporation, in conjunction with DMX Pro Sales, announced the availability of Arista’s E-Vocal Duo Audio-over-IP interfaces. The models (available on Amazon) include the ARS-0002-A00 Dante-to-analog audio interface and the ARS-0002-A01 interface, which facilitates lip-sync delay to enable sound and picture to be synchronized.

Arista’s E-Vocal Duo ARS-0002-A00 converts a Dante stream into two channels of analog audio signal. This interface is useful when, for example, a stereo feed of the performance is needed to feed a conventional sound reinforcement system or is to be recorded. Arista’s E-Vocal Duo ARS-0002-A01 allows two audio signal outputs of Lip-Sync delay of up to 170 ms/ch (fs = 48 kilohertz) to synchronize the audio stream to the video stream. The delay control switch can add delay in the range of 0~170ms by 32 increments. The E-Vocal Duo ARS-0002-A01 uses XLR analog outputs.

Arista’s E-Vocal Duo products are AES67 compliant, using high resolution 24-bit analog to digital conversion, and the ability to be powered via PoE (Power over Ethernet) or 5VDC via a Micro USB connector. As Dante-enabled devices, the E-Vocal Duo products deliver bit-perfect audio reproduction and offer super-low latency and sample-accurate synchronization across the entire network. As Dante-enabled products, the E-Vocal Duo products make it easy to use one’s legacy audio gear with any Dante-connected system — delivering the interoperability, performance and scalability that only networking can bring.
