Arista Corporation has introduced the E-Vocal Duo+ Audio-over-IP product group with three units – the E-Vocal Duo+ product group comprises the ARS-0202-A00 analogue-to-Dante-to-analogue audio interface, the ARS-2020-A11 dual XLR microphone-to-Dante interface, and the ARS-0202-B11 dual XLR microphone-to-Dante interface with an SFP connector fibre interface.
The E-Vocal Duo+ ARS-0202-A00 connects legacy audio gear to the Dante world. It supports two channels of analogue audio to be integrated into a Dante network and also converts a Dante stream into two channels of analogue audio output signal. This interface is equipped with an RJ45 copper network interface.
The Arista E-Vocal Duo+ ARS-2020-A11 and E-Vocal Duo+ ARS-2020-B11 are both dual XLR microphone-to-Dante interfaces for dynamic and condenser microphones. Two audio signal outputs enable lip-sync delay of up to 170ms/ch (fs 48kHz) to synchronise the audio stream to the video stream. Both units have a built-in web-based controller for microphone gain control and Lip-Sync delay control. The E-Vocal Duo+ ARS-2020-11 is equipped with an RJ45 copper network interface while the E-Vocal Duo+ ARS-2020-B11 has an SFP connector for Fiber interface, which is ideal for those times when it becomes necessary to extend the connection distance.
The copper interface units (E-Vocal Duo+ ARS-0202-A00 and E-Vocal Duo+ ARS-2020-A11) can be powered via PoE (Power over Ethernet) or 12V DC, while the fibre-equipped E-Vocal Duo+ ARS-2020-B11 interface is powered by 12V DC. The Arista E-Vocal Duo+ interfaces were designed for harsh stage conditions with lockable XLR and etherCon connectors for both the audio and network connections. The E-Vocal Duo+ interfaces have rubber protection shells and rackmount brackets as optional items.
The E-Vocal Duo+ feature set includes lockable audio and network connections, being AES67 compliant, using high resolution 24-bit analogue-to-digital conversion, plus dual power input options including a Power over Ethernet switch, PoE injector (802.3 af/at class 1), or DC 12V. As Dante-enabled devices, the E-Vocal Duo+ products deliver bit-perfect audio reproduction and offer super-low latency and sample-accurate synch across an entire network.
‘The E-Vocal Duo+ interfaces offer a wealth of functionality, with two models specifically designed to accommodate dynamic and condenser microphones,’ says Arista Corporation President, Paul Shu. ‘And with the E-Vocal Duo+ ARS-2020-B11 having a fiber connector, technicians have the freedom to cover longer distances if needed. I have every confidence that audio and video technicians will find these interfaces both versatile and very beneficial.’
Arista’s E-Vocal Duo+ Audio over IP product group is expected to become available Q4 2019.
