Glensound DARK16O

16 Analogue Outputs To DANTE/ AES67 networks

The Glensound DARK16O is a versatile break out box for receiving analogue audio from a network utilising the Dante and AES67 audio over IP (AoIP) protocols.

In total there are 16 channels of audio being received from the AoIP network and converted via low noise DACs (Digital to Analogue Converters) to balanced analogue outputs.

For ease of cabling audio outputs are presented as balanced circuits on Neutrik XLRs.

Being designed for resilient broadcast applications the DARK16O features both redundant power supplies and redundant Dante network links with link status GPOs (general purpose outputs (solid state relays)). Both primary and secondary network links are provided with both magnetic (copper RJ45) and fibre (SFP) interface connections. The Dante system itself provides a completely transparent redundant link system which means that if the DARK16O lost its primary link circuit, the secondary link would automatically take over with no loss of audio.

The primary and secondary network interfaces are routed internally via a network switch.  It is possible to set this switch to work as a traditional network switch instead of the default redundant mode.  This means that there would be just one link to the Dante/ AES67 network and the other connections of the switch could have other Dante or network devices connected to them. As with all Dante devices, once set up, DARK16O units can be directly connected with each other with no external network hardware.
