The broadcast industry is experiencing huge infrastructure changes, moving from proprietary to IP networks.
This can seem complex, but it needn’t be.
Many broadcasters still use proprietary systems, and with good reason; they’re intelligent, low latency, deterministic and discoverable! They already work!
But the ability to link up with third party IP equipment using AES67/SMPTE 2010-30 is bringing broadcast communities together. Calrec introduced its AoIP unit to enable Hydra2 equipment to talk to third party IP equipment over these protocols.
In fact, Calrec customers can even upgrade to IP using their existing equipment. Calrec’s powerful and flexible ImPulse core can be added to existing Apollo and Artemis control surfaces, and Calrec’s super-flexible Type R core can be used in a variety of ways.
Using the H2 IP Gateway, all Calrec equipment can sit on an IP network, a proprietary Hydra2 network, or a combination of the two which enables you to migrate to IP at your own pace.

Calrec’s H2-IP Gateway provides an interface between a Hydra2 network and an AoIP network. It awards an extra control level that allows audio labels to be passed in both directions between the two networks along with control data.
This gives Hydra2 users the ability to control gain of Calrec AoIP mic inputs, and AoIP users can control gain of Hydra2 mic inputs. The H2-IP Gateway is SMPTE 2110/AES67-compatible and expands Calrec’s range of AoIP solutions.
The 1U gateway can pass either 256 or 512 channels of audio in each direction and multiple gateways can be used to increase capacity or to connect with multiple networks. For full hardware redundancy additional units can be deployed as backups.
The Calrec Audio over IP unit provides a Hydra2 AoIP interface carrying up to 512 x 512 channels using AES67/Ravenna.
The unit can accommodate two modules and may be fitted with one or two 256 x 256 channel AES67/Ravenna modules, or one of each type as required. In addition to the standard Hydra2 redundancy each module also has both a primary and secondary 1GB IP connection, supporting hitless switching for redundancy.

AoIP Modular I/O Controller Card
Calrec’s AoIP Modular I/O Controller card fits into a standard modular I/O rack and can operate in either Hydra2 or AoIP mode. The mode is selected via a simple switch on the card making it dual purpose, allowing for it to be used on either network. Not only does this make a tailorable AoIP I/O solution for the ImPulse core, it also fits into existing Modular I/O frames so units can be upgraded in the field.
The card provides two redundant pairs of 1G SFPs to allow 512 audio channels to pass without over-using bandwidth in AoIP mode.
The AoIP Modular I/O Controller card is SMPTE 2110/AES67-compatible and expands Calrec’s range of AoIP solutions for new and for existing customers.
Dante/AES67 card with network redundancy
Calrec’s Dante/AES67 card provides an interface for routing audio in and out of a Hydra2 network into a Dante network. The interface is via RJ45 connectors housed within a 1-slot wide module.
Dante is a self-configuring, plug and play, digital audio networking technology developed by Audinate. Dante uses standard internet protocols. The Calrec Dante modular I/O card operates over Gigabit (Giga/E) Ethernet.
The card provides 64 input channels and 64 output channels (for a Dante network operating at 48 kHz or 44.1 kHz), or 32 input channels and 32 output channels (for a Dante network operating at 96 kHz) sample-rate converted down to 48kHz with the SRC’s permanently enabled on all channels.
Two RJ45 ports (primary and secondary) are provided to give full redundancy on the Dante portion of the network.
Waves Soundgrid IO card
Calrec’s Soundgrid card provides 64 outputs from the Hydra 2 network to the SoundGrid network, and 64 inputs to Hydra 2 from SoundGrid at 48 kHz via a single Ethernet cable.
SoundGrid is an Audio-over-Ethernet networking and processing technology developed by Waves. SoundGrid provides extremely low-latency, high-channel-count audio processing using standard Intel CPUs and 1 Gbps Ethernet networks for studio, live sound, and other real-time professional audio applications.
Real-time audio processing is performed on standard Intel-based plug-in servers, running a Waves-customised real-time version of Linux.
