I/O Modules

We translate our approach of maximum flexibility and modularity to the I/O side of the DHD system. We support the latest industry standards for audio signal exchange – everthing from standard analogue and digital interfaces over different multichannel solutions to completely IP-based audio networks.

Together with our well-established control signal interfaces you have all options to integrate the DHD products into your preferred infrastructure. You are not limited to a fixed amount of connections, but can add as many I/O boxes to the DHD system as required.

For advanced flexibility in device connectivity, each DHD Core can be equipped with a AES67 RAVENNA Interface (52-7567A). Also a Dante™ Audio-over-IP interface (52-7580A or 52-7585A) is available.

With the AES67 RAVENNA interface, you can use up to 128 channels of uncompressed, bidirectional audio to connect to almost any other Audio-over-IP device like codecs or signal processors via a standard ethernet network. The Dante interfaces supports up to 512×512 channels.

Transmit dozens of signals over one single cable with the following solutions:

• MADI/AES10 with 56/64 channels over fibre-optic cable
• 3G/HD/SD SDI with 2×8 channels over coaxial cable
• DHD APC with 48 channels over standard CAT5 cable
• DHD Gigabit Audio with 512 channels over fibre-optic cable

Our high-quality digital and analogue modules allow you to connect your devices with classical I/Os:

• Digital AES3/EBU XLR input/output with sample rate converters
• Analogue line XLR input/output with up to 24 dBu
• Microphone inputs, supporting individual switchable 48V phantom power
• Headphone outputs

There are several possibilities to get signals and logics in and out of the DHD system by means of

• DHD control API
• Ember+ Protocol via network
• DHD External Protocol via network
• GPI and GPO (General Purpose Input/Output) via D-Sub
