The Allen & Heath GX4816 audio expander 48×16 I/O for SQ / Avantis / dLive / AHM is a rack-mountable remote audio device for Allen & Heath mixing systems. The remote audio unit features 48 XLR inputs with individually configured phantom power and 16 XLR outputs. Phantom power LED indicators are provided for each input jack on the remote audio rack. The unit operates at a sampling rate of 96 kHz. An Ethercon connector is provided to carry digital audio and control signals to and from the mixing system. Two additional Ethercon connectors are provided for further expansion with Allen & Heath compatible remote audio devices. One of these ports is compatible with Allen & Heath’s ME personal mixing system when the device is used with an Allen & Heath Avantis or SQ digital mixer. The Ethernet protocol provides control to the remote preamplifier, and all mic preamps are callable from the digital mixing system. The unit’s firmware is automatically updated when connected to the system. The remote audio rack has a built-in power supply that accepts AC mains voltages of 100~240V, 50/60 Hz, 80W through a grounded 3-pin IEC male connector on the front panel.
Flexible connections
Allen & Heath’s audio expanders offer flexible inputs and outputs for advanced configurations. They can include XLR, TRS and Dante ports for digital audio networks. These devices expand the capacity of mixers, providing a greater variety of audio sources and destinations. AES3 and S/PDIF connections are often present to ensure superior audio quality in professional settings.
Audio transmission via Dante or S-Link
Allen & Heath’s audio expanders offer a wide range of inputs and outputs, with configurations such as 16 or 32 XLR inputs and 8 or 16 XLR outputs in modules such as the DX168 or GX4816. Connections include Ethernet ports, for audio transmission via Dante or S-Link, and AES outputs for high-quality digital audio transmission.
Advanced compatibility and integration with audio network systems and mixers
Allen & Heath’s audio expanders offer great compatibility with Dante, AES67, S-Link, and MADI protocols. They allow integration with audio network systems and mixers such as dLive, Avantis, and SQ. They support connection via Cat5e or fibre optic to expand inputs and outputs. This flexibility makes them ideal for complex live and broadcast installation applications.
