Complimenting the dLive Series of products from Allen & Heath is the DX32 Modular I/O Expander. This DX Expander allows you to add remote, modular I/O to a dLive system. It provides 4x 8ch slots to fit a selection of analog or digital I/O. Up to 2 DX32 Expanders can be connected to the MixRack, and a further DX32 can be connected to the Surface.

The DX32 is a fully modular expander that features 4 slots for 8 channels of high end, low noise microphone preamps, 8 analog outputs, 8 AES/EBU (32-192kHz sample rate, stereo) digital inputs & 8 AES/EBU (44.1, 48, 88.2, 96kHz switchable per output) digital outputs. The DX32 has slots for 1 or 2 hot swappable redundant power supplies and a unique auto firmware matching feature keeps the DX32 in sync with the rest of the dLive system.
