The rugged DX168 Portable DX Expander from Allen & Heath adds remote inputs and outputs to the dLive S Class or C Class mixing systems. It features 16 XLR mic/line inputs, with independent phantom power LED indicators, along with eight XLR line outputs. The expander connects to the dLive system via a Cat 5 cable (sold separately), allowing for the inputs and outputs to be positioned up to 330' away from the mixer.
