Allen & Heath DT164-W 16×4 Wallmount Dante/AES67 Audio I/O Expander


The Allen & Heath DT164-W is a 16×4 wallmount Dante/AES67 audio I/O expander offering tight integration with dLive and SQ Series mixers for live stage applications such as houses of worship, concert venues, and theaters. It features 16 low-noise microphone preamps and four line outputs, all on balanced 3-pin XLR connectors. 48V phantom power is selectable per input while 16 LEDs indicate the phantom power status for all inputs. Internal 96 kHz converters deliver the detailed audio quality and high resolution that modern productions demand.

The primary and secondary etherCON ports boast a locking mechanism to prevent accidental disconnection and allow simple hookup to your Dante or AES67 audio network. Directly control gain, pad, and phantom power settings for the DT164-W’s preamps via your dLive or SQ mixer. With primary and backup powering methods and multiple mounting options, the DT164-W is well suited for permanent installation in small- or large-scale venues.
