: Allen & Heath AH‑DX164‑W 16‑in / 4‑out Wall‑Mount Remote I/O Expander

Allen & Heath DX164-W – Description

The DX164‑W is a wall‑mountable I/O expander that adds remote input/output capability to compatible digital mixers or audio systems (e.g. from Allen & Heath). It’s designed for fixed installations (studios, theaters, houses of worship, schools, etc.) or stage floor pockets — ideal when you want remote mic/line inputs and line outputs some distance from the mixer.

Key Features

• 16 XLR mic/line inputs with preamps — provides ample inputs for microphones or line‑level sources.

• 4 balanced XLR line‑level outputs — useful for sending signals to mains, monitors, or external processors.

• Phantom power available per input — supports condenser microphones.

• Single-cable connection (EtherCon / Cat‑5) — links to mixer or upstream I/O expander, simplifying cabling.

• Redundant or cascade mode supported — you can either daisy‑chain another expander or keep a redundant link for reliability.

• Flexible mounting options — can be wall‑mounted, flush‑mounted (in-wall), floor-pocket mounted, or surface-mounted depending on installation needs.

• Multiple power options — accepts standard AC power or allows 12 V DC backup power for installations needing fallback power.

• Plug‑and‑play ready — no complex configuration required; once connected to a compatible mixer, it works out of the box.
