Description
The DX164-W is a wall mountable expander that adds remote I/O to a dLive, Avantis or SQ mixer, or to AHM audio matrix processors.
Wall or Floor Mount
The reversible mounting frame allows for in-wall or on-wall mounting. With custom brackets, the unit can be fitted in a standard NEMA box, or mounted in a floor pocket for stage use.
Maximum Flexibility – Put It Where You Need It
The DX164-W can be placed up to 100m away from the mixer for maximum flexibility of positioning. The expander connects via a single Cat5e cable to the mixer or upstream DX Expander via a secure EtherCon port. A second locking EtherCon port is provided for redundant connection to compatible hardware, or for daisy-chaining to a downstream DX Expander for additional remote I/O.
Flexible Power Options
The IEC mains power inlet can be replaced with a gland module and screw terminals for fixed installation, and a DC 12V backup input is also provided.

Been using this for a few weeks now and the product works but the quality isn’t as good as I hoped. It’s passable.

Decided to try this after seeing the reviews and love the product! Took off one star because packaging could be better.

I’ve had this for a couple months and solid product. Would be perfect if it came in more color options.

Been using this to replace my old one and perfect in every way. I’ve been using it for weeks now and it still works like the day I got it. Will be ordering more.
