What to know before buying

Listing details to confirm

The listing is inconsistent about connections: its details identify USB 3.0, while the title and feature text describe an RJ45-based audio extender with XLR and 6.3mm sockets. Confirm the actual ports and cable arrangement before buying. The listed Cat 5e category is not a supplied cable, and the stated shielded-cable feature conflicts with the explicit note that no cable is included. Claims of indoor and outdoor use do not specify weather protection.

Who is it for?

A good fit for

Audio setups needing to route four analogue signals between a mixer, microphones or instruments and remote equipment using a separately supplied RJ45 cable.
Stage, studio or lighting users looking to reduce multiple long audio-cable runs.

Less suited to

Buyers who need a network cable included.
Anyone seeking a USB extender or a product whose RJ45 connection details are confirmed without checking the listing.

Consider the stated four-channel routing and connection details against your setup, and clarify the connector inconsistency before relying on it.

Frequently asked questions

Does this pair include the RJ45 cable?

No. The listing explicitly says the cable is not included, so a suitable cable must be sourced separately.

How many audio signals does it carry?

The feature text claims that the pair routes four analogue XLR audio signals over one RJ45 network cable.

Can it accept 6.3mm connections?

The listing describes a female unit with a 6.3mm socket as well as XLR. Because its connector details also list USB 3.0, confirm the actual connection layout before purchase.
