The SoundTools CAT Rack is a rack mount stage box capable of delivering up to 12 channels of audio and data from XLR or DMX sources over three CAT cable lines. Fully passive, these all-analog stage boxes are customizable to deliver the best in audio and data without interference or signal loss.



The SoundTools CAT Rack is the ultimate in rack-mounted XLR-to-Cat stage boxes. Twelve XLR ins or outs (call us for custom builds) line one side of the unit, and 3 pairs of etherCon ins and outs (6 connections total) are on the other side. CAT Racks are all-analog and designed with machined anodized aluminum and stainless steel screws for ultimate durability. When used with shielded Cat5e cable or better, the CAT Rack allows for the use of phantom power.


Easily reverse the rack ears to change which way the rack is mounted by unscrewing the two screws on each side.



Mount your CAT Rack on standard 19" rack rails, using the reversable ears for XLR or etherCON side out (remove screws to reverse rack ears). Attach your shielded CAT5 cables in the input or parallel etherCON connection on the back of each section of the CAT Rack. Attach your XLR cable ends to channels 1, 2, 3, or 4 in each section A, B, and C. Now you can run up to twelve lines of audio down three shielded CAT5 cables.

Pair with an additional CAT Rack, CAT Snake, CAT Rack, or WallCAT to send and receive four lines of balanced audio.

Do I need to use shielded CAT5 cable?

Yes. Each of the channels share a common ground. This is especially important with digital signals.

How far can I send a my mic lines?

For balanced analog we've achieved distances of over 600ft using our SuperCAT cable. The results will vary with other CAT5 brands. For digital signals we reccommend distances up to 330 ft as per AES/EBU standards.

Can I use the CAT Rack with the SoundTools CAT Tails or CAT Box?

Absolutely! All of the RATCAT family will work together, bringing audio over CAT to the places you need​ it most. Connect CAT Box to CAT Tails or CAT Racks, split signals using the parallell/thru jacks, and route your audio where you want.

Can I send audio in both directions or do I need another gender CAT Rack?

Absolutely! All of the RATCAT family will work together, bringing audio over CAT to the places you need​ it most. Connect CAT Rack to CAT Tails or CAT Box, split signals using the parallell/thru jacks, and route your audio where you want.

Is shielded cable really required?

The short answer is no. But in order to use phantom power and to minimize noise, we strongly suggest you use properly shielded cable. You can check if your cable is shielded by checking for continuity on the RJ45 jack using a multi-meter. Still not sure? Just purchase SuperCAT and you know you'll be covered.

Can I use it with my (digital console)?

While the CAT Rack will work with any console on the market, it is important ​to note that it does not do any D/A conversion. The beauty of the CAT Rack is that it sends analog audio over lightweight CAT cable, no conversion required. Hook directly up to your XLR connections and let CAT Rack do the rest.
