[24-33VDC@60mA] Used this to build a relay box for a club so that a spotlight turns on when the DJ starts playing. Works as advertised. Don't forget to order the 24V power supply too.

[24-33VDC@60mA] I buy these fairly often for several different applications. They are tremendously reliable and allow low voltage control.

[24-33VDC@60mA] Quick way to add a self powered sub to a 70v system. Also have fed a main PA the E-page system before. Works perfect!

[24-33VDC@60mA] Cleaned up the unclear paging and brought everything up to a clean and understandable level.


Amazing how changing the impedance cleared up the announcements.

[4.1 x 2.1 x 2"] This product arrived in new condition and worked as advertised.

[4.1 x 2.1 x 2"] Allows balanced audio over long runs where destnation terminal is unbalanced. Reduces/removes induced noise on long run.

[4.1 x 2.1 x 2"] The ACRs we use are needed to prevent noise from being injected into the paging systems output when not needed. They control the proper output from our security voice output when it is needed. They work really well for that need. Can not think of anything bad about the units.

[4.1 x 2.1 x 2"] This unit performed as described. However, I needed one that had a much shorter delay so I returned it and promptly got a refund.

[0.7 lb] Best solution for boardroom projectors. Nice and powerful given the footprint. Good full range sound. Has an imbedded condenser that causes a little hiss, back off the gains and increase volume with the source equipment.

[0.7 lb] This is basically a reverse DI-box. Our church has two of these devices which we use to feed audio from our worship services to other parts of the building. One of these endpoints optionally accepts a balanced signal, but doing so caused a ground loop. We're using the TX-1A to isolate that connection. The other endpoint is a cheap Radio Shack paging amplifier which only accepts an unbalanced input. The TX-1A does the job there as well. The built-in attenuator is a big bonus, allowing the use of cheap consumer -10dBV gear (such as our paging amplifier). One thing to note, the devices we received have Phoenix connectors instead of standard screw terminals. This is actually better in my opinion, since those are a bit easier to work with. But just wanted to point out the difference from the item as pictured.
