    I bought the CT-100 to verify that some of my XLR cables are indeed bad. It showed me that one of my XLR's definitely had some serious issues, and that my other ones were okay. It was very easy to use, and testing did not take long at all.

    Getting ready to test, however, was not fun. The battery cover is screwed on, and my partner had a difficult time unscrewing it. The included belt clip goes right over the battery cover. I thought it would be much easier on the user to not have to unscrew so many screws to get to the battery. The optimal number would be 0.

    I haven't used the other features on there, yet, but it's good to know they're there. I do like the fact that it's so much cheaper than the next competitor. I am willing to forget about the whole battery cover thing and just tape it up.

    Overall, I think this is a good enough product to make me recommend it to everyone.

    Having a cable tester is an important piece of gear for a musician, a live sound reinforcement engineer and audio/visual videographers. This unit has its place. The battery compartment relative to the belt clip is awkward. The multi-level functions are difficult to understand for a non electrically trained professional.

          Comments about Behringer CT-100 Cable Tester:

          I bought the Behringer CT100 cable tester because I make all my audio cables and want to test them before they are connected to a device. If you only plan on testing "balanced XLR" or "unbalanced phono" connections this device is a good product, order it now and stop reading. If you want to fully understand the logic and full implementation of the Behringer CT100 please continue reading.

          The Box

          The overall quality if the inputs and output connectors is good. The box is solid and compact and with the purchase of other adapters like an XLR (male) to T3A (male) connector you can test other cable connectors, extending the usefulness of the tester. I also like the fact that this tester included the 1kHz test tone feature, but as other reviewers have stated the battery door and belt clip is the weakest elements in the design.

          Additional Parts

          As a device it requires other stuff to put it into use. You will need 2 AA batteries and a small Phillips head screwdriver. A replacement screw for the battery compartment would also be handy, a small flashlight if you work on location and some type of storage container to hold all the equipment needed to change the batteries.

          LED Display Logic

          Behringer states on it's packaging that this device has a "super-easy operation with intuitive LED display." I would agree that it is easy to plug in the connectors, but I do not agree with the "intuitive display." To understand the LED pattern array, the manufacture should have printed common visual test examples on the last page of its user guide, (which is a blank page). Visual displays are better with "informational keys" to better understand both the information and the logic of the visual code. As example, a road map without a size or distance scale would have some utility, but would be more useful with the other information. As a side note if you are interested in "visual explanations" please see the works by Edward Tufte. His books on 'The Visual Display of Quantitative Information' and 'Visual Explanations' are eloquent.

          Cable Testing

          The cable testing functions worked well, but I did not have any damaged cables to test. The cable testing display contains a 9 LED lights/cells display that is similar to a "tic-tac-toe" board. A well made "balanced cable" will light up 3 LED lights running diagonally from the upper right corner to the lower left corner of the light array. If you are testing XLR connectors and pin 1 is grounded to the XLR chassis the "grounded shield" LED will light up.

          Test Tone Generator

          I also tested the CT100 1kHz test tone generator (-50 mic level signal output) by recording it and comparing it to the 1kHz tone at mic level sent from a Sound Devices 442 field mixer. Both signals were recorded using the same gain structure. All three devices had new batteries installed and I found that the Behringer 1kHz tone produced an –5.3 dB signal compared with the –0dB signal from the Sound Devices mixer. While this test is far from conclusive it would be useful to test your CT100 against another piece of professional grade equipment.

          Conclusion

          While I do think this device will be useful, the company should improve the quality and quantity of information in both the user manual and the website.

            Comments about Behringer CT-100 Cable Tester:

            I've only used a 1/4 cable to test it. So far it works but I had an issue to put batteries in the back. You need a mini screwdriver which I did not have. So I had to buy one. I had another issue where I had to perform and I had a short in my pedal board. I used the cable tester and found which cable was faulty. However, after I fixed the cable, the tester said it was fine and once I placed it back in the pedal board, it still was messing up. So I had a backup cable and use that instead. So I don't know if I would recommend this but I'll give it another try.

                  This device is well built and easy to use. There is the unusual issue of the belt clip blocking the battery compartment but that is a minor inconvenience.

                  Checking out cables is simple and effective but this box earned it's price at its first live gig. I had no sound through a bass guitar DI box. Checking cables was going to be hard due to length and location of the runs. I used the built in signal generator and quickly located the problem as the DI box. I replaced it with a backup and no more than a few minutes was lost.

                  Its a simple device but when you need it, you need it. I have no complaints!

                      Quick and easy way to check cables. My one nit to pick is the battery compartment door requiring a screw and the fact that if you use the belt clip, it blocks access to the perviously mentioned screw. A small quibble really. I'd still buy it. Besides checking my old XLRs, I use it to check that the ones I make myself are functioning properly.

                      I'm both a live performer and roadie so need to be able to rely on my equipment. The CT-100 makes sure your cables aren't a problem any more. I use George L solderless cables so this is a very good check on quality of assembly (they are finicky but the best for signal when assembled right). Great piece of mind for small price.

                            A good inexpensive way to test you cables, but I bought it for the tone generater. It is fairly small, lite, portable, and generates tone. I use it to set up levels at location shoots between mixers and record decks. Sure the plug in sticks are 1/4 the size and more portable but the price of the Behringer is 1/4 that of a tone stick and it checks your cables too.

                                Cables, after years (or sometimes months) of use tend to develop issues. As did mine. Yes, any multimeter with a continuity settings will let you check your cables, but what a PITA to check all leads and pins that way. The Behringer CT (Cable Tester) really makes it a quick and easy task.
                                Best part for me really is the 'wiggle test'. Many cables test OK when plugging them in but then in use, when they're moved (I work in the movie business where cables are constantly moved) faulty connections might only show up when the cable's under duress. And that's where the CT-100 shines. Plug in the cable, move it all around and it will show you if there's any issue - even only for a fraction of a second. GREAT!
                                I immediately replaced a few connectors after my first test run and put some other cheap cables into the trash.
                                This thing is totally worth it's money.

                                Well, there's always a wish list: the CT-100 tests all common cables. Would I like to have some more esoteric and specifically hard to test connectors on there? YES. Like 'lemo' connectors, mini XLRs in all pin formations and so on. But hey, I don't think such a gadget exists - no matter the costs.

                                  I use it for guitar cables. It is easy to use and a good value.

                                        i Have used more expensive testers in the past. For a quick check of a cable you cannot go wrong with the inexpensive piece

                                            This unit has made my job so much easier when dealing with troubleshooting audio problems on the platform at my Church. Sometimes it's a mic cable, sometimes it's a mic connector and when the cable shows okay on this little tester, then I look at the connector on the platform. Sure takes the guesswork out. This unit is small, has a belt clip for hands-free operation.

                                              Unit works very well, If you wiggle too hard you may trip it up, but with the right touch its great. The directions could be written better to include the different patterns and what they mean.

                                                As I do live sound for a couple of bands, this is a must have in my toolkit. Great little tester for doing just the basics. Seems well constructed, and I trust the Behringer name.
