Kopul CTSS-2 Overview

Designed for studio, stage, and field applications, the Kopul CTSS-2 Double Barrel XLR Cable Tester is an indispensable tool for audio professionals. It offers a dependable solution for verifying the functionality of XLR cables, helping to prevent potential issues during live performances, recording sessions, and other critical audio operations. The CTSS-2 includes two units: an XLR Input module and an XLR Receiver module.

Remote Cable Testing Made Easy
The XLR Input module, powered by an A23 battery, sends a signal remotely to the XLR Receiver module attached to the other end of the cable. This eliminates the need to bring cable ends together, enabling technicians to test and troubleshoot, even complex XLR cable systems across a stage or room in seconds.
Quickly Identify Problems
Three easy-to-read LED indicators (red and green) on the receiver instantly display whether a cable is functional or faulty. An included sticker guide clearly explains all possible LED combinations, making troubleshooting intuitive and foolproof. Stick the guide to the receiver for quick access.

  • Crossed wires: When the signal paths are mixed up.
  • Short circuits: When two or more wires are touching.
  • Open circuits: When a wire is broken or disconnected.
Quick Testing for Multi-Channel Snakes
The CTSS-2 excels in environments with multi-channel XLR setups. Using phantom power from a mixing console or audio interface, technicians can test multiple lines quickly. Simply pop the receiver in and out of each channel in the patch bay for rapid diagnostics.
Built for Durability
Constructed with a rugged, all-aluminum housing and a matte black finish, the CTSS-2 is designed to withstand the rigors of professional use. The A23 battery ensures long-lasting performance, providing reliable power whenever you need it.
Protective Storage
The reusable box included with the CTSS-2 protects both the Input and Receiver modules during transport and storage. Keep your units scratch-free and ready to use, whether in your gear bag or a drawer.

Kopul CTSS-2 Reviews

Must have this on Set or Stage.

I'm a filmmaker and also a freelancer going to other people's sets as well as theaters and band concerts. That means, the cables that they give me can be worn, defective or damaged on the wire or the plug. Or maybe someone did a bad job in attempting in repairing the cable, solder broke, causing shorts and even by inverting the connections. The Kopul CTSS-2 Double Barrel XLR Cable Tester will tell you exactly what the problem is. Simply plug it in and there's your answer instead of guessing what could be possibly wrong with that cable...Especially on large / busy Stages, bands, and movie sets there is a chance of finding bad cables around. Comes in a nice box, foamed, requires a battery and it is included so you don't have to buy anything extra the moment you unbox it. It also comes with an adhesive sticker that you can place on the unit so you don't have to bring the manual with you. (Product pictures I've uploaded are available to view when you are on the BH site via desktop). [I have received this product in exchange for my honest review]
