Shure A15TG Tone Generator

Battery-powered 700 Hz tone generator that troubleshoots audio systems by checking microphone lines for correct patching and detecting unusual noise.

The A15TG includes a recessed On-Off switch and a three-pin XLR audio connector. A removable end cap allows easy battery installation and removal. The A15TG can also tolerate the presence of phantom power, or a short circuit in the line it is driving. Built-in short circuit protection allows normal operation to resume after a short is removed.
