Description
The Shure A15TG Tone Generator is a battery-powered 700 Hz signal source that can be used to troubleshoot low-impedance, balanced-line microphone inputs.
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.
The A15TG can operate continuously for approximately 1000 hours on one 1.5V alkaline battery. To conserve battery power, make sure the On-Off switch is in the Off position when the A15TG is not in use.
Features:
- Produces a continuous 700 Hz mic-level signal capable of driving low-impedance, balanced lines.
- 1,000 hours of battery life under continuous use
- On/Off switch
- XLR male output
| Output Frequency | 700 Hz +- 20%, when terminated with 150 ohms |
