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 au-
dio 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 al-
lows normal operation to resume after a short is removed.
BATTERY LIFE
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.
