MODEL A15TG MICROPHONE LEVEL TONE GENERATOR
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 con-
nector.* 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.
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.
BATTERY INSTALLATION
1. Unscrew the end cap.
2. Insert the battery with the "+" terminal facing the "+" mark inside the end cap.
3. Reinstall the end cap.
*Mates with Cannon XL series, Switchcraft A3 (Q.G.) series, or equivalent.
