Show Larger Photo

Battery-powered 700Hz signal source that can be used to troubleshoot low-impedance, balanced-line microphone inputs. Recessed on/off switch and 3-pin XLR audio connector. Removable end cap allows easy battery installation and removal. Can also tolerate 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.

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.
