Audio Input Signal
•

•

LEDs
POWER - Constantly lit red to indicate the device is powered on.
ACTIVE - Illuminates green when a loop is being driven correctly.
OVERDRIVE - Becomes increasingly steady red as an audio signal in-
creases. If it is continuously red, the drive level of the loop is too high
and audio may be distorted.
If the ACTIVE LED is not illuminated and the OVERDRIVE LED is con-
stantly illuminated, the induction loop is disconnected or open-circuit.
Remedial action must be taken.
