Portable loop kit C
The Portable loop kit C covers up to 170 square metres. The built in AGC circuit maintains a clear and constant level of sound; this helps pre-vent the hearing aid from distorting.

Features
Constant Current Output - Compensating
automatically for changes in loop impedance.
Conforms to BS6083 pt4.
Auto compensates for field strength changes
Loop sizes from 1m2 to + 170m2
Single turn loop
One VHF radio microphone module (TOA WM3810)
Twin microphone input and one auxiliary input

Automatic Gain Control (AGC)
To optimise sound quality the integral DLS380 induction loop amplifier has AGC. The AGC circuit increases the level of quite sounds and decreases extra loud sounds. This enables the output of the induction loop to maintain a clear and constant level of sound for the hearing aid user.
