Page 20: 6D. Agc
PLA DL210NET Digi-Loop™ DSP Induction Loop Amplifier 6d. AGC Automatic Gain Control measures the average level of the signal and applies gain reactively to keep the output level constant. It also limits the output power and reduces or eliminates distortion due to clipping that would normally occur without AGC. 6d1-6. -
Page 21: 6E. Delay
PLA DL210NET Digi-Loop™ DSP Induction Loop Amplifier 6e. Delay Delay is the amount of time between the input signal and the output signal of the amplifier. This is often useful in a loop system when a PA system is also being used, so that the audio being heard through the loop (receiver or hearing aid) matches that of the PA System speakers. -
