The Telex TT-16 transmitter is equipped with E.D.R., Enhanced Dynamic Range (companded) au- dio. This mode greatly improves the Audio Signal to Noise Ratio when used with the Telex Model TR-16 receiver. The E.D.R. mode must be selected on both the transmitter and receiver to be effective. If using the TR-16 with a TT-44 IFB Transmitter, E.D.R. must be turned off.
