    Description:
    The SCOM® DADM is a digital audio delay module intended to be installed into repeater controllers or used stand-alone. Its delay time is programmable from 12 to 197mS set with DIP switches. It has compatible mounting holes for easy installation into S-COM 5K, 6K, and 7K controllers as well as some conventional ICS repeater controllers. It comes with a 5 conductor ribbon cable that accommodates the COS connection as well as power, audio and ground.

    Why do I need it?
    A audio delay board will fully mute DTMF tones and can eliminate a squelch crash after a user unkeys. This module has audio muting to be compatible with other repeater controller manufacturers. It requires a connection to COS logic. Both active high and active low are compatible and selectable by DIP switch programming.

    NOTE -Some component values were changed from original for universal compatibility.
    C2, C19, C21, and C22 are now 10uF 25V MLCC capacitors - Q1 and Q2 are now 2N2907.
    All other components are identical to the original (legacy) SCOM and ICS branded DADM boards. Performance is as good and possibly better than the original.
