EC WIRELESS MICROPHONE SYSTEMS

GENERAL

The

Shure EC Series wireless microphone systems are confi
gurable, single-channel systems operating in the VHF band be­tween 169.445 MHz and 216.100 MHz. All EC systems feature

Specification Sheet

With MARCAD, the EC4 constantly monitors signals on each of
two receivers and combines them when both signals are usable.
The result is increased

freedom from dropouts. The EC4 also uses PLL frequency
