A somewhat better electronic system on these receivers and transmitters which have LCD displays so changing frequency is now a push button operation ..I also have the older L100 system that used 9v batteries where the 330 uses AA's

Sound quality is great on this dual receiver system ..I would have really liked to have a nice "back of the camera" mounting arrangement as the receiver only has a cold shoe mount.

Like my older Azdens I turn the standby switch to "audio" and cover it with tape so it can be never turned back to standby as I almost lost audio at a wedding cos the priest fiddled with my transmitter.

Love Azden quality and performance...A+++++ gear!!!
