A replacement for the popular Sadelta EchoMaster base microphone.
Sliders provide adjustment for both volume and echo level. A preset underneath the mic allows adjustment of the echo delay.
A switch on the rear of the mic allows you to turn the "roger bleep" on or off.
The meter indicated output level (volume) and there is an adjustable neck (with wind-shield).
Powered by a 9V PP3 battery (supplied).
