Countryman Isomax 4RF Reviews

Rich Sound - Hot Response

By Mark
Rated 5 out of 5
Date: 2017-08-14

I have two Isomax 4RF microphones used at church. The 24-inch Cardioid we use at he Lord's table and a 18-inch Supercardioid on the podium. Compared to numerous other brands, the Isomax is very tolerant of feedback, has a very rich tone even using a flat EQ and is hotter than comparable microphones. While we need acoustic panels to improve clarity in our auditorium, this microphone help significantly to overcome the loss of clarity due to poor acoustics. It is a great microphone and comes in a plastic tube for protection. Another attribute is it ability to not pick up background noise from bumping the podium.
