Sennheiser SKM AVX Reviews

The is a power down switch at the base.

By Alan

The AVX system is remarkably easy to use, reliable, and interference free, and has pretty good range (100 ft line of sight.) There is about a 8ms delay which can be annoying in PA, and has relatively high distortion for music (not noticeable in talking.) Battery life is good at about 4 hours (limited by the receiver.) The mic capsule is susceptible to any condensing moister and will short out some active electronics in the head.

Does not feel like Sennheiser quality/poor deisgn

If you are like me you already own the older SKM handheld set and want to save some money by taking the old capsule and putting it on the new transmitter (I already owned the AVX lav kit and wanted to add the handheld mic). No problem there but the transmitter feels cheap compared to the older SKM unit. For some reason they decided to cheat you out of a mute button on this unit as well. When you buy the unit with the capsule you get a mute button. There is also no way to power down other than pulling the battery. I am enjoying the mostly interference free signal of the AVX series but the build quality has taken a step back. Don't let anyone drop this mic or you will probably be buying a new one.
