The sound is rolled ... Breath, building high mids, bass loss. The automatic squelch fits poorly. Preamp integrated catastrophic: when you push the gain, that blows! Yet I use with AKG microphones designed for this type of system. One strong point: autonomy. But clearly, the consolidated low is clearly detrimental to the quality of the preamp and the rest of the electronics. I compared with the Sennheiser EW100: nothing to do.
