I decided to give this 'vocal' monitor a go for my solo act as I'm driving around in a small car nowadays and space for equipment is at a premium.
First up, it fit easily onto a spare mic stand.
Then it worked immediately when I connected it up to the phones output on my Dynacord mixer.
I have everything going directly into the PA (guitar processor, keyboard, vocals) which the speaker handled easily.
The sound was very clear, no crackles, distortion or feedback from the mic. It was very easy to work with. Just wish I'd got one sooner.
