Great for live IEM's
ScottN, 27.01.2016
I bought this with hopes of finally being able to use stereo aux mixes at my live shows. After using a mono wireless system I can gladly say that the improvements when using stereo are second to none. It is like having a mixed studio track sent to you on stage. The clarity in sound is superb! The volume is very sufficient without clipping. If ever you do start to clip to loud a LED indicator will light up red prompting you to turn down your aux output level.

This unit is covered in a rubbery plastic which not only gives it a nice feel, but also gives a professional and clean look when in the audience's view. The metal clip is solid and looks like it will last the high demands of being clipped on and off a belt for many gigs to come.

I have never experienced such high quality sound in a monitor mix.

As a keyboard player I have always felt slightly claustrophobic and enclosed when using other systems in a mono setup. Thankfully now, my keyboards are stereo and backing vocals have been panned along with the sax and guitar. I often forget that I'm using IEM because the feeling of being isolated is eliminated.

I would have liked this system to include a power supply but looking at the price it is easy to understand they had to cut costs somewhere. I recommend using a 9v rechargeable battery to save you running costs.

If you are somebody who would like a high quality monitor mix in your ears during a live gig I would urge you to try the HPA 1!

Excellent high quality amp which I can't live without
I've had this a few months now and it works perfectly and has transformed my rock singing and is saving my ears - no more ringing and I'm better in tune. It's really hard to fault and I won't sing now without it. The amplifier is very low noise and has excellent sound quality. It can go plenty loud enough for any occasion without getting harsh. The limiter is useful preventing drums and other noises in the mic from being unpleasant. I've seen it operating quite a lot. The box is quite big for this type of thing but is very strong and has a nice durable finish. The size isn't a problem if you wear it behind you as most people do. There is a feature where you can mix left and right into mono and adjust the mix while you are wearing it. Although this works well having a mic cable and 2 more XLR leads attached to you is a step too far unless you are very still. I use a mix from the desk and once it's set it's generally close enough for the whole gig. If you are thinking about in-ear monitoring this is a good way. To get this quality with wireless would be many times the cost. It's very important to use some good ergonomic noise isolating headphones though, something like Shure SE215.
