QTX , QR12PA: Powerful Portable PA with 2 Wireless Handheld Microphones, Easy Mobility Trolley Handle and Wheels, Extended Battery Life & Enhanced Audio Control

I only say "nearly" because if I said it's perfect it would imply it could absolutely not be improved. And it can... but it's pretty nearly there! Considering the low price... it's a bargain!I have used it for about 3-4 weeks now. I'm very happy with it.This thing has a lot of functions. I don't need most of them, so perhaps it may not perform as well as you want it to, if your requirements are not the same as mine.I wanted an amplifier for my electric bass, so that I could use it on the street, busking with my band. I wanted something reasonably powerful (bass needs power to be heard), and portable... and the battery should last a reasonable amount of time. They claim 8h on a battery charge... I cannot say, but it definitely does >3h without any issues whatsoever.The band is comprised of 3 guitarists playing electric guitar through two Roland MiniCubes and a Vox Mini. Then we have a trumpet and a saxophone player (unamplified), and a drummer, who brings assorted drummy bits. He likes a cajon, but the cajon is not loud enough by itself.In this situation, on the street, the QR10PA has plenty of power. I rarely turn the volume up past 11 o'clock (if you imagine the dial of a clock on the volume knob). We used it last night indoors, same set up, but in a small bar. My volume knob was a little lower there. So I can be a lot louder if I wanted to.It has a basic 2-band EQ: bass and treble. It's ok. I started using it with my MusicMan Stingray, which as an onboard 3-band EQ module with semi-parametric mids (John East MMSR preamp), so the QR10PA's EQ was irrelevant. After the first couple of evenings I took to using a Squier Precision (Mike Dirnt model), because it's light, comfortable, inexpensive, and sounds good... and I feel I can be a bit more carefree with it on the street. This bass only has a basic passive tone control, so I use the QR10PA's EQ more. However, I now use a separate EQ pedal so that I can better adjust the sound. I use a Zoom MS-60B running on batteries, as it gives me both a tuner and EQ at once (and many other things if I wanted to). Generally the parametric EQ (two band) is perfect to adjust the sound to the acoustics of where we are playing and to fit between the guitars and percussions, but a graphic EQ would be fine too.There is a clear hiss noise coming from this amp when you use it at home at low volumes. It is not noticeable whatsoever on the street or in the bar.Some of the extra functions can be interesting and I have tried some.You can plug another instrument or a mic in a second input. However, there is only one volume. This seriously reduces its usefulness. We tried to put a microphone on our drummer's cajon and run it through the QR10PA, but we needed to carefully adjust the distance of teh mic to the cajon...It would work best if one of the two (my bass or the mic) were ran through an FX pedal, such as an EQ pedal, as that provides a separate volume control for it. At the time I was not using an EQ pedal yet...You can play music stored in a USB stick. I tried it. It works very well. The controls are very basic and not the best to navigate through the songlist, but it's functional. This has a separate volume control. I have never tried the included remote control.I have not tried the radio either, or the SD card slot.The QR10PA comes with a wireless mic. It works. But the sound is not great (what do you expect? :) I don't use it and I am not likely to use it, but I am considering adapting it to use it with a better microphone... we will see. Still, not necesary for me.It has tiny wheels and an extendable handle. I don't use that. It's light and I just carry it with my hand. I have just now found a cheap travel bag with a rigid bottom and better wheels and extendable handle. I put a layer of foam inside and ise it to carry the QR10PA and keep my jacket or whatever.I think it's a great solution for me: I can play my electric bass on the street and do so for hours. It does not sound as good as my usual rig does, but it's decent for street performances.I was not quite sure it would be powerful enough, but it is more than adequate. I don't imagine ever pushing it hard.The controls are all on the back, which is a bit uncomfortable, compared to other units that have the controls on the top. However, this means the controls are more protected from the elements and I get to place a pedal on the top instead. It works for me. It's not rain-proof, of course, but because of the design, it is unlikely to get damage unless you choose to continue using it under the pouring rain.The day it breaks... I'll get another.

This is some machine! The first one ordered didn't work when it arrived but this company made it less painful with their proffesional way of dealing with the return which was complicated by the fact it was Easter Weekend and the now urgent need for me to have a replacement. Although I was reassured that the return and replacement would happen within the time I needed, I couldn't risk not having the PA/mic for an event which was looming. Took the risk and put another order on my credit card. This one arrived on the final estimated delivery date which was the day before I needed it and I received the refund for the returned one on the same day. Phew! I was reasured by the company at each contact with them. Now for the machine - it does what it says in the information. I teach dance in a large hall - now everyone hears me loud and clear. Even if I use a low voice it comes over clear and crisp. Just tweak the setting on the echo and leave it there. It is so easy to set up - even I can do in in a couple of minutes. This is a solid and hefty bit of kit but no problem to move as it is on wheels. I'm so glad that I wasn't put off by the first one not working. Daft thing to say but I'm less tired after a teaching session now I don't have to fight to be heard! Our big event went well and the world renowned Scottish dance tutor who led the workshop was the first to use the mic. Nearly six years down the line - this machine is the greatest! I have added a frequency compatible headset to my kit and this works well. I've learned to tweak the volume etc to get best results - it just takes time. Due to my own preference, I have not used the SD or USB facility much but it is easy to use with clear results.

This item has been purchased for the local WI branch, to meet the need for an easy-to-use, portable PA system for use by visiting speakers, for larger meetings, and so on.It comes with two handheld VHF radio microphones, on frequencies 174.1 and MHz and 175MHz (see below). The mics are plastic bodied, with a metal mesh covered foam windshield. They have a two position switch, OFF-MUTE-ON, and despite being low cost items they work well and are easy to use. They are very directional and need to be 'aimed' at the presenter's mouth; the upside of this is that they are not prone to feedback howl even when the presenter is in front of the PA.Radio mics are usually used with a separate receiver that is plugged into the mixer/amplifier. The QR12PA has the receiver built in, with controls on the back of the unit. The receiver has its own power switch and separate volume controls for each mic in use. (the main unit volume control does not govern the volume from the radio mic channels) . The built in receiver handles two mics, on 174.1/175.0 MHz, so any additional VHF mics you plan to use with this unit need to be on one of these frequencies. I have also bought a pair of QTX 'neckband' VHF mics (order one of each frequency if you want them, items 178.851 and 178.852) and they work fine.There are 2 separate 1/4" jack inputs for a lead microphone, or a guitar for example. There are also 3.5mm and phono inputs for other sources (such as a phone or MP3 player for music) and the built in MP3 player has a USB and a SC card slot. There is also a pair of phono output sockets for the whole mix.There is an echo function that will operate on the radio mic inputs, and presumably on the lead mic inputs if used.There is also a VCV switch, which will partially mute any music being played when speaking into a mic. This does NOT operate on the radio mic source.The manual, which covers the QR12PA and the QR15PA, refers to an FM tuner - the QR12PA does not appear to have one.The unit contains its own battery, which was at least partly charged on arrival, and it worked right out of the box before being plugged in. There is a detachable 'kettle' lead for the mains. There is no obvious way to change the battery, and no reference in the instructions which counsel the user not to open the unit. I believe it is a lead-acid battery that could probably be replaced by a competent person if necessary, and I'm pretty sure that one reviewer mentioned having done that. For what it's worth, my experience of larger lead-acid batteries in boats, caravans etc. is that they last a long time if they are not repeatedly run flat, or left flat, so whilst the battery is claimed to give up to 8 hours operation, I would suggest using it for no more than 3 or 4 without recharging if you want it to last well.This is a fairly heavy item (the spec says it's14Kg,) if you need to lift it on to a stand or even in and out of a car - fit people should have no problem, but it could be awkward for a frailer/weaker person. Just moving it around is helped by the extending handle and wheels.There is a moulded 35mm socket on the base. I'd recommend getting it off the floor, even if it is just put on a side table - it sounds much better.Regarding the sound, it is not hifi, but it is capable of decent volume and with the aid of the tone controls sounds perfectly acceptable and loud enough for a small hall, though not of course for a disco as you could probably still hear yourself speak....Reliability I can't yet speak for, as I have just set up and tested the items, but so far, so good and I am happy with the choice.
