This model has been designed as the ultimate portable PA system for professional use, with huge power and sound quality. You can very easily travel with it, and it has been designed and built to conform to the CAA regulations of approved aircraft hand luggage, however you should always check with your airline as regulations can change. It differs from the Mk4 version in that it is smaller and lighter which makes it more suitable for those people who need the smallest and lightest PA possible that will provide huge high quality sound.

These systems are quite simply jaw droppingly impressive for their size and weight. Whatever small PA systems you have heard before they will not compare to this, and many mains powered, large and expensive systems can be put to shame. This sound quality has only been possible with many years of research and design, in conjunction with great electronic engineering knowledge and skilled craftsmanship – you will not find anything similar anywhere on sale today. And as always this system has been entirely hand built with very high quality components sourced from all over the world.

At the heart of the PA's is a ‘Class T’ amplifier chip (sometimes called digital although it isn’t really) made by a company called Tripath. Tripath are no longer in existence, but before they disappeared they designed and patented a range of amplifier chips that many small audiophile manufactures have used for various applications - Google them. Panasonic used the same amplifier chip in a range of car stereos which broke the world record for the highest power output from a standard production car stereo. Wattage figures are almost meaningless as it depends on what you do with the power, what it costs to create it in the first place, how distorted the sound is, and are the figures even accurate ! (Wattage figures are notoriously lied about, as well as being measured at RMS and peak levels) …however this system has been measured at 80 Watts RMS at ‹ 1% distortion, and calculated at a maximum of 125 Watts in standard configuration. (The Chip is capable of producing 400 Watts in other custom configurations.) It should be enough to say it is very loud and louder than you would think possible from such small boxes.

I just wanted to say how delighted I am so far with your sound system, it's so easy to get a great sound that's loud enough for all the outdoor gigs I've played. Every performer who has heard it has asked me where I got it, I hope you do well mate, they're great.

Thanks so much for your brilliant after care service and also creating such brilliant kit - Your sound systems are so vital to the grannies.

Martin, Granny Turismo (Street & festival performers)


PA is kicking up a beauty.

Jon Hicks (Performance artist)

I started to play the Stuff & Things system in the Belfast Circus School and was besieged by street performers interested in how such a great sound could come from such a small system. Extensive testing over the next two days only served to reinforce their interest. I have never seen such enthusiasm for a sound system in twenty years in the business. This system is going to be the standard for the Festival of Fools – easy to transport, easy to operate and fantastic sound.

Will Chamberlain (Director, Festival of Fools)


Thank you Nick! Perfect, we went to the music shop and the guy of the shop freak out, and he said that you are a genius, he loved the sound of them...jejejee...So thanks again and congratulations for your work, have a good time!

Shyra & Lipo (Musicians)


IT'S BRILLIANT! thank you thank you thank you thank you! heavenly sound and easy to use, stop it!

Amy Saunders - Miss Behave (Performance artist)


Many thanks, the amplifier (2.5.) Is great. For seven years I always had problems with the sound. Since this year no more thank you.

    Specifications :

  • Amplifier : T-Class (audiophile sound quality)
  • Speakers : 2x Infinity 6502ix (2 way, 3 Ohm)
  • Sensitivity (2.83V, 1m) : 93dB
  • Battery : 14.8v Li-Ion rechargeable
  • Size (approx ) : 20cm x 18cm x 10cm
  • Weight Stuffed : 2.3 Kg / 5.1 lbs
  • Weight Thing : 1.6 Kg / 3.5 lbs (+cable)
  • Power Output RMS @ ‹1% distortion : 80 Watts (total for both channels)
  • Max power output (saturated square wave) : 125 Watts (total for both channels)
  • Battery life in Normal use : 3~6 hours *
  • Recharge Cycles : 500~800 (after which battery capacity will be at approx 75%) *
  • Full recharge time (approx) : 5 hours
  • Fuse : 5A slow blow


*Normal use is deemed as being used to amplify constant Rock / Pop music played at high volume without any sound clipping / distortion from excessive volume, and with a fully charged battery. This time will vary considerably depending upon the volume and type of use.

*Battery energy capacity slowly reduces over time according to many factors. After 500~800 charge / discharge cycles, the expected battery capacity will be 75% of original capacity. New batteries can be easily installed if and when necessary.



There is only one input as standard (designed to be connected to the headphone socket of an iPod / mini-disc / MP3 etc, or via a line-out socket, or connected to a radio microphone set). More inputs can be added when ordered, or if you need a small mixer for multiple inputs, places like Ebay have some cheap ones. For higher quality, more expensive, and slightly larger battery powered or mains powered mixers try Behringer mixers - www.behringer.com or look for a USB powered mixer and power it from the PA itself.

The main active speaker unit ‘Stuffed’ can be bought on its own and can be used either with or without the additional passive speaker ‘Thing’ attached. The Thing unit is just a speaker – it does not contain an amplifier or battery.

Since the amplifier chip is a high frequency switching mode one, it emits some radio interference which can interfere with AM, FM, LW, SW radio signals in close proximity – for this reason you may not be able to amplify these signals, But radio microphones are not affected and can be used with excellent results.

The units are available in custom formats – amplifier only; amplifier with battery and no speaker; extra outputs etc, but generally the best and most versatile option has two speaker boxes - one plugs into the other so you can have the option of a one or two speaker set up – this is a ‘Stuffed and Thing’.

And remember…. you are paying for what is there, as well as for what isn’t !
