This page is about modifying my Alesis QS6 so that it has an internal power supply. That means I whenever I get a new synth to play with, I take it to bits and see if I can make it work better. Hi! I'm Ben Weaver, and I'm an electronics engineer. (Another bang for the buck from Alesis) The QS6 comes with a. With 61 velocity and aftertouch sensitive keys, 8MB ROM, Serial port interface (PC and MAC), 64 voice polyphony, and the powerful QuadraSynth Plus synth engine, it sure stands out from the under 1,000 synthesizer market. The QS6 is an even more affordable version of the QuadraSynth.It's a "floor slug" type thing with a mains lead coming out of one side, and a low voltage cable coming out the other. Be sure to register your QS synthesizer on the Alesis website,ALESIS QS6 Keyboard AC POWER SUPPLY AC09-25DQS6 QuadraVerb Wedge DMPro S4 QSR and 1622 This auction is for a used (not abused) ALESIS QS6 Keyboard POWER.One of the niggles I have about the QS6 is the external power supply. Ask your music dealer about Alesis Q-Cards. With an Alesis Q-Card ROM expansion, you get 8MB of additional professional-quality samples to add to your palette, in whatever genre of music youre into. And dont forget, like their predecessors, the QS6.2 and QS8.2 are expandable.
Alesis Qs6 Power Supply How To Get AnIt's not very technical, but you will need to do some metalwork (which takes time and patience) and some small bits of soldering and mains wiring. ALESIS QS6 SYNTHESIZER POWER SUPPLY REPLACEMENT ADAPTER AC 9V 2000MA 4 PIN DIN eBaySo natural events took their course, and here I am writing a page on how to get an internal QS6 power supply. You will simply need a plug tip converter from UK to your countries plug type (which we dont provide). This connection is an important safety feature: it keeps the QS6.1&213 s chassis at ground potential, preventing accidental shocks.These power supplies also work in all countries which use 220-240v. The IEC-spec power cable included with your QS6.1 is designed to connect to an outlet with three holes, the third of which &209 the round one &209 is the ground connection. But still, seriously, take care, and don't come running to me saying that you've burned your arm off. I think of it like fire - obviously it's dangerous, but properly controlled then it's quite safe. But if you know what you're doing, and you're confident, then they can be quite safe. And I should point out that obviously mains voltages are a bad thing, and if you prat around with them then you'll die. Get someone else to do it. ![]() The top should then lift off - but be careful as you will need to steer some studs at the front of the synth. There are a number of small screws along the back and down the sides of the synth. First of all, take the top off the synth. A small soldering iron and associated bits.Right - here we go. Nuts, bolts and a cable eyelet for the mains socket. An panel-mounting IEC (aka "Kettle Lead") socket. There are three silver screws (two on the left, one on the right) holding it down, and you'll need to unscrew the five jack socket ring things on the outside. You don't really need to take it off, but I'd rather put it somewhere safe when I attack the rest of the chassis with power tools. You'll need to disconnect the red-socketed ribbon cables from the keyboard, and unplug the aftertouch connector on the left of the main PCB.Finally, unscrew the main PCB from the chassis. Make sure you make a note of which way round the cables go.Now unscrew the keyboard from the synth chassis. I recommend putting the socket on the right hand side of the back panel (looking from the top). The next step is to cut out a hole for the IEC socket. (My chassis is signed by someone famous - but that's another story!)Okay now the fun starts. There's no fuse in the circuit here, so make sure you use an IEC lead with a 3A fuse. When you're done, you should end up with something like this: Remember to drill two 3mm holes at either side of the socket ready for the screws to hold the socket in place. (Rather than the other way round.) Now drill/mill/file/nibble out the metal bits that shouldn't be there. Remember the old adage: Measure three times, cut once. If you want DC then you'll have to rectify it. How much is "too much" power? Well, for example, I wouldn't run another synth from it! And remember it's going to be AC. Be creative, but don't draw off "too much" power because the little transformer will probably keel over and die. For example, you could probably draw off power for driving a set of LEDs which you can use as worklights if you happen to be in a dark area, like on a stage. You might like to think about what you might do with a low voltage AC socket on the back of the synth. If you had an extra external power supply and connected it to the synth and turned it on, then you'd probably get 240V back out of the mains socket we've just added in! That would be bad. Family love taiwan drama"Will you do the modification for me?"No. But please don't contact me asking silly questions like "What's a soldering iron?". I'll try to explain any point of the project in further detail. If you're unsure of any point, then please do get in touch with me. This webpage and its content is © 2006 by Ben Weaver. I'd be really interested to have a look through the schematic for the QS6.The best way of contacting me is through email. Once was enough for me! How to contact meIf you have a go at doing this modification, then I'd love to hear how you get on.I'm also keen to get hold of any technical documents for Alesis synths.
