kwyn Posted September 5, 2021 Share Posted September 5, 2021 Please recommend one. The one I saw on sweet water got bad reviews. Hope it"s the power supply. It just won"t turn on. At a gig right now and mixing through my zlx12 which is also my powered monitor. Not ideal Quote Link to comment Share on other sites More sharing options...
ElmerJFudd Posted September 5, 2021 Share Posted September 5, 2021 I don"t have mine with me at the moment. You can reach out to Radial for a replacement but that doesn"t help you today. If an owner can share the voltage and ampere rating, that would help dig up a generic replacement. Quote Yamaha CP88, Casio PX-560 Link to comment Share on other sites More sharing options...
timwat Posted September 5, 2021 Share Posted September 5, 2021 Spec in the owner's manual says 260mA, 15VDC, center pin positive. I don't know where the best place to get third party power supplies is these days. Would the one for the Shure wireless head units work? It's rated at 15VDC, 600mA and only $21?

ElmerJFudd Posted September 5, 2021 Share Posted September 5, 2021 Amazon I guess, but since you can"t walk in the shop with your key largo to make sure the connector fits as well as delivers the right juice rating, sigh.

mate stubb Posted September 5, 2021 Share Posted September 5, 2021 With a high fidelity unit like the KR, I would be concerned moreso than with some other devices of the quality and cleanness of the power supply. By all means find an emergency backup, but consider an OEM replacement when you have the time. Quote Moe --- Link to comment Share on other sites More sharing options...
kwyn Posted September 5, 2021 Author Share Posted September 5, 2021 Just ordered the radial one from sweetwater. Hope it is better than the customer reviews say. Really sucked trying to mix through my pa speaker. OT question, when I mix through the pa speaker, does the master volume for the zlx12 also raise the volume on the line-out of the zlx12 going into the foh board?

I don"t have the zlx12, however I would imagine raising the volume of the amp would not change the line out"s volume. That said, if there is also an input gain setting on the zlx12 - that would increase volume at the line out most likely. But test this behavior either way.

kwyn Posted September 5, 2021 Author Share Posted September 5, 2021 This is why I refuse to gig with wall warts It"s my piece of gear with one, and my only piece of gear to ever fail. You would think a premium product like the key largo would have a built in power supply. Oh well. Quote Link to comment Share on other sites More sharing options...
BEMcCut Posted September 5, 2021 Share Posted September 5, 2021 I have a Behringer Micromix MX400 Line Mixer in my gig bag as a backup. Not on par with the Key Largo but better than nothing if you get stuck. Quote Link to comment Share on other sites More sharing options...
ElmerJFudd Posted September 5, 2021 Share Posted September 5, 2021 This is why I refuse to gig with wall warts It"s a valid reason. It"s hard not to appreciate my PX-560 during load in, changing rooms and load out. So easy to drag around. But dangit, I left the wall wart the other night at the venue. Even after the idiot check. Takes just as long to order the manufacturer"s as it does for me to find and order a match. Quote Yamaha CP88, Casio PX-560 Link to comment Share on other sites More sharing options...
mynameisdanno Posted September 6, 2021 Share Posted September 6, 2021 I wanted a line-lump style PSU that I could mount under a small pedalboard so the DC connecter could remain permanently attached to the Key Largo. I ordered a "Zozo" brand 36W selectable voltage universal PSU on Amazon. I set it to 15V and gaff taped it to the bottom of a small pedalboard, along with another one at 12V to run the Mini-Vent. I gaff taped them to the bottom of a Pedaltrain Nano and they've both been running happily for about five years now. I keep the official Radial PSU in my bag in case of failure. Unfortunately it's discontinued. Amazon and other outlets appear to have a very similar unit available under the "Belker" brand as a 45W unit that also goes up to 15V. They sell both a wall wart and a line lump style. Can't personally vouch for the "Belker" as far as including the correct size tip, etc., but it looks almost identical to the one I have. Probably the same design rebranded. Quote Link to comment Share on other sites More sharing options...

mynameisdanno Posted September 6, 2021 Share Posted September 6, 2021 Nice find. So you can dial in voltage and it has a variety of connectors. How does it handle polarity and amps? For amperage, the Key Largo will draw whatever it needs, and as long as the power supply is rated for at least that current draw at that voltage, you're good. The stock Radial PSU supplies up to 260mA at 15V. The Belker unit says it supplies up to 2000mA at 15V, so it's got *plenty* of headroom for the job. Same with the old Zozo. Polarity is correct for the Key Largo (center positive) but if you have center negative devices you need to flip for, they do sell a short cable to reverse polarity.

Stokely Posted September 6, 2021 Share Posted September 6, 2021 At one point I had a rig with no wall warts. So great to be able to use any standard power cable, and buy them for the exact length you want. Just have one extra of decent length and you are covered (not that I've ever had one of those go bad.) Besides them being so specific to each piece of gear, the worst part about wall warts are the flimsy tiny cords that tangle and make it more work to run properly (I'm considering shrink wrapping a couple of mine or doing something to give them a bit of "heft". Having a wall wart is definitely a "con" when considering gear. Not enough of one to be a show-stopper (as my current rig shows, I have three between my MODX, Key Largo and Behringer monitor mixer). The line lump kind are definitely better than the plug on the wart, interested in that one talked about above. Quote Link to comment Share on other sites More sharing options...

timwat Posted September 10, 2021 Share Posted September 10, 2021 I just ordered two of those Belker line lump supplies from Amazon (one for my KL, one for my Lester K). Supposed to arrive Monday, I'll update once I see if they work adequately. I was due to reconfigure my pedalboard a little bit, this provided a good kick in the pants to do some fiddling. Quote ..

Docbop Posted September 10, 2021 Share Posted September 10, 2021 There are lots of makers of power supplies for guitar pedal boards so one AC powered PS to feed multiple pedals. Keyboardist should be hounding these companies to make a keyboard version with the voltages they need. Quote Link to comment Share on other sites More sharing options...
timwat Posted September 10, 2021 Share Posted September 10, 2021 The challenge (at least for me) is I need 15v center positive, as well as 9.6v center negative. Those with a Ventilator will need 12v. Most of the guitar pedal power solutions I've seen have an abundance of 9v outputs, with a stray 12v or 18v. Maybe I just don't know enough about guitar pedal solutions. Quote ..

AWkeys Posted September 11, 2021 Share Posted September 11, 2021 Yep, I was building a pedal board, and trying to find one power brick to do everything I needed was impossible. I needed to power an EH Holy Grail Nano, a Lounsberry Tall & Fat, a Ventilator II and my Key Largo. I ended up making the pedal board big enough to hold a power strip. While it's larger than I was hoping, I have no worries with power and never need to disconnect the Key Largo power supply (or others). BTW, in my researching this issue, I found on the Radial website that the Key Largo can be powered with an 18v supply, but that it will lose about a year of its projected life span - something like 18 vs. 19 years. Gotta love Radial for that info! Quote Link to comment Share on other sites More sharing options...
timwat Posted October 2, 2021 Share Posted October 2, 2021 Just to bring this full circle: I bought two of those Belker replacements from Amazon. They work very well. One for the Key Largo, one for the Lester K. Setting the voltage is simple. Had to make sure I bought the little polarity switcher cable for the EH Lester K (it wants pin negative). The line lump bricks are small and easy to velcro to the strips I already have on the pedal board. They're also black matte finish so they easily blend into the pedal board visually. They come with a variety of interchangeable pins of different size (including micro USB and LED light, if you have those kinds of needs). The only niggle is that the pin that fits the two pedals is a little longer than the pin that comes with the manufacturer's included power supplies - so it doesn't plug in flush with the back of the pedals. No great shakes for me (as it's a stationary install and the entire board loads into it's own ATA case), but be warned. Other than that, it works great and has cleaned up the pedal board. End of report. Quote .. Link to comment Share on other sites More sharing options...
Stephen S Posted October 2, 2021 Share Posted October 2, 2021 I use the Eventide Powermax for my pedalboard. Lightweight, high current and very flexible. A bit spendy but it powers my Key Largo and other stuff without issue.

Stokely Posted October 2, 2021 Share Posted October 2, 2021 In hopes of preserving mine, and the one for my Behringer monitor mixer, I have made a "pedalboard" (name applied loosely) with both plugged into a two-pronged power cord...both stay plugged into their units and everything is velcroed in place to the board. Eventually I'd like to make or buy something a bit more elegant. This way the only thing that ever gets plugged power-wise is that power cord and nothing will be putting any stress on the weeny tiny cables and connections. I got the idea from some of you on here, it's pretty ghetto so far. Ultimately I might want to make or buy something a bit nicer but I'm still in "proof of concept" stages. I hate wall warts! When I'm 98 years gold grumbling in some home I'll be grumbling about wall warts. Quote Link to comment Share on other sites More sharing options...
