  • Recommendations for a battery powered rig?

    I'd like to do some busking (never done that before even at the ripe old age of 60 but hey, you only live once). Trouble is I play keys so a piano is pretty much out of the question and although I have seen it done (piano on trolly) I have no way to transport it. However I do have a keytar (Lucina) which is battery powered so I was thinking of using that along with a looper pedal (have to rig a battery pack for it) but PA is the main issue. I know there used to be a thread on here about it but I guess it's long gone now with the new forum. I have been reading about a few different battery powered PA's and it looks like there are several Roland ones. The AC-33 and Roland Cube Street get good reviews but I see there's a new Roland Cube Street EX on the block and there's also the KC-110 kb amp (with other inputs as well).

    The requirements for the PA are going to be pretty input from the keytar (through a looper pedal).
    A Mic
    Maybe an input for backing tracks from an ipod or something.

    I'd also need a battery power pack of some sort to power my looper and vocal effects (I need the effects as I cannot sing to save my life LOL).

    optional - A battery powered mixer maybe maybe but that depends on the mixer inputs.



    I'd like to keep the whole rig down to the size of being able to physically carry it (keytar in shold bag etc) but at worst, nothing bigger than will fit on a small hand cart.

    Suggestions (other than don't do it LOL)?

    Thanks

    You might want to check out the Carvin Stagemate. Self-contained, battery powered 4-channel 100W PA system.
    The 5-channel S400D is an amazing portable sound system with built-in digital effects. Ideal for parties, picnics, club meetings, weddings, church gatherings, etc. It is lightweight and easy to operate. Use it with a keyboard or drum machine or as a DJ-Karaoke system. Battery or AC operation. Made in the USA.

      I guess the other question I forgot to add is 'how much power is enough'? 8 watts, 20, 30, 50, 100? I'm thinking about playing in the street or in a park etc. I want enough power that what you hear is really the pa and not just my natural (and effectless) voice etc but not so much that people complain. Enough so that anyone within 30/50 feet perhaps could hear without it being so loud that people complain. It's hard to judge how loud 8watts or 50 watts is without actually trying it.

        Can't really advise other than to say I have the Roland AC60 which is immense so I assume it's little battery powered brother would be equally as good. However I can say go for it... I used to busk as a student to supplement my living expenses, that was in the days before amplification for street performers. So me and my acoustic basically put me through college, or at least kept me in beer. A year or so ago, I was in the UK (Liverpool) and had just bought a new acoustic guitar and was staying in a city center flat. My missus went out with friends for the afternoon, so on the spur of the moment, I headed out on the street for a couple of hours. The upshot was, I had great fun and made the equivant of about $80. If I lived in an appropriate area I would definitely give it a go more regularly. Cheers Steve

          Wattage ratings are pretty meaningless when it comes to volume. Too many other design factors can affect it (speaker sensitivity, cabinet design, etc.). A 50W amp can be louder than a 100W amp. And keep in mind that you don't have to play at max volume. You can always turn down if it's too loud, but you can't turn up if you've maxed out the amp.

          With keys, I would assume you want some decent low end, which is one reason I think you'd be happy with the StageMate. Have no experience with Roland amps, so can't give you suggestions there.

            This is what I use to power several parts of my ceremony system including a small mackie mixer, ev sxa100 speaker and wireless mic. Not as convenient for busking as one battery powered speaker, but a great tool for $100.

              I know TAH (aka Graeca) swears by his Crate Limo 50...battery is good for 4-6 hours, IIRC, and handles full range including bass.

                I'd considered a pure sine wave inverter to power my existing rig (QSC K10, Beringier mixed etc) s I have a spare marine battery in the garage but even smaller 600 watt xantrex prowatt unit runs $170 or so (who knows if that's enough or not!) and as far as I could figure the current draw at max output on the battery I have would give me about an hour of playing and I'd have to lug a ruddy great battery around as well! Just did not seem to make sense when purpose built battery systems seem to get much more time for the weight!.

                  I've heard that pure sine wave is best, but those marine batteries are very heavy. And the inverters can be expensive. How much you're willing to spend and how much will you make busking are considerations in deciding. How much volume do you need to busk? A synth or elec. piano kind of requires some low end too. You could get 3-4 hours out of a power center like the link above or there's one by Duracell that's 600 watts.

                    I was only considering an inverter because a) I already had a deep cycle battery (regular car battries don't last) and b) I have a decent PA already in the form of the K10 but the best I can find for power consumption on the K10 is 240 whats at 1/8 power. That's 2 amps at 120 volts. If you pro rate that to say 50% that 8 amps at 120 volts (which I doubt but hey, who knows!) which would mean the battery would be putting out 80 amps at 12v (assuming 100% efficiencywhich does not exist) and at that rate the battery I have would alst around 45 minutes. Now I don't think it'd really be that bad but I'm not going to spend good money just to find out!
                    I'm also just playing the keytar since it's portable which can run on batteries for 3 or 4 hours so powering the keys is not an issue, just the pa for the instrument and a mic.
                    Budget wise, I'm looking for cheap, after all I just want to do this to cross it off my bucket list and to have a bit of fun, I'm not looking to make any money from it but I also have to keep expenses down to keep the wife happy!

                    So far that Behringer seems like a good deal although I cannot find anything on it from a user experience point of view other than a few comments on the sweetwater site. On the other hand the Roland Cube Street seems to be pretty popular and well liked and I'm sure that once the EX becomes generally available (it's just come out so not actually in the shops yet) I bet there will be a few used regular Cube Streets for sale so that may be an option.

                      Just looked at the specs for the EX not sure of the price but it looks fab for what you need. Cheers Steve

                        Yeah, that's my preferred DC-powered rig...good battery life, easy to transport, excellent sound.

                          I used to use a Roland Mobile Cube for senior center gigs running a Yamaha keyboard and vocal mic through it. Only 5 watts, but it easily filled a cafeteria-sized room at a decent volume. Has some nice effects, too. I now use the Roland amp in my homemade electronic bagpipes and it is loud enough to compete with "real" bagpipes in an outdoor setting.

                            I've been using a battery-powered rig for years now, and I've powered a pair of Yorkville NX55P's for FOH, an AER Compact 60/2 as a floor-monitor, a Soundcraft EFX-8 mixer, plus a few LED wash-light fixtures for up to 8 hours, with no issues whatsoever.

                            The battery is a 12v/115ah deep-cycle battery that I picked up at Costco for $89. The inverter is a Xantrex 1500w MSW 12vDC-120AC inverter that I bought at a 1/2 price sale ($79. iirc, at Canadian Tire)

                            I've also got a 300w 12vDC-120AC MSW inverter which I use if I only need my Compact 60, the EFX-8, and a few wash-lights.

                            I've never had a lick of trouble with noise. The battery's kinda heavy, but that problem is easily resolved with a compact/telescopic-handle luggage carrier.

                              Read about using a deep-cycle battery like yours...always wondered what it would cost, for powering my PA for outdoor gigs where I'd ordinarily have to use a couple 100' extension cords (one gig required 3!) because the spot chosen for the band.

                              Very much appreciate your info!
