My current karaoke system includes an RMX2450 Amplifier, MG12/4 Yamaha mixer, CDN25+G Numark CD+G player all rack mounted in a SKG Case. My pair of S115V Yamaha speakers are connected to the amp in Bridged Mono. This set up has plenty of punch and sounds fantastic in the bars and reception halls that I play in. My problem is this. I have hired a KJ/DJ to do some gigs for me and my Rack mounted system is too heavy for her to carry by herself. Heck, it takes quite a bit of exertion for me to lift it myself. Can you help me put together a system with the amount of power that I am used to in my current rig, but could easily be set up and torn down by my new DJ? Another restriction is $$$$, I am looking at spending less than $2000. I really like the Yamaha products and was thinking about building this second system around another pair of S115V's so that both systems could be interchangeable... Thanx in advance for your help! ---nick |

Personally, I don't like the mixer/amp combos, because I like the flexibility of separate components, but this is certainly one situation where I would recommend one. Since you like Yamaha, check out their EMX series (one example: http://www.musiciansfriend.com/product/ ... sku=630607 ). There are less expensive models, but that should give you an idea. That would put all your mixer and amp functionality in one console, and then build a second console for CDG player, video switching, additional CD players and such. If you use the plastic road cases they will be lighter than a wooden one, but cost a little more. setup with a system like that is very easy, and tends to be lighter thna using separate components. |

Better yet, this is more what I had in mind: http://www.samedaymusic.com/product--YAMEMX512SC |

If I'm reading this right, looks like the EMX512 and the EMX 5016 would both put 500 Watts Power to each speaker, right? So looks like the 512 would be the better deal and has enough to satisfy the 500watt minimum on the S115V. Is the 500 watt per speaker enough for medium karaoke/DJ venues? Has anyone here at the forum ever used the EMX512? Thanx for your help Meep... looks like you've pointed me in the right direction. |

Watts do not translate directly into the sound pressure (how loud) the speaker will generate. The design of the speaker has a great deal to do with it. For example the S115V is designed for a lot of thump so it reproduces the sound of a floor tom fairly well and is good for hip hop and head banging music in general. On the other and it is not great for contrabasoons, and vocals can be a little muddy (only if you're listening for it) in a two speaker system because the 15" is going to have part of the vocals and the horn the other and the 15" does not respond as quickly. A minimum power rating of 500 watts? I don't think so. The S115V has a program rating of 500 watts, which means under normal circumstances that is as hard as it should be pushed. The peak rating is how much power it will stand without blowing up but only for an instant. I wouldn't think the weight of a system should be a problem for a female KJ. All she has to do is smile. |

I use the EMX5000 Yamaha Powered mixer for portability, weighs in at 33lbs and has a carrying handle. Dual effects processor is really nice for running separate efx for vocals and music. Guitar center sells this unit with the S115V's in a package deal. Price on the EMX5000 runs $729 Be sure to purchase a protective carry bag for it for like $60 |

Thanx for your help Meep... looks like you've pointed me in the right direction. Glad to help. I haven't used the current model line at all, but have used older products in that line over the years, filling in for people who used them. The EMX640 (similar to the 512, but less powerful) was quite popular among local KJs in this area several years ago. It was 200 watts per channel if I remember correctly, and I saw lots of them used to do medium sized gigs with no real problems. One of these KJs was known for his attitude that louder is better and he was frequently asked to turn it down. This was with speakers similar to the S115V. |

Thanx for your help Meep... looks like you've pointed me in the right direction. DOn't let that 500 watts per channel fool you. Your current RMX2450 pushes 500 watts per channel into 8 ohms - bridged 2400 watts into 4 ohms - which is what both your current speakers would be connected to the same bridges output. This amp is actually a little more powerful (in bridge mode) than your speakers require. Your speakers when connected together would yield a 4 ohm load which would also raise their combined power handling to 1000 watts program (the rating you want your amp) @ 4 ohms. The EMX 500 series is only rated at 380 watts per channel into 8 ohms - less than your speakers want in a dual mono or stereo mode. These amps aren't bridgeable so the most you'll get into your 4 ohm load if you run both on a single channel is 500 watts max into 4 ohms - which is less than your speakers combined load/power rating requires. That 2450 is a great amp, but it is also a heavy one - almost 45 pouns by itself. Have you considered some of the lightweight amps. Crown makes XTI2000 equivalent amp to your current QSC, but only weighs 17 pounds. http://www.americanmusical.com/item--i-CRO-XTI2000.html This may be a better alternative for you while still keeping the power you are used to & lightening the load considerably. And being it's a Crown, it has the 3 year NO FAULT warranty, so even if you blow your amp, you can get it fixed. |
