Originally posted by MyTrunkSlamz quoted-----"There is a point at which you exceed the amount of current that the head unit can supply to feed all those amps (or whatever you are splitting the signal to) and then the signal voltage starts dropping like a rock.If your head unit only has one set of preamp outs, you may be limited to only a few splits. Line Output Converter (Create RCA jack From High-Level Input). The equipment used to effectively split an audio/video signal will differ depending on whether that signal is digital or analog and the desired configuration. Now we move to our 3rd method that is Line Output Converter (LOC). I know some of you will be shocked that I dont know the answer to this. In this method you just splitter cables. The input of the amps should be a stereo input. Hi, I’m Noor Alam, founder of SpeakersMag.com. We will discuss in detail all these methods. The Little Dual allows me to use each amp independently, while giving me the option to play through both amps … What happening is that you're making the Modi drive two loads in parallel. This is of course my experience on a professional concert pa system when i was was an audio engineer. - W A line output converter or LOC is a device that converts the high voltage signal to RCA preamp level signals. The one you find the best can be used to split RCA. You're not "halving" the signal, unless there's some impedance issues going on. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning. 2/ use the tape monitor outputs on one of the amps (if either has them fitted) to the other. The paralleled capacitances of the two cables (and the RF attenuation at the inputs of your amps) will present doubled capacitance and that will draw doubled current charging the capacitance. Can you split 1 USB signal to two devices ? The second wire has a male plug that will be connected to the next amp. Don't use multiple splitters. Jan 13, 2007 New York. You might look at the listed input impedance for amp and sub. In this way, you have got two RCA jacks. Since most modern equipment has input impedances in the mega-ohms, and output impedances in the kilo-ohms you can usually drive several devices from one output. 99. ... (you need two for each stereo pair), some wire, and a project box. I keep seeing all these options out there some from $20 ABY boxes up to $200 for dual … Multiple monitor audio/video configurations are becoming commonplace in modern day digital signage applications.

I do something close now. With the Lehle guitar pedal, one instrument can be routed to two amplifiers simultaneously. Some desktop configurations call for two monitors that will display different images, i.e. I figured I should just try it with a simple splitter at first to see if it works ok. From what I can gather from the answers here and elsewhere, that should be reasonably safe to do. The problem is, when I use a Y splitter to split the subwoofer out to the two subs, I notice a significant degradation in SPL / sound quality. This seems unusual because splitting the signal with Y splitters is a common practice for capturing the video/audio output, and it never has issues sending the signal to both paths.

I have a Jeep Wrangler JK, and have the top down/doors off a lot. Turning now to your impedance concerns, if you were to split the mic signal with a simple Y-cord the mic would indeed ‘see’ the two input destinations effectively in parallel with each other, and that will result in the effective load for the microphone being reduced below the impedance of either. What are the drawbacks of splitting a stereo signal into two mono amps? the DSP has two inputs and four outputs. A line output converter can help you increase the number of RCA jacks to connect multiple amps. Doing a parallel split can result in an impedance drop. Sweetwater Sound The main factors that you need to consider when you wire in two or more amps are how you will deal with the power cable, grounding each amp, and whether or not the remote turn-on signal from your head unit is strong enough to split between multiple amps.
