DJ mixer problem? Answered

I have recently purchased a Soundlab dsm5....I have minimal RCA cable at the moment so i have done this -> I have connected my ipod to the mic jack with a 3.5mm to 1/4 inch adaptor..... then from that i have connected a RCA cable to 3.5mm mono adaptor (orginally for a camcorder so it has a video RCA as well)  from the AMP channel on the mixer to the AMP......  My problem is ....is that the Music plays but has a really bad quality? ....my amp is not bad quality, as i have done played music with it with no problem and the mixer and the amp are both sound lab....It might be I shouldnt connect the ipod to the mic but to line one or line 2 (inputs) to get more quality ....

Custom audio mixer box

I need a device to do the following. One input source for stereo (ipod), one input source for mic. Two stereo outputs to headphones (ipod earbuds). The device would mix the input audio (with a volume control for the mic input) before sending it to both outputs. Is this something that can be bought? If not, anyone interested in making one?

Passive mixers, I don't undertand why the resistor/capacitor

Hi, when I was young, our teacher show us a passive mixer, each input had only one green capacitor in series for each input, it was not electrolytic but ceramic or polyester, it sounded so good for just being there 1 simple component per channel. Now taking a look at google, can see that the most passive mixers, uses resistors to isolate sources, with values since 10k to even 100K. Other schematics shows a resistor and capacitor in series (see image below) what does that capacitor? and why some schematics only has a simple resistor? is it easy to calculate its ohm value?. Is it better using this configuration supposing that the source is weak (coming from cellphone 3.5 mini jack or RCA) and this mixer targets the signals to a pre amp? So I need to from weak sources like iphone, dvd, any RCA output, etc... anybody know whats the best to use in this case? Thanks so much. Should I put a resistor as minimum as possible? I undertstand that a resistor there, in the input, will reduce the volume input, and I dont want to do that, so can I simple connect everything direct? or the resistor isolates the inputs, otherwise it will sound ugly? I am very confused, why the resistor? why I have seen resistors from some ohms to 2km and even a lot more, 50k, 100k. I want to mix two weak sources, as a signal coming from a walkman and cd player, or cell phone, etc, so whats the law for not reduce signal intensity and mix everything well? all channels will come in into a pre amp IC.

Ideas for live sound effects mixer-player?

Hi, I'm trying to build a remote device whereby I can play multiple recorded sounds over my stereo speaker system, sometimes simultaneously. Imagine as a Halloween project, for example, I would want the sound of a wind storm going continuously, and then occasionally hit a button or slider with another sound, like wolves howling, footsteps, a creaky gate, etc. Ideally I could play as many sounds as I wanted at a time on discrete channels, and each would be mixable... all that in as small a mechanism as possible. Any thoughts/ideas/referrals?  Does this sound like a job for an arduino? Thanks for reading!

Active mixer and 180 degrees out of phase question? Answered

Hello , i want to make a simple active mixer to place in front of the power amp. I read some documents about active op-amp mixer.And they said : "Any signal entering the inverting input of the op-amp will appear at the output but it will be 180 degrees out of phase.If the output of the first op-amp were recombined with one of the other signals at a later stage it would cancel out rather than mix. So we have to re-invert the phase with yet another op-amp." and the schematic should like figure 1 to re-invert the signal . But if i use the the mixer to direct feed input of power amp , can i use the schematic like figure 2(w/o re-invert the signal) ??? Thanks in advance! Sorry for my bad English!

RGB LED Mixer Schematic

Hi, for the past couple of months, I have been searching for a RGB LED mood light controller, but so far, all of them require a PIC(Programmable Integrated Circuit). The problem with this is that The PIC, the PIC Programmer, and the IDE for some reason wont work together(even though they are all from the same company). So recently, I thought that it would be easier to just make a color mixer, that controls each of the RGB channels individually with a potentiometer assigned to each. But, I can't find a simple one. So I made my own, but I would like to ask the Instructables community if they think it will work. Thanks ahead of time :) Here is the schematic:

What made the motor lose it's mojo?  Is there a way for me to make it strong again?

Feeding samick guitar signal and mp3 into guitar input of samick amplifier.?

Hi, My wife is an amateur musician she has a samick amp with two inputs mic, and guitar, we are trying to input a mix of sounds into the guitar input. I have tried a connection from the headphone socket of mp3 player, in a double adaptor config with guitar, this is not ideal, due to the  unbalanced signals, and there is a loud hum.  What can I do short of buying another amp. Also I don't know what the impedances are but suspect the mp3 player is 8-16, and the amp input much higher. I am wondering whether a simple mixer might help, but I don't know how impedance might affect this, or whether it would actually work. Thanks for any comment

Outdoor listening installations

Would appreciate some advice on this project.  I'm putting together a proposal for a series of outdoor sound installations in a nature park.  a couple of the installations will be places where you can plug in headphones to listen to certain sounds captured live from a microphone in an interesting place- for example a hydrophone in a pond.  The plan is that the mic will be hooked up to 3.5 jack sockets and listerners will be able to plug in their own headphones.  Now obviously there needs to be some amplification because the mic signal level will be far too quiet to hear on headphones. I need a power amp that will be powered through a solar panel.  My question is, shall I just use a headphone amp, like the Behringer ha400 or make my own power amp circuit? I need to be able to make everything sturdy and fit into a weather proof junction box to protect it from the elements. I have done some experiments with an LM386 power amp module but there was so much background noise and it didn't pick up the mic level at all (may have been a problem with the mic I was using,it was a crappy little lapel mic.- I did get a signal from a piezo disc but it was again really crackly and noisy.)  If it is best to build a circuit with a power amp module, could people make suggestions of ones that will sound good and clean, and work with stereo headphones.  Thanks a lot Ash

Simplest way to combine a mono and a stereo source to play through a set of stereo headphones?

Ok, what I am specifically wanting to doing is make the Xbox voice chat (mono) and the game audio (stereo) come out through the same set of headphones. I quickly found out that I couldn't just wire them directly without turning the game audio to mono (not good for online multiplayer). I found a discussion about using an "opamp" and taking the mono signal and feeding it into the right channel then take the opamp output and feeding that back into the left channel to get a "stereo" output. Unfortunetly, I got as many details from that as I just gave here. Can anyone explain how and what parts it would take to do this? I also got the impression it might be passive, and no batteries would be a plus. Preferably, I would like to be able to get the stuff at Radioshack, and ideally, I would want to try and stuff the parts inside the over-the-ear cup style headphones directly.

Arduino Uno Synth project - Audio output questions

Hi! I am developing a synth/sampler project based on the Arduino Uno r3. This is my first electronics project ever and because of that reason I have some questions which I can't find a definite answer for on internet. The synth has two function. It has a tone generator using the ToneAC library. With code I have mimicked LFO and VCO functions, using potmeters I can adjust the frequency and LFO speed realtime. The other function is that I can trigger samples stored on a SD card using the TMRpcm library. The device will be used in nightclubs on high end soundsystems and PA. I am afraid I will damage the equipment with my device because I do not send a pure audio (AC?) signal. Currently the flow is like this: PWM output (pin 9, 10) -> voltage divider to 2.5v -> RC Low Pass Filter 15Khz -> LM386 amp with volume control -> mono jack output -> mixing desk -> amplifier -> speakers (the TMRpcm and ToneAC library share the same pin (9), I have fixed this by disabling the TMRpcm when the ToneAC is playing and vice versa. The mono jack is wired as follow. pin 9 goes to plus side of mono jack output, pin 10 to negative side. The TMRpcm pin 9 also needs to go to plus side of mono jack output, and mono jack negative needs to go to ground. Because I disable the ToneAC at that time I consider port 10 grounded because it not generating any sound so there is no signal/voltage running out of it, aka the IO pin is set to LOW) I am hoping that using the voltage divider I am within range of the Audio Line levels of a default mixers Line-IN (like Pioneer, Behringer, etc). The RC Low Pass Filter is used to filter of inaudible frequencies and clean up the sound a bit, the LM386 audio amp is used to amplify the signal and (hopefully) make it a real audio signal. The lowest frequency you can play with the synth is 100hz and the highest frequency is 3100hz. Because I lack a lot of knowledge in this field and because I do not own a oscilloscoop I can't say for sure if my output signal is harmful for the equipment and was hoping to get some guidance on my project on this forum.
