    Hey guys I came here because I really need help on what must be incredibly simple for you guys but frustratingly hard for me!
    Heres the deal I have two 800w active speakers with the backs that look like this:

    I have this sound mixer the Alto Professional ZMX862 which looks like this:

    I have a laptop with a standard headphone socket. All I need is it all connected up to play music to both speakers. Daisy chaining does not work I don't know why I tried for ages and talked with the person at the shop about it I don't know why it just doesn't (my bad i guess!).
    I don't mind if they don't come out one Left one Right but just they come out with equal volume from both speakers via the mixer which can come straight from the laptop. This is purely for a house party so nothing fancy. It would be literally INCREDIBLE if you guys could just point me in the direction of what leads I need.
    Thanks for taking the time to read this from the biggest newbie going!

    Tim :)

    I wonder if your lack of success has as much to do with mixer control settings as cable connecting - there's a lot of scope to go wrong!

    I have no definitive answer as I don't use a mixer therefore I can't guarantee this will work but as there are no other replies, yet, here goes...

    Assuming the source signal from the laptop is stereo analogue, then I'd try feedng this signal into the AUX IN (both left and right channels) on your mixer. I'm assuming that using the mixer's AUX IN will bypass all of the various individual channel EQ and individual channel volume control facilities on your mixer (as I understand it, this is what AUX IN's usually do) - I think this is the best way to connect for a party (less scope for others to meddle). So to connect from laptop to mixer, you'll need a cable terminated with a single stereo 3.5mm male plug at one end and two RCA/phono male plugs at the other end. Such leads are cheap and readily available. Example:

    Pure HQ OFC 3.5mm Stereo Jack to 2 RCA Phono Plugs: Amazon.co.uk: Electronics

    I think the two-channel output from your mixer should come from the MAIN MIX (bal/unbal, L & R) sockets. The mixer output needs to plug into each active speaker's LINE IN RCA/phono socket so you'll need two separate cables terminated with a 1/4 inch (or 6.35mm) mono male jack plug at one end and a RCA/phono male plug at the other end. One cable will feed the right speaker, the other cable will feed the left speaker. Again, such cables are cheap and available. Example:

    http://www.amazon.co.uk/6-35mm-Mono...=8-33&keywords=1/4+inch+mono+jack+plug+to+rca

    Ensure you buy suitable cable lengths. The examples given are not recommendations as I've no idea as to their quality. If you're fortunate, you'll already have the necessary cables and adaptors to make up some or all of the leads you want.

    You could try posting on a forum more geared to professional audio equipment for confirmation before commiting to purchase.

    There are two methods that I can think of, one with the mixer, and one without the mixer. Dogfonos has cover the essence of it.

    The Computer has a Stereo out, so you need a cable to match the stereo out of the Computer, then break that into two wires, one of each Mixer input.

    3.5mm Jack - Phono Cables - Audiovisual Online - Home Cinema and Hifi Specialists

    This is an extremely common cable and any audio, music, or electronics shop should be able to provide you with one.

    The mixer must be Stereo because it has Left/Right Pan or Balanced controls.

    Using the cable recommended by DogFonos, plug each of one channel of the Computer into one input channel on the Mixer.

    Set one mixer channel to the LEFT using the Pan/Bal control. Set the other mixer channel to the RIGHT using its Pan/Bal control.

    Set the Mixer channel volumes to about 0dB which I'm guessing would be about 2/3rds to 3/4ths of a turn of the channel volume dial. Once that is set, use the Master Volume Control of the mixer to control the volume.

    Plug the Left output of the mixer to one speaker and the Right output to the other.

    Setting the volumes, because there are so many, can get a bit tricky. Likely the volumes on the Mixer channels and the Volume on the Active Speakers will need to be fairly high, 2/3rd or more. The volume on the Computer's sound card will have to be full on.

    Once connected and working, the general sound is controlled with a combination of the Computer Application Volume Control (iTunes or whatever) and with the Master Mixer Volume Control.


    The alternate method is directly from the Computer to the Active speakers.

    You start with the same cable -

    Though you will need one long enough to reach to the speakers. There are ways to get extension of splices for cables like this.

    https://www.google.co.uk/search?hl=....180.1337.1j10.11.0...0.0...1ac.1.sCU2_teMBtg


    Use one of the Couplers shown, and standard RCA-to-RCA cables to extend as far as you need. Though we would hope each cable would be less than about 15 feet.

    Standard RCA-to-RCA cables are usually in Stereo Pair. However, you can get RCA-to-RCA Subwoofer cable with is a single RCA cable, Run one to each of the speakers.

    Superfi - QED PROFILE SUBWOOFER INTERCONNECT

    Subwoofer Cables - Audiovisual Online - Home Cinema and Hifi Specialists

    The price varies with the length.

    So, directly from the Computer to the speakers. Again, balancing the various volume controls can be tricky. Likely the Active speaker would need to be set near full volume. Then the Computer Application (iTunes...whatever) can control the volume of the music.

    Does that help? Is there anything you would like us to clarify?

    I would go with 3.5mm (headphone) to two RCA and put it on your input on the top right. Should work fine.
    If it doesn't get it with your iPod mobile etc because if that doesn't work your mixer is broke

    You'll need rca to rca on the output of the mixer to the speakers. should be s doddle
