How to hook a qsc rmx 850 to a numark cm100 mixer

If you are experiencing an issue where the QSC RMX 1450 amplifier is not giving any sound when connected to the main output of your Mackie 16 OK mixer, but works when connected to the aux send, here are some possible causes and solutions:

1. Check the main output level on the Mackie mixer. If the level is too low or muted, this can cause the amplifier to not produce any sound. Increase the main output level on the mixer and check if the amplifier produces sound.
2. Check the cables connecting the mixer to the amplifier. If the cables are damaged or not connected properly, this can cause the amplifier to not produce any sound. Ensure that the cables are connected securely and are not damaged or broken.
3. Check the amplifier settings. Ensure that the amplifier is set to the correct input source and that the input gain level is set correctly. You may also want to check if there are any protection modes or limiters enabled on the amplifier.
4. Check the speaker connections. If the speakers are not connected properly or are damaged, this can cause the amplifier to not produce any sound. Ensure that the speakers are connected correctly and are not damaged.
5. If none of the above steps work, there may be an issue with the mixer or the amplifier. You may need to contact a qualified technician to further diagnose and repair the problem.

Remember to always follow the manufacturer's instructions and safety guidelines when working with audio equipmen

That is correct, they will come on when it warms up.

That is correct, it has to get warm first.

You would have to replace them. If they are no longer available, you would have to modify the amp to accept another brand of terminals. If you need more assistance, or would like to inquire about repairing it, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

Hello,

A common issue with the QSC RMX series amp is faulty volume pots, so i would recommend go this way first of all, let me know a bit more to improve help.

The best way is to use a two-way crossover between the mixer and the amplifiers. In your case, the low output from teh crossover would go to the powered subs, the highs to the QSC. Use the crossover adjustment to set the frequency crossover point to get the sound quality you require.

Mackie 1604 ---> Crossover --- Highs ---> QSC --->Speakers

-----> Crossover --- Lows ---> Powered Subs.

you should be fine, you can get splitters, little adapters to split the input cables into 2, so that you can use one ouytput to run 2 channels. just hook up the output cables to the output on the numark, and use the splitter adapter to split the sound between the 2 amps.

something is probably blown

Ronnie, The numark mixer will not project CD+G graffix on the pc. You can only send the audio from the mixer to the pc. To use karaoke on the pc you need files that re MP3+CDG or CD+G discs. Most karaoke systems only support TVs through a video line usually RCA connections. In order to get video to your PC you need a video card or TV tuner card installed. Most people use it in the reverse having their music files on the PC and then streaming to the mixrer and then the audio speakers. Winamp with MEXP and the CD+G plug installed should work nicely for you. Let me know if I can help further I have been a mobile DJ for 20+ years
