Can I connect this mixer to a main mixer with 17 channels that is connected to an amplifier?

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

An external equalizer will not help this at all. The problem is likely within the amp (feeding the main speakers), the connections from the board to the amp, or the speakers themselves. In other words, the answer would be "NO." Best of luck!

Look under "Downloads" tab at bottom for owners manual info. In a nutshell...mic to mixer channel #1, mixer connected to power amplifier, amplifier connected to speakers. Start with zero volumes on all equipment, bring up amps 1st (1/2 volume) and then adjust mixer until sound is heard from the microphone.

Use a two channel INSERT SNAKE. Plug the TRS connector for each channel into the INSERT jack for the mains in the area above the effects unit. Plug the TIP of each channel of the snake into the input of your effects unit and the RING plug into the output of your effects. The snake has ONE TRS connector and TWO TS connectors per channel.

Instructions

1. • 1

     Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.
     

   • 2

     Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig
     

     
     

   • 3

     Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.
     

   • 4

     Power on your mixer and amplifier. Test each microphone connected to the mixer for output.
     

   • 5

     Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.

The output of mixer connects to channel A or B of the separate amplifier and the output of the am connects to the speakers. Amp channels are listed as A and B or 1 and 2 instead of Left and Right because the manufacturer does not assume how you may wire your system. Please remember that compression, limiters and EQ device connect between the mixer and the amplifier with their prespective IN and OUT levels adjusted accordingly.

There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system. There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder. The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.

You will need either powered speakers or an amplifier for the speakers. If you have powered speakers with built in amplifiers, use balanced audio connection cables from the MAIN outs of the mixer to the speakers, Use XLR or 1/4 inch TRS cables.
If you do NOT have powered speakers you will need amplifier as well and speaker cables in addition to the audio connection cables above.

The first thing to do is to swap teh L & R INPUTS to the amplifier. Did the speaker that works change?
If som the problem is with the setting of the mixer deck. If it did not change, then the problem is with your speaker wiring of the dead speaker, the speaker itself, or that side of the amp.
If the working speaker did swap, that means problem is with the mixer. The question then becomes how are you connecting to the mixer. You should be using TRS 1/4 inch connectors or preferably XLR from the MAIN outputs. These are balanced outputs connections.
If the inputs are from one of the mono inputs, the PAN control for that channel will control how much goes to each speaker... If at center, both will get same signal.
There are so many possibilities that I can't evaluate them until you try the test to find if it is problem of the amp or the mixer that I have given you to try.

You must connect:
the main out of the 1002, or the ctrl room out of the 1002 at your power amplifier's input.
the line in 9/10 of the 1002 at your 2496's line out.
the cd/tape out of the 1002 at your 2496's line in.
in case of a cd connect it's line out at line in 3/4, or line in 7/8 of 1002
some mic at the mic 1 or mic 2 of 1002.
That's the way you're going to have control for:
the mic level from channel 1 or 2.
cd level from channel 3/4 or 7/8.
pc playback from channel 9/10.
master speakers from main mix or ctrl room.
All the above connections are not absolute and may vary depending on your needs.

In case of a problem or clarification, don't hesitate to post.
