Have you checked fuses? You may have overloaded the amp and caused a fault internally. I have experienced power supply faults with Mackie products, but it may be a simple fix. Find a local repairer to have a look at it.

Hello,Well this is a common issue with this mackie design, the 90% of this report comes out of a cracked output Mosfet's pins or Coil at output section, let me know further to help more.

Scroll down to "Get Manual" at the web page and click on it to download. The files are compressed but you can use the free decompressor to extract or view them.

Some sort of feedback. Try grounding the input or connecting a source that is silent. If it still does it, time for the repair shop. This may be close to the schematic:

Scroll down to the link "Get Manual" and click to download a compressed file with two parts. One is the electronic crossover, the other is the power amp.

There is a mute control if signal is not present and also a gain limiter. This may take some troubleshooting by an experienced electronic tech. I would look for something wrong in these two parts of the circuit.

The amp is likely blown. This is not DIY unless you are competent at electronics.

There are more than one fuse and they are internal. Replacing the fuse without fixing the cause MAY result in causing more damage to components. The fuse is inside to force one to open the box to repair.

Here is schematic:

If your Mackie SR1530 is powering on but you're not getting any sound, there could be a number of potential causes. Here are a few things you can try to troubleshoot the issue:

1. Check your connections: Make sure that all cables are properly connected and securely plugged in. Check both the cables going into the speaker and the cables that are connected to your audio source.
2. Check your audio source: Make sure that your audio source is turned on and properly connected. Try connecting a different audio source to the speaker to rule out issues with the source.
3. Check the volume levels: Make sure that the volume on both your audio source and the speaker are turned up. Try turning up the volume to see if you can hear anything.
4. Check the input settings: Make sure that the input settings on the speaker are correct. For example, if you are using an XLR cable, make sure that the input on the speaker is set to XLR.
5. Test the speaker with a different audio source: If you have access to another audio source, try connecting it to the speaker to see if you can get any sound.

If none of these troubleshooting steps work, there may be an issue with the speaker itself. It may be a good idea to contact Mackie customer support or a qualified audio technician for further assistance.

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

I would check the insert socket.

I doubt the issue will be the regulators if you have the correct voltage on them. Check where the hum is coming from. What frequency is the hum; 50/60HZ = mains hum = bad ground. 100/120HZ = power supply hum. Affected by a control somewhere maybe.

This unit will require an amp. I have set up several mixers and I do not watch output level numbers, you can get desired volume using amp. It does no good to drive input levels high output levels high and the turn down amp. Lower your inputs so no light flashes set master gain to -6 output and then raise amp volume. I have set up 16 mic mixer set individual levels and the feed to main mixer and controlled levels with one fader. I have taken mixes from main mixer to another mixer to control audio on video feed. A good band does not let member's set their levels . the audio person set levels, bad bands have members to set own level with resultant a mess that gets louder and produces sub par event. Remember good bands sound good and bad bands only sound louder, and bad
