Mackie 1604 VLZ 3 16 channel Analog Mixer Questions & Answers
Every input channel has a green light on when all
Just worked on one of these. What causes this is when one of the 16 volt plus or minus supplies is shorted out or low. Check the supply voltage and PRAY that the fault is NOT on the main board... takes a lot of time to pull all the knobs and unscrew the main board and the headphone jack to get the board out. The one I fixed had the MAIN insert driver blown causing no main output. Here is your service schematics... note there are SLIGHT discrepancies depending on the vintage of your unit.:

You can access the power cable to the main board by removing the bottom access panel. You will find the voltages reading across the connector from left end as +16, grd,-16 and then several others including one at about 9.5 volts and then the phantom power at around +48 volts... You may find the -16 or +16 pulled to the opposite polarity if one of the regulators has failed. This supply runs very hot and seems to be enclosed in a mu-metal magnetic shield as well... or at least the one I repaired had that.

No there is no special cord. The aux you use for a monitor should be pre fader( that means the signal comes before the volume slider) turn the individual slider all the way down. Talk into the mike at the volume you would be singing at the loudest. Adjust the gain of that chanel up untill the clip light comes on. Now back it down so it dosent come on at your loudest. Now pick the aux you want to use. Turn it up 1/2 way, turn up the master aux send coresponding to the channel aux number 1/2 way you should get sound. If it's too loud turn it down if you need more turn it up. If you have any more questions, give me a call at the shop.

Transformer appears dead no lights no output
Transformers are VERY reliable. Look for another problem... rectifier, filter caps, fuses, regulators. There is a main fuse and if it is blown, repair the unit before applying full power. To test the unit, put a 40 watt light bulb in series with the hot side of the power cord. The light will act as a resetable fuse and will light when there is a short within the mixer, thus absorbing most of the voltage. Enough current will flow to diagnose the problem.
My Mackie SR1530 is powering on but no sound.
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:
- 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.
- 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.
- 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.
- 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.
- 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.

Mixer signals is on but qsc 1450 amp not giving any sound when main output is connected but when run aux send to amp it gives sound. What might be the problem.
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:
- 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.
- 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.
- 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.
- 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.
- 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

Mackie CR1604 mixer hum on all channels
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.

Master volume not registering at correct level. Profx12
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
