20 Most Recent QSC RMX 5050 5,000 Watt Power Amp Questions & Answers


Why does it keep going into protection mode?

There are several circuits that can prevent start up, not the least of which is the power supply itself. Check the owners manual, it may tell you about conditions that could cause this. The next step is to open it up. There may be something obviously wrong, burnt, disconnected or stressed. Barring that, we'd be into board and component level testing. If you know what your doing, the output stages of these high power amps are a good place to start.

How do I do transposition in e16 Roland?

To transpose a sound on the Roland E-16 keyboard, you can use the Transpose function. Here's how to do it:
  1. Press the FUNCTION button and then press the TRANSPOSE button.
  2. Use the + or - buttons to select the number of semitones you want to transpose the sound. The range is -12 to +12 semitones.
  3. Press the EXIT button to exit the Transpose function.
Once you have transposed the sound, it will be played back at the new pitch. Keep in mind that transposing a sound may affect the overall tone and timbre of the instrument, so you may need to make additional adjustments to achieve the desired sound.

Baldwin Pianovelle RPS keyboard silent

If the demo on your Baldwin Pianovelle RPS keyboard is playing silently, and there is no battery powering the keyboard, then it's likely that the issue is with the keyboard's internal components. Here are some steps you can take to troubleshoot the issue:
  1. Check the volume: Make sure the keyboard's volume is turned up and not muted. Look for a volume knob or button on the keyboard, and adjust it accordingly.
  2. Check the headphones: If you're using headphones, check to make sure they're properly plugged in and not damaged. Try using a different pair of headphones to see if that solves the issue.
  3. Check the speakers: If the keyboard has built-in speakers, make sure they're properly connected and not damaged. If the speakers are damaged, they may need to be replaced.
  4. Check the power: Make sure the keyboard is properly plugged in and receiving power. Check the power cord and outlet for any damage or loose connections.
  5. Check the demo settings: It's possible that the demo is set to play silently. Check the keyboard's manual for instructions on how to adjust the demo settings.
If none of these steps solve the issue, it's possible that there's a problem with the keyboard's internal components, such as the sound card or amplifier. In that case, it may be best to contact a professional technician or repair service for assistance. They will be able to diagnose and repair the issue with the keyboard's internal components.

Casio wk 3500 does not turn on

Check the polarity on the adapter plug. It must correspond to the diagram on the keyboard . If it's reversed, just cut and resolder the cable that connects to the keyboard. My 3500 also has a similar problem. It only switches on if I plug the power and immediately press start . If I wait a few seconds it won't start.

My technics sx-px222 digital piano suddenly has no sound but all lights work and i hear a very very slight hum. Fuses look ok. What do you recommend i try next?

Hi, please check that the volume-down button isn't stuck and therefore forcing the volume of your piano to decrease. You might wiggle the button from side to side if you noticed that it's stuck. If possible, attempt to route the piano sound to an external speaker and see if you receive the same results as you initially did. Thank you.

Orla GT8000 electronic organ. Where can I purchase the bolts/screws to secure the top manuals to the bottom cabinet please?

Question edited for clarity, and it appears to be an 8000 not 800. Question moved from Washing Machines category. No maker, no parts lists. The best bet is the fixings aisle in Home Depot. https://www.google.com/search?q=orla+gt8000+parts+manual ..

I have an electone organ that when turned on its all static nothing else

If you have speakers connected to it, disconnect them to see if the static stops. If there are no speakers clean the on / off switch and any volume controls with electronic switch cleaner. Other ideas here https://www.google.com/search?q=electone+organ+static+noise ..
