Tapco MIX10FXP Manuale Utente

Appendix A: Service Information

If you think your TAPCO powered mixer 

has a problem, please check out the 
following troubleshooting tips and do 
your best to confi rm the problem. Visit 
the “Talk To Us” section of our website 
(www.tapcoworld.com) and contact 
our technical support heroes and get 
some ideas. You may fi nd the answer to 
the problem without having to send your 
powered mixer away.

•  Is the break switch on?
•  Is the EQ set up nicely?
•  Is the gain switch set correctly?
•  Is the level up enough?
•  Is the channel OL LED on?
•  Try the same source signal in another 

channel, set up exactly like the suspect 
channel.

•  Is phantom power required for your 

microphones?

•  Is the main master level control turned 

up?

•  Are the graphic EQs set to reasonable 

levels?

•  Is the FX level going to the main mix too 

high (OL LED on)?

•  If it’s one of the main speaker-level 

outputs, try unplugging its companion. 
For example, if it’s the 1/4" left main 
output, unplug the left Speakon output. 
If the problem goes away, it’s not the 
powered mixer.

•  If a left speaker is presumed dead, 

connect it to the right output instead. 
If the problem stays with the same 
speaker, check the speaker wiring, or 
any speaker fuses.

•  Unplug anything from the main line-level 

outputs, or other line-level outputs, just in 
case one of your external pieces has a 
problem.

•  You may be overdriving the amplifi ers. 

Check the loudspeaker average load 
impedance is not less than 4 ohms. 
Check the speaker wiring. Check that 
the meter CLIP LEDs do not come on.

•  Turn the channel levels down, one by 

one. If the sound disappears, it’s either 
that channel or whatever is plugged 
into it, so unplug whatever that is. If 
the noise disappears, it’s from your 
whatever.

•  The power LED should come on if the 

powered mixer is connected to a 
suitable live AC mains outlet, and the 
power switch is on. Check the power 
cord is securely plugged in.
