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.

•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.

Troubleshooting

Bad Channel

•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?

Bad Output

•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.

Noise

•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.

Power

•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.
