Bought a powered monitor as it said to do in the
You haven't mentioned what model and manufacturer the mixer is. I will have to guess and say that the monitor out on the board isn't providing signal to the powered monitor or the monitor out on your board is powered and is now damaged by plugging a powered monitor into it. Carefully reread your manual and determine if the monitor out on your mixer is powered or line level. Reread also and make sure that the signal you are monitoring is assigned to monitor out, levelled correctly etc. If you find that the monitor out is passive (line level) try hooking it up to an external power amp and speaker. A guitar amp will do for testing purposes. Start with a low input volume on the amp. Also make sure that if it is passive to use a shielded cable from monitor out to input. If your board has powered monitor outs you can use a speaker cable from monitor out to speaker input (non powered monitor speaker).
Bought a powered monitor as it said to do even
You didn't mention what brand powered mixer you have, HOWEVER MOST powered mixers also have a line level monitor and main output jacks. These are almost always 1/4 inch jacks. In any case you should be using BALANCED lines to the powered speakers using either XLR or TRS connectors on the ends. Please tell us what powered mixer you have so we can give you better answer regarding which connections to use. IF for some reason your mixer does NOT have line level outputs, you can use a high level Direct Box to condition the powered outputs to be sent to the powered speakers..
Also make sure ALL your interconnected equipment is powered by the same receptacle or source to avoid damaging due to ground bounce on utility lines and circuits. This often means running an extension cord from the stage where the powered speakers are along with a snake of the audio cables.
Guitar amp? whining noise regardless of connections or volume settings?
Several possibilities (i have experienced all):
- 120V.AC line noise. Try moving to a new receptacle in a different room or breaker. Try a In line AC filter (like a Furman power filter/conditioner)
- RF interference. Plug in a different core and guitar to isolate.
- Guitar wiring. Bad ground internally or pot (volume) became ungrounded.
- Defective amp preamp section. Pot or transistor.
