Generally the hum is one of two things. If a sensor, pickup, per-amp, or mini-amp are too close to the receiver or speaker, Feed-back may occur or a hum and buzz join the audio signal out. The usual problem is: line in port on the instrument can be defective or the male jack is not making proper contact. If a cord is tested and working, the condition is in the input on the instrument. If a terminal has a loose wire inside the instrument the problem can be intermittent ( come and go) and thus a buzz or line noise may be present.

My Cube 30 hums when I plug my guitar into it, buzzes really loud when on effect channel, clean when plugged into AUX


You have a bad ground somewhere. Try different cables and check the effect channel port if it is tight and secured.

I just purchased a Takamine acoustic/electric EG 350 SC which sounds great until I plugged it into a Mackey sound board. I sounded like distortion was coming out. In other words, it sounded like ****. I...


I ASSUME that you plugged your guitar into a DI box that then used BALANCED XLR cable to the Mackie board??? The guitar generates line level and the Mackie board inputs are mostly mic level... you will get distortion if you overdrive the Mackie board. You could try going into line level jacks, HOWEVER if you go any distance balanced interconnects must be used. Even the line level jacks require using TRS balanced cables. Try is using a DI box, and preferably one with a gain switch. Also fiddle with the ground lift switch on it for least noise or hum. I use the LiveWire brand DI boxes and they seem to work fine. Then it is important to set the gain with the trim on the MAckie so you don't clip. Also be aware that an acoustic guitar can "hear" speakers and you can get feedback or regeneration that will sound like you are in a cave.

TV plays fine when dvd recorder is off. As soon as you turn on recorder the picture gets snowy. It doesn't matter whether it is on video 1 or on the channel setting. I have changed all the cables, still...


It seems that you are keeping the recorder close to the TV set resulting distortion in the picture due to power supply hum,check by keeping it away from set if no change than check the reason of hum received from power supply of recorder by replacing electrolytic capacitors for leakage or proper shielding of power supply in side the recorder.

I have Mackie mixer cfx12 all the channels work except for channels 2 & 3, I turn the pre amp trim pot all the way up but no input is present, I also tried solo PFL for these two channels and no...


I suspect one of the upfront IC amps has been damaged. This can happen if people power the mixer from a receptacle that is different from where other connected equipment is powered such as amp. For example, mixer is at one end of the hall and other inouts such as an output of a guitar amp is plugged in. If a ground fault or spike occurs, teh ground bounce can exceed the common mode voltage of the input amps.

In your case, the inpout amps are discrete transistor types.

A voltage surge into the inputs of your unit would LIKELY pop two bypass caps that are 330pf. For channel 2 these are C205 and C206. Check those for shorts.

VERIFY audio is available at the "send" (tip) of the channel insert connector... this verifies the preamp stage. You can PROBABLY plug a set of headphones in to check this... ONLY one side will have sound of course. Verify this is a good test by checking a working channel. The level will be quite low and we are looking for just some signal.

IF you do have signal on the channel insert send which is the "tip" of the channel insert with the trim turned up, let me know and I will check the schematic for the next thing to check farther down the line.

High pitched squeal when the input jack is used.


Sounds like your master volume is turned up too much. The channel volume will make the squealing go away(caused by high gain and humbuckers). The best thing to do is dial in your favorite presets and change the channel volume to the correct level with the master volume where you usually keep it. I use my Spider Valve at master volume at about noon and the channel volume between nine o'clock and noon. Let me know if this does not solve the problem......

Ch. 10 does not work - Mackie 1604-VLZ PRO


Yes, the ribbon cable is the 1st thing I would check. You can check the ribbon like this: Disconnect said cable from the channels. Connect cable connector from a known good channel to the problem channel. If channel sounds the same trace a signal through the channel op-amps.
