There is no way to directly connect this mic via USB. It requires a phantom power source, through an XLR mic cable.

Need HELP connectn my phantom power supply to my cad 179 to my LAPTOP HP PLAVILION ASAP!!!!!!! I just bout it not even 24 hours ago and i feel like i got playd as a joke lokz any one with advice pls...

The CAD179 condenser mic DOES require Phantom power and will not work without it. You say phantom pwer supply...but fail to mention what type you have. FRANKLY using a high quality microphone you should be using a good quality interface to the computer and NOT just trying to use the internal audio in the Pavilion computer. Not knowing what power supply you have we can't really give you much help. In general if you ahve a mic preamp that has phantom power you will turn on the Phantom on the interface and then using PROPER cables one could tie into the audio of the computer. One also has to select the appropriate input for voice in the control panel of the Windows in the computer. You MUST verify the type of cable between the preamp and the computer as that from a high quality preamp will likely be BALANCED and that into the PC is not. Without more info I can;t help you more than that.

I'm using an old DBX 2031 thats probably hasn't seen the light of day in about 2 years. When I chain this thing on my vocals, the SNR just goes through the roof. Pushing faders in any direction will...

Putting an EQ in the chain after a vocal mic can add quite a bit of noise to the signal as the EQ is actually another gain stage prior to the mixer's input. I would recommend the cleanest signal possible from the mic to the console. Add eq after the fact, whether outboard like your DBX, or in the digital realm in your DAW. Keep the signal straight and clean as possible from the mic.

I'm trying to connect a dbx 128 and 118 to my adcom565 preamp, teac tape deck, onkyo tuner, anf radio shack cd recorder, but i'm not sure it can be done. Can anyone help me?

Of course it can be done.

I'm wondering, what's the NEW piece of this puzzle? New dbx gear?

The preamp has two tape loops plus a processor loop (essentially 3 tape loops). You can discount the tuner for this discussion as it already has a dedicated port.

Here's what I would do (and have done *). Get yourself a dbx 400 or dbx 400x Program Route Selector and simplify all of your current and future analog hookup options.

(* I, too, have a CD recorder and a tape deck plus some different dbx units (4bx, 110x-ds; 224) and other toys.)

One on eBay at $59 (a steal so far) expiring Mar 9:

and a link to the manual so you can see how it works:

It takes up ONE tape loop and allows attachment of 3 processors and 3 tape decks PLUS a dbx-style noise reduction system if you have one; and can logically rearrange the processors to be in line with any source and BEFORE, AFTER or BETWEEN tape decks with or without the Noise Reduction Processor involved, all via front panel illuminated buttons.

If you don't want to go the 400x way your options are severely limited re: the tape deck because even though the dbx processors can fit in nicely on the preamp, I don't think the preamp can place them in front of AND after the tape decks, depending on your desires for pre- or post-processing.

Doesn't turn on remotely or manually,

If this is a standard tv, then there are two bad caps. Near the powerline regulator on either side. Look for a 160volt 1MF cap and on the other end a 160volt 4.7MF cap. I don't know the particular model, but you will be searching the horizontal deflection. Is the fuse good? If not you will have to replace the horizontal transistor and look for two, 2 watt resisors at 12ohms and a new fuse as well. Can you do it?

Behringer MX 3242x Mic input not working

Unfortunately, the way the mic preamp and gain control are surface mount components on the PCBoard, it's unlikely you'll be able to do it yourself. Best take it to an authorized Mackie repair shop, or send it back to Mackie.

Preamp noise

Hi KenO2

First thing to check is that the phantom power is not turned on. If you are using a condenser mic, then it should. If you are using dynamic mic, then it will crackle and makes weird noises in the manner you describe. Other than that it sounds like you have a failing op amp in your preamp. This sort of repair work is not expensive(with respect to the outcome). I would anticipate $40-60 to fix it. Trouble is you can replace it super cheap at the moment 45% off for $64.95plus $9.95 shipping from zzsounds

So I guess that it may not be worth repairing, and more a replacement item for that money. If you have a mate with electronics experience, you could just replace the opamps at home for $10 worth of parts.

If you think my advice helped you to work out what to do, a FixYa rating would be great. Cheers

I don't recommend this, but the resistor you speak of is probably a small fuse. Try jumping out the fuse, then turn on unit for brief moment. If it powers up, fine. Replace jumper wire with 1 amp fuse. If not, take to prof. tech.
