C1 not working

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

A short on the XLR input board, or possibly a short within the XLR connector itself.

From the Micropower PS400 product description it states:

"routes the microphone signal to a mixer or a microphone preamplifier."

• these is just a phantom power supply.


One reason your former setup is OK , is that

tascam m-50 is a mixer preamplifier.

• phantom power supply is just a part of the mic preamp of the mixer

to power up your mxl 990 condenser mic


• What you may need is something like these:

X2u XLR to USB Signal Adapter

Your condensor mic requires special electrical handling usually reserved for proffesional audio equipment, not a PC. You will need two pieces of equipment, a short XLR cable and an adapter cable.
1) Behringer PS400 Ultra-Compact Phantom Power Supply.
This will supply the mic with necessary Phantom Power.
2) Rapco Horizon ISOBLOX Transformer Isolation 1:1 BLOX Device
This will isolate the Phantom Power from your computer, allowing it to work as necessary.
The adaptor connector cable you need will be a female XLR (with pins 1 and 3 shorted, pin 2 hot), through a cable connect to a 1/8" mini plug. They connect in that order with a short XLR cable between 1) and 2). .

No.

All microphones have to be hooked to an amplifier to work. The socket at the bottom with the 3 pins in it is called an XLR jack. You need to plug an XLR cord into that and then plug it into an amp that has an XLR or 1/4 inch microphone input (using an adapter).

If she just wants it for looks, then no, you don't need to plug it in.

Professional condensor type mikes require a phantom power source to work. That will be a balanced (read XLR) connection from source to preamp and the preamp must be capable of supplying the power. These units cannot be used in an unbalanced circuit (like 1/4" or computer mini-pin). Your best bet for the setup would be to get an external power supply box that can also convert the signal from balanced to unbalanced. That would be what the mike plugs into and then that plugs into the computer. You're probably looking at about 50-100 for even a cheap one that will work well. Companies like Sweetwater and B&H should be able to steer you toward a decent basic unit. If you happen to have a mixer (which is why you bought the good mike) then it may have phantom power for some of its mike inputs.

You need a 48volt phantom power supply and 2 balanced XLR microphone cables.

if you have a volt meter check the supply is working correctly
48v dc phantom power should be found between these pins on any xlr mic cable.

pin 1 and pin 2
also between pin1 and pin 3

make sure you have amps turned down before checking/switching 48v phantom power

as if all is up and running it can cause big noise in the speakers.

let me know how it goes

The Samson CO2 is a condenser (also called capacitor) mic, and thus requires phantom power to operate. In order to apply phantom power, you must have a board capable of handling an XLR connection, and supply phantom power. Usually there is a switch located near the XLR-input jack on your board - if you post your sound board type, more help can be given.
