Hi microphone specialists what you read so get there? Condenser microphone needs 48V is also always above in the description (Amazon) as well meim seller Kirstein Music Store. A small accessory can be found at the mixer so heist! M-502 with Panthomspannung 48V for 39.90. Such mixers are available with USB, however, a bit more expensive. The connection cables are called XLR. Pronomic CM 11 / CM 22 are for domestic applications or like me on the radio just great for the price. In microphone eg CM 11 is a switch (low-cut) is to lower the frequency of 100 Hz (bass) MFG Olaf
