Microphone Preamp

Single channel only

This device gives you a single XLR microphone input with preamp and 48V phantom power with a USB connector on the backside. No need for an external power supply or external preamp. If you are making acoustic measurements and using a phantom powered condenser microphone and require extremely portable operation this device is an ideal solution!
