Radio Design Labs FP-MP1
Microphone Preamplifier

OUR PART #  FPMP1


Radio Design Labs' FP-MP1 is the ideal choice in most applications requiring a preamp. RDL’s exclusive low noise discrete circuitry produces studio quality low noise performance in an economical preamplifier. The XLR and plug-in terminal block connections make the FP-MP1 perfect for both rack mounted hardwired installations and remote use with standard audio cables. A front-panel switch permits the installer to direct phantom voltage to the input connectors. This 3-position switch provides 24V, 12V or PHANTOM OFF. Two switches select the input gain range thereby permitting the connection of standard or high output level microphones.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.
