Radio Design Labs FP-MP1
Microphone Preamplifier

FP-MP1

The 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.
