The RDL FP-MP1 Studio Quality Microphone Preamplifier is the ideal choice in most applications where mic to line preamplification is desired.
Power connections are made using either the full-size barrier block terminals or a dc power jack located in one end panel. A second dc power jack is provided on the other end panel for connecting additional FLAT-PAK modules. The FP-MP1 features an XLR microphone input jack and an XLR line level output. The module also provides a plug-in terminal block for direct wiring to the input and output. 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. A low frequency roll-off filter is selected by another front-panel switch. Each of these switches is recessed to avoid inadvertent actuation. Final gain adjustment is set using a front-panel single turn trimmer while observing the LED output level meter. The dual LED output meter follows standard VU ballistics. The intensity of the green LED progresses from minimum at -11 dBu to full intensity at +4 dBu. Flashing of the red LED is equivalent to a VU meter needle swinging above the 0 level.
RDL's exclusive low noise discrete preamplifier circuitry produces studio quality low noise performance in an economical preamplifier. The XLR and plug-in terminal block connections make the FP-MP1 the ideal choice for both rack mounted hardwired installations and remote use with standard audio cables. The FP-MP1's low profile and compact size permit mounting in confined spaces and in various locations in equipment racks.
