Radio Design Labs FP-PA20A
20W Power Amplifier with 70 & 100 V Outputs

OUR PART #  FP-PA20A


NOTE: Radio Design Labs' PS-24V2A 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-24V2A power supply.

Radio Design Labs' FP-PA20A features a balanced line level input that may be connected unbalanced. A front panel gain control is designed to be adjusted either manually or with a trimming screwdriver. The gain range will accommodate standard unbalanced levels as well as professional balanced levels. Both a 70 V and 100 V amplified output are provided to drive corresponding speakers in a distributed sound system. Audio levels that could cause the amplified output to clip are compressed using two dynamic time constants designed to preserve aural transparency. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics and preventing the compressor from increasing feedback potential when the amplifier is used for paging. The FP-PA20A produces average audio levels and audio clarity normally expected of amplifiers delivering much higher output power.

Radio Design Labs FP-PA20A Features:

  • 20 Watts RMS Constant Voltage Amplifier
  • 70 V and 100 V Outputs
  • Integral Audio Compressor to Control Clipping
  • High Overall Operating Audio Level
  • Maximized Audio Level for Output Power
  • Audio Quality Superior to Standard Amplifiers
