The AR501 Mic Preamplifier for DSLR Audio from Fostex is a camera-mountable mic preamp that offers 48-volt phantom power and can be used for location recording, ENG, and installation applications. It features a balanced XLR input and output in addition to an unbalanced 3.5mm output connector that can be attenuated -10 or -50 dBV for connecting to your camera's mic level input. 

The AR501 is powered by a single AA battery and supports three selectable input gain levels. An integrated and selectable high-pass filter can be engaged at 80 or 160 Hz to help eliminate low-frequency rumble. The included joint plate allows you to cascade 2 AR501s for stereo use.

  • Peak LED and Power LED that doubles with low battery warning
  • Powered by 1x AA battery for 10 hours operation (approximately 4 hours with 48 V on) or DC-IN (5 V, Micro USB)
  • Power saving mode (phantom power down to 24 V) to extend the operation hours
  • Extruded aluminum chassis
  • Shoe rails for various camera rigs and a tri-pod compatible screw hole
  • Stereo mini OFC cable included for DSLR connection or cascading to another unit
