The JPS NIR-10 audio filter allows reception of difficult to read signals and reduces listener fatigue. Operates on radio receiver audio outputs then provides its own volume-adjustable processed audio to an external 3 to 8 ohm speaker (not supplied). The NIR-10 reduces or eliminates white/pink noise, ignition noise, static interference, RTTY interference, and power line noise. PEAK function reduces white noise interference. The Notch Filter mode removes multiple heterodynes and acts in 3 milliseconds. Band Pass mode has continuously adjustable center frequency, selectable bandwidths (.25, .6 and 1 KHz) , vertical-skirted filters, and greater than 60 dB ultimate rejection.

The JPS NIR-10 SWL version is the same as above but features bandwidths of 1.8, 2.4 and 3.0 kHz.
