The LDG Electronics AAF7 Analog Audio Filters are external audio processors that help to improve overall signal readability by reducing the audio passband to include only the part of the signal you want to hear. Featuring a Lo Cut adjustment range of 50Hz to 500Hz and a Hi Cut adjustment range of 500Hz to 10000Hz. Gain and parametric equalizer frequencies are also selectable from the front panel, allowing for easy adjustment of the filter to suit your operating mode.

The AAF7 also features a 3.5mm TRS headphone jack on the front of the case, and on the back, a 3.5mm TRS Audio input jack, an RCA jack for line level output to feed into another devices such as a recording setup, a 3.5mm TRS speaker jack with 5W of audio power and a 5.5 x 2.5mm coaxial power jack with a positive center. The case measures 7.00 in. x 3.50 in. x 1.5 in, meaning it will slip into your shack using minimal space. A power cable and an audio cable are included to facilitate hooking the AAF7 up in your shack.
