The Heil Sound PRAS-EQ Parametric Receive Audio System Equalizer is a state-of-the-art audio system that enhances the sound of Amateur Radio, shortwave, commercial, and CB receivers. The PRAS-EQ allows radio operators to modify, shape and improve the audio output of their receivers using three separate equalization controls.
Midrange frequencies are the most critical for achieving clear voice articulation in receive audio, especially for those with hearing deficiencies. The PRAS-EQ allows operators to have unique control over these important frequencies. First, operators can adjust the parametric midrange filter from 400 Hz through 4 kHz, with the recommended sweet spot being at 2.5 kHz. In addition, operators can control the presence of these midrange frequencies plus or minus 15 dB. Combined with a low-frequency filter down to 160 Hz, and a high-frequency filter up to 6 kHz, the Parametric Receive System provides operators unparalleled control and quality of their receive audio.
The PRAS-EQ has three audio Inputs; a standard XLR, a 1/8 in. (3.5mm), and a 1/4 in. mono 8 ohm input that can accept the 8 ohm external speaker output of any radio.
Three audio Outputs on the PRAS-EQ are one balanced XLR and one 1/4 in. (6.35mm) outputs on the rear panel and one 1/8 in. (3.5mm) output on the front panel for recording audio. The PRAS also has two built-in headphone amplifiers with separate level controls and dual 1/8 in. headphone outputs.
The PRAS Parametric Receive Audio System is intended to be used with the specially designed Heil HPS-5 Powered Speaker, now sold separately. The line level output of the PRAS-EQ unit may be used with any powered speaker.
