The Heil Sound PRAS (Parametric Receive Audio System) is a specialized base station audio processing unit engineered to significantly enhance communications receive audio directly from your transceiver. Designed specifically to address the varied frequency responses of different voices and operating conditions, the system employs a three-band parametric equalizer allowing operators to sculpt high-end clarity, boost or cut specific midrange voice peaks, and eliminate low-frequency rumble. With an integrated analog audio level meter, dedicated dual headphone outputs with individual level controls, a 1/8" record output, and versatile rear-panel connectivity—including balanced XLR, 1/8", and standard 8-ohm inputs—it delivers studio-grade listening clarity for weak-signal DX, contesting, and everyday ragchewing.
