Review Summary For : Heil Sounds, Parametric Receive Audio System
Reviews: 27MSRP: 499.99
Description:
The PRAS is a complete audio system which by passes the poor response of internal audio systems of amateur radio, shortwave, commercial and CB receivers. The PRAS allows the operator to improve signals using the unique mid parametric equalizer to dial the all important mid range speech articulation of frequencies from 400 to 4 kHz. The bass and treble, plus or minus 15 db controls set the outside frequency gates to 160 Hz and 6 kHz. The HPS-5 speaker system uses a Heil 5" woofer in a tuned cavity and a 3.5" titanium tweeter driven by the internal Heil amplifier which delivers 25 watts at .1% distortion. The PRAS is a major factor to help those with hearing impairments. Left and Right headphone amplifiers for balance or can be used for operator and logger. A line level record output is located on the front panel.

Heil Parametric Receive Audio System Crisp & Clear Time Owned: 6 to 12 months.
In the six months I have owned the Heil Parametric Receive Audio System, it has performed flawlessly. No RF issues here whatsoever. Licensed now more than 50 years, my hearing isn't what it use to be.
Recently purchased a new ICOM 7300, and immediately connected it to the Parametric Receive Audio System. Big difference from the internal speaker. Recently attended my 32nd annual Dayton Hamvention. Spoke with Bob Heil for a few minutes, told him how well my Parametric Receive Audio System performs. The adjustments allow me to optimize the sound for my hearing. I'd say if hearing loss is becoming an issue, this is the way to go. Crisp & clear.

Both hams in the house love it. Time Owned: 3 to 6 months.
Bob Heil did a presentation to our club and, as part of it, did a demo of the PRAS. It made good sense and sounded great. The very next day, my wife ordered one. Part of the attraction of this unit, in our situation, is that we share a good sized home office with the hamshack in one corner. My wife had a hard time hearing what was going on when I was using the HF radio with just the speaker on the front of the radio (IC7200). With the PRAS, she has excellent copy on her side of the room. The adjustments allow us to optimize the sound for our hearing so it's a nice addition to the shack. We both highly recommend it.

We also found it a pleasure to deal with Bob's company. As a side note, when I was a new general licensee in the late 50s, I used to occasionally talk to a young Bob Heil, K9EID on 75 meter AM. 73 K9LJB

Great Product Time Owned: 0 to 3 months.
Dr. Heil
Just received my new PRAS. Followed the instructions sent with the unit quickly, and turned it on. My expectations were greatly exceeded – I have a pretty serious hearing problem because of Firearms training as a police officer. I wear hearing aids as a result and SSB has always been somewhat of a problem. I had to wear headphones to comprehend the audio of most SSB stations. I purchased the Heil Pro Set Elite, and that helped some, but still comprehension was difficult. But with the PRAS tweeked, I could not believe my ears. I am now able to use the attached HPS-5 speaker –every syllable is crisp and clear. I did modify my Pro Set Elite headphones – with a splitter so that I can control each headphone speaker individually. Absolutely zero RFI as well. This piece of Heil audio equipment is supreme. Thank you Bob Heil.

Works as Avertised Time Owned: 0 to 3 months.
Improved receive audio just as advertised. Was concerned about RF issues since reading 2 other eHam reviews. So I ran multiple tests, from 100 watts to 1500 watts phone and digital and there were no RF issues until around 1500 watts where there was a slight hum. The hum was eliminated by adding a ferrite choke.

Disappointing Time Owned: 3 to 6 months.
Does what is says on the box, enhances the received audio along with every other scrap of RF it can find. All that is missing from the supplied lead's is a diode probe, would make a great signal tracer!!
Would only recommend for a receive station

works great ,,, but,, Time Owned: 0 to 3 months.
Got this unit a while back and it definitely does allow you to pull signals out of the noise BUT there is one horrific flaw I cannot believe they addressed. The unit is a RF nightmare!! Every time you transmit it is Donald duck through the powered speaker.. and I don't mean just a little bleed, it is incredibly loud and obnoxious, and this is barefoot without an amp! You have to turn the output control off when ever you transmit otherwise it is unbearable! Now its not just me, or something I've done wrong as my buddy also has one and he cannot believe Heil would put out a unit that is a RF horror! Why on gods earth, didn't Heil put in a cut circuit that muted speaker on transmit like they did on their older type units?? For the huge amount of money they charge they didn't check the non existent RF shielding and how it works in a real life situation. I get zero RF issues in any of my home electronics BUT a specific item built for ham radio leaks RF like a pasta strainer is absolutely ridiculous. They need to build an adapter that cuts speaker off on transmit and offer it free to anyone who has bought this unit.

The PRAS works super great! Time Owned: 0 to 3 months.
The Heil PRAS allows me to cut the frequencys where my local noise is. allowing more intelligibility from the receiver. also allows me to tailor the audio from my rig so I can hear the other stations speech clearer and more ballanced! The PRAS has been a blessing in my shack and I highly recommend it to hams who's hearing isnt what it used to be when we where young. Years of big diesel engines running and loud guitar playing and music has taken its toll on my ears. Just like my Dad said it would!!
