I have the PRASEQ and one HPS-5 speaker. They work as advertised. However I did encounter serious RFI "HOWL" when transmitting high power on 10M. Installed the PALOMAR RFI Ferrites for the PRASEQ (Yes apparently this is a large enough problem that Palomar has built a specific ferrite kit for the PRASEQ). Also HEIL Sound was kind enough to send me power wires that I use in place of their 120->12V wall warts. I am running the power from my 13.8V Anderson power distribution panel to the PRASEQ and Speaker. Last tip for you all, The amount of gain that you dial in to the PRASEQ and on the back the HPS-5 has some bearing on their propensity to pick up RFI. So back those down if you are experiencing bleed in when transmitting. Again for me this was only an issue on 10M using 400+ watts. At 100W not an issue on 10M. And an observation.... seems that you produced more of a demo on microphones than a demo of how to use the PRASEQ. (ie the Sony ECM-B1M and Zoom H6). Would have like you to "show us" how you picked out a signal deep in the slush.... Art W1SWL
Mine was bad even barefoot on 10 with 3 different resonant antennas, just got into it bad. I returned it for a refund. I really wanted this to work, love Heil stuff.
Thanks for demonstrating this! Obviously Heil is the biggest name in town and for good reason. The overlap between electronics in amateur radio and electronic music had me quite curious about equalizer designs and filtering for amateur radio use. I appreciate the opportunity to see how the needs of pulling weak signals out of radio differs from more generic bandpass filtering used in the music audio applications. Cheers!
Heil gear is top notch! Old HAM ears need all the help they can get for a better audible signal.👍 Splitting the signal on the 7610 would be a great option to test with. I prefer knobs for all the most used functions compared to an annoying menu system to memorise and navigate through.👍
Always quality gear from Heil Sound. Will consider a purchase now of the PRASEQ and HPS-5. I own two Heil headset, including the Pro 7 for the QTH and a BM-17 for POTA. The best and Bob Heil is an amazing person.
as a retired live sound guy I've been wondering when devices like this would make their way into ham radio for downstream manipulation of the audio. Cool stuff.
Hi Josh, You can hear the difference with that HPS-5 speaker. Definitely a good call to use it with the radio. The PRAS can heighten different parts of the audio spectrum with a turn of a few knobs. How about the Powerball rolling over to 1.5 Billion. You and your family stay safe. 73 WJ3U
I love Heil stuff, but I will say I bought this unit and RF gets into it real bad. I returned the system. I was in no mood to try all kinds of tricks and beads to get it fixed. I even set the system up on the other end of the house from the shack and my voice was still ripping out of it when I talked. I had the wife listen, and it was no better even being 40 feet away from the shack. I really wanted it to work, and loved how it sounded,,,,, until I keyed down, even barefoot on a resonant antenna it was horrible.
Hi Josh, great video! I have had my eye on that EQ, you got me to pull the trigger. 😀 Hey what is that software on the monitor above to and the left of the 7610? Thx. 73 K6SUD
Hi Josh. The PRAS is great for what it does. It will not play well with 2 receiver radios like your 7610 however. For that I use a small Behringer board and feed it with a stereo signal from a multi rx radio (like your 7610). From there I feed a pair of JBL Control 2P powered monitors. Same results as your PRAS, but now I have the ability to run 2 receiver radios out of 2 different speakers. I can also feed other radios into the board as well like a dual band mobile or a 2nd HF rig. FWIW, I got this idea from an old Ham Nation video that Bob did detailing this setup.
With my old ears and excellent hearing aids I could not perceive better intelligibility. I have done work with different audio processing in my K3 and with my hearing aids and that seems to work as well for me or even better. The amplified speaker from Heil might be a good investment in itself. My Bose noise cancelling headset still works well and is best for my old ears, even over my behind the ears hearing aids.
I have a PRAS and HP5 system on my rigs. Wonderful results. By bumping up mid-range I can understand voices in poor conditions that I could not without it. Firm believer-because it works!
I have the Heil PRAS system in the shack. RF was an issue on certain bands. Choking/grounding, rerouting cables seemed to solve the issue. One troubling issue I wonder if anyone else is experiencing is on the headphone output the volume is very low till I get to about the 5 o'clock position then the volume jumps to loud. No volume level change till the 5 o'clock position. Sent the first one back, got a replacement same issue. I added an inline volume control between the output jack and the headset. One final note this issue was across different headsets including my Heil Proset Elite. This post is strictly my experience and my work around. Not intended as a complaint against Heil products.
Interesting stuff. I find one of the most effective noise reduction techniques is just cupping my hand over the speaker. Works great, and is pretty cheap.
Sure. Give it a try. Play around with your hand position, how far from the grill, how much cupping, etc. the soft tissue absorbs a lot of the noisy bits, and the cupping directs the mid frequency speech, giving selective gain. And it works particularly well with those cheap top directed speakers.
@@twohandsandaradio Haven’t tried that. The electronic solutions are great, but sometimes simple acoustic techniques a can do wonders, and outdo the circuits.
I have terrible QRM (and QRN occasionally). When trying to listen to my nearly intelligible 10 local repeater, I found piping my receiver audio through my PC and using Nvidia Broadcast AI to filter out everything but the voice worked incredibly well. There is some occasional issues with it filtering out voices in the noise floor, necessitating some pre-eq filtering. But how it cleans up and eliminates noise is nothing like any notch filter can do. it seems to fill in the gaps as well, meaning words that otherwise would seem cut off are understandable.
I bet Bob would come to your shack and do a personal demonstration. That would make a great video. I can only judge the audio you produced based on the quality of the device I am listening to.
Newbie question - how would the Heil Parametric Audio System compare to the RigBlaster (DXPro).. would it compliment or be overkill ? Transceiver(s) using would be 9700 and 7300 with three SP-38 ICOM speakers. Thanks ahead for your thoughts
You always do an outstanding job. But what you did not cover was TX and RF. Serious problem with this unit. What are your thoughts. If I only listen they are outstanding. Try and Tx and the feed back is so bad. Crank up the amp and it is ridiculous. I have done everything. Was already CMC and torrid over kill. My head set put into either radio has no RF issues. My Yeasu Sp 102 also is clean on TX. Did you know Palomar Engineering sell a complete set of fair rites to supposedly fix the issue “ in most cases”. Reviews have show consistent issues with many sending them back. I have spent hours of frustration and money to use what I hoped to be an assumed great system. I would like to see it really work. This set is going back. I truly. Eli eve the shielding in the units are poor to none existent. The customer service is great. But that didn’t solve the issue.
Actually, it sounds no better than a Force 8 equalizer I got from Sam Ash music. And a lot more versatile. If you watch some of the YT hams from the UK, they use equalizers DX Commander Callan is big into EQ. But he is into music ... And I think music stores are a source for audio stuff for us. Cables. Jacks. Et. Al. My SA is 2 miles from the house. They know when I come in I am looking for items I can use for ham, and do not pressure me to buy. And a few know ICom radios are picky about mics.... Ans they realize for some items they are a local Radio Shack...
Boy, Josh, it really sounded a lot better. you were able to pull some of those signals out from the basement and make them readable. Thanks as usual.
Thank you!

It does seem to bring out tougher stations.

Noise reduction or noise direction. I use a 3" pvc elbow that works wonders to redirect the noise.

Indeed. Also the quality of my my mics and CZcams compression, or who knows what they are doing. It can be subjective.
I have one on my 7610. Enjoy the heck out of it.
You should do a test with a lesser receiver such as a 450d or ic-718 to see if there is a dramatic difference.
Got one and use with a JBL studio speaker. Best accessory I have ever bought. Amazing
Thanks for watching!
As my ears age and loose the highs, I can see where this can be useful.
Thanks for demo Josh. I notice you got your AGC set to Fast. Try it on Slow. I reckon it could enhance things further.

I was wondering how the PRASEQ would work with my Pro 7's. I have tinnitus and sometimes is still hard to pull voices out with the Pro 7.s
I should, it has a headphone and mic jack.
Wow could it just be the supplied speaker is a problem?
Is it an noise eliminator also
Wondering if it'll help CW

I thought I heard "Kennedy Steve".
Got me wondering if there is a software program optimized to achieve similar results if the audio was fed into a laptop instead.....?
There could be. But I am unaware.
I want to love this but I encounter massive RFI problems when I use the included power supplies. :( Pegs the S meter on S9
It doesn’t include a power supply.

I have the unit grounded. I don’t experience feedback. 🤷🏼♀️

Sorry totally missed the point. Too many audio changes, too quick to hear the difference.
keep your money in your pocket i have one and its a load of junk total waste of money
First off.. This isn't a review... Second off... I will be giving you my thoughts and experience...
Ok, sure. Gotcha.
Ok?
He doesn't say it's a review. He says it's a demonstration.
