DCI Specialty ALH1

Adjustable Audio Hum Eliminator Testamonials

Over the years, we've received some very entertaining emails from customers. These emails were unsolicitated.

Just following up….I’m very happy with the ALHI. Here’s a testimonial in case you’re looking for any…

I had a significant hum problem after hooking up the TV in my bedroom to a cable box in another part of the house. I tried the Radio Shack isolator with no success (it didn’t remove the hum and made the sound worse). The ALHI, on the other hand, eliminated the hum while preserving the audio quality. Highly recommended!

Hi I work for Al.........
Al liked the first one. it has more of a crisp sound than using an iso max isolation trans. because u have a 100khz bandwidth!!!!!!!

Just received it and I hooked it up. Very easy hookup and to adjustment! It works!!!! Thanks alot. Great product. I will tell all my friends and also my son who is a computer tech who couldn't figure out the hum. Ground loop must be a very common problem with AC circuits. A very reasonable fix.

Again thanks, Steve L.

Hi, I received the ALH1 today and it solved my ‘buzz’ that existed between my Denon 3803 and Samson S1000 sub amp. I thought you might be interested in my thread on the Home Theater forum.

Thanks for offering a wonderful product and for the quick shipping. If I ever encounter someone with the ‘buzz’ I will send them your way.

Kind regards, John W.

Hello....just a big thank you for a superb product that really works!!! I have been having nothing but problems with a low frequency hum that I tried everything to get rid of with no success until your hum eliminator solved it! I have a very expensive high end home entertainment stereo system with a computer hooked up for playing my extensive list of albums or even online radio (anything from the net)....but had this pervasive low frequency hum that was present whether the volume was on a very low setting or on high....and with a quick adjustment of the dials on your unit, the hum was completely gone.

Thanks again for a superb product!

A very happy customer!!!!

Thank you for your product; it effectively eliminated the hum with little or no adjustment. I’m very satisfied and have told others about it.

Hi, I recently purchased an ALH1 for evaulation in my home system and so far I love it. I am also evaluating the Radio Shack 270-0054, and, based on my results so far, I think your stated specifications for the Radio Shack unit should be rechecked. You state it's response as 300-4,000hz ±3db. Using Stereophile's Test CD octave/decade test tones, I'm getting much wider bandwith than that, more closely resembling the full audio spectrum, e.g. 20-20khz (no specified ± db range). I think Radio Shack used to make a couple of isolators, and perhaps it's the other one that has the limited bandwith.

Just FYI...thanks...Dave

Note: Followup from Dave after reviewing Radio Shack's specifications-

Can't argue with their own specifications! Shows what can happen with a subjective (my listening results) versus objective evaluation.

Later...Dave

And one from someone that the ALH1 did NOT work for:

Hi, Got the new one, Still the same issue. It must be some kind of capability thing with my gear. I will send both back I greatly appreciate your time and great service. It is nice to see when someone stands behind their product with action and not just words. Thanks Don
