Within a maze of cubicles at a Hughes Aircraft Co. Inside, Arnold Klayman has been playing with his invention, the AK The AK conjures up visions of a new assault rifle from a company whose reputation was built over four decades as a manufacturer of sophisticated weapons ranging from radar systems to missiles. It is a stereo component that deceives the human ear into hearing recorded sound in three dimensions, instead of the normal two.

My LED display wasn't looking right so I pulled it out of the system for a while to check things inside. While it was out of the system noticed that the K-horns were very flat sounding, there is a separate amplifier feeding the K-horns with another amplifier feeding the center channel, sub, and 7.
The Hughes AK feeds only the K-horns. After re-installing the AK the entire system came to life again, especially the lower end which is abolutely earth shattering.
After reading previous posts on other kinds of these units I have determined that nothing, abolutely nothing said on those posts applies to this unit. There is no noise, no hum, no distortion, and the filter button on the unit does not need to be utilized. This unit overshadows my RSW sub but without the sub the really low end is missed even though the AK is not in the sub circuit. The sub, the K-horns and the AK all act together to provide blistering low end. The snare drum hits rattle your stomach.
It has one board with about 30 Chips and one display unit. The diodes on the power supply section are huge and conventional needle nose probably would not bend the leads. They appear to be. I tried to pull off the ribbon cables but they were very difficult so I stopped for fear of pulling something apart.
They made this when they were making your father's Oldsmobile. Special RCA molded jack assemblies. The covers were made out of something called metal. No corrosion on any component. It also had a power transformer and a fuse. The things that these units are capable of amazes me! I could care less what others think. The Impact Restoration feature alone is worth using them.
I use them exclusively for my Sat Dish audio signals and boy what a difference! I have thought about trying a Hughes AK but haven't yet.
I have seen some nice boxed ones pass through eBay too. They had a later model but I don't think it was as good as the first version from what I hear.
If you are referring to something similar to a dbx 3bx, 4bx, 5bx, then shhhhhhhhhhhhhhhhhhhhhhhhh. Kind of makes your Khorn sound a bit like a transister radio impact wise when it's taken out huh? The hughes unit should be quiet, I have seen that unit in a recording studio.
I thought is was an ambiance processor, supposed to give a surround sound experience through two speakers since it is an SRS Sound Retrieval System processor. I found this quote on the web about the unit:.
The technology is now licensed to Sony and others who use it successfully in their products. This was Hughes top of the line unit. The basic idea of the device is that it attempts to detect and enhance difference L minus R information between stereo channels, and also to to detect direct vs.
It then allows the user to balance these parameters, offering as a result:. This is not a magic box, just an intelligent application of well-known acoustic principles. The effect is subtle but noticeable, and the unit can be used either to simply enhance stereo or as a pro studio signal processor. Has , center, space, and level controls. This is a cool image enhancer. For those of you who are familar with the Hughes Sound Retrieval System SRS know that it can make a 2 channel system holographic and provide a very deep and wide soundstage.
Quoted from Hughes' literature: "You can move anywhere in the listening room or rotate your head, because unlike other systems, there is no critical listening position to limit your location. Not sure of models, and to my knowledge I cannot recall having heard a system using this on satellite reception Also, of the audio versions, as it was mentioned that some of the later units are not as 'robust', which units model numbers are worthwhile and which are to be avoided?
And one more off the wall question Similar, better, worse?? I think that is what it was intended for originally, lend excitement and fullness of sound to lesser audio systems. It was also used by a bunch of FM stations. The effect is awsome on the low end, and while it is louder in volume the low end sound becomes huge.
With the unit out of the circuit I can crank up the volume but it is not even close to the low end impact when the unit is in the system, and that's only the two K-horns, not the center channel, not the sub, and not the other small side and rear speakers.
Volume itself does not duplicate what this unit does. I'm not sure how or what this unit does on the very high end as my hearing cuts off abruptly at Hopefully I can add something to this thread. Hughes only made 2 versions of this thing - the AK , and the later AK The rights to the technology were later sold, and a company called Nureality started putting out their version of the unit. Their first version was pretty good, but it did not include the filtering that was available on the AK which was extremely useful on some material.
Nureality then came out with very tiny units that were primarily intended for computer speakers. These worked pretty well, but they had far fewer adjustable parameters. An even later version just had an "effect on" switch, with no adjustability. From what I have been able to find, it looks like this last version was the version that was later licensed to Sony and others. The priniple problem with these later units was the cheaper build quality, and lack of adjustability.
I loved the SRS units yes, I had at least 5 versions of this thing , but they were at their best when used in moderation. A little went a long way in opening up the soundfield, especially on Heritage Klipsch. The original unit was the best because you could tailor the effect to the individual source material without too mutch tinkering.
The later units, without any adjustability to the effect, often went the overkill route because of their fixed effects. One of the nicest features on these units was the 3D mono effect. I found that this mode really did wonders with old mono movie soundtracks. It's the one thing I miss about having gone to the Harman Kardon "digital straightpath" receiver I am currently using. If anyone wants to fool around with this technology, the closest equivalent would be the SRS WowThing.
It is an updated version of the old SRS technology, in a very small unit. I've not listened to LP's without one in the system for 30 years. However, I just returned from a good friends home in Houston who had, at my suggestion, obtained a 1BX with Impact Restoration. Totally awesome. Only describable as having the silence, dynamic range, and impact of digital with everything you love about analog. While a music lover, my friend is no freak like us by any stretch.
He just looked at me and said "Yup, Dave, not even subtle is it? Dave, I assume you have the original 3BX with the wooden side panels. They come up pretty regularly on eBay. There were 4 versions of the 3BX, the original with the wooden side panels, the Series II which was made into single rack space size, the Series III this unit introduced the Impact Restoration circuit , and the final incarnation the "DS" Digital Series version which was refined for use with Digital sources.
The Digital Series unit is more refined and smoother sounding, it also has Impact restoration and an Ambience feature that allows you to trim or widen the soundstage. I am NOT an audiophile, but I have one of these units and am looking for a manual for it. Possible sale or I may keep it as a curiosity. Serial Number is: K I have not yet tries it out but appears to be in excellent condition. The black protective "Film". Thanks to those whoposted information.
It has been very difficult to find info about this. Thanks, Ken Pendarvis, kenp socal. It is definitely not marketed in the audiophile world and I was disappointed to learn that it doesn't support Asio, although maybe the newer version does. Interesting that this review related it to the Hughes unit. When I get some time I may play with it. After reading the input on this site, I recently purchased a Hughes AK Although it came with the manuals, I still am not sure that it is connected correctly.
I would like the Hughes to process all the various inputs, phono, FM, cassette, etc, in my system. In this configuration, the display lights rarely light and then do so faintly. The sound output is also dramatically reduced. Now, when I actually plug the Hughes into my Niles auxiliary input selector, the display seems to operate normally and the sound output is much higher. This configuration, means however that the Hughes does not process all the system inputs.
What am I doing wrong and how can I correct this? Is this preamp not compatible with the recommended Hughes configurations? If so, is it also incompatible with the Carver C9?

Log in or Sign up. Messages: I read the manual and I did what it said. And the lights on AK flash around. I can stick them on it put I can easily slide them off. Maybe that has something to do with it?

The dreams of yesterday To make the impossible possible. Widen the field beyond speakers. The job of an engineer. Whatever they were thinking it came together so well.
HUGHES AK-100 SOUND RETRIEVAL SYSTEM SRS
This unit is in great shape, and has no issues. Tchad Blake used this stereo widener on room sounds, and reverbs during mixing of the Black Keys "El Camino". It can create depth, and widen the stereo image. This process creates a more spacious ambience within the stereo field, producing strong special cues for different instruments in an audio mix. Now, unlike several other stereo enhancers, the AK does not have time delay processing, its Sound Retrieval System is single-ended, requiring no prior encoding of program sources.
