    I'm having a hard time finding a Jensen TA-R1 online. Would the isolator purchased do the same thing?

    I thought you already stated that this did not solve the problem. It will not do the same thing. The dummy plugs are for testing to figure out what exactly the problem is. The TA-R1 is not exactly how Jensen makes its money at $10 a pop, so maybe calling them is the only way to get some. Or you can make your own, but the parts will probably cost more than $10.

    Quit bragging it's not nice, we all know California has great weather, no real summer or winter, right in the middle most of the time. But most people out there make up for it in strangeness, you seem normal how did that happen, your from somewhere else more normal, a little at least ? :huh2:

    Methinks you're thinking about the coast. Out here in the desert it gets friggin hot sometimes. And yea it does not get as cold in the winter as it does in Montana but if you were outside all night unprepared you could die of exposure. I did not mean it as a brag but just sharing with my C,C and C buds how grateful I am that its only 90 not 115☀️.

    And yea I'm just a man from Michigan.

    Jeesh, how complicated can it be:)? Marvel I really have no idea. I would assume if I ever get that far it would have to be something that runs on a Windows computer. Right now the mixer I have only has a firewire interface and therefore has never been hooked up to a computer. I am assuming if I really want to get involved with this the first step will be getting a new mixer with USB or AVB interface(s).

    My understanding of the 5bx is any signal over the threshold got left alone or compressed depending on the settings. It is not a linear expander but a downward expander and compressor combo. I have no experience with these units but that's my understanding. With compressed recordings I want linear expansion. If its too loud I can turn it down or use one of the compressors in my mixer.

    Mostly we use gates when needed.   I guess "on paper" I understand.   We had primarily used outboard gear in the past.   I mean for budget gear that "expands" my question is, do the pros really outweigh the cons in terms of SQ and SNR?  I kind of doubt it.   Hearing is believing I guess.   

    The effects are subtle but still audible. You can adjust the threshold way wrong and try to upward expand everything and the result is not good(to my ears). It also divides up the frequency of the signal into 3 bands and performs its magic on the 3 separately to avoid the lows effecting the highs and vice versa. As far "budget" is concerned this unit when in production had the best VCAs and RMS level detectors that DBX produced. i.e. the same ones that went in their studio gear. My modified units now have the best VCAs and level detectors made by THAT Corp. And IMHO the best audio Opamps ever made the LME49720.

    I owned one of the 4bx when they were first introduced and like you said I returned it 3 times to end themselves in the first year because the intermittent locking up remote board issues but they finally seemed to have solved it since I didn’t experience any more issues until I sold my whole system to a friend several years later and headed a different direction with my audio at the time.

    The problem that I experienced (and the problem the guy in Australia) fixed was under compact florescent lighting(maybe LED also?)  the remote just did not work at all. All is well now. I should post pictures of the old circa 1978 technology board and the new one now that they're both out of the units and available.

    It increases the dynamic range of the compressed signal that you get on most LPs and CDs. It has an adjustable expansion ratio from 1.0 to 1 up to 1.5 to 1 so nothing crazy. It also has an adjustable threshold so that signal above the threshold are given gain and below threshold are attenuated. In effect it makes louder passages louder and softer ones softer. Granted if you have a great recording it effects are not needed. In a studio I believe expanders are used for downward expansion only. I looked briefly for a expander plug in for a DAW that was not just downward expansion and came up empty. If you know of one please post a link.
