    Question????

    You say your running mono blocks "right?" before you had the AI-1 SDA IC, did you have these amps strapped?? if so when you hooked up the AI-1 SDA IC did you unstrap them??

    If you have the 1.2's, and I'm guessing you do then the AI-1 cable should work.

    He has original SRS's.

    Again he does not have the original SRS's.
    He has the pin blade, and he has 6511's and 6503's.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    Ben, I'm simply going by what Polkclyde provided as info. His posts are a bit ragged and hard to understand at times. Pics would certainly help get a much better diagnosis of the problem.

    My rec was made based on the info he provided.

    Well you've been around here long enough to know what a mess some of the SDA models can be especially some of the transitional models. Hopefully when Ted comes over he can help you sort it out.

    I will look in my compendium tonight and see if I can shed some more light on the subject. Perhaps the AI-1 is at fault, probably not very likely, but you never know.

    So just to be crystal clear, you have SRS's w/Pin-Blade? Or are they actually SRS 1.2's? Maybe you're not sure???? The compendium will help now that I know what drivers you have and that it's Pin-blade.

    It's real easy to figure out what driver you need, just use an ohm meter

    MW6503 will be around 8 Ohms and a MW6511 will be around 4 Ohms,

    Hope this helps.

    Without a doubt, your speakers are 1.2's as others have noted because they have the pin/blade interconnect. There is no such thing as an original SRS that has a pin/blade IC as far as I know.

    Note that the sticker seen in photo #4 is for the original SRS (blade/blade IC). They were manufactured with the positive binding post on the right and negative on the left. The 1.2 and 1.2 TL's binding posts are wired just the opposite. It's good to see that your speakers have the red binding post nut on the left and the black on the right as they should be.

    Your 1.2's can be converted to TL's by making the required changes to the crossovers, reversing the polarity of the tweeters at the molex connector and changing the white wire at the tweeter to a larger connection to accomodate the SL3000 (or RDO-198) tweeter.

    The TL mod requires that you mod the inductors, or find some with the right DCR.

    wow,That's out of my league.I'll have to talk to Ben,about that.I am not going to touch those crossovers, without assistance. Thanks.

    I have been using mono amps,The carver silver 7t mono amps,to be exact,since 1990,without any real issues.The Sales person at Sound Advice told me to tie or connect,with a wire, the negative,to negative post together,and everything would be fine,he was right,no problems.The Problems is with me,most of the time.What happen yesterday is the left mono bloc amp wire came loose.then, I thought the AI-1 cable damage my Amp,thank God it didn't.

    Since you have strapped the negative terminals together without issue(ie.blown output transistors) that indicates your amps do not use a bridged output stage thus even though in separate chassis's can be made common ground by strapping.(this also applies to other mono blocs that don''t have bridged/balanced output stages).


    Correct me if I'm wrong but it is my understanding that the A1 cable is only for use with non common ground amplifiers.If thats the case then with his amplifiers being common ground when strapped would make the A1 cable unnecessary.

    One can use the AI-1 with common ground amps without any issues, althought it is not needed.

    Using the AI-1 instead of strapping the grounds will result in improved sound.

    That's why I decided to get the AI-1 Cable,for improved sound,not that my system doesn't sounds awesome,now. Maybe, I have a fautly A1 cable.you guys think it safe for me to try and connect it again?
