RoyS Posted March 17, 2010 Share Posted March 17, 2010 Hi All, I work In a venue that that always requires a fair bit of fault finding ahead of the gig. With this in mind I have various test gigs to help. I now want to put together a Speakon to headphone adaptor to test the output of an active monitor amp rack. Simply put, I want to connect the LF to one side and the HF to the other. Obviously I don’t plan to put large volumes though DT100 (or similar) cans, so would like to put in a simple sort of resistor arrangement (inside a connector if poss) to reduce the volume and help protect the cans.. Can anyone offer help here? All suggestions gratefully received… Cheers Guys.. Roy Link to comment Share on other sites More sharing options...
RGSD Posted March 17, 2010 Share Posted March 17, 2010 Buy a galaxy audio clicker - that will tell you if each speaker is in phase. Open up each speakon connector and check it is wired correctly..... I've always found that works. Link to comment Share on other sites More sharing options...
Wilflet Posted March 17, 2010 Share Posted March 17, 2010 If you have something to check the wedges themselves (ie a speakon to bare ends (each pair taped together into pairs labelled with number or frequency band) and a 9v battery - cheap and dam near idiot proof) by checking the speaker box, and cable run (test wedge down cable with barrell as needed) then youve already isolated the problem to the rack as everything after the rack works and you'll see signal lights on the processor and amp (at which point your down to volume knob on the amp or patching) without needing to have your headphones.I think your over complicating something that you can already do with equipment that either you already have or, if you are building up test gear, will have soon.

Brian Posted March 18, 2010 Share Posted March 18, 2010 Can anyone offer help here? All suggestions gratefully received…Hi Roy, the resistor values you need will depend on which version of the DT100s you have. They make them in different impedance values which, IIRC, are marked on the cans themselves. Or, as an idea, how about a little plastic box which goes in line to the cans with a volume control on it. With that you could adjust it if you were listening out for quiet signals on a noisy stage. It'd be easy to fit a basic limiter to protect the cans if the know was set to max.

RoyS Posted March 18, 2010 Author Share Posted March 18, 2010 Thanks for all the replys so far. The DT100 headphones in question are 16 ohm versions. The pot in box sounds good! Roy Link to comment Share on other sites More sharing options...
Sound Man Posted March 18, 2010 Share Posted March 18, 2010 Would this unit fit the bill? David Link to comment Share on other sites More sharing options...
RoyS Posted March 18, 2010 Author Share Posted March 18, 2010 Yes Soundman, it looks great. I wonder where I can get a circuit diagram from ;-) Link to comment Share on other sites More sharing options...
