SeeKai Posted September 11, 2014 Report Share Posted September 11, 2014 [edited for clarity] Hi Guys, I am getting no love from the manufacturer or the distributor of the microphone, so I am forced to ask here. Has anyone successfully terminated an OST TL40 for Wisycom systems? My best guess would be to wire it for the "2 wire + bias" setting on the wisycom Tx, however I'm suffering a little bit of a mental block over the supply voltage available. The manufacturers spec lists the nominal supply voltage for the TL40 as 1.2volts, the wisy's offer 5.5volts - should I be looking to wire in a resistor or will the mic operate happily with a 5.5v supply? There is no maximum supply voltage offered by the OST on their website and they weren't willing to answer my question via email. I'd also like to terminate one for micron explorer which outputs 9v or 5 v for +ve and -ve bias mics respectively. Does anyone know if the TL40 will operate happily on these supply voltages? It seemed sensible to ask when the supply voltages involved are approx 4 and 7 times the listed nominal value. Quote Link to comment Share on other sites More sharing options...

SeeKai Posted September 12, 2014 Author Report Share Posted September 12, 2014 read the manual. page 12. http://goo.gl/AsYAJz Hi Miles, I've read the wisy manuals - that's the 2 wires+ bias wiring I was referring to in my post. I probably wasn't clear - I tend to ramble a bit! My main reason for being cautious about this is that the TL40 listed a nominal supply voltage of 1.2 volts - I want to be absolutely sure that feeding it 4 times (wisy) or 7 times (micron) this voltage is not going to result in damage to the mic or some other undesired effect. I know that we're dealing in very small voltages here so I'm perhaps being too cautious, but I wanted to seek advice nonetheless! Quote Link to comment Share on other sites More sharing options...
SeeKai Posted September 12, 2014 Author Report Share Posted September 12, 2014 OK for anyone who reads this at a later date: The max supply voltage of a TL40 is 5 volts, once i've done my sums I'll hopefully be able to confirm something that works wiring -wise and share it here.

SeeKai Posted September 12, 2014 Author Report Share Posted September 12, 2014 Thanks Mike! I think I'm going to work it all out just for fun, though I don't think wiring resistors into the locking three pin lemo is going to be any fun, so this may end up being a purely theoretical exercise.
