    3 Pin XLR headphone plug - wiring pin out

      Quote:   Oops, sorry about wrong info about combo connectors. By the way, combo connector (NCJ6FI-S) has gold plated XLR contacts, TRS contacts are not gold plated (at least solder end). -- het.s

    3 Pin XLR headphone plug - wiring pin out

    The pinout to connect stereo using single 3pin XLR (I do use single XLR for single-ended stereo signal) is taken from neutrik combo connector, where pin 1 = S, 2 = R and 3 = T. So when there's no standard it is good idea to follow this setup (as pins are hardwired inside neutrik combo connector...

    Can I use the iPod USB data transfer cable for my LOD?

    I guess not. USB cables have usually 4 wires: power + and - and USB data + nad -. Some dock connectors have only contacts needed for these 4 signals and others left out. You can buy cheap (and maybe better) dock connectors from ridax.se or qables. -- het.s

    Shippipng to europe

    It's different in every country I guess, but here in Czech Republic it is now 20 % VAT plus 3.5 % tax. It applies to shipments over 100-150 USD including shipping. If there is Digikey branch in your country you might get better prices without taxes. (It seems there is: http://www.digikey.it/...

    3 Pin XLR headphone plug - wiring pin out

    XLR Pin 3 (equals TRS stereo jack Tip) is Left channel, Pin 2 (TRS Ring) is Right channel and Pin 1 (TRS Sleeve) = signal ground. I like Nikongod's explanation about not connecting cable shield at input to signal ground but is every audio equipment producer reading this? :-) -- het.s

    How do you shrink your heatshrink?

    This tool:   http://www.dealextreme.com/details.dx/sku.1320   works faster than BIC lighters and is convenient to use. It gets pretty hot so I use supplied stand to cool it down after use. You can refill it with gas same way as cigarette butane lighter. -- het.s

    Exchanging plug on HD 555 (1/4" to 1/8")

    There are two wires for each driver. Positive and negative for each channel. You solder: *two negative wires together (they might be same colour or looking the same) at Sleeve of the TRS jack, *right positive (usually red) to Ring and *left positive (white or black) to Tip.   Or take...

    My previous post was unclear: I ment to put buffer inside LOD which is then connected to standalone portabe amplifier. So it's more kind of line-level buffer than headphone buffer. I don't think that current drain is big issue, maybe you lower your mileage to 50 %. I need amplification...

    thanks, now that you don't have to squeeze the caps inside LOD connector, you can put there (for portable use) opamp buffer circuit and use 3v or 3.3V directly from iPod (not tested). anyone to design such circuit? maybe only one dual opamp and passive components, or one opamp for buffer and...

    These three components block DC (solo capacitor is OK for this), avoid pops when switching inputs on line stage, stabilize signal and are there for safety. It works for me & my next stage. High pass filter is kind of side effect (it's not needed) and it is circa 0.4Hz. For modding 3G - I think...
