Papabull Posted April 3, 2014 Share Posted April 3, 2014 Hi I'd be really grateful if any one can tell me if i can use a standard BOSS power supply on my LINE 6 G50 wireless receiver…. For the techies out there the LINE 6 is 9V at 500ma Any help gratefully received Cheers Quote Link to comment Share on other sites More sharing options...
ahpook Posted April 3, 2014 Share Posted April 3, 2014 Which Boss PSU are you intending to use ? Quote Link to comment Share on other sites More sharing options...
Papabull Posted April 3, 2014 Author Share Posted April 3, 2014 its a standard Boss Pedal PSU…. Quote Link to comment Share on other sites More sharing options...
dudewheresmybass Posted April 3, 2014 Share Posted April 3, 2014 If it is capable of powering a standard boss compact pedal, then yes Quote Link to comment Share on other sites More sharing options...
ahpook Posted April 3, 2014 Share Posted April 3, 2014 The Boss PSA 230S produces 500mA @9v, so it [i]should[/i] be OK, assuming the plug matches the socket and the unit's happy being fed by a switched-mode power supply Quote Link to comment Share on other sites More sharing options...

icastle Posted April 3, 2014 Share Posted April 3, 2014 Well Boss pedals are negative tip, so the polarity is OK for the G50 and looking at the G50 manual it shows it as needing 300mA. If it fits, it should work. EDIT: But you already know that because you tried it out while I was typing. Quote Link to comment Share on other sites More sharing options...
Dave_the_bass Posted October 20, 2014 Share Posted October 20, 2014 To take this query a little further: The line 6 power supply has a plastic lump between the transformer and the tip. Does anyone know what this is? Main reason for asking is that I'm planning my new pedal board and looking at potential power supply options and didn't know if losing this plastic lump might cause issues?

[/quote] That seems more than logical. I did wonder if it was some form of noise suppressor as I remember helping my dad fit something similar on an old car to prevent the alternator from interfering with the radio. With my rudimentary understanding of such things; if I place the new power supply as close as possible to the G50 receiver and keep the power cable as short as possible then I should notice no detrimental effects?

[/quote] Short cables help, and you can wind the power cable through a ferrite choke like this to help supress noise. They're not as good as the wired-in type, but they will help somewhat.

Dave_the_bass Posted October 20, 2014 Share Posted October 20, 2014 Thanks for your help. I feel educated and better placed to tackle my new pedal board. I just need my Christmas presents to arrive so I can start figuring out size/layout. Quote Link to comment Share on other sites More sharing options...

[/quote] Switching PSUs can cause noise through conduction down the cable (which the ferrite filter should reduce) or by radiation through the air (which the filter won't affect), so placing the PSU as close as possible to other devices might actually increase any interference problems. It's not easy to predict the effects of such things because it can depend on the amount of interference generated by one device and the susceptibility to that interference by another device. This sort of thing all comes under the general heading of 'EMC' (Electro Magnetic Compatibility) and there are various international standards to limit both the emission of such interference and the susceptibility to it - the basic idea being that devices should emit less interference than they are susceptible to, so that everything is compatible. It mostly works, but not always. The fact that the PSU has a ferrite filter suggests that it would fail the conducted emissions test without it, but that doesn't automatically mean it will cause a problem when it is removed because that will depend on the device it is powering. In short, the only way to be certain is to try it and see what happens. Quote Link to comment Share on other sites More sharing options...
