weetoonhunter Posted November 16, 2010 Share Posted November 16, 2010 Hi guys first ever post I don't have a pad on my old a&h GL3 desk and I'm getting strong signals when I have overs on a drum kit. Is there any way I can pad these down?? All help much appreciated Jamie Link to comment Share on other sites More sharing options...
Russ83 Posted November 17, 2010 Share Posted November 17, 2010 Have a search for inline attenuator, there are quite a few out there. Here for example. Link to comment Share on other sites More sharing options...
paulears Posted November 17, 2010 Share Posted November 17, 2010 I don't think the Studiospares ones have 48V passthrough? This ones does, but is expensive.This one's a bit cheaper Link to comment Share on other sites More sharing options...
Pyramid Posted November 17, 2010 Share Posted November 17, 2010 You can just leave mic plugged in XLR input and select 'line'This attenuates the signal, don't remember how much, same/similar to a 'pad' on other desks. Link to comment Share on other sites More sharing options...

Yes, a quick check in the manual confirms that it's a -20dBu pad when you select "line". You have to go all the way to the schematic on p10 to find this out, though, it's not explained in the main section on the chanel strip. Link to comment Share on other sites More sharing options...
ramdram Posted November 18, 2010 Share Posted November 18, 2010 Whilst on the subject... If you need to pad an o/p down to I/p on an amp you can use a simple voltage divider. (I needed to take the o/p of a Nu-Mark CD player down to the input of a spare Kustom guitar amp for rehearsals (we made do with Mono of course)...two resistors worked a treat...still in use today as we found it was a lot easier than setting up the main amps.) See here for calcs: http://www.raltron.com/cust/tools/voltage_divider.asp http://www.electronics2000.co.uk/calc/pote...-calculator.php http://hyperphysics.phy-astr.gsu.edu/hbase...ric/voldiv.html http://www.sengpielaudio.com/Calculations03.htm www.communitypro.com/files/literature/.../PADS_CALC_TECH.pdf You can stick the Rs anywhere convenient on the front end of the amp I/p, or as some folk do, cobble up a lead(s) and use that. I suppose you could build a whole range of leads with different value pads if you needed a "Get -out-of-a-hole-card" in an emergency...Pad at the receiving end of the lead.
