thunderider Posted June 26, 2012 Share Posted June 26, 2012 (edited) ive just got a marshall head,but its giving me headache....on the back there is standard 2 outputs!! but theres a switch for 8Ohm and 16(4) Ohm i t ake it the 16(4) is to plug a 4x cab in,so i gather i cant use a single 4Ohm cab? also if use 2 cabs how would this break down between the 2 inputs?...im all ohms lawed out!!!

Mr. Foxen Posted June 26, 2012 Share Posted June 26, 2012 What do you mean by 16 (4)? Quote Link to comment Share on other sites More sharing options...

1970 Posted June 29, 2012 Share Posted June 29, 2012 (edited) manual : [url="http://www.marshallamps.com/product.asp?productCode=4100&pageType=DOWNLOADS"]http://www.marshalla...eType=DOWNLOADS[/url] It's 8 or 16 Ohm only: [i]Impedance Selector Switch: Two-way switch for matching the amplifier to speaker impedance. Amp heads feature 8 or 16 Ohm operation. Combo versions feature 4 or 8 Ohm options.[/i] Guessing they used the same backplate on the combos as the heads. So nope you can't use a 4Ohm cab with this one. If you wanted to use 2 cabs they would have to be 16Ohms each, and you would set the switch to 8Ohms.
