Finbar Posted May 26, 2008 Share Posted May 26, 2008 I saw someone with a Hiwatt 400 valve head at a show once, which had 4 inputs. He had a short patch lead connecting two of these. Just wondering what this was in aid of? Sorry if it is painfully obvious, I was just intrigued Quote Link to comment Share on other sites More sharing options...

Finbar Posted May 27, 2008 Author Share Posted May 27, 2008 Ah, I see. What's the science behind this then, if all of them are inputs, and none are ouputs? Quote Link to comment Share on other sites More sharing options...
Hamster Posted May 27, 2008 Share Posted May 27, 2008 I don't know that particular amp, but on the early Marshall non master volume amps it was just a way to use the volume control on each channel to produce a wider range of tone.

Finbar Posted May 27, 2008 Author Share Posted May 27, 2008 As far as I know, the Hiwatt has a master volume, and only one channel. Quote Link to comment Share on other sites More sharing options...
Tengu Posted May 27, 2008 Share Posted May 27, 2008 Are you sure that they were all inputs? I have a Peavey CS800S power amp. This has stereo inputs plus an output on each channel. That enables you to patch the input on channel A into channel B, essentially turning it into a mono amp with double the output. I suppose you could also send the signal from both channels to another power amp if you wanted extra stereo power. Quote Link to comment Share on other sites More sharing options...
Finbar Posted May 27, 2008 Author Share Posted May 27, 2008 Off the top of my head, the Hiwatt has 2 'normal inputs' and 2 'brilliant inputs'. Someone should be able to confirm that for me? Quote Link to comment Share on other sites More sharing options...
BigRedX Posted May 27, 2008 Share Posted May 27, 2008 On this kind of amp each pair of inputs has a slightly different tonal characteristic. Using a patch lead in this way is effectively the same as connecting to both with a splitter cable. If the pairs are Normal and Bright running both together gives you both tonal characters together - you get the increased top end of the bright channel with the normal channel adding a bit more body than just running into the bright on its own.
