[quote name='BeLow' post='237688' date='Jul 11 2008, 10:56 PM']If you have got a camera and can post some pics that would be good working on some very old memory I think what the controls will do are:-
2 x Inputs - hi/low (would that be active/passive?) - Yes that's about right
Gain (i know this increases the bass but why/how?) - what you need is a good healthy signal from your bass going into the front end of the amp, so I generally turn up the gain until either you hear it start distorting or a peak light starts flashing, at this point then turn it back a smidge. Too much signal into the amp will give a distorted sound, too little means that that you have to turn the master volume up more and any unwanted noise from your bass is more noticeable in the end output signal.
Compressor (no ideas what this does) - This processor is designed to stop peak outputs from overdriving the amp, it will also increase the lower leve inputs. This means that generally that you can play a bit louder without the amp losing it on loud passages. Some are good some are not - perosnal preference thing.
5 pre-set soundshaper presets one of them being EQ (which im guessing relates to the 7 slider graphic eq next to it?) - yep that sounds right in terms of the eq switch. I think the others gave a boost to the low end and the high end. Not sure about the others but it might be a contour switch which cuts mid frequency - which tends to work with slap or pick sounds. Essentially the switches should allow you to modify the sound quickly, then use the graphic to fine tune - best to experiment with what you like.
Master (master volume?) - yep
bi-amp (for attaching another amp?) bi amp will probablt split the high and low frequency part of your sound, it might be that you can route the the high frequency signal back through the combo nd the low end through a slave amp and bigger cab - say a 1x15.
and the standby switch - generally this allows you to mute the sound of the amp when you turn it on which can avoid some fo the dramatic thumps.
and on the back there is:
Loud Speaker Output - Minimum 8ohm load (?) to connect an extension cab of at least 8ohm or more
2xEffects Loop - send/recieve (?) - you can use this to add effects after the eq which shoudl be quieter
Mixer/Slave (?) connects to a mixer or slave to give you more oomph at gigs.
It is coming back to me now - I liked the idea of this combo - use it on its own for practices and quiet gigs and with the extension cab to give extra volume and better bass response.[/quote]
Thats great information again BeLow, thanks. It sounds like ive got a pretty capable combo for what im gonna be initially using it for which is learning in my room, and maybe eventually a bit of jamming with mates (although it wont be light to carry around).
I think i get what everything does now but i'll post a pic up as soon as i get a second to take one.
Thanks again.
