hey

i have an ashdown MAG combo, and i saw that it has two knobs on each side, 1 called input and 1 called output

when i put either higher it goes louder

my question is which 1 should i be puttin higher, like should i keep the input at 12 oclock and then change the output or vice versa

also does it make any difference?

i don't really know, but at a guess is one for adjusting how loud the signal from the instrument is going into the amp, and then the other controls the signal out of the amp.....wtf, does that even make sense???



i think thats what you mean and thx but what im asking is whats the difference with turning the input up instead of the output or vice versa?

if that's what they do, then if the input of the instrument is too high, it will distort cos the signal will be too strong, but if you have a bass with a crap signal you can turn the input up to
compensate for it, or if it is active you can turn the signal down. And the other just seems like what you'd do with a normal gain control. so distortion or not.

ok thanks so much for that

it also makes a lot more sense than ur previous post

What you do is you keep the output at 0.

Then you turn the input up until you're in the perfect spot for it - it should say on a threshold meter or VU Meter or something.

Then, you turn up the volume until you get to the desired volume.

Looks like you want it about 3 on the VU. Take a look in the manual though, might tell you there.

Are you putting it into the right input? One is for passive instruments, the other for actives.

See which one puts your bass at a higher input level.

Oh, okay.

Um... I guess that's normal then. I'm not sure what to say now.

Enjoy?

As long as it's loud, I guess it doesn't matter lol.

I find on my MAG that the input makes a difference to the tone - the EQ is more effective with a higher input level and even with the EQ bypassed it sounds a bit beefier with higher input.
#15
sorry for the double post but...

hey nutter i figured out what i was doing wrong

i had the volume knob on the bass turned down so that when i turned it back up again the meter went higher

just thought ud like to know

I wouldn't rely too much on the vu meter - it's not that accurate and your ears are a better judge of when you've got it too high.

i find the VU meter extrememly helpful, i have my needle right before it goes into the red area to give some nice punch.

1 last question

It's an octave effect. Press the button and turn the knob up and turn the bass up on the EQ and you should hear what it does.

Youre supposed to have it so when you pluck the strings in your normal way, the needle pings to the 0(just before the red bit), it's about 2 o clock for me but it'll change depending on your technique.

This feeds the correct supply of power to the preamp to keep it beefy but not distorting! You may want to set the input level lower than it should, so when you play a peice with higher dynamics, it doesnt clip.

Preamp distortion is not nice.

Then you set the EQ to how you want.

Then you set the output level to what is required.

If you want a good analogy, imagine the amp is a car/motorbike. To get the best performance (not economically), you want to keep the revs high, this is where all the power is. If the revs are low, it wont pull as much as when theyre near the red line. Go over the red line and you can **** your engine over.

I've got the same amp and I have a question. How do I get the VU meter to move? I'm playing a Passive Squier Jazz bass and I'm using the correct input, when I turn the input knob it doesn't move at all. I can't get it past -20, and it's supposed to be at 0.

there is a EQ in out button, check if thats in, if it is then boost some of the frequencies.

you have to play as well.

the needle will only move when you play.

if the needle doesnt move, and you get no sounds from the amp, check the volume on the bass.

if the needle doesnt move, but you hear sounds from the amp when you play, your VU meter is broke.

This is a very helpful thread, I have to use an ashdown sometimes at the rehearsal rooms I go to and I only had a vague idea of what either knob would do.

Looks like my VU meter is broken. Awesome. Is it a big deal or is it something that I absolutely have to get fixed?

It's not a deal at all, just asthetically something annoying. If its still under warrenty, take it in for repairs.

You'll have to set your input level by using your ear.

Turn the input knob up a little then play, then turn it up a little more. Repeat until it starts to distort. When it starts to distort, turn the input knob down a tad and you'll be set.
