Oohhh, what does this do? (New Amp)

Recommended Posts

Alrightey, I finally picked up my amp (Crate BFX100) but am having many problems understand all these knob thingys all over the hot sweetness! So could someone please explain to me a few things?

 

-15db push-in button by input: What does this do exactly? I know that it makes the volume go down, but that's absolutely it.

 

Peak light next to gain control: I have no idea what this does either. It usually flashes once per note that I play.

 

Contour knob: No idea... either. I currently just leave it in the middle, but there's no effect that I see.

 

Active push-in button next to Contour knob: What does this do? I think it makes everything louder, but not sure.

 

Limit light next to Master volume knob: I think this tells me when I'm hurting the speaker. Is it extremely unsafe to play with this light on? I don't want to hurt my speaker, but it doesn't play too loud (or loud as I'll be wanting it to play later) without the damn light coming. I really need some info on this one.

 

And now for a few more amp related questions.

 

What exactly is the difference between Gain and Master volume knobs? I know distorted guitars the crave Gain, but what EXACTLY is the difference?

 

There's a speaker input thing on my amp. Does that mean I can hook my 15 watt, 1x10 amp up to that and get a little more umph?

 

Any other good tips for getting the most out of my amp?

 

Thanks for tolerating my very questioning mind and for your time.

That's to lower the input if you're using an active bass, so you don't overdrive the preamp.

That tells you when you're overdriving the preamp. Hit the -15dB button and the light should stop.

EQ setting for more high end or more low end I believe. Don't quote me on this one.

Doesn't make sense to me.

Hmm... :confused:

Gain is the input to the preamp, volume is the output to the speaker.

Sounds like it should be a speaker OUTput for an extension cabinet. Get back to me on this one.

Nope, play with the EQ 'til you get something that sounds good. And add some bass for it to sound louder. If you're not getting enough umpf, try playing with the knobs on your bass :D

No problem. You can email me the required funds via PayPal. :D

ok i had one of these...

 

READ THE DAMN MANUAL!!!! THAT TELLS YOU EVERYTHING!!! lol :D

 

The gain should be always set at about 1-2. Leave it at -15db on anybass. The contour knob (theres a button that activates it next to it) all the way left cuts highs and boosts lows, mid position is pretty much flat, and all the way left cuts lows and boosts highs.

 

BUT READ THE MANUAL AND SCHEMATICS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The limit light is probably telling you when the limiter is kicking in, smoothing out the peaks. It tells you that you would have been hurting your amp, except the limiter did its job.

I had one of these briefly. The limit lite shouldn't stay on- its ok if its flashing occasionally. Is your bass active or passive? If its active you may want to cut your gain. My Fender (passive) liked the gain about 10 o'clock. start with the countour at 12 o'clock and the eq flat. Also use a long cord and stand out in front of your amp so all the sound isn't going to your knees. This amp should be loud enough for most applications and if I remember right it has a line out to the PA. What are your Guitar players using?

Thank for the help. My best friend has a Peavey 1x12, don't know the wattage. After Church I'll try to find a match on the web. I'm talking to the other guitarist at church today, so I'll give you details on that stuff in a few hours.

 

So it's alright if the limiter is on? Not a great thing, but ok?

Check the makers web site they usually have an idea, or a really sneaky thing to do would be to go into a shop and try out one and ask for an explanation or a look at the manual he he.

No. These controls exist to bring the level of your bass up to line level - depending on your pickups and electronics the amount of gain required will vary. The -15dB pad is there in case you have an active bass with a particularly hot output. The gain control should be turned up until the peak light flashes on your loudest notes and then turned back down a smidgen. If your bass is so loud that you have to have the gain control down near zero then try engaging the pad whic should let you turn the knob up further without clipping.

 

If you use drastic EQ you may notice the preamp distorting even though your gain was set correctly (the clip light may or may not flash depending on where it meters the level). If this happens, turn the gain down.
