Bass Knob Issue

Recommended Posts

Sup SQ Forum,

 

So the problem: 

I re-tuned my amp with my knob and for some reason now on certain songs, I can turn the knob all the way up to the max without the clipping light coming on. (Didn't happen before)

 

Before: I had my 750.1 and HDS212 hooked up, tuned the amp with a youtube video on my phone with a 40hz note (Gain) and 100hz note (LPF) using my knob's (Set to half way) clipping light to set everything. Never had the problem

 

Now: Same 750.1 but now hooked up my new HDS312. Also, this time I downloaded and used a cd with a 40hz note and 100hz note. Same way, Bass Knob set to halfway and adjusted everything until the clipping light came on. But now I can turn it up to max on certain songs with the light coming on. (Just seems weird to me) Other songs, I use the knob normally, adjusting until the light doesn't completely or partially come on.

 

I believe I actually had this problem before with my HDS212 but I fixed it somehow. (At first I set the HDS312 LPF to 80hz, but then I remember SQ suggests 100-120. I thought setting it to 100hz would fix it but it didn't)

I also thought that maybe I had to reset the knob somehow as if it kept the same gain setting as the HDS212 with youtube videos. I don't how or what to do but I tried unhooking everything as if it was like a reset.

 

Any other suggestions, info, or similar cases from anyone??

 

Thanks ahead of time!

You're supposed to set the gain with the knob turned all the way up.

So how should I correctly do it? Disconnect my amp completely, reconnect, plug the knob in and turn it up all the way. play the 40hz cd track and turn the gain all the way up until the light comes on?

Don't trust a clip light.

Scope it, or set it by ear. When you turn up the gain and it doesn't get louder *or sounds harsh and odd*, that's clipping. Back it down til it's clean again, and you're good to go.

Yikes.  You got one part right.  The clipping light is most likely useless.

 

The rest, no.  Ok, the part about the ear sure.  Use it, when it starts to sound worse/stressed/wrong you went too far.

I've had amps do both, I just don't go past where it stops getting louder. It's the same stopping point, too much past that point is distortion.

That is not the point of distortion.  Listen more, believe the internet less!

Someone please just phrase it properly for OP. I know how to set a gain but, clearly don't know how to put it into words -.-

It was already phrased properly by ///M5. Hate to say it but maybe you don't know how to set one or think your way is correct. There is nothing wrong with learning something new everyday.

Is there any other number other than 1 or 2 that can be added or multipled buy itself, and still come to the same answer? I love math problems, and am obsess until I know an absolute. Any of you guys have an educated guess? Or atleast a college try?

So I see things got a little out of hand here lol. I still can't see if I solved my issue until my adapters from Knukonceptz comes in but I'm hoping setting the knowledge to make and adjust the gain will fix it. But I'm doubting it will, I never had an issue setting the gain with the knowledge halfway until now.

Sure sounds like a gain setting problem.  Possibly hardware issue, but your methodology can surely lead to the problem you are experiencing.

From my understanding the best and safest way is to set gain on amp all the way down plug in remote and turn the remote all the way up. Then use a multimeter (lots of tutorials on YouTube) if you don't have a dd1 and play a test tone on repeat and adjust the remote gain on the amp until you reach your desired voltage as derived from an equation that escapes me at the moment but should be in the video. This way you can't set your gains above where they should be and the remote knob will allow you to turn it down but not above where it should be

The DD1 is ABSOLUTELY the STUPIDEST way to set gain on your amplifier.

Amusingly the second is a DMM.

Do not suggest the DD1 to anyone please.  It has been a terrible tool for speaker manufacturers due to having to deal with blown subs due to .

The way you phrased it seemed odd to me, you said it lights up on some songs but not others. To me it sounds perfectly normal, every song has a different level that its recorded at. some will be at -2db, some will be at -36db. If your want to you can set your gain high enough that you can use the bass knob to get to clipping on all the songs you listen to. I find my bassknobs to be very accurate, but I cant say for other amps (crescendo 3500s) if you play bass kicks with definite clipping and without clipping you can train your ear very easily to hear the clipping at all times. Once you know what distortion really sounds like, it will be obvious and you wont even need a clip light.

 

I know someone is going to have an issue with what I said but everyone has there opinions and this is mine. hope it helps.

Then how do you suggest

I suggest putting pieces of tape over that bright ass blue light and that flashing red light. Just use your 5 senses.. Unless you listen to one song repeatedly then that stupid little light will drive u nuts.

Edit.. Except taste.. Unless you get down like that. Lol

This is my thinking process. I think I just have to turn up the amp a little and allow the know to be more adjustable to every song, instead of the max setting on certain songs
