DEQ2496 Help.

I recently replaced my BFD with the DEQ2496, mainly for cosmetic reasons, and I just have a few questions maybe you guys can help me with.

When you set up the BFD the first thing that you do is set the input level. Does anyone know how to do this with the DEQ2496? The Level Meter on the left barely registers any signal, unlike the BFD, which would sometimes be clipping with the same input. I know the voltage is different but...

Also, I want to use the PEQ on the 2496 right?

It may or may not have a switch like the BFD has.

I have two peices of Behringer gear, the BFD and a Ultrabass Pro. The UBP does not have any sort of toggle to select the correct input level. With that device, I simply had to drive it with as much signal as I could.

IIRC, there are interface boxes that will match pro gear with consumer stuff. Hopefully someone else will chime in, but I think you would be able to find such a device at a place that handles pro sound.

Sorry for the confusion. It does have a voltage switch. +12v or +22v. I selected the 12v.

The thing I'm talking about is this: With the BFD you had you to hold the I/O button until it was flashing so that you were in Bypass mode. Then you had to set the receiver sub volume, by playing a bass heavy movie for instance, until the LEDs would go red or show that the sub was clipping.

With the DEQ, I'm unaware of how to do this. If someone knows how I would appreciate the help.

Thanks.

LOL!

I first thought that you were talking about the overall procedure, then I thought it must be that it lacks the requisite switch.

Well, can't help you there. It is quite possible that the DEQ does not have a seperate input/output level feature like the BFD. My UBP does not.

As such, you simply adjust the output of the pre/pro or AVR so that the input LED indicates that the input signal is at the appropriate level.

Hopefully a DEQ owner can confirm.

Thanks Brian. With the UBP, your not worried that your overdriving the sub, or something like that.

What I mean is. If I have to turn the bass up on my receiver in order to get the requisite signal, that means I have to drive my sub harder than with the BFD, because it's already at BFD max level.

I'm not familiar with all these things but I'm assuming its more strain on the amp as well.

Correct me if I'm wrong.

Well, I don't think you need to worry about overdriving the sub. If you need to run the level up on your AVR or pre/pro (as we do with a BFD), you would simply dial it back at the sub amp to compensate.

I know that there is some concern that you don't want to run the sub level up too high on the pre/pro or AVR due to distortion concerns (I think it was Edward JM, the HTF resident sub expert suggests keeping it at about -5), but I can say that with the products I have used, I have never noticed any issue with that.

Again, without first hand experience with the DEQ I can only speculate, but I think the trick is to feed it with enough signal so that its operating correctly and has a good S/N ratio, and then adjust the sub amp to compensate for whatever you need to send to the EQ.

OKay. So turning up the sub amp is not a bad thing then?

I don't know why but I always got this feeling that I should try to get the most out of the sub w/o turning it up too much.

I'll just do that then (turn up the gain). I appreciate your replys.

Well, in my case, since I had to boost the output of my AVR a tad to give the BFD a better signal to work with, I then found I actually had to drop the level on the sub amp a bit to compensate.

I suppose at the end of the day, its a zero sum kind of deal, so long as you are not boosting the signal at any point in the signal path to the point of distortion.

Hi Ainsworth,

If you want to get the best out of the DEQ you will need to up the level of the signal going into it, and yes the meter does show the input level, I mainly use the one on the LCD screen as it has peak reading so when I set the input levels I increase them until clipping occurs and then back it off, the amp is set a reference for this test, subs are muted of course. The closed I have ever listened to reference is -5 most of mine is between -20 & -15.

Now regarding the input level you do realise that as you increase the input level you need to attenuate the output, most plate amps don't have this type of attenuation available.

I am using a MX882 on both inputs & outputs and it does the job for me, there are a variety of other devices including DIY to do the same job.

Here is a post I did on the MX882 if you are interested.

Thats a cool piece of kit there, Richard. I am continuously amazed at the stuff Behringer has, and how little it costs.

5 subs? And I though I was a bad-ass experimenting with 2!

Cheers,

Hi Richard. Thanks for your response. I've been lurking these forums for awhile as well as the AVS and I always like to read your posts as their usually informative.

When you say you use the LCD, does the LCD show you that it clips. Does it say "Clip" for instance.


Sorry to sound ignorant but I don't quite understand this part. How do you set the amp to reference? Are you talking about using the AVIA disc to set the sub to reference?


I'm sorry. I don't understand this as well.

Since you are familiar with the DEQ, could you give me a brief synopsis on how to set up the DEQ so that it's being used like the BFD, or could you point me to any materials/thread that might help?
