behringer ep4000 mode switches

On the mode switches on the back, the ones for input 1 and 2 are reversed. Are these correct or is the diagram backwards and on is on the right and off is on the left. There seems to be quite a few threads on the hometheatershack forum with regards to this.

Mine seems to be working as expected with the dip switches set as per the silk screen diagram, NOT as per the ON/OFF logo next to the dip switches. If the diagram were wrong, I'd be getting weird roll-offs when measuring my subs output. As you can see from my FR plots, I'm not.

Russell,

I have mine set as the manual states for mono bridged but I am getting a drop off at 30hz which would suggest the 30hz filter is applied and when I play the 10 and 20hz test tones I can't hear them. Is the diagram correct in the manual or is it backwards.

Can you change the switches while the amp is on and the sub is running.

cheers

You've read the manual? I thought you were a bloke?

I went with the diagram on the amp, although I have only used the one channel to date. I haven't had the chance to get both subs running at once yet.

To be honest, it should be easy enough to verify with a 20Hz test tone and an SPL metre. Ignore the 30/50Hz option and just switch the ON/OFF selector and go with whichever setting is loudest.

Providing switches 3 and 8 are pushed to the right no filters are applied.

Nimby,

Thats the weird thing on the 2500 the switches for on are all on the right but on the 4000 the input 1 + 2 are reversed, one goes to the left and one goes to the right. This is what is confusing.

cheers

Right, checked it out using REW tonight and I can confirm that if you set 3 & 8 to 'On' and all the others to 'Off' you end up with a full bandwidth stereo amp.

That is correct but according to the diagram from behringer's site you would be running full range speakers in stereo mode and the low frequencies would be cut to either 30 or 50hz.

What I want to know is on input 1 it says that the low cut filter needs to be set to the left to be on and input 2 the low cut filter needs to set to the right to be on. (Opposite way around to each other). Is this correct or is it wrong because on the 2500 the mode switches on the reverse of the amp had the words on on all the right switches and off for the left, but the 4000 amp doesn't have on or off on the back which leads you to think you have to go by the manual. But this is not so for the 2500 which is confusing.

Ah! I see what you mean.

Why don't you just connect one channel at a time and measure what's coming out of the sub depending on which switch you've set? Then you can ignore the website, instructions, diagrams, labeling and forum say-so.

I'll certainly be checking the other channel this way when I've finally dragged the second subs speaker cable around the room and under the carpet. I ain't leaving it to chance when I can see for myself.

I have just had an email back from behringer with regards to the switches and guess what. What they say doesn't match up with what it says in the manual. Their settings for bridged are:

Quote:

Hello Graham,

I confirmed this with the other Tech Staff.

Bridge mode

3 & 10 to the left. 1, 2, 4, 5, 6, 7, 8, 9 to the right

The manual says:

1,6,7,10 are to the right and 2,3,4,5,8,9 are to the left

See what I mean. I get a better more powerful sound when I set them the following:

1,2,3,4,5,6,7,9,10 to the right and 8 to the left

This way all is the same as the manual except for 8 which on input 2 the low cut filter is set to on. Figure that one out. What is right and what is wrong.

cheers

This might not be the best thread (hope you got it sorted Graham) but I have a question re connecting up the EP4000.

On the input side it seems the amp takes balanced Speakon connectors or TRS jacks. If I have a standard RCA lead, as you would from an audio processor/preamp, how do I connect this to the Behringer? I plan to split the line level output from the AP into two RCAs and thence to run the EP4000 in 'stereo' hence I think I need two RCA->mono jack adaptors, eg:

DCS Pro 2 x Pro Mono Jack To Phono | DV247

Is this right?

Thanks in advance chaps, don't have any experience of balanced inputs....

NB

You can use two solid male phono;jack adaptors. No need to pay extra for fancy adaptor cables.

The inputs sockets aren't Speakons they are XLRs.

The output sockets are members of the Speakon/Neutrik family. I've never used them so I've never needed to identify them properly. I just use bare wires on the speaker terminals. Behringer refer to them as Speakon compatible.

Hi everyone, would appreciate a little clarification on this if that's ok. I am planning on running my 2 subs with one input from receiver, splitting the output to both channels in the ep4000 and running a sub from each channel. Now the problem I have is the switches are a little confusing. On the red dip switch unit there is a white 'ON' printed on the right, but on the printed diagram on the right hand side of the amp (looking at it from the back) having the low cut filter off means 3 and 8 need to be pushed to the right. This goes against the dip switch label. As far as I can tell, if I have 1, 3, 4, 5, 8 and 10 pushed to the right and the rest to the left, then I'm running both channels from one input, with the clip limiter for both channels turned on and the low cut filters turned off. Is this correct?
