First let me say I've been reading all the older threads on driving a sub with a Behringer EP2500. Let me first lay out my setup:
- Pioneer Elite SC-05
- Monitor Audio RX-6's (Left, Right, and Center)
- Refurbished ADS Subwoofer (10" driver I believe, sealed, modified to simply have a + and - pole on the back of the sealed cabinet that connects to the driver). Note: This is working fine driven by a Dayton 240W plate amp I just connected externally temporarily to use it.
- Behringer EP2500
In terms of connections: I have the LFE output of the SC-05 using a single RCA cable in to a *mono* 1/4" adapter (http://www.amazon.com/gp/product/B00...ls_o06_s00_i00
) that then connects to Input 1 of the Behringer EP2500.
The dip switches on the Behringer EP2500 are set as follows, which should put it in to bridged mode and disable the cutoff, etc.:
The EP2500 then connects via the mono terminals to the subwoofer driver.
So the problem: with everything connected up, and playing "300" which has some heavy bass in the beginning, I hear nothing
. The EP2500 is powered on, fans running, with the green LED light indicating its running. However, the signal lights (appears red and yellow/orange) show no sign of life. I've tried playing with the gain knobs and it makes no difference. I also tried upping the subwoofer output on the receiver in the speaker signal settings (I didn't see anything specifically related to LFE output level though).
Does anyone have any ideas? I've been reading that the LFE signal being unbalanced might be an issue, and I need something to convert it to balanced. Suggestions to deal with this include the Cleanbox (with a capacitor mod). I also heard the mic2200 might work, which for the money seemed to be a better option, but I read the manual and it seemed unclear, saying you should prefer the use of balanced inputs.
So yeah, I need some help. Mainly how can I:
1.) Verify the Behringer EP2500 is working properly at all
2.) Boost the LFE signal of the Pioneer SC-05 for the Behringer (ideally under $100).
