I just pulled the unit out of the box, thinking I would hook it right up to my HT equipment..... I was wrong!

I had bought a length of RCA cable to hook up between the sub/out on the Yamaha DSP-A1 to the input of the Behr. Pro.
Then the output on the Behr. Pro would feed into my Velodyne FSR15.

I know this is rather obvious, but...

There are NO RCA cable inputs on the Behr. Pro unit!
I don't know anything about "balanced/unbalanced input/outputs".

How am I going to hook this thing up? I have searched the forum and had no luck.

I have heard about getting "hum"(no jokes please Posted Image ). How do I avoid that?

I know I need to convert from RCA to one of the available inputs. Which is the correct one? Which is the better one?

I think I may have gotten in over my head, but I can figure it out if someone will steer me in the right direction.

Also, I ran a slow sine wave sweep (15hz-80hz @5sec. each frequency.)

I have a huge gap in the 55hz range. It peaks at around 92dbs at one point and down in the 74db range at 55hz. Should I bring all the peaks and flats down to the 55hz level, since I won't be able to bring that one up?

The average was around 80db.

Thanks for any advice/help!

Accept the 55hz dip. Its a cancellation valley that can only be corrected by relocating your sub (which then just might cause a cancellatin dip at some other frequency). Connections; in the BFD maunal, there is a diagram showing how to wire unballanced cables (your RCA cables) to the BFD's 3 wire 1/4" ballanced phone jacks. It's page 27 in my manual ------------------

Go to Radio Shack or Home Depot and get a 1/4" male mono connector to RCA female connector (it should be a 2" long convertor in total). They are about $1-$2. Plug the 1/4" male plug into the unbalanced input on the BFD (and connect the other end to the receiver's subwoofer output).

If you get hum, get a cheater plug for the power plug. It simply adapts your 3-prong plug into a 2-prong power plug. Home Depot has these for $1 each.

I feel pretty stupid. I didn't know it would be THAT simple. Thanks to both of you! Mike
