I have a pair of Pentas mk1 I'd like to hook up to my receiver, an Onkyo tx-8011 http://www.onkyousa.com/Products/model.php?m=TX-8011&class=Receiver
Right now I am using a headphone jack adapter, 1/4" to 2 female rca connectors (cheapo cable), and plugging the Pentas into the rca connections using line out on the speakers. This works, but there are two issues. One is there's a loud pop from the speakers when I power on the receiver. Other is that there is fairly loud static in the speakers at all times when powered on, whether or not any sound is coming through.
i don't think the primary problem is with the speakers as I've had them hooked into a beomaster 5500 using line out into the 5500 pre amp jacks and the static and pop were not there.
is there a simple fix here, e.g., connecting these two components differently or using different or better quality cables? The goal is to use the Pentas for my tv, DVD player, CD player etc.
sorry if this is quite basic, I'm a novice. I love the Pentas but would like to avoid buying additional components of possible. Any help greatly appreciated.

Hi,
Unfortunately your receiver is not the most suitable for connecting active B&O speakers. The hum and buzz you are hearing is a common problem when connecting beolabs to a headphone jack.
What you need is a receiver with a volume controlled preamp out. Looking at the onkyo it should not be difficult to find a similar model with the same kind of inputs for not too high a price with this preamp out.
Or, you could use the beomaster, it has similar inputs to the onkyo (tape, phono)

I built it to solve this exact problem. The schematics are easy to find online if you have little electronics know-how. There are also commercially available units like it, but they're usually overpriced, especially when you consider the cost of materials. It basically attenuates the speaker output and turns it into line-out (up to 250watts, I believe).

Would this do the job?

Yup, that would do it. It's one of those "commercially available" units I mentioned in my earlier post. It's a excellent/quick solution if soldering isn't your thing. Opportunity cost, I guess. For me, it was a case of loving DIY, and generally being a cheap-person (cost of parts was appx $10USD)
