Correct way to connect Studio Monitors to preamp outputs
What is the correct way to connect amplified studio monitors to a receiver with preamp outputs? I tried connecting via RCA unbalanced on the back of the monitor to the RCA preamp outputs on the receiver, and it sounds softer than it should. I'm pretty sure the signal is too weak. I'm guessing the speakers were designed to be used primarily via balanced connection, hence the softness to the tonal sound. How do you convert from unbalanced RCA preamp outputs to balanced TRS or XLR inputs?
I'm waiting for a couple cleanbox pros for my own setup. I got fed up with dealing with my Emotiva and the bulk of it and wanted to use self-powered pro speakers for a long time. There is a sound card called Motu which has a full 8 channels of balanced outs for around 5 bills, but that's only USB or Firewire interface, so it wouldn't let me have surround sound on my Xbox One as well as my HTPC. Unfortunately, I'm using the analog outs of my PC's built in sound card, which, while it's leaps and bounds better than the on board sound of old, it's still nowhere near as good as a receiver.
The cleanbox pro route seems to be the only affordable way to get balanced audio from consumer level stuff for multichannel 7.1 audio.
I've got my first pair of LSR 308s waiting patiently for parts express to deliver these baluns (unofficially, that's what people seem to call these types of devices, AFAIK).
Any thoughts on the quality and longevity of an ART brand product? I was thinking maybe the Rolls MB15b Promatch 2-Way Stereo Converter would be better quality, as it is made in USA and Rolls is an older company that has been around a long time. I called Guitar Center and they don't carry it, and can't order it (well they could but it would take over a month), but they thought I would be better off with Rolls than an ART product.
I don't know from personal experience, just passing along the solution I have seen most often on these forums. I haven't read anything negative about the cleanbox, and I've never seen any feedback on the Rolls.
Now that doesn't really mean much. The Rolls could be a far superior product, I just don't know. Sorry I can't be of more help.
Good luck and let us know what you end up with and how it works. I may very well need one of these myself in the near future.
I looked it up, it looks really nice, but I worry that they cut corners in their design and that it's not true differential signalling to create the balanced outputs.
Does anyone on this forum know which XLR-out receivers have true balanced outputs? I read somewhere (here, probably), that the third pin is often simply not connected to anything.
NB: I could be totally off the mark here. I wouldn't want to pay an extra 500 bucks for balanced outputs that are electrically no different than some 2 dollar a piece open ended dummy unbalanced / balanced adapters.
A balanced home theater pre-amp is going to be expensive. The Marantz AV7701 comes to mind, you can get it refurbished at www.accessories4less.com for $1100. Emotiva makes the XMC-1, but it's $2000.
Think the Denon one is not true balanced? Is there a way to check this? I paid $650 for mine with shipping in mint condition used, so a lot less then the AV7701, which was the cheapest one I could find besides the Denon.
