Hello,

I need to know what purchase (cables and possibly something else).

I have the following (on order) and would like suggestions for connecting them

HT Omega eclaro
Polk PSW10 subwoofer
Polk Monitor Series II 40 bookshelf speakers

http://www.htomega.com/filedown/eclaro.pdf
http://www.polkaudio.com/downloads/manual/Monitor_MN.pdf
http://www.polkaudio.com/downloads/manual/PSW10_12_MN.pdf

The eclaro has a 3.5mm miniplug female connector for the sub and the front speakers (1). Unless there is a creative solution you are aware of or there is such a thing as a cable with one 3.5mm to 2 pairs of banana plugs, I probably need another piece of equipment.

Questions

1. Do cables exist that will enable me to connect these items together?
2. If I need to purchase another piece of equipment, what do you recommend?
3. Would a Klipsch ProMedia DD-5.1 Multimedia Digital Decoder Preamplifer help? I think it will solve the cable issue, but not sure if helps/hinders performance. (I happen to have one of these): http://www.klipsch.com/promedia-dd-5-1

Thanks for your help

J

According to Polk, I need an amp or a receiver. Since this is connected to a PC, I want to control everything from the PC and obviously get the most out of the card. What do you recommend and why?

You will a need receiver to power the speakers.

Forget the analogue on the card, everyone's switching to hdmi. does your pc have an hdmi port?

The board is a ASUS P9X79 Pro (http://www.asus.com/Motherboards/Intel_Socket_2011/P9X79_PRO/#specifications)
I do not see an HDMI port listed, I suppose I could add a card to the system.

Do I need both a DAC and a Reciever to connect the speakers to the sound card?

Having a receiver essentially negates the need for a soundcard....

Is your PC homebuilt or did your purchase it from somewhere? If you built it youself using a mobo from Asus or any other brand they typically have HDMI audio or an optical audio out.

If you don't want to buy a receiver, you can just get an amp with an optical input to power the speakers and the sub.

Bleh, didn't see you posted the mobo...

So why don't you get either a DAC, or a reciever with an optical in to power the speakers?

Edit for clarification: Having a soundcard isn't going to help you at all. Optical is a digital signal so it really doesn't matter if it's coming off the sound card you bought or directly from the mobo's on-board optical out.

OK, so if the sound card is a mute point, what do I need to look for in a receiver? I am assuming that there is a limit based on my speakers.

I just bought my first receiver (Denon 2113CI) for a full blown 5.1 system, so I can't really help you too much.

On my PC I'm just using an 8 year old Sony receiver I got for free from a friend and it works fine. My guess is you could just get something cheap on Craig's List and be happy.

One issue I see regarding controlling everything from your computer...you'll probably need to set a max volume on your receiver that corresponds to the max volume on your PC and then only adjust the volume on your PC if that's how you want to control it. I don't mind turning the nob on my receiver so I just have my PC volume maxed out and adjust volume using the receiver.

Is there any reason not to just use an amp?

Can get any of latest model receivers, it will run the polks. i would recommend a receiver since it has basic bass management and a subwoofer out.

if your look for a cheap amp amp, it will run your speakers fine but there is no subwoofer out or optical :

Definately want the subwoofer to work. I am gathering this is not something amps do (at a cost effective price point compared to receivers)?

Yes go for a receiver. It's better in the long run. You can add center channel and surrounds later for a full 5.1 setup.

I would recommend getting a cheap video card with an hdmi port. That way, you you can connect your pc to a receivers hdmi input and take advantage of the newer dolby formats.

Would this be a separate video card specifically for audio? Have you tried this before?

yes it will work fine as a sound card. Hdmi outputs both video and sound.
I have a home theater pc connected to a receiver via hdmi port of the video card.

here's a sample video card with an hdmi output. There are cheaper cards online but I just want to show what it looks like.:

What are you planning on doing with the system? Just music and PC games? I don't see any point on going the HDMI route if you're not seriously considering going 5.1 in the near future.

Passing audio through the optical port to a receiver is more than sufficient, especially if you're sticking with 2.1 for awhile. Not much point in spending a bunch of extra money on a new video card just to support newer surround formats if you don't need them.

I am not sure about 5.1. I may do it if I can figure out how to fit everything into the room. It is possible I may never do it. If I can get the 2.1 working cheaply, I would probably just do that and worry about extra expense later for explansion. Does the HDMI have any real benefits or limitations I should consider?

I asked the same question on the Polk forum board and one person came up with an excellend solution: Adcom GFA-535 amp. The wiring goes from the sound card to the amp to the sub to the speakers. The beauty of the solution is that it is cheap, delivers quality and enables me to control everything from my PC.

Thank you all for your help. I used the information you provided on the different forums to reach the final solution.
