Setting up a basic home system

I recently purchased a new flat screen TV to replace my old CRT type.

For years I have been using a AiWA CX-NA30 bookshelf system (purchased around 1997) to enhance the audio of the old TV using the RCA output of the TV to the RCA input on the stereo system. Not having an ear or a desire for the latest and greatest in audio I was always satisfied with the results.

Basic outputs of this system: Two wired speakers, A RCA port for a Powered Sub-woofer and two RCA ports for satellite "surround" speakers (16 ohm)
up to point I have only used the basic wired speakers.

The new TV does not have any RCA outputs but only 3.5 mm and a digital audio output.

I then began to use a 3.5 mm to RCA patch cord to accomplish the same thing with the same results as before.

This time I wanted a bit better audio experience. But I still was not ready to spring for a home theater 5.1 system.
For better Bass response I found a Harmen Karden HK395 (actually meant to the PC market)

The only input of this system is a 3.5 port.

My initial testing of was highly satisfying. The combination of the two normal system speakers with the Sub-woofer and the attached two small speakers worked well.

Given all this I have a few questions.

Would it be better if I connect the bookshelf system from the TV using a Digital audio out to the RCA analog in ports on the bookshelf system or patch directly to the Sub-woofer system using a Digital audio out to the 3.5 mm input port?

A secondly, what about the two other RCA output speaker ports I have available for the "surround speakers" I use quotations because to my knowledge the bookshelf system has no channel separation signal processing. I am guessing that the term "surround" was being use rather loosely in those early days of lower end stereo systems.

The most important thing am tying to figure about these "surround" speakers is that the back plate speaker ohm specification calls for 16 ohm. I can not find those anywhere. Can I use some resisters to raise the speakers I can find (4 and 8 ohm) to the specified 16 ohms. Will these other speakers be overkill being I already have a total of 5?

And lastly, in what way, if at all, does this older bookshelf system process Digital Dolby signals
when I watch movies?

I wanted to include a link to the manual for my system, but the SPAM prevention system prevents that. I have not yet figured out the quick 5 post method.

Links for the manual come up near the top of search results under CX-NA350 AIWA


Thanks

Re: Setting up a basic home system

My personal opinion is that if your looking for any sort of decent surround sound and subwoofer management you would be far better off replacing that Aiwa system with an inexpensive receiver. You would probably be able to still use the current speakers that your using now.
Do you have a budget in mind?

Home theater:
Onkyo 805, Yamaha YDP2006EQ, Samson Servo 600 amp
3 EV Sentry 500 monitors across the front, 4 Mission 762i's Surrounds, SVS PB13U sub, Panasonic BDT220, Harmony 1100, Nintendo WiiU
Panasonic PT-AE8000 on a 120" 2,35:1 fixed screen

Living room system:
Sherwood/Newcastle R972, Mission 765's, SVS SBS02's, A/D/S MS3u sub, Yamaha YDG2030EQ
Yamaha KX-393 Tape deck, CDC 805 CD changer, Panasonic BD60, Sony turntable PS-T20
Panasonic TC-P50ST60, HD-PVR & WDTV Live, Harmony 900

Re: Setting up a basic home system

I did look at a GPX system at Fry's the other day. Normally $60 being sold for $30 as a open box item.

I know...I know, that's really cheap and likely a near garbage system. But as I said, my audio tastes are really basic. In the end I decided not to purchase it.

I did not consider the idea reusing the speakers with just a receiver. So what does a reasonable decent receiver cost? I would prefer to spend less than $100

How would I combine the speakers I have. The two that came with the Aiwa and the Sub-Woofer with the two small satellite speakers?

$100 or less would be a waste of money, it just would not be worth it. The lowest I would go is this Yamaha from Accessories4less http://www.accessories4less.com/make...eceiver/1.html for $150
If the subwoofer is self powered meaning it has its own amp it will work in a pinch but dont use the speakers that are with it.

First, forget surround sound. It looks like you don’t have the budget for it. You’re right, your Aiwa is not compatible with any speakers on the market. No one makes 16-ohm speakers, so you’re looking at an entire equipment overhaul. In addition to the receiver Tony mentioned, you’d also need rear- and center-channel speakers. Oh, and a subwoofer.

It sounds like you’re basically happy with your Aiwa system, but would like additional bass. Since the it has an output for an active (i.e. self- powered) subwoofer, I’d suggest just getting a cheap subwoofer. Over the years Yamaha has made numerous little subs for computer speakers and various applications. Check e-bay and there’s no shortage of used ones going for under $100, and any of they will blow away that Harmon-Kardon thing you bought. Just get one with the largest woofer than you can afford and I’m sure you’ll be happy.
