Sony DH-520 Receiver Speaker Connection

[Outsider]

Greetings all

Would I be able to connect my current speakers from the HT below to a Sony DH-520 receiver (thinking of buying one)

http://www.sony.co.za/product/dav-tz530

My current HT only has RCA stereo input so I thought of running it to a receiver first and then to the speakers or would that not quite work due to different connections at the back? My current speakers have a plastic (clip-in) connection at the back including the sub - not sure how that would fit here




Essentially I want all my components (PS3, HD PVR decoder, HT etc.) running to the reciever first and then out to the speakers


Thanks for any help

I've re-read your question 5 times, am of slightly above average intelligence.... but I just don't understand what you are asking... ?

lol

Ok, let me attempt to simplify

I have the following HT - http://www.sony.co.za/product/dav-tz530


My other components include

 - Bravia HD TV
 - PS3
 - HD PVR 2 decoder
 - Apple TV

I want all my sound to run from the HT speakers - however that is not possible due to the fact its reciever is very basic and only has a single RCA stereo input - no optical, etc.

So I'm considering buying the receiver pictured above (Sony DH520) and running everything through it. Then I would take the speakers from my HT and connect them to straight the new receiver. Would that work? In addition - their current connections at the back are small plastic clip-ons so I would have to cut them off and attache new ones - would that affect quality?

All my current speakers have a similar plastic connection to the one pictured below



Hope it reads better this time

Ah, now I understand! Should work as you propose - just check the watt rating of your speakers, and if they're rated lower than what your new amp is capable of you will have to be careful not to blow them (if you hear any distortion, you're playing too loud!).
Also check that the impedance (4 ohm or 8 ohm) can be matched with your new amp's capabilities (shouldn't be a problem.)

Yep, you'll have to snip off those red and white plastic connectors - just make sure you know which wires are positive and negative when you connect to your new amp.
Not sure about the sub as the new amp has a line level (not speaker level) output for the sub.

Longer term you might have to consider getting new speakers as well.

Thanks WaterDog, much appreciated

Here are my current speaker specs


Power Output - Front (RMS) 43W
Power Output - Center (RMS) 89W
Power Output - Surround (RMS) 43W
Power Output - Subwoofer (RMS) 89W
Power Consumption (in Operation) 67W
Power Consumption (in Standby) 1W
Power Output - Total (RMS) 350W[/li][/list]



And here are the receiver specs - around 100W per channel x 7

Amp is 8 Ohms only, not sure about the speakers.

•(8Ohms 1kHz) THD : 1%
•(8Ohms 20-20kHz) THD : 0.09%
•8Ohms 1kHz : 100W + 100W
•8Ohms 20-20kHz : 90W + 90W
•Output Power (JEITA 10%)/ Rated Output Power(0.09% 20Hz-20kHz 4Ohm) : 10%
•Output Power (JEITA 10%)/Rated Output Power(0.09% 20Hz-20kHz 8Ohm) : 130W
•Total : 945W (135W/ch x 7 (8?, 1kHz, 0.05% THD))
•(8Ohms 1kHz) THD : 1%
•(8Ohms 20-20kHz) THD : 0.09%
•8Ohms 1kHz : 100W + 100W
•8Ohms 20-20kHz : 90W + 90W
•Output Power (JEITA 10%)/ Rated Output Power(0.09% 20Hz-20kHz 4Ohm) : 10%
•Output Power (JEITA 10%)/Rated Output Power(0.09% 20Hz-20kHz 8Ohm) : 130W
•Total : 945W (135W/ch x 7 (8?, 1kHz, 0.05% THD))


Would that be too strong for the speakers?


Also - Can I cut standard RCA cables and attach them to the speaker cables for the connectors?

[Outsider]

Oh, and current sub is connected straight into the DVD player - no indvidual power, i.e. passive

Would it work with this partucalr amp? Can I not use a Y splitter - 2x RCA to 1x RCA?

If it's connected straight to the DVD player it can't be passive (without it's own amp) - does the sub have a power cord and volume control of it's own?

It would be too strong for the speakers if you turned it up too much. Also, have a look on the back of the speakers for the ohm rating.

RCA cables are different from speaker connectors - they're only used for the low level audio signal from the different components to the RCA inputs on the back of the amp.
You'll see that on the new amp you can connect speakers by just using the bare wire into the clips except for the main speakers where you can also use banana plugs similar to these:

Sub has no power or volume control. Connected with a stereo double cable to the DVD player

Thanks

But would you anticipate decent sound at moderate to high levels?

[WaterHond]

When you say DVD player do you mean your existing system/ player with built in amp?
From what you say it would indeed be passive and therefore  it won't work with the new amp as it only supplies the low level signal via RCA cable to  self-powered subs.

Thanks

It would be able to go as loud as it did previously but if you push it any louder they will blow. The new amp is better quality so the sound will be slightly better (maybe) - ultimately you will need decent speakers to go with the new amp. Your existing setup is called an HTIB - Home Theatre In a Box, i.e., an all in one system. I'm not familiar with yours but generally you can do much better by buying a better amp (as you are planning) as well as new speakers that match  properly with regards to quality of sound and power handling.

I would really recommend getting the right speakers and sub if you buy the new amp.

Yes - DVD = Existing Home Theatre with built in amp

I've been told this can work for the sub?

Nope, that is just an RCA splitter for low level signals and it won't work as your existing sub needs a speaker level signal. To make your existing passive sub work it will need a sub amp of it's own.

Could I not use the DVD player amp just to power the sub?

Take the sub line out from the new amp and plug into the DVD amp?

[WaterHond]

You could, I suppose but you'll have to carefully match the levels on the DVD amp and you'll have an additional amp using power for 6 channels with only one connected - not ideal. Also the DVD amp probably allocates the frequency spectrum to the sub with it's own built in cross-over which will not match what the new amp is doing.

Those HTIB's are pretty much an all in one creation that have been made with matched components which work best together. You'd be better off selling it complete as it is with speakers and getting the right speakers for the new amp.
