Audio Systems/Amplifier connection query
QUESTION: Dear Sir,
I have DAV-D2390K Sony DVD home theatre system which I want to upgrade it.
I want to connect one extra yamaha woofer speaker yst-sw012 to the amplifier section.
The audio input to the amplifier is generally by computer only.
ANSWER: If you wish to substitute the yst-sw012 you may do so as well.
But, I understand you wish to connect the yst-sw012 sub in addition. This sub is self-powered and takes a low-level signal whereas the home theatre system subwoofer outlet is speaker power to the subwoofer. Therefore, you must add a "high-low converter" between the sub output and the yst-sw012 input.
The above is for stereo, but you would need only one channel for the sub. You can find these at hi-fi shops and electronic supply houses.
The input to the converter comes from the back of the Sony sub, the output of the box is now a low lever signal for connecting to the input of the Yamaha sub.
Hope this helps. Let me know if you have further questions.

QUESTION: Dear Sir,
Thank you for your expert advice. I suppose this is a guidance rather than a answer which will surely help me to achieve my quest for music. As a layman I could understand that this configuration is possible.
Again I want to know, can an extra amplifier be connected to the said home theatre system amplifier.
Yes, go ahead. There are audio outs on your center unit that can be connected directly to the input of auxiliary amplifiers. You can connect as many as you want.
Sub output is different, however, because it has filter circuits involved, but for full-range audio it is directly connectable. Go ahead and connect directly from output to input for standard available commercial home grade amplifiers and speaker systems.
Look at Crutchfield.com which has many connection systems; search within their web for connections that you want to learn about.
