Right way to connect a 2nd “extension” center channel speaker?
Situation: TV outputting digital audio through an optical cable to a Sony STR-DE995 receiver. Have a set of Klipsch speakers wired to the receiver. So far, so good.
Problem: need to “duplicate” the center channel, OR the entire sound output, to play through a separate speaker in the kitchen. I can see the TV from the kitchen, but can’t hear a damn thing over all the appliances. Can’t turn up the main system b/c then it’s too loud for the people sitting nearby.
I have a separate mini-amp, like a no-name $ 50 Amazon amp, with RCA input and 2x speaker connections. It’s meant to drive a 2nd sub, but I need it to drive a 2nd center / mixed-channels speaker.
The STR-DE995 has a 2nd Zone output, but it ONLY works on ANALOG inputs. It will not duplicate an optical input to the 2nd zone. Sucks.
I know that I “know enough to be dangerous”, so BEFORE I start DIYing things and burn out something or other, I’m asking what’s the right way to achieve this.
Should I take the wire from the AVR to the Center speaker, and splice in the longer wire to the 2nd Center speaker? If so, in parallel or series? I don’t get the whole 4 / 8 / 16-ohm thing.
Should I take the wire from the AVR to the Center speaker, and wire it to the small amp and then run the 2nd Center speaker from that?
If it’s the 2nd, another question is - the small amp has 4 terminals (L+ L- R+ R-) - how should I wire the speaker to it? Connect both + terminals to the + on the speaker, both - terminals to the - on the speakers? OR bridge the + and - on the amp, and connect the “outer” + and - to the speaker?
Given that you have an extra amp, you probably can try something like this: https://www.amazon.com/dp/B00SJ49ZJQ?psc=1&ref=ppx_yo2ov_dt_b_product_details I use them successfully to convert my subwoofer to wireless. They work great and are totally reliable. You will need 2 extra outlets to connect the transmitter and the receiver. Good luck. |
In my opinion, this is not a good idea because the center channel doesn’t have all the signal for 5.1 sound. If the Sony STR-DE995 digital MD tape out can provide PCM Bitstream, you can connect it to a "DAC" to feed the amazon amp in the kitchen for 2 channel stereo. If not, you can using a "Optical Audio Splitter" to connect a "Digital Sound Decoder" convert the 5.1 digital signal to analog stereo signal to provide stereo sound to the amazon amp in your kitchen. TV optical output --> optical audio splitter --> Sony STR-DE995 and digital sound decoder --> Amazon amp --> stereo speakers.

@spenav - that's an interesting idea, but my issue wasn't how to get the signal across the distance (I have a hollow moulding I can drop the wire into), my issue was where to get the signal from in the first place. The AVR doesn't have a 2nd zone output if it's being fed by optical. So I was trying to split off the analog output from the speaker side. @soix - it's the same issue. I would need to somehow duplicate the input to provide signal to the wireless speaker in the first place. @imhififan - it doesn't need to have all the sound, I need the dialogue mostly. Just watching TV shows or documentaries, and can't really hear it if I'm in the kitchen and got mixers / blenders running, or even the water faucet. I WISH the Sony AVR had an output, but apparently if you're feeding it a digital signal, it ONLY puts it out to the speakers, not to anything additional / secondary. Weird, I know. You already have the signal decoded, why not split it off to a 2nd zone as an option? Nope, Sony says you can't. I was trying to avoid having to buy more equipment and having even more connections to manage... LOL. |
