Subwoofer connection Carver Surround 5.1 speaker set-up with Harman Kardon AVR 147 receiver has single RCA-type subwoofer output. Subwoofer has dual-right/left RCA input and output connections OR speaker terminals. HK suggested using a Y connector for RCA connection Any issues with this set-up? Thanks

Hello Ranasinghe, you must connect a JBL satellite for each Main L and R output (2 speakers in total)
Connect one JBL for each Surround L and R output (2 speakers in total)
The middle speaker, to the output of the Central channel and the subwoofer, if active or powered, to the RCA subwoofer output on the amplifier
This way you would have all the speakers connected in the Harman Kardon 130

Hola Ranasinghe, debes conectar un JBL sat?lite por cada salida Main L y R ( 2 parlantes en total)
Conectar un JBL por cada salida Surround L y R ( 2 parlantes en total)
El parlante medio, a la salida del canal Central y el subwoofer, si es activo o potenciado, a la salida RCA de subwoofer en el amplificador
De esta manera tendr?as conectados todos los parlantes en el Harman Kardon 130

It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

make sure you have full surround enabled

You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"

That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.

If your connected via the sub pre out on your reciever check your setting to make sure that it is turned on also if this is done you may try using speaker cables to by wire the subwoofer

You have it upon one of several truly odd "standards" in the AV industry but the answer is simple if not quite logical. You will use an RCA type cable from the Sub out or LFE on the receiver to just one of the two inputs on the subwoofer. I usually use the one on the right but it really doesn't matter. The other connectors would be for a system with out a sub out where the speaker wire would be run first to the subwoofer and then out to the speakers. This will not be used at all in your case.

Enjy!

Have you tried connecting an AV cable from yoursuboofer to your TV?
If so, what type of connection cable does your Woofer have?

Is your subwoofer apart of a surround sound system or is a separate unit?

Most subwoofers with RCA type connections are powered subs. They are commonly sold in most hi-fi stores.
Unless your subwoofer has a separate mains lead it will be the wrong type I think.

There is a setting under your speaker setup to turn the subwoofer on. If speakers are set to small it auto matically sets the subwoofer to ON. If the speakers are set to large it turns the subwoofer off but you can manually adjust.
