Hello,

I have a marantz sr4320 and a jbl e80 speakerset. Also i have a balboa subwoofer system from jbl and a center speakers from jbl. There is also a mixing desk (rodec mixbox).
Now i wanna combine those all together and get the best sound out of it.

The speakers are already working ( the sub and speaker not...cause i dont know where to connect them). The speakers are connected to the marantz receiver...however i also see that it is possible to connect speakers to the subwoofer itself...Maybe its better to connect it too that subwoofer?

I hope somebody can tell me how to connect best.

This are some pictures of the gear. Subwoofer, center speaker and receiver marantz. All photos from the back.

Thanks

Connect speakers to the receiver using speaker wire, and connnect the subwoofer to the receiver using coax.

Thats the way I've always done it and works just fine.

Use the amp to power the speakers using standard speaker wire. I wouldn't use the subs built in amp to power the speakers as its unlikely to be as good an amplifier as the Marantz. The speaker terminals on the sub may actually be an input source for cases where you have no low voltage RCA output from the amp. The resolution of the amplifier pic isn't great enough for me to tell for sure, but it doesn't look like there is a dedicated sub output. It could however have a general L/R output that could be plugged in to the sub's unfiltered L/R input.

The thing is everything is occupied. No more place left to connect speakerwire...

There is a "pre out" on the receiver. Maybe that can be used to connect the subwoofer.
Now i have connected the output of my mixer to the marantz "main in".

Thanks

Post a high resolution pic of the receiver and I can probably help better. If you have a pre-out use that for the sub. A pre-out is pre-amplification an is what you want since the sub has its own one built in.

Your receiver/amp is only stereo so therefore doesn't have a subwoofer output either high level or low level.
Your sub doesn't seem to have a high level input so I would guess there's no way you can easily connect them together. You really need a 5.1 or better receiver/amp to make it all work.

Ok. Some more detailed pictures. As you can see i have a "pre out" but do i need to connect the "balboa sub" onto that...if yes, what cable should i use?

As you can see the "main in" is the where the sound of the mixer comes in.

I also connected the "center" with speaker wire on the "system a" speaker (i used the left side). Does it matter what side you use for the "centerspeaker"?
The regular speakers are connected on "system b".

Thanks

The SR4320 is a stereo amplifier so there is no sub or center input for you to use.

See here for some tips on getting the sub connected up.

If you don't have it, get your manual from here. It'll show you how to connect other devices correctly.

Yeah I'd use the pre-out for the sub if it works, looks like you have that connected correctly with the right RCA cables. If the pre-out doesn't work, it looks like your sub will accept the speaker output from your amp. In this scenario you would wire your amp speaker outputs to the speaker input of the sub, then use the output terminals to go to your speakers. It's kinda of like a pass-though.

You should remove your mix desk from main in and use an input e.g. DVD, then select that input source on the receiver.

Doesn't matter if you use A or B outputs for your speakers, but as mentioned above this is not true 5.1 home theater. You are still only getting L/R stereo output to all speakers.

As I said it is a stereo receiver/amp so you can't satisfactorily connect a centre or sub as there is no internal surround decoders. It is not designed for surround sound.
Although you may be able to physically connect other speakers you will only ever get stereo sound. A sub connected to a stereo receiver will never do what it's designed to do i.e. provide properly decoded low bass in a surround sound system.

Ok. I go try this. Where do i attach the center? to the receiver itself...no more place to put this on my sub.

Here's how to set it up:

SR4320 'System A' speaker outputs -> speaker wire -> JBL e80 speakers

SR4320 'Pre out' L & R -> Red/White RCA cable -> JBL Balboa Sub L & R RCA input

Set cossover on JBL Balboa Sub to 100Hz (about half-way)

Rodec Mixbox L & R output -> Red/White RCA cable -> SR4320 'CD' L & R input

Get rid of the centre speaker. Your SR4320 receiver is stereo only. There is NO SURROUND PROCESSING anywhere in your system so a centre speaker is unnecessary. A well set up stereo system will sound great just on its own.

That's it! Sit back and enjoy :)

I tried doesnt seem to work.

I connected my Mixbox to "cd in".
The speakersconnected via speakerswire on system a.
The "vcr out" i connected to the "l&r" off the subwoofer.

What happens : Only the subwoofer works now...

Thanks

What input are you trying to listen to?
What have you connected the 'pre out' L & R to then?
Or have you got other components connected through the mixbox?
