adding a sub to my bi amped system

[shoesteve 6]

ive been on line and cant seem to find anything on this topic. maybe im not wording it right. i have the manual for my Sunfire Theater Grand and also my Polk Monitor 70's but neither explain it. i have 2 Carver M500T's bi amped with my Monitor 70's..i have a Polk Sub which im using with my Denon home theater system connected with RCA cables......i cant seem to get the Theater Grand to play in 2 Channel with the sub through RCA cables. i figured i would wire it to the speakers, but how???? if i wasnt bi amping it very clear to me, but using both top and bottom jacks do i need to run 2 sets of speaker wire????? if anyone can shed any light on the topic or refer me to a link id appreciate it..thanks                            ps the sub is small its a Pold PSW-10.....i just wanted to see how it sounded

Sorry but I'm lost....lets take it one step at a time. If your speakers are biamped and working, lets remove that from the question. You have a sub that you want to incorporate into your Sunfire Theatre Grand (Preamp not amp, right?) but you some how have a Denon home theatre amp system connected in there somewhere trying to control your Polk sub? Am I hearing you right?

Your Denon has a Sub pre-out. Simply connect that directly to the sub.

 I have run into this in the past, with trying to get subs to work in 2 channel systems too - usually with Pioneer and Denon receivers.

 

Go into your speaker set up option in the receiver's menu, and change the sub setting from "LFE" to "Yes", or "On".  If your sub setting is on LFE, it will only play LFE info extracted from decoding DD or DTS.  If you change it to Yes, or On, it will engage the cross over, and feed the sub all frequencies below the set point.

 

IMHO, you will NOT like the effect the sub has on your 2 channel listening, but give it a try!

Which model of Theater Grand do you have?

 

In 2 channel mode, you have to change the mains to "small" & choose a crossover frequency between 40 & 160 hz. I know this works with the TG 3 & above, but I'm unsure about the TG 1 & 2....

Are you bi-amping with external or internal crossover?

 

If you wish to use the speaker wire & subwoofer pass-through connections instead of the RCA connection:

 

A: if you are using the internal speaker crossovers, you can run wires from either amp, through the sub to the speakers. I'd use the upper if it were me, but it makes no real difference.

 

B: if you are using an external electronic crossover, use the amp that feeds the woofers as it will have the low frequency signal.

 

Wire the amp to the sub, then from the sub to the appropriate binding posts of the speaker.

to clarify i have the sub hooked up to my denon currently and its working fine...i use the denon for watching movies......simply i wanted to plug the sub into the sunfire theater grand processor....to see how it sounds with my music in 2 channel....when i plug it into the rca sub connects i get nothing....i dont know why....anyways i figured id run it using speaker wire to my speakers but cnt find anything when bi amping.

You have to go into the menu settings on the Sunfire, turn the sub in the menu settings ON. If the sub is on you need to check the sub dB levels on the Sunfire. To help us out here a little, how exactly do you have your Denon connected to the Sunfire through what terminals?

 

[shoesteve 6]

its a denon avr 1906...i have it connected with an rca cable to the center subwoofer jack

[Nahash5150 10,776]

So let me guess...

 

You have you computer connected to the Sunfire (music), and your DVD player (movies) to the Denon right?

 

Why not run an optical TOSLINK from your computer to the Denon? Then you can connect your L & R pre-out to your Sunfire and use us it for everything and allow your Denon to do what it does best and manage all ins and outs. 

[shoesteve 6]

i connect both the denon and the sunfire with a cable that on one end has left and right rca and the other is a microhone jack...i swap them when i want to listen to music i siply pull out the one from the denon..i do not watch dvd's and i dont play cd's i have 2 TB's of music and movies on my storage drives in my pc.....i do not want to run the sunfire all the time. id like to keep it as long as possible so im trying not to "wear it out" sometimes i fall asleep watching movies and i dont want the sunfire getting all that use.. the denon im very happy with but i can get another much easier than the theater grand...

[Nahash5150 10,776]

Then just get an RCA Y splitter and run into the sunfire AND the Denon (aux in). Then when you want to hear the sub, you just select AUX (or whatever RCA input you use on the Denon) and you'll get the SUB pre-out to work with the same signal going to the Sunfire.

[Nahash5150 10,776]

Note: You can MUTE the HT speakers through the Denon.

Electrolytic capacitors last longer if they are in use

thank you hashy i bought the connector and i have the denon on in aux with the sub connected to the aux and turned the speakers off and im getting the sub to function......now im gonna see if i can turn the sunfire/carver system off and play my movies through my computer with out having to un plug anything....brb....back...ok so when i turn the sunfire/ carver off and just use the denon my front/ center/ surround speakers work but not the sub...i can deal with that...all i have to do is change the rca connected to the aux and place it into the sub jack...no biggie....and thanks to rich for the advice on the Electrolytic capacitors....once again problem solved by The Carver Site

Yea, they have a way of doing that

[shoesteve 6]

btw i love the sound with the added sub. i live in an apartment and i cant play my system too loud which sux, but i still piss a few people off from time to time.....i couldnt even think about listening to music and some compact all in one space saver that gets sold in department stores.....omg that seems like it would be torture after knowing the difference. the only reason i know about any of this stuff is cuz my boss had a sunfire system at work and when he was away blew one of the channels and needed to find a suitable replacement.....

[Nahash5150 10,776]

Good to hear.

 

I use my sub from time to time in 2 channel, but usually at -12dB.

That's exactly where I keep mine....
