simonsays1624705859 Posted June 9, 2007 Posted June 9, 2007 Hi, I'm trying to bi-amp and just wanna make sure if I'm doing it right. I connect LF+/- on the speaker to the amp's front speaker; and HF+/- to the surround back. Then change the power amp setting to Front A. Am I doing it right? Will the display on the amp shows that bi-amp is enabled? Thanks.
deepakvali Posted June 10, 2007 Posted June 10, 2007 i do not own the 2307 but the method you applied does not sound like a method to do bi-amp.
simonsays1624705859 Posted June 10, 2007 Author Posted June 10, 2007 oh ... what is wrong? Advice pls? Thanks.

Will the display on the amp shows that bi-amp is enabled? Thanks. theres a totally wrong method to bi-amp. as the name imply, you need two amplifier to "bi-amp". you could either get one amp to drive the HFs, another to drive the LFs; or one amp for each speaker. the latter works only if you have two indentical amp, usually mono amp. running two pairs of cable from single amp to speakers is call "bi-wire". still, one should never use the surround channels from HT/AV receiver. the inferior amp circuit is one thing, the signal sending from surround channel usually never match the front channel. either run two pairs of cable from the single set of speaker terminals on amp or use the B set of front channel speaker output. http://www.fluance.com/wiring.html
SiriuslyCold Posted June 10, 2007 Posted June 10, 2007 epos, do you own the Denon 2307? perhaps you can check your manual some 7.1 receivers let you reassign the surround back amplifiers if you are set up in 5.1 (an the surround back amps are not in use) you can reassign the amps to power another pair of speakers in a second zone, or obviously as a second pair of amplifiers for the front mains. The manual would usually mention which amps should be used to power the low freqs and which amps to power the hi freqs. Of course this is not ideal biamping with two separate amplifiers (and power supplies) but I think the Denon 2307 has such a feature
simonsays1624705859 Posted June 10, 2007 Author Posted June 10, 2007 Denon 2307 allows using the surround back to power the bi-amp. Of course ... getting a separate amp will be ideal, but $$$ does not permit ... for now :) I'm testing both bi-wire and bi-amp on my Wharfedale font. I couldn't find anything on the manual that mention which amp powers which freqs.
petetherock Posted June 10, 2007 Posted June 10, 2007 Hi bro, welcome! IMHO biwire is not worth it for the 2307. If you can borrow some wires, you can try bi-amping with the rear channel speakers. I am not sure if you will hear much benefit. Please avoid spending too much on this project, I reckon you are better off using the $$ buying software or better speakers. The pre-section in this amp is modest, hooking up a power amp helps you drive a less sensitive speaker but the yield in sound quality may not be what you expect. The amp does not differentiate the different frequencies.

Anyway, are you saying that it does not matter where I connect the high and low freq from the speakers to the amp? I've connected low freq from the speaker to the front, and high freq to the surround back. Correct?
petetherock Posted June 11, 2007 Posted June 11, 2007 Yes, the amp does not differentiate. Software - DVDs Audition and see if it makes any difference. P Hi Hi.

SiriuslyCold Posted June 11, 2007 Posted June 11, 2007 I suppose it doesn't especially since all channels are equal power in the specs. The manual should tell you specifically how to do it though
simonsays1624705859 Posted June 11, 2007 Author Posted June 11, 2007 Thanks Guys. I've actaully tried out the bi-amp over the weekend, but didn't get that significant warmer and tighter sound on my Wharfedale 9.1 as compared to my friends' Triangle floorstand; therefore, just wanna make sure I'm doing it right. Guess it's my speaker then.
petetherock Posted June 11, 2007 Posted June 11, 2007 Its not just the speaker, its also the amp :) Somtimes What Lo Fi makes bi-wires / bi amp out to be so much better than it can be ;) Just sit back and enjoy your amp, buy more DVDs bro!
maxngck Posted June 11, 2007 Posted June 11, 2007 hi! does denon 2307 has ch A & B output? my avr 1707 hv both a & b output. so does it mean i can do bi-amp on it? ch a plug to L&R speaker's LF and ch b into L&R HF. then turn both ch a & b on. is this the correct way of bi-amp?
SiriuslyCold Posted June 11, 2007 Posted June 11, 2007 if the 1707 is a 7.1 amp but it does NOT say can bi-amp if set up in 5.1 it would mean that the B speaker is being driven by the same amplifier as the A speaker output , running in parallel. It's not biamping. simonsays is running 5.1 and there are two amplifiers not being used in his 2307 - and those can be reassigned to power the B speakers (for second zone). I don't think the 1707 amps can be reassigned, but you'll have to check your manual for that.
petetherock Posted June 12, 2007 Posted June 12, 2007 Bro, if you like you can bring your amp over to my place and try all the cables / wires and combinations with my speakers (floorstanders) if you like. I have budget items only,none of the 1k per metre cables but you are welcome to experiment. That may save you some $$ spending on something which won't make a whole lot of difference :)
DJQ Posted June 12, 2007 Posted June 12, 2007 oh. all this talk about bi amping... and now i am really mixed up with bi-wire. i guess i better read thru the manual again. before i do anything else. :o
SiriuslyCold Posted June 12, 2007 Posted June 12, 2007 you can bi-wire without bi-amping, but you can't bi-amp without bi-wiring ;D
