bi wiring

[admin_exported]

Im trying to bi wire my morduants to a cambridge amp.
Cant seem to get it right? The link below takes you to the tech drawing, if you could please tell me what to connect to where id love you lots!! (O:

ive also misplaced the bridges for the back of the speaker ports, does this matter if im not using them when bi wiring?

Thanks for any help you can give me!! nick

How is your speaker cable configured? Do you have four banana plugs at each end of each run?

 

[Bodfish]

Assuming the answer is yes go on the right speaker

E > C

I > B

G > D

K > A

And on the left go

F > C

J > B

H > D

L > A

And you definately don't need the terminals that used to link the binding posts together.

Errr, that would be bi-amping not bi-wiring. For bi-wiring both HF and LF terminals on the speakers go to the same terminal on the amp (HF+ and LF+ to A+ HF- and LF- to A- for each channel, left and right), in other words you'd only be using the A OR B terminals on the amp, not both of them.

 

[Bodfish]

Sorry, but it isn't. You can't bi-amp with an integrated amp that has two channels anyway. That was why I asked whether the OP had four bananas and each end of his speaker cable. If he only has two banana plugs at one end of his speaker cable then yes, he should use this at the amp end as you have descibed.

sorry boddy your confused

biwiring is as the_lhc said

 

[The_Lhc]

So the A and B outputs on this amp are the same channels?

 

[Bodfish]

What am I describing then, cos it sure aint bi-amping!?

the_lhc:So the A and B outputs on this amp are the same channels?
Yes,which is why it is Bi-Wiring...... The clue is in the fact it's a Stereo intergrated amp, if it had four seperate channels,well it would be a multi-channel amp.

the_lhc:So the A and B outputs on this amp are the same channels?

Yes! The idea of A and B outputs is to support the connection of another set of speakers (ie in another room). Normally both outputs are 'on' (sometimes they are switchable) so I maintain you can biwire the speaker in the way I've described - I have used this sort of configuration is the past without any problems.

looks like everbodys right

if you only have one set of speaker outs then its as the_lhc and i say

if you have 2 sets then you can use both sets as you describe

most amps have only one set tho some cambridge have 2

 

[Bodfish]

And to top it all off, we've probably completely confused the hell out of the OP...

Bodfish:the_lhc:So the A and B outputs on this amp are the same channels?

Yes! The idea of A and B outputs is to support the connection of another set of speakers (ie in another room).

Yeah, I know that much! My AV amp has "B" outputs for the front channels, what I meant was are both outputs connected to the same physical amplifier stages?

Normally both outputs are 'on' (sometimes they are switchable) so I maintain you can biwire the speaker in the way I've described - I have used this sort of configuration is the past without any problems.
Yes, if A and B are the same amp stage then logically this is bi-wiring, usually though bi-wiring (in my experience at any rate) means taking two cables from each terminal, which is why I was confused.

Yes,which is why it is Bi-Wiring...... The clue is in the fact it's a Stereo intergrated amp, if it had four seperate channels,well it would be a multi-channel amp.

Hmm, would it? If it only had stereo inputs and the outputs could only be used for stereo, then it would still be a stereo amp wouldn't it(as opposed to a multi-channel AV amp for example)?

Either way it doesn't really matter in this case.

Hoorah! My work here is done...

 

[Bodfish]

''Yeah, I know that much! My AV amp has "B" outputs for the front channels, what I meant was are both outputs connected to the same physical amplifier stages?''

I would certainly imagine so yes. AV is not really my bag, so to speak, but I would be surprised if it wasn't.

I think what Dave is getting at is that there are some amp manufacturers who supply their amps specifically to support a bi-amp configuration (i.e. 4 channels of amplification) in a single chasis case (I think Audionet and Phonosophie).

Thanks for allll of the info... though i must admit i only understood the first 3 responses lolill try the configuration and see how it goes (O:Nick

Hi,

If the "A" set of terminals on your amp are for the right and left speakers you want (and "B" for another room) then do:

Right Speaker:

E - C+D and I - A+B

Left Speaker:

F - C+D and J - A+B

if your speaker cable has 2 connectord on one end and 4 on the other (2 - 4).

if the cable is 2 - 2

Right Speaker

E - C(connector bridge between C+D) and I - B(connector bridge between A+B)

Left Speaker:

F - C(connector bridge between C+D) and J - B(connector bridge between A+B)

if the speaker wire is 4-4, then check in the manual if the "B" set are ouptutting the same signal and are for bi-wiring. If not then you will need 2-4 or 2-2 cable

Hope that helps,

Dan.

for christ's sake, get some bi-wire cable, connect + to red - to black at amp end, and the same at the speaker end, some cable has a smooth end and a ridged end so ridge for red smooth for black, you only need to connect the amp end to one set of terminals and the other end to the speaker terminals in correct phase, I.E rib or + to red and smooth or - to black, dont worry about 4 terminals on the amp end just connect the 4 terminals at the speaker end or do what i do and dont biwire, it makes no difference. Here we go.

Good post Gregory

Why biwire ?..................I don't think it make any difference other than costing you more for speaker cables. It may sound different but not necessarly better

Not really a great post...given that the OP said he didn't have the terminal bridges any more he doesn't have a great deal of choice...unless you want to get into after market jumper leads?

And 'it may sound different but not necessarily better'...??? Isn't that generally how hi fi works? Horses for courses and all that?

 

[Anonymous]

doesnt have to go for after market leads a bit of his speaker cable will do fine

its only wire after all

 

[Bodfish]

Really? I was under the impression there were magic pixies running up and down between the amp and speakers delivering little packets of musical information? That's what makes it so damn expensive right?

 

[Anonymous]

oh dear

that explains everything

there not pixies but elves which is why you dont need to biwire
