Don't understand how to connect my speakers


the 4 inputs are for biamping, (using separate amplifiers for low and high frequencies). just leave the pins in place and connect the amplifier to one red(+) and one black(-) connector on the speaker. It has an internal crossover to protect the tweeter.

I won't bore you with the long, tedious reasons for the question, but I need help in connecting the amplifier cables to my Wharfedale 8.3 speakers. There are 4 connection points on the speakers: two...


Leave them in, do some reading on Bi-Wiring (BUY Wiring), chuckle to yourself and enjoy the sound. Connect one positive to a positive and one negative to a negative. With the jumpers in place there is no electrical difference.

Problem with Mackie SRM450V2: HFsignal bleeding through LF driver,low HF OUTPUT also. Filter problem i suspect.


There is an entire crossover circuit inside that is BEFORE the amp section. There are 2 separate amps: one for HF and one for LF. Can you describe the noise you are hearing in more detail? Is hte sound effected by the gain controls at all? What happens without any input?

Thanks,
Dan

Do LF and HF +/_ both be connected and if yes do they both go to speaker system A or separate to A and B on the amplifier.


From the factory, those are equipped with "jumpers", one for red-red and one for black-black. This allows for one speaker cable to power one speaker.

The jumpers can be removed, allowing for "bi-wiring", where you run two leads from a single amp channel to both inputs on each speaker. There's also "bi-amping", using a treble amp and a bass amp dedicated to each input.

If the jumpers are missing, you can use a short piece of stripped speaker wire to reconnect the upper and lower binding posts, just be sure to match colors.clmrt5000_0.jpg

I bought some second hand Technics SB HD 501 speakers, & noticed some note on the back that said something about 'risk of fire if not used with proper units etc'. is this true? They have two speaker...


Don't sweat it unless you're going to chain them to an electric arc wielder or something like that. I think your amp would cut out or the sound would get really bad long before a fire started. ;-)

Any typical amplifier that is NOT driven beyond it's capabilities will do just fine. Just make sure the impedance requirements of the amp and the speakers are in the same ballpark. Speakers being too low is possibly a problem but not dangerous, too high is no biggie.

Bi amp


Hi there, I am assuming that you wish to BiWire the speakers. This involves removing the link on the back of the speaker box and running additional speaker leads for the HF drivers, as well as cable for the LF drivers. BiWiring allows you to use different cable that has been designed with high frequency signal path in mind. It may feature things like silver plating, low capacitance, or as many other "features" as can be tagged to the cable to sell it as a specialist HF conductor. The benefits may be subtle, and not be that noticeable. It does isolate the potential voltage drop along the length of the cable associated with LF energy away from the HF side of the speaker system, and take advantage of Skin Effect, where HF energy tends to travel on the surface of the conductor.
Using a single cable for each channel and leaving the links fitted is perfectly fine and will operate no worries. You could go and spend the extra cash and upgrade your cables to HF and LF BiWire.... the sky is the limit on cost here for what may not be a noticeable difference:)
BiAmping in a different story where much more performance increase is achieved by using a separate channel to amplify HF and LF signals. But you need an amp that has a built HF and LF outputs for each channel to do this. They exists but I have not seen any surround amps that have it.
Go with decent quality realistically priced speaker cable first, then add your HF BiWire to the rig if you are looking for that little bit extra from it:) Good luck, and happy listening.

regards
Graeme
