No HF & weak LF response in a Yahama DXR-15 powered speaker

I need to find out where I can find top level / schematic drawings / diagrams for a unit on my bench as it is currently disassembled with the symptoms of dodgy HF & LF response.

This unit has a class D switching amplifier which is complex enough to be unfixable by you unless you know what you're doing. It would seem from your diagnostic report (dodgy HF LF response) that you're not in any way a qualified bench tech and all you can do with this item is break it further. My advice - since it's still covered under warranty being that it's rather new, return it for a no cost repair at the store where you bought it.

I have Xavian xn125 speakers. How do I connect them in a bi-wired or bi-amp


Bi-wiring basically works wtih one amp. You need a crossover network and a signal doubler to use two amps (bi-amping). There are many diffent ways to bi-amp (horizontal, vertical,...) This link: - -http://www.soundstage.com/synergize/synergize031998.htm-- explains them all. Bi amping is usually not worth the extra price and complexity when used on smaller speakers.

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 need to remove one power amp module from an older KRK Expose E8. The obvious screws have been removed but the module still feels firmly attached to the cabinet. Is there something that I am missing?


Hello
If you have unscrewed all the seating screws of the circuit board, pull out three knobs at the rear side [HF SHELF/SYSTEM LEVEL ADJUST/HF LEVE ADJUST] and rings screwed to the switches of LF Level adjust, and the screws of XLR socket. Amp with its seating frame wcan be pulled out.

OK.

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 have a peavey SP4XT Cabinet . the cross over network has a bi amp input for HF and LF jacks and these work for both LF HF output . Also on this network is two input quarter inch jacks for full range...


The chokes blocks high frequency, the capacitors block low frequency. You would need a digital multimeter to check for continuity. Make sure none of the resistor is burnt, which may not be obvious.

JRX 125 DJ SPEKER


The JRX series have weak HF drivers, only rated for some 25 watts or so. Are you running in Bi-Amp or straight? Could be bad capacitors in the crossovers. Could also be clipping of your amp, a common cause of failure is using too small an amp and pushing it past it's clean operation limits. Speakers don't like square waves. Was the "Clipping" light flashing on the amp?

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.
