SOURCE: Installed new speaker wire (bi-wired).

Since you have confirmed on the amplifier's left channel , it will be necessary to open the set to investigate. Now make sure as you did earlier that the source is not difficient in the left channel. I fyou suspect then use another source and try. Once you have confirmed with the amp, you will need to check on variation of the left with the right, This can also be done with a signal test but if the difference is minimal then a good test of amplification of each section, from the preamp,toneamp or power amp driver or the power output needs attention. get help if you are not familiar so as not to mess up to damage the amp. Other wise if the difference is minimal then adjust in one section or balance to compensate. hope you decide and proceed. Good day

SOURCE: The left channel just went dead on my audiolab 8000p

Hi
I had the same problem & found a solution that might solve yours, too.
The protection relays are **** quality. One on mine (left channel) got stuck and refuses to close although it gets a signal. I replaced both relays with 2 OMRON G2R-1 DC 24V 5PIN ones and now everything is back to normal.

Hi, I have own a pair of peavey impulse 1012 speakers. One of them has developed a fault in that the output is terribly owful at low volume compared to the other one but an increase in the output from the...


"terribly owful " is not a descripption we can really understand. You need to describe whether the probllem is with the bass or treble speaker... lows/highs... The only suggestion we can give is to open the unit. You will need a LONG phillips screwdriver and remove all the screws in wells around the edges from the back and then gently separate the shell. Inspect for loose wiring. You don
t mention if you are using this as bi-amped or not which we need to know. This unit has the soundguard protection of the tweeter which consists of an automotive type lamp and a polyfuse. I would open the unit and see if there is a problem with the connections or possiblly a socket problem with the lamp as that would disturb the tweeter level. If you are bi-ampong this, then verify that swapping the speakers the problem is the speaker and NOT the cable or amp... Also verify the switch on the back of the speaker is properly set.

How To Bi-Amp And Bi-Wire Speakers!


What is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but separately connecting that power source to a woofer and a midrange/tweeter on a speaker.

Bi-amping is using two separate power sources (amplifiers) and connecting one amplifier to a woofer and the other amplifier to a midrange/tweeter on a speaker.

How do I bi-wire?
Your speaker must have two separate positive and negative connections (one set for the woofer and one set for the midrange/tweeter). Connect one wire between the positive terminal on the amplifier/receiver the positive terminal on the speaker. Connect the other wire from the negative terminal on the amplifier/receiver to the corresponding negative terminal on the speaker. Remove the jumper straps connecting the two sets of speaker inputs. Repeat this process for the second set of terminals on the speaker, connecting them to the same positive and negative terminals on the receiver/amplifier. Repeat the steps for each speaker you wish to Bi-Wire, connecting them to the appropriate terminals on your receiver/amplifier.

How do I bi-amp?
Bi-amping is similar to bi-wiring, but involves separate amplifiers: one for the woofer and one for the midrange/tweeter. Passive bi-amping involves a direct hookup between each amplifier and the speaker terminals. True bi-amping involves hooking the preamp to an electronic crossover that replaces the passive crossover network in the speaker. The active crossover then connects to multiple power amplifiers.

Can i bi-wire the front left and right speakers


Not with this unit.

But WHY? Bi-wiring is a myth. Whether the channel's double wires join (dead short) at the amp end or the speaker end makes no electrical difference to the speaker or the sound. But it DOES get you to buy more esoteric wire. Cha-ching for them!!!

But to flip an old saying, believing is seeing (or hearing). Go for it if you want. Someone is always willing to take your money.

Do not know how to connect my kappa 60.5cs to my pioneer cd player do they have to go through an external amp?what do i do with the power plugs on the oppisite side why are there 2 per speaker


You need to run RCA cables from the CD player to the CD or AUX input on your amp / receiver unit. If you have a standalone amp, you need some way to control the volume. Basically, if you have a volume control on the front of your amp, you're OK. If not, you should also have a preamplifier that the CD player feeds first.

From the amplifier, then, a single pair of speaker outputs feeds a single pair of inputs on your speakers. The reason for two jack sets on the speakers is for "bi-wiring" or "bi-amping", not necessary for basic stereo reproduction.

So -

CD red/white RCA out -> preamp/receiver red/white CD/AUX input. Amp speaker output (red + / black -) to one red/black input pair on the speakers. An input on the speaker is side by side...

Keep the red to red, black to black when connecting the speakers, or you will wind up with poor sound and weak bass.

Bi-Amping my speakers with HTR-5850


You can at a minimum, bi-wire your speakers by wiring the speakers with the A and B speaker outputs. The A speaker outputs end up running the tweeters and the B will end up powering the woofers.
