Question about Audio Players & Recorders

Open Question

I have a Hartke HA3500 350w bass amp. When I play my bass guitars I get a slight fuzzy distorted sound from all four speakers. So I'm guessing it's not a problem with the speakers. Can you help?

check the setting of your sub and confirm that it is on-check cable of sub and confirm it is connected firmly.-disconnect power cord and reconnect it again.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.

Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

I have a RZC 298W RCA FM/AM tuner/stereo amplifier that I cant find anywhere. It works ok, except its fuzzy. I'm Just curious about schematics and what year it is. it looks like its at least 40 years old....

You could contact a tv repair shop, many shops have schematics that go back many years. You say the sound is fuzzy, is this fuzzy sound when your playing the radio or when you play something throgh the amplifer? If its fuzzy with any source the you might have a bad speaker or speakers. you need to be more discriptive of the fuzzy sound you describe. also. if this unit has a head phone jack, (which I doubt if its 40 years old). you could plug in some head phone and see if the sound is clear there, if so then you know its most likely the speakers.

I have a yamaha rx-v493 reciever and no speakers what should i get that wont blow and wont empty my wallet

Of course you know you're asking a question that could attract more opinion than useful facts.

If you watch the volume and buy efficient name-brand multichannel speakers with REAL bass-handling capacity you'll probably love the sound without endangering your speakers or your ears.

As it is distortion more than raw power that kills speakers you need to keep away from pushing the amps beyond their RATED power (roughly 70 wpc into 8-ohms, @1khz, <.04%THD. I'm a little concerned that the spec in the manual qualifies it as only 1khz instead of the ore honest and meaningful 20-20000 hz it states for the RX-V393.

An under-powered amp will kill speakers faster than an over-poweredf one as it will enter its high distortion region much sooner.

Play-it-by-ear is good advice. If the amps sound strained, back off the volume.

Your room size will play a huge part in the perceived loudness while your household's aesthetic sensibilites will limit the size and visibility of the speakers. Compromise between form and function is almost guaranteed.

Being a long-time audio enthisiast/collector, set in my ways and unwilling to bow to appearance at the cost of the sound, I use full-size (70's and 80's era) Bose speakers (901's and 301's) throughout the room and augment them with a couple of huge subs and large Kenwood 777 center speakers. It ain't cheap or pretty but it rocks movies and music.

I would recommend you do some research into "home theater speaker recommendations" and read some user comments for the various offerings out there. You'll be in a relationship with your A/V system for a long time. Take the time to get it right.

Fuzzy sound from right front speaker output

The main issue is to determine where the distortion is coming from. Does it start in the front and and get amplified or does it appear in the output section only? This will require a fixed signal and an oscilloscope to trace. Check for leaky coupling caps or leaky transistors in at the diff-amp section.

Center Speaker Audio Very Distorted

Love your screen name.

You didn't say what, if anything, preceded the appearance of the problem. There might be a clue.

Can you describe the distortion? Is it excessively bassy? If so, is it happening on all sources?

I'm assuming this is a modern digital receiver that is capable of many soundfield simulations as well as native Dolby Digital, DTS, multi-channel. If so we can use a stereo source and through simulation redirect some of it to the center speaker.

Using one of your receiver's many multi-channel simulation modes, put in a CD or tune an FM station and use it to diagnose the problem during later steps.

If it's only a single source and that source uses individual analog channel RCA cables, swap in another one or temporarily move the Center Channel feed to one of the other channels to see if it's before the receiver (in the source).or inside the receiver.

For multiple sources:

Is your Center speaker defined properly as Large or Small in the receiver's setup menu?The size refers mostly to the bass-handling capacities of all your speakers rather than their physical size. Speakers designated as 'Small' will not be sent much in the way of bass because they can't handle it well. The LFE/subwoofer channel(s) will get all the bass that was intended for them instead.

If you have a Small speaker improperly defined as Large it may be getting bass that it can't handle and that might sound like distortion. Having a Large speaker defiend as Small would result in less bass than expected but otherwise 'clean' sound.

Check the speaker setup in the menu for excessive volume level relative to the others. There is usually a calibration procedure the receiver will use to help you adjust the subjective voume of each speaker using white noise or tones.

Hope this helps.

Can i have more than one speaker coming from the same out output

Yes! The speaker outputs will have an impedance rating from 4Ʊ to 16Ʊ. If you have two speakers that are rated at 8Ʊ they can be wired in parallel for 4Ʊ total or in series for 16Ʊ total. You can even connect more speakers in a series-parallel circuit, say four to result in a sum of 8Ʊ, 16 speakers to result in 8Ʊ and so forth! Study Ohm's Law and you will see how the circuit looks. Series connection for example will have the + lead from one speaker to the - lead of the next then the + of that speaker back to the - of the first speaker. Parallel is just that + to + and - to -. Series parallel is just a combination of the two circuits. If you have a several speakers of the same size within a single cabinet that are all in phase it is like one giant speaker as it is the air moved that makes the sound. Bose speakers phased-arrays use a sophicated application of this principal to get awesome bass with less distortion than one big woofer. Do not go under or over the impedance rating or the amp could suffer. Fusing can help.

How-to connect (wiring) description for Monster Z2 bi-wire speaker cable

If your cable has four ends at one side and two at the other connect positive to the amp and negitive to the amp for first speaker then go to the four cable end put in the first negitive to the top speaker input then the positive side and do the same for the bottom,also remember to take out the links between the sockets,now do the same for the other speaker.
Please note that some speakers dont sound much better when bi-wired but some gain a bit more bass and detail,also the sound stage may open up a little more.
hope this helps.

Sound problem

Make sure all speakers that are hooked up sound ok. If any of them sound lower then the others or sound distorted you may have a speaker with a partially shorted voice coil. If speaker or speakers pop when power is first applied you may have a grounded speaker that should not be grounded. Each speaker wire rides on 6vdc and if any speaker sees a ground you will have 6v across voice coil which would explain any popping noise when first turned on and radio may play for awhile then overheat. be sure speakers are 4 ohm min per ch otherwise amp will run to hot.
