Rcf as6001 schematic

Hi I have 2 RCF8003-AS POWERED SUBS,the other night I experienced a problem with one of the subs status light coming on and momenterely turning off the signal to that side, normally this is meant to come on I think only when the box gets hot, but this is not the case,both sides of the system are being fed the same mono mix but it is only happening on one side, the limiter light blinks normally but never turns red or anything out of the ordinary, can a too high input level cause this to happen, as its never happened in the past

Hello, Jesse. I doubt I can help, but there is at least one SIMPLE thing you can try - with maybe a 10% chance it wil return your unit to normal: Unplug the unit for 30 seconds, then plug it back in to a DIFFERENT outlet. Oh, yes - there are NO fuses or other "reset" devices. I'm sorry I couldn't offer you more help.

SOURCE: Infinity PS-10 quit working

I think the electronics have a 3 years warranty and the drivers have a five years warranty for this product, maybe you can have it replaced. Maybe the auto on/off signal detector is the culprit.

It sounds like your subwoofer acts as a receiver in its own right. Many low-budget home theater systems act this way, and it may in fact have a Dolby Pro Logic II encoder in it. Your best bet is to hook up either the speakers it came with, or purchase speakers from your local audio visual store. Check its power rating per speaker (in watts) in your manual, and purchase speakers that are rated for it.

The "red and white" input you mention are RCA connectors, and should allow you to connect a source to your system. If you have any more specific questions, please post them here.

SOURCE: mitsu hc3000 problem "red-green status light blinking and no input"

fyremd,

I had an older model (1500) and I think I read in the manual that it will shutdown @ 3000 hrs. You have to replace the lamp itself, not just the bulb. The average price (depending on where you shop) is around $200 dollars or more for a replacement lamp.

I hope this helps. Please let me know!

-Thanks

SOURCE: subwoofer goes to sleep

The receiver automatic speaker set-up set the sub volume at -12 and since it was not getting any signals from the receiver it was doing what it is supposed to be doing (going to the standby mode). This was troubleshooted by Onkyo tech support on a Sunday. All the best about Onkyo customer support.

I have a peavey 1220 powered mixer and I'm trying to hook up to two sp15's top's and 2 18; peavey subs for my band and I can't get the bass seperated so it's out of my tops


Hi. The mixer puts out a full range mix, the solution is in your speaker setup.

Many subs have a built in crossover that splits the signal for the tops. Check your sub specs or manual. If your subs have this, run your output signal to them first and then link them to the tops from the special daisychain socket.

If they don't have one, you can install a passive crossover to your subs or buy an external crossover unit.

The last (and not very good) option is to fake a crossover with the desk's stereo EQ. Connect the subs to the left or right channel and the tops to the other and use the EQ to remove the bass from the tops and vice versa, pan everything dead center. Obviously this sacrifices your stereo sound and isn't brilliant.

Can I plug just one subwoofer into my Yamaha EMX88S? What kind of sub do I need to get for it? Do I need to have 2 subs plugged in for it to sound right? Do I daisy chain the subs with the A15 speakers I...


it is not reccomended to daisy chain passive subs with main speakers, because there is no crossover unit involved. you want a sub to have a crossover frequency around 100hz, so that only frequencies lower than this go through the subs, and not in the main speakers.

you could get away with 1 sub plugged into the mono output on the front, subs dont have to be stereo. you would need a self popwered sub, or an additional amplifier+crossover for passive subs. your best bet would to be to get a powered sub and hook it up to the front panel mono out. powered subs usually already have the crossover built--in.

A pulsin sound from the subs


You don't give us much to go on...

Are your subs self-powered? Disconnect the Line In to see if that makes the pulsing stop. if it does there's some kind of signal coming from UPstream or a cable has poor shielding. If it keeps pulsing something's wrong in the sub's power amp(s).

Isolate that much and come back.

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

Subwoofers were said to be bad


overpowered definitely. when you bridge subs your almost doubling the power. if the subs were set for 2000 then the guy he took them too should have known better or at least turned the power down on the amp.

Powered Or Unpowered Subwoofers For Onkyo TX-8511


Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

Status light red


You may have your subs hooked up to it wrong. Either way the amp is definitely blown. Have a stereo shop check it out and examine your wiring.
