Home Audio

[lorelei12]

Inherited a home with built-in speakers, including an in-wall subwoofer. Purchased a Pioneer multi-channel receiver, front, center and back speakers work. Purchased a Dayton 240 watt subwoofer plate amplifier - plugged black and red into the amp from the sub. Running a Y from the amp to the receiver. No sound.
Clear there is no problem with the receiver set-up (mastered that first).
Any thoughts?
I'm a total amateur, but have read every word in the user manuals multiple times.

From receiver, out on a single wire, to the Y plugged into low level input on the amp.
Red and black each out through low level to sub.

Need to verify the sub is working, hook it up to something else.

The outputs on most plate amps are on the amplifier pcb, not the red and black speaker <inputs> on the rear panel. Is this where you have connected your subwoofer? Try posting a detailed picture of both sides of the plate amp or a link..

Thank you! I have to figure out a way to get a picture onto an html, as soon as I figure that out I'll post a pic.
The black and red are not connected to the back - there are black and red wires on the back, (those say they are the output lead for subwoofer driver).

Play the receiver into the speakers. Turn the volume all the way down. Unplug the wire from the front left or right speaker, and connect to the subwoofer, and slowly turn up the volume, just to see if it plays. That will tell you if it is working, or if maybe damaged or become unplugged.

I also feel some tremulation that maybe you are plugging the subwoofer to the speaker INPUT of the plate amp (which is designed to Y- off the speaker output from a receiver).

Try connecting that output you mention to one of your fullrange speakers, again starting with the volume low. You may want the speaker close to your ear depending if your speakers put out much bass or not.

a good time to check "everything"; you can do a lot in a few mins. Do you have an spare iPod with rca jacks? A AA or 9volt battery could check to see if the sub-woofer is okay; connect that to speaker leads only!

A H_U mentioned, out goes to in >>

I don't think you need the Y with the Dayton plate amps; not that a Y would keep it from working.

Not sure if that works to show you a picture.
Thank you very much, someone is coming over tonight who is more familiar than me, and we'll try all of these suggestions.

Hi lorelei12,

You need to connect the speaker to the output of "HIGH LEVEL IN/OUT - TO SPEAKERS", which in your picture is to the left of the "LOW LEVEL - OUTPUT - INPUT". The low level input comes from, e.g.: the subwoofer output of your receiver, and the low level output allows you to send the processed signal to the input of another amplifier, and from there on to a speaker, the low level output cannot drive a speaker directly.

/\ What he said sounds good. It is a bit confusing how it is labled, I can see how a person could get it wrong.

That has to be it then! I'm getting excited.

I understand - the red and the black going to the subwoofer from the amp need to be plugged into the high level.

There are four plugs for this. A red and a black for left and a red and a black for right. I only have one red and one black to plug in.

Thoughts?

P.S. I'm very thankful for your time.
