Pre main amplifier

[Stormydog]

My house was built 20 years ago and I installed stereo ceiling speakers and 2 outdoor speakers (I think 100w) in several rooms. They were hooked up to a simple 2 channel stereo receiver. Played just fine.
Recently I bought Onkyo TX SR393 A/V receiver to create home theater. Hooked up ceiling speakers to Front channel and sound is very low. Contacted Onkyo and finally convinced them that the ceiling speakers are not part of any 3.1 home theater setup, but simple 2 channel stereo. This receiver is home theater, but does have a Line Out Zone B ability which outputs 2 channel stereo to another room. I think this is what I need

However it requires the output to go into a pre main amplifier. I am so confused here as to what I need. I do want to spend less than $100 since it is just to use the ceiling speakers and nothing else. I've looked at something like Nobsound NS-04G PRO Mini Digital Power Amplifier HiFi Stereo 2.0 Channel Class D Home Desktop Audio Amp 100W+100W for $35.
Totally confused with phono pre amp, car pre amps and stereo preamps. Do not need to spend much money on simple use. Any guidance appreciated.

Your receiver lacks pre-outs (pre-amplifier outputs) to use a power amp with the zone 2 line outs (line outs simply output a low level signal without volume control). To use zone 2 you'd need another integrated amp (your avr is a type of integrated amp), so that you could control volume for zone 2. The Nobsound you mention would work.

Low sound on your ceiling speakers (which is a poor place for L/R speakers btw) is more related to the speakers' sensitivity...wattage ratings mean little except a warning as to how much power they can take. Paying attention to speakers' impedance is important along with sensitivity, max wattage is fairly useless.

An integrated amp simply means a pre-amp and amplifier in the same box (a receiver generally added radio tuner in the past, often more about internet capability these days). A phono pre-amp takes the very low signal level of a cartridge (moving magnet type or moving coil type) and boosts it as well as applies the RIAA eq curve needed to play vinyl back properly. A pre-amp would not have amplifiers for passive speakers (basically a switch/volume control only). Car or home would be the same capability in that regard. If your avr had pre-outs then you could use a (power) amplifier to supplement it.

That help?

Are the speakers going through a speaker selector to volume controls and what was the previous receiver/amp (can you describe your equipment a little more?) That model of Onkyo doesn't have a lot of power to drive several speakers at the same time at a moderate volume.

To everettT: I had Levitron speaker 6.5" Cat No. SGC65-00W which is a single stereo speaker in the ceiling in certain rooms. I also have mounted on the outside porch a Left and Right Outdoor speaker Cat No. SG099-00W.
That is info is from a Levitron speaker sheet I have. Each room with the speakers has a volume control mounted into the wall.

I used a Yamaha Natural Sound AV Receiver R-V503. Using (I don't remember what speaker output used - this was 20 years ago) speaker wire to a wall stereo jack. Was able to adjust sound just fine in rooms back then. Went to a home theater setup and I kind of gave up using the ceiling speaks for years and got the ONKYO receiver for home theater using a 3.1 setup as no room for extra speakers in a 5.1 setup. I finally figured out how to wire the wall jacks to the Front speaker outputs. Low volume. After conversing with ONKYO support, I was finally informed that Zone B uses a low power 2 channel stereo output and could use that.

ZONE B LINE OUT jacks: Output audio signals with an analog audio cable
connected to a pre-main amplifier in a separate room (ZONE B).


The ONKYO manual simply says to a pre main amplifier. i am stumped and very confused on how to proceed. Since ONKYO would only recommend their pre amps for like $400 and suggested I do my own research for 3rd party amps. Didn't know where to go for advice and found this site figuring I can get excellent advice. I can't and don't want to spend that kind of money just to get sound to ceiling speakers. Looking for cheaper alternatives to accomplish this. And now I am dumbfounded and looking for advice.

To LovingtheHD: You said "Your receiver lacks pre-outs (pre-amplifier outputs) to use a power amp with the zone 2 line outs (line outs simply output a low level signal without volume control).

That does confuse me. As in my previous reply to everettT, you can see my complete lack of knowledge in all this new technology and confusing to me, information. I know not what to do. Looking for best advice as I don't know where to turn.
