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.
