Again, as stated elsewhere, Receivers are the back-bone of any Home Audio System. When one is referring to a Stereo Receiver, it usually implies a 1 or 2 channel / zone Power Amp, as opposed to a Home Theater or a Multi Zone Digital Audio Receiver. As with other Amplifiers, these Hi Fi Stereo Receivers provide most of the connections to the rest of your HiFi system. As with others we have discussed, they often include a Preamp that controls which audio source is selected, processes the incoming sound signals, and distributes the audio to the left and right channels. We here an General & Install Necessities carry models by Audiosource, AMC, & others.
Many Stereo Receivers are fully capable of running a whole house digital audio system without the need for an additional Power Amplifier. Most have outputs for 4 or 8 Ohm operation. As with other Home Audio Receivers we have discussed, some of these units have multiple channel / zone outputs for whole house audio. If they do not have multi channel capability, one will have to worry about low impedance when connecting multiple speaker pairs to one zone. Impedance is a measure of resistance, calculated in Ohms. If too many speakers are connected to one source the ohms or resistance can become low and potentially damage the source. Hence, if your source does not have multi zone/channel capability, one will have to use an impedance matching / protecting device. Connecting impedance matching volume controls in line from the source (in series) will achieve this. One can achieve the same desired effect by connecting the system through a multi zone speaker selector with impedance protection.
