For those with a large home entertainment system, home theater or multiple room music, you need something can give you enough power to make the most use of it. What you may have right now is a stereo receiver powering everything. That can certainly get the job done, but depending on the situation and your particular system, it might actually make more sense to use a dedicated amplifier as opposed to the stereo receiver you have now. Why not provide more power for your system? The best part is, is that if you choose to go with an amplifier that has multiple channels, you will get both plenty of power and increased flexibility in regards to dividing it according to the separate demands of each area.
All you need is your receiver, and one of its preamp inputs. This is where your new amplifier will get all of its audio information.
The amount of channels needed will depend on how many speakers or speaker pairs you want to power, in addition to the kind of room and uses those speakers are for. Such as the environment (Echoing kitchen, outdoors, small room) and how you would like them to sound. As an example, amplifiers like this can definitely come in handy for outdoor uses, which actually need much more power than speakers used indoor in order to get decent volume levels. With some advanced, like a 12 channel amp, you could actually bridge four channels to just a pair of speakers in order to get more power to them. This lets them reach much higher levels of volume, without causing additional strain on the amplifier. Inside, where the sound bounces around, you wouldn’t need more than two channels per pair, which should more than efficient. If you want only “background noise” in a particular room, you can add just one speaker on a single amp channel, and then set it to a mono configuration.
A set up like thing provides a great deal of versatility. It makes is easy to distribute whatever amount of power you want, to many different areas around the house. You could possibly even daisy chain them to account for more rooms. You’ll receive more than enough power for each room, so you can be sure that the sound you will receive will be excellent and won’t strain your amp. You also completely free up the amplifier section on the receiver itself, allowing you to create the perfect surround sound experience for your home theater. You can pick and choose which rooms get stereo sound, and which ones receive mono.
The downside is that this can be a relatively expensive endeavor in comparison to other options. Again, no other option provides that versatility though. Unless you spend even more on a nicer amplifier, you may be stuck listening to the same music across all of the other speakers, with the exception of the Home theater system. This wouldn’t be ideal if you want to wire these into children’s rooms or those of a roommate.
