Rotel Audio Amplifiers
Whether you are trying to push big speakers with a power amp, or get your turntable input matched to the rest of the system with a preamp, Rotel has an audio amplifier for you. When it comes to home audio, amplifiers are in the driver's seat. They take the signals from your various input sources and turn them into something your speakers can use. Without an amp, you wouldn't be able to enjoy any of your music, regardless of your musical tastes.
Every audio amplifier has the same design goals: it exists to take an existing signal and boost it to the point where it can drive speakers. The differences lie in how the company approaches it. Every Rotel amplifier designs around three key features:
- Parts: High quality parts produce higher quality sound. Rotel amps use better parts to ensure a longer life and more overall reliability.
- Design: It's not just what parts you use, it's also how you arrange and install them. By making sure circuit paths maximise performance and minimise interference Rotel gives you the ability to take full advantage of those parts.
- Evaluation: No matter how much time you spend staring at a sine wave on an oscilloscope, it's the human ear that's the key to listening. Rotel uses human evaluation in every stage of design so you get the sound you want, not the noise you don't.
What Should You Look For in an Amplifier?
Just because all amplifiers do the same things it doesn't mean that they are all identical. There are several features you should look at when choosing an amplifier. The more you know about it, the better you are going to be able to match the rest of your audio system to the amplifier and get the most out of your Rotel receiver.
- Power: Every amplifier has a power rating in Watts, both total power and power per channel. Check both the power per channel and the RMS power, which refers to constant output.
- Channels: A dedicated subwoofer amp may only have one channel; surround sound may require as many as seven channels. The number of channels is the number of independent signals the amplifier can process.
- Impedance: Every speaker has an impedance rating, which effectively measures its resistance. Always check the impedance of your speakers against the output of the amplifier.
Choosing a Rotel Amplifier
Whether you want a Rotel power amplifier or a Rotel preamp, there are plenty of options to meet your needs. In the end it all comes down to simple factors like how big a room you have and how many speakers you want to drive. Once you have that figured out the rest is easy.
