BOSS Audio Systems R1100M Features

Amplifier class

The R100M is a class AB amp that can produce great quality sound and still perform more efficiently than a class A amp. Its circuitry will help in reducing distortion thus boosting its power output and sound quality. This type of amp has 2 different types of transistors and features from both classes of amps. A class A amp will allow a huge amount of power to pass through its output transistor providing a better high frequency and feedback loop stability, but with no audio signal. You can easily construct this amp with a single device component and very few parts.

The class B amp uses 2 complementary transistors with each providing half of the cycle which helps to improve the efficiency. It has no power passing through its output transistors and no audio signal with a limitation of crossover distortion. When you combine these features, it means your sound system will have a highly efficient amp less prone to distortion. Plus the Mosfet power supply allows electric current to flow but controls the output voltage and current.

High and low-level inputs

Low-level input is measured in voltage while the high-level output is measured in wattage. These 2 inputs will help in carrying the signal from your receiver to your amp and speakers. The RCA or low-level inputs use interconnect cables to link your amp with the source unit and most aftermarket radios have RCA outputs that you can use to connect to different amps. However, factory radios don’t have low-level inputs.

High-level or speaker level inputs are used to connect your amp to an aftermarket radio or factory radio that doesn’t have low-level inputs so you can use the signal from the speaker output as an input source for your amp. The low-level inputs will accept the pre-amp output signal and the low-level inputs will receive your speaker output signals providing more flexibility when building an audio system.

Who is it best suited for?

This is an affordable amp for anyone on a tight budget but still wants an amp with better efficiency and great overall performance than other expensive amps. The R1100M amp will also deliver great power for your car audio system and allows you to connect it in different ways to accommodate different subwoofers.

FAQ

Is Boss amp a good brand?

Boss amps are good amps that will add bass to your audio system. They will also help to increase the sound quality and power output to reduce distortion.

Why does a car amp go-to protection mode?

Andrew Gibbons

According to Andrew Gibbons, playing the guitar is fun but it will take a few months before you can come up with a creative expression. Gibbons is a guitar instructor and has been teaching University music programs for over a decade, when it comes to playing the guitar a lot of factors come into play that determines the type of sounds produced. The guitarist must consider the guitar's neck and body shape, weight, and string type, the amp is also a primary determinant of the sounds produced and that is why Gibbons has created extensive excerpts detailing on the delicate topic. Guitarists must also pick a pose, be it the pro, wizard, hipster, or the old master.
