How to Find the Best Power Amplifier Under 2000 (2024)
Though some of the power amplifiers come at an affordable cost, not all of them are the right fit. Apart from comparing the models we have discussed, you should also know the most crucial factors that can guide you into picking an ideal power amplifier. Some of them include the following.
To correctly match a power amplifier with a speaker, you have to choose one that can offer power that is twice your speaker’s program power rating. If, for instance, you have a speaker with an impedance of 8 ohms and a program power rating of about 350 watts, you should get a power amp that can produce at least 700 watts into 8 ohms.
You should also understand that power amplifiers are categorized into different classes before choosing any model. These classes include A, B, AB, and D. Most popular power amplifiers come in AB and A designs. Though such power amplifiers are known for their excellent sound quality, they come with large components that make them heavy. Such power amplifiers are not economical to use since they lead to high power consumption.
If you need a better power amplifier, consider a class D power amp. This class produces more power than the other categories and maintains excellent sound quality. Such a power amplifier can also minimize the weight of your rack since it will not be cumbersome.
Before you start shopping for a cheap power amplifier, determine the number of channels you require. You can do this by assessing the number of speakers you would like to connect with. Most of the power amplifiers feature two channels and give you the chance to connect at least two speaker cabinets in mono or stereo mode. You may also come across a few budget-friendly models that come with additional channels.
Apart from the classes, power amplifiers under 2000 also come in different modes. The channels of such amps are designed to operate in different configurations based on customer needs. You can either choose a stereo or parallel mode power amp. The market also offers bridge mode power amps that can harness the power of more than one channel.
