A standard configuration for listening to music is a stereo, two-channel amplifier, which means the amplifier drives a pair of speakers (although these will usually have an output for a subwoofer as well). For surround sound and home theatre setups, a multi-channel amplifier can support as many as seven channels. For small spaces, a mini HiFi amplifier lets you enjoy top quality audio without the compromises of using an all-one system. The names and functions of some stereo components can verge on the arcane, but an amplifier is straightforward. It’s exactly what it sounds like: a component that takes the electrical signal from a connected device, amplifies it, then sends the signal to connected speakers to produce audio. Typically, good speakers employ a separate bass radiator, which allows for better delivery of bass. It also leaves more room for the primary driver to deliver crisp, detailed and well-balanced highs, and the passive radiator drives powerful, clear lows. Enquire from the company about how the speaker of your choice delivers audio.

Most people will choose an integrated amplifier, which means the various stages of amplification are all contained within a single unit. Power—measured in Watts—basically equates to how loud it can get. When driving a pair of identical speakers, a 75W amplifier will be capable of much more volume than a 25W amplifier. That does get a little more complicated when you connect multiple speakers, though, as the power is then further divided (the power rating is often listed as watts-per-channel to reflect this). Just as important as total power output is THD or total harmonic distortion. The lower that number the better, as it means the amplifier is reproducing the audio more accurately.

Speakers are an important consideration. You want enough outputs for the number of speakers you want to drive, and those outputs also need to match the impedance of your speakers (usually either 8-ohms or 6-ohms). You’ll also want to make sure the HiFi amplifier you choose has the inputs for all your sources—including PHONO if you want to connect a turntable and Bluetooth or Wi-Fi if you want to use it to stream audio

FEATURES OF A WIRELESS BLUETOOTH AUDIO AMPLIFIERS

  • Watts of amplifier: It tells you the maximum power output of your amplifier. Like the speakers, you are going to connect to your amplifier increases the power output of your amplifier should also increase. Else you will not be able to get a good sound quality. In-fact total power output of your amplifier must be greater than or equal to the total power required by all the speakers you are going to connect to your amplifier.
  • Bluetooth version: The latest Bluetooth version is presently Bluetooth 5.0. Obsolete Bluetooth versions are not advised to buy as they are difficult to pair and have less operating range also. Along with that, you will not get a faster data transfer speed when compared to the latest version.
  • Impedance: Impedance of your amplifier decides what kind of music quality you will get to listen to. It should always match the impedance of your speakers. So always make sure that impedance of your amplifier is equal to the total impedance of all the speakers you are going to connect to your amplifier.

FACTORS TO CONSIDER WHEN BUYING THIS PRODUCT

With all of these in mind, we list five things that you keep in mind before buying a portable Bluetooth speaker. To get started, the best way to test a speaker is to go to a physical store and listen to how your speaker of choice sounds. Audio often depends on how you personally like it – while some prefer bass-heavy audio, many like a more uniform balance of audio, and all of this only becomes evident only when you listen to it for yourself.

  1. PORTABILITY; for a Bluetooth speaker to be portable it must have a built-in battery. Battery life for a portable speaker tends to be around 6-10 hours, but some last up to 24 hours. One of our favorite portable speakers, the JBL Flip 5, lasts 12 hours per charge.
  2. MULTI-ROOM; Sometimes one speaker just isn’t enough. Luckily, wireless technologies such as Bluetooth and WIFI have put multi-room audio within most budgets. So if you like the idea of pairing multiple speakers together for a bigger sound.
  3. AUX INPUT; Some Bluetooth speakers have a line-in socket, aka an aux-in. This allows you to connect your wireless speaker to any audio source via a cable. This could come in handy for a number of reasons. Firstly, you won’t have to rely on a Bluetooth wireless connection. Older Bluetooth speakers have a limited operational range of around 10 to 30 meters before the connection is lost – there’s no such issue when using good old-fashioned cables.
  4. DURABILITY; Speakers have usually been pristine instruments, but with the new array of activity-oriented speakers, you can now opt for speakers that will not get damaged in a few accidental falls.

CONCLUSION

When considering wireless speakers for a home theater setup, there are several things to consider. The fact that “wireless” doesn’t always really mean wireless is certainly one issue, but, depending on your room layout and the location of your AC power outlets, one of the wireless speaker options discussed above may be viable for your setup. Just keep in mind what speakers require to produce sound when you shop for wireless speaker options.

Amplifiers truly enhance your music listening experience. But you should always go for the one which gives maximum features in minimum possible price. The quality of your amplifier also plays a role when it comes to the durability of your amplifier as you don’t want to spend your money on frequently buying an amplifier. So, you do your research work properly before investing your money in an amplifier.
