The amplifiers we stock are mainly designed to be teamed up with a set of PA speakers for live sound at gigs and parties, where they're used to power - and send signals to - passive speakers. As such, most PA amps are two-channel stereo amplifiers, fitted with inputs that can be connected to the main output of a mixing console or any other audio source.
Stereo Amplifiers for PA Speakers and Subwoofers
Since PA amps are equipped with a limited number of ports, one of the most important things to look at are the type and the number of inputs and outputs. In most cases, you're set up with two channels and two (line-level) inputs per channel, e.g. XLR and RCA. The outputs of a PA amp - which will be either locking speaker outputs in the form of Neutrik SpeakON ports; wire terminals; jack ports or a Euroblock terminal - send out power as well as the audio signal for passive speakers or passive subwoofers. A lockable speaker connection is the most secure option since it prevents short circuiting and damage as a result of accidental unplugs. Bear in mind that it's not possible to connect both a passive subwoofer and a passive full-range speaker to the same amplifier. You'll need a separate amp for your subwoofer(s) and your full-range speaker(s) as well as an external crossover system to split the high and low frequencies. Once you have what you need, plug your audio source into the inputs of the crossover before connecting the outputs of the crossover with your amplifiers.
HiFi Amplifiers Featuring WiFi, Bluetooth and DAB+ Support
Most people think of Hi-Fi amps at the mention of the word 'amplifier'. Technically speaking, they're correct since Hi-Fi amplifiers also feature ports that can feed power to passive speakers. That said, Hi-Fi amps are designed for the living room and not the stage, meaning the focus is mainly on the audio quality instead of the power capacity and sound pressure level, which are two specifications that are key when it comes to PA speaker systems. As the heart of your Hi-Fi system, a Hi-Fi amplifier allows you to hook up various audio sources, like your TV, CD-player, radio, Blu-Ray player, record player and other gear via analogue inputs as well as digital connections like HDMI, Toslink, WiFi, Ethernet and Bluetooth. Hi-Fi amps also come fitted with various speaker outputs which, depending on the model, simply cover stereo sound or support home-cinema-style surround-sound via a 5.1 or 7.1 speaker configuration. A Hi-Fi system can only be built using Hi-Fi amps and speakers; PA amplifiers and speakers cannot be used to complete a home cinema setup.
Headphone Amplifiers
Besides PA amps and HiFi stereo amps, you'll find various headphone amplifiers in our range. Headphone amps can be used in the studio or as part of a Hi-Fi set-up to create more headroom for essential sounds and frequencies.
Frequently Asked Questions About Amplifiers
What's the best amplifier?
That depends on your needs. Some amps are made to drive PA speakers on stage while other models are designed for home stereo set-ups only. In addition to ample power to thrust through your speakers, the right amplifier features the inputs, outputs and playback options that you need depending on your sound source.
What's important to watch out for with amplifiers?
Make sure to pick an amplifier that has enough inputs and outputs to support your gear. When it comes to PA amplifiers, pay attention to the power capacity requirements of your speakers and ensure that the amp has the kind of speaker outputs that you need. At Bax Music, we always recommend going with an amplifier that's able to deliver 150% of the RMS power capacity that your speaker can handle at the same impedance.
What's a good home audio amplifier?
At home, it's best to use a regular HiFi amplifier, like a stereo amp or an amplifier that supports surround sound and offers various digital connection options. HiFi amplifiers often support a combination of speakers and a subwoofer, as well as various playback devices like your TV, CD player, radio, Blu-Ray player, record player and more.
What do amplifiers do?
Amplifiers form the core of your sound system. Instead of reproducing sound, all amplifiers are designed to do is boost the signal before sending it your speakers. Amplifiers are used to power and drive passive speakers and passive subs. Without an amplifier, you won't be able to pull any sound out of a pair of passive speakers.
What's the difference between an amplifier and a receiver?
The only difference between an amplifier and a receiver is that the latter has an integrated radio section.
Which audio amplifier do I need?
If you need an amplifier to power a stage rig or a fixed installation in a restaurant or other business, then get a PA amplifier. If you're looking for an amplifier to set up in your living room, go for a HiFi amplifier/receiver.
How many Watts of power do I need?
When looking for an amplifier to match your speakers or vice versa, take a good look at the product specifications to ensure they're compatible. If you're unsure about whether the products you've chosen are compatible in terms of power, impedance (Ohms), or connectors, you can always get in touch with our Helpdesk. Alternatively, check out our bundles or look at a complete speaker set!
What amplifier does your subwoofer need?
Bear in mind that it's impossible to connect both a passive subwoofer and a passive full-range speaker to the same amplifier. To drive both, you'll need separate amplifiers and an external crossover system to separate the high and low frequencies. Once you have what you need, it's a matter of plugging your audio source into the inputs of the crossover before connecting the outputs of the crossover with your amplifiers.
