The amp will use quiescent power at all times if it is used in a class other than class. As the water analogy implies, the amp is not a pusher of power rather, it serves as a reservoir of power. In a different field, determining the speaker’s volume is a complex matter because the amount of amplifier power as well as the speaker’s efficiency are critical factors. When designing an amplifier, the output stages serve as the answer. Impurities in a speaker are caused by capacitance, reactantance, and resistance of the crossover network at different frequencies. Matching units allow dynamic impedance in the speaker, but they must be set to a level that does not fall below a certain threshold. When a speaker’s impedance is dropped, the amplifier has more power to draw from it. When you put an impedance matching unit in place, your amp will never have an impedance that is less than what is safe to operate at. A amplifier’s power output is not determined by the amplifier’s impedance tolerance. In addition to a matching switch, it is strongly advised that each speaker be matched. Easy load speakers are those that are rated at or above 8 ohms in terms of impedance. The lower the power demanded from the amplifier. The combined impedance should be greater than this. With a little bit of planning and experimentation, you can create a Sonos system that sounds great and is perfect for your home. The good news is that Sonos provides a wide range of amplification options, so you should be able to find a setup that meets your needs. If you have a larger number of speakers or plan on using them at higher volumes, you may need more than one amplifier. For example, the Sonos Connect:Amp can power up to four speakers at once, while the Sonos Amp can power up to eight. The number of amplifiers you can use will depend on the specific model of amplifier you have, as well as the number and types of speakers you intend to connect. Technical Specifications: Line-in connectionsĪuto-detecting analogue (RCA) line-in connection.Īuto-detecting RCA type, adjustable 50-110Hz crossoverĢ-port switch, WiFi enabled to 802.11 b/g/n router.When it comes to Sonos amplifiers, there is no one-size-fits-all answer to the question of how many you can use together. There’s also a subwoofer output, and you’re able to manually adjust the crossover frequency to determine how much bass is sent to the sub. Or you can set up a Sonos Beam at the front of the room, and use the Sonos Amp to drive your own in-wall loudspeakers at the back.Ī set of RCA analogue inputs is ideal for adding your old turntable to the mix. The idea is that you can use the Sonos ecosystem to drive your movie sound, and maybe even pair a couple of Sonos One units as surround speakers. It features the same HDMI ARC module used on the Sonos Beam. The Sonos Amp supports Apple AirPlay 2 to send sound from your iPhone or iPad to any connected speaker, plus you’ll be able to use Apple Music, Spotify and Tidal – Sonos’ ecosystem now supports over 100 streaming services. Better still, you can now power up to four speakers instead of two.Ĭonnectivity is also fully refreshed. The Sonos Amp is twice as powerful as its predecessor, packing 125 watts per channel, which means it’s more than capable of powering even the most demanding speakers.
