Singtronic PS-888Pro Professional 2000W Power Karaoke Speaker Built in 10" Super Bass + High Frequency Compressor (Pair)
Singtronic PS-888Pro is our first series of Powered speakers, also known as self-powered speakers and active speakers with Max Input: 1000W + 1000W, are loudspeakers that have built-in amplifier. Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs & KJs performing at dance events and Karaoke Venues. They can be connected directly to a Mixing Console, Karaoke Mixer, Karaoke Processor or other low-level audio signal source without the need for an external amplifier. Some active speakers designed for sound reinforcement system use have an onboard mixing console and microphone preamplifier, which enables microphones to be connected directly to the speaker. Singtronic PS-888Pro is an Active speakers have several advantages, the most obvious being their compactness and simplicity. Additionally the amplifier(s) can be designed to closely match the optimal requirements of the speaker it will power; and the speaker designer is not required to include a passive crossover, decreasing production cost and possibly sound quality. Some also claim that the shorter distances between components can decrease external interference and increase fidelity; although this is highly dubious, and the reciprocal argument can also be made. Disadvantages include heavier loudspeaker enclosures; reduced reliability due to active electronic components within; and the need to supply both the audio signal and power to every unit separately, typically requiring two cables to be run to each speaker (as opposed to the single cable required with passive speakers and an external amplifier).
