Active speakers
Active speakers contain their own amplifier to drive the speaker, which will be matched by impedance and power handling. This makes them a simple solution for distributed audio systems.

Active PA cabinets with inbuilt amplifier in a moulded polypropylene enclosure. Inputs for microphone and line level input have independent volume settings, with connection options of jack, XLR, RCA or minijack. An inbuilt audio player with independent volume control can accept USB or SD media with mp3 tracks or operate as an FM tuner or Bluetooth® receiver. Output is governed by Treble and Bass tone controls and can be output via an XLR line output. The internal amplifier also has an output for a passive speaker to make a convenient 2-speaker PA system. A comprehensive PA option for DJs, stage performers and presentations.

Our speaker and amplifier products cover many environments and applications with a focus on clear and efficient sound coverage. Here we discuss the different types of systems
There have been many developments in audio electronics, resulting in different amplifier circuit designs. Such designs can be divided into classes, of which 4 main types are relevant to audio – A, AB, H and D.
A summary explaining the key differences between RMS, Max and Peak power ratings.
