Power and Slave Amplifiers for Public Address and Background Music

100V Line and low impedance power amplifiers are most commonly used in commercial environments that require long cable runs to connect multiple speakers. 

Also known as slave and booster amps, power amplifiers usually just provide the power output in a sound system with the inputs controlled by an audio mixer.

Power and slave amplifiers can just have one speaker output or in some cases have multiple output zones, perfect for routing sound too different areas of your establishment.  

Here at Audio Volt we are pleased to bring you a wide range of power and slave amplifiers from professional brands such as W-Audio, Monacor, Apart, Inter-M, and Adastra etc.
