PA 4100

Installed sound amplifier

Suitable for almost any installation, this versatile installed sound amplifier features 4 independent outputs of 250 W with their own tone controls and independent volume. It supports low and high impedance loads.

PA 4100 features 4 audio inputs with volume control that can be independently set up as Mic or Line inputs with +48 V phantom power, phase inversion and High-pass filter functions (selectable by dip-switch blocks). The first Mic input has a selectable priority circuit. It also features two Aux inputs, remotely triggerable chime, siren and telephone paging.
