Bogen's Wall-Mount Power Vector modular amplifiers offer a wide range of power. The amplifier is designed to work with both high- (70/25V) and low- (4/8-ohm) impedance speaker systems.It includes eight module bays for plug-in input modules and allows for up to four levels of priority between modules. Two module bays are capable of accepting signal processing plug-in output modules. Each module is controlled by an independent volume control with an associated signal/clip LED for signal status. An 11-segment LED output meter monitors output signal level.It includes a motorized master volume control that can be controlled using a remote volume control panel (RVCP, sold separately).
