Bogen's Power Vector modular amplifiers offer a wide range of power levels. The amplifiers are designed to work with both high (70/25V) and low (4/8-ohm) impedance speaker systems. V150 Power Amplifier includes eight module bays for plug-in input modules and allows up to four levels of priority between modules. Two module bays are capable of accepting plug-in signal-processing 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.
