VP-3304 Digital Power Amplifier 4X300W

VP-3304

The VP-3304 is an Digital Power Amplifier used for the SX-2000, VX-2000 and VM-3000 systems. It is a 2U rack-mount unit equipped with 4 channels of class-D digital power amplifiers, which contribute to energy-saving and lightweight design. The VP-3304 also features a front-mounted LED indicator for operating status indication and stand-by mode to be set for reducing stand-by power consumption. It requires a dedicated power supply unit VX-3000DS or VX-3150DS.
