VP-3504 Digital Power Amplifier 4X500W

VP-3504

The VP-3504 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-3504 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.
