Flexible power across four channels. The V600:4 delivers 600 W of total output power across four channels, with flexible power sharing using powerTANK to dynamically allocate available power where it is needed. Support for 4-ohm, 8-ohm, 70 V, and 100 V loudspeaker systems gives installers the flexibility to use the same amplifier across a wide range of applications. Built-in ecoRAIL technology reduces energy consumption while continuing to deliver audio at levels suitable for background music, while Auto Power Down can reduce consumption even further during extended periods without signal. dualCOOL provides quiet convection cooling during normal operation and adds intelligent fan cooling only when needed, while a PFC power supply and comprehensive protection package support dependable operation under demanding conditions. The V600:4 integrates easily into larger V-Series systems. RJ45 Line-In accepts audio directly from the VZX-8 8-Zone Audio Processor for simple system wiring, while V600:2 and V600:4 amplifiers can be mixed and matched to create the right balance of power, channel count, and cost for each project. Its full-width, 1 RU design supports rack, tabletop, under-surface, or wall installation.
