DIGIAMP 450 X4
4 × 450 W digital power amp
Description
The VMR Digiamp 450x4 is a 4-channel professional power amplifier with a switching power supply and a 1U rack format. It delivers 4 x 450 W at 8 Ω, letting you power several speakers or sound zones from a single rack unit, with lightweight, easy-to-install equipment.
It has balanced XLR inputs, SPEAKON outputs, and a volume knob per channel. The amplifier and the switching power supply have independent cooling, and the fan is continuously variable speed. It includes protection against short circuit, overload, overtemperature, and over/undervoltage, plus automatic amplitude limiting and delayed start-up, which protects speakers from power-on thumps.
It is a practical option for live sound, fixed installations, halls, churches, bars, and PA systems where you need several power channels in little space.
- Protections: Short circuit, overload, overtemperature, over/undervoltage, amplitude limiting, and power-on delay
