Cloud VTX 4120 480W Four Channel Power Amplifier, The Cloud VTX 4120 is intended for commercial and industrial public address and sound reinforcement applications where unquestionable long-term reliability is the primary consideration.
The Cloud VTX-4120 is designed to deliver it's full rated power into loads down to 4 ohms for long periods of time. The circuit design includes clip limiting and switch-on delay, together with DC, thermal, short-circuit and reactive load protections. All models are built in a very solid steel 2U chassis, and employ variable–speed forced-air cooling.
The Cloud VTX4120 features pairs of channels which may be operated in Bridge Mode; rear panel switches are provided to enable this. Bridge Mode operation allows power outputs of double the normal rating to be delivered to a load of 8 ohms (minimum).
