The EP5004 offers the System Engineer an incredible versatility. From small systems to more complex or larger situations, the EP5004 provides a very cost effective solution without compromising sound quality.
Application oriented
The amplifier is the optimum choice in many situation, from a multi-zone installation to a multi-way monitoring system. In PA systems it is possible to use 2 channel for left and right signals and bridge the other two channels for subwoofer application. The use of dedicated equalization boards guarantee the optimised sonic quality for each speaker without adding the cost of expensive processors. Equalization boards fully dedicated for the RCF Acustica Series Speaker Systems are available. Muting and diagnosis are available from the back panel.
Power and dynamic
Each single amplifier is fully independent and provides up to 550 Watt on a 4 Ohm load. Each pair of amplifiers can independently operate in bridge mode delivering up to 1100 Watt on an 8 Ohm load. Our clip reduction system is dynamically tracking the power supply rail values in order to prevent clipping distortion which assures the delivery of the maximum available power. Attack and release time constants are accurately calculated to prevent any “pumping” effect.
Analog and digital
The signal path is fully analog for tighter bass and clean transparent highs; controls, protections and diagnosis are digital: a proper mix respecting sound quality.
Protection and diagnosis
The system’s protection provide safe operation in the most various and demanding situations. The output relays avoid transient situations at the speaker output; this system guarantees simultaneously the DC current protection and short circuit protection to the amplifier and speakers. The continuous and intensive use of the amplifier is guaranteed with continuous thermal monitoring; an optimised voltage controlled double fan cooling system acts when needed in a proportional way to the heat generated from the output transistors. The thermal controls act independently on the 4 amplifiers and on the power supply transformer. 4 status LED situated on the front panel is possible to monitor in real time each channels working condition.
