Ram Audio RX-3000 Power Amplifier Stereo 2U 2x1450 Watt /4ohm DEMO LIKE AS NEW
The RAM Audio RX Series, is the result of an in depth study, in order to reach the best compromise between economy and dependability. These units, fully manufactured in our Spanish factory, offer extremely high value, while maintaining the features and reliability users can expect from our products.
This series comprises five models cased in an improved rugged steel chassis. All feature twin stereo amplifiers in a completely new design, able to meet any professional requirement with a reasonable investment.
Our main concern when designing these devices, has been to add to our existing offer, economical, powerful and reliable amps with many of the features our clients appreciate in our current models.
RX Series are are a project based on a mono-block approach offering an all-in-one power module that contains the entire amplifier assembly excluding only the toroidal transformer. This topology offers the best quality and reliablity avoiding effectively several inter-connections between the different circuits. The transformer location in one side, allows to shorten to the minimum the cooling tunnel built by the power heat sinks, the fan and the intake and exhaust grills.
The cost-effective RX Series amplifiers are packed with solid and convincing arguments for the professionals researching quality, reliability and value!.
