Especificaciones técnicas :
RMX amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (<0.05 THD) & a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling us to pack up the power you need in a chassis only 2 rack spaces & less than 16" deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling & cooling.
The RMX Series is packed full of professional features that increase performance and flexibility:
The RMX 1850HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications (a RMX 1850HD exclusive!)
Independent defeatable clip limiters reduce distortion without sacrificing peak performance.
Selectable low-frequency filters boost system response, protect speakers and ensure low-end tightness by more precisely matching the amplifier's range to the loudspeakers.
Barrier strip, XLR and 1/4" balanced inputs plus Speakon and binding post outputs provide easy connections.
Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks cool.
