CAMCO Vortex series power amplifiers have precise, pure sound performance and powerful power. Its features are advanced sound design and integrity. Vortex power amplifier can run in stereo, bridge mono and parallel mono working mode, has a large power reserve, stability can reach 1 ohm load, weighs only 12.4kg, specially designed for professional mobile performance, with remote control function.

DS1870 is a dual-channel bias controller for AB class LDMOS RF power amplifier applications. It controls the 256 positions of the potentiometer through look-up table (LUT) based on the amplifier temperature, drain voltage or drain current (or other external monitoring signals). DS1870 has internal temperature sensor and multi-channel A/D converters (ADCs) to provide a cost-effective solution, using nonlinear compensation techniques to improve power amplifier efficiency, which traditional bias solutions cannot provide.
