Manual / Dimensions

STK new CONTROL series amplifiers are next generation professional tools for speaker sound presets. Built in digital controller with LCD screen for setting lots of EQ bands, bi-amp crossover filters, compression limiters, 0 to 100 meters inputs delay with 3m driver delay, precision digital gain. 180 degree phase shift, input signal clip detectors with 28steps 2 channels level meters. All the kind parameters can be setting via USB and own PC software with up to 20 user presets, also the local settings are by rotary encoder switch on the front panel.
Have a high efficiency output stage design with a STK VS digital switch mode power supply that reduced weight while increasing power efficiency.
Control series DSP features are powerful and precision 32-bit floating-point arithmetic, and high quality 24 bit AD/DA converters. All CONTROL series amplifiers are protected damage from shorted outputs,over heating and DC faults for speakers. The output power levels good match to the most popular passive speakers with wide range of speaker impedance.
