■ Car audio amplifier for a compact and user friendly
realization of a powerful car audio system
■ Two independent MOSFET power supplies (R4100A2 /
R2180A2) for high power output and best stability into
low impedance loads
■ Versatile integrated electronic crossovers with filter
slopes of 12/dB/octave. Independently selectable
operation modes: Highpass, bandpass and
fullrange. Fully variable crossover frequency ranges
in between 10Hz - 400Hz for highpass, and 30Hz -
400Hz for lowpass, or both cascaded for bandpass
operation
■ Phase shift control, fully variable in between 0-180°
■ Uncompromising heatsink design, introducing a new
clamshell structure with temperature controlled
internal fan
■ CNC machined power input and speaker output
blocks
■ Adjustable input sensitivity, fully variable from 0.2V
to 9V
■ Advanced protection circuitry, sensing overload,
short-circuits at the speaker outputs, DC voltage at
the outputs and overheating of power electronics
