Mono/Single channel operation
R.I.P.S. - Regulated, Intelligent Power Supply
"Regulated" means that the power supply adjusts its operation so as to maintain the amplifier's rated power output and low distortion operation over a wide range of vehicle voltages (11V - 14.5V)
This contrasts with conventional, "unregulated" power supplies, which allow rail voltages to sag in direct proportion to drops in the supply voltage
The "Intelligent" portion of the R.I.P.S. System is a circuit that actually monitors output current to optimize the amplifier's output power over a wide range of load impedances (1.5 ohm to 4 ohm per channel)
Bottom Line - Optimum power, at any impedance between 1.5 ohm and 4 ohm per channel, at any vehicle voltage between 11V and 14.5V
Single Cycle Control - high-fidelity, full-range class D is a reality
Tracking the audio signal, comparing it to the real PWM waveform and then correcting it in each and every cycle (over 400,000 times per second)
Heavy duty aluminum alloy heatsink for heat dissipation
In addition to the sonic benefits of Single Cycle Control Class D, the technology also results in outstanding efficiency
