Speaker OUTPUTS
The HD900/5 employs JL Audio’s exclusive Regulated, Intelligent Power Supply (R.I.P.S.) design. The operation of the R.I.P.S. system is independent for each channel section. This sophisticated power supply allows the amplifier to produce its optimum power into higher impedances as well as low impedances.
The
entirely automatic and adjusts itself every time the amplifier is turned on. There are no user controls to configure. The system operates through multiple stages of impedance optimization, choosing the stage most appropriate to the actual impedance of the speakers you connect to it.
If you connect a load higher than 4Ω nominal per channel in stereo mode (or 8Ω in bridged mode), power will drop by half with every doubling of impedance above 4Ω stereo / 8Ω mono. If you connect a load lower than 1.5Ω nominal per channel in stereo mode (or 3Ω in bridged mode, the amplifier protection circuitry activates a “safe” mode which reduces amplifier power to protect the circuitry from failure (the LED status indicator on the control panel will light up amber to indicate that this has happened). See page 15 for details.
