FP 14000
FP 14000 continues the renowned reputation of Lab.gruppen by further augmenting effective power output to effortlessly handle extreme low-frequency loads.The Regulated Switch Mode Power Supply (R.SMPS) has been updated to provide more sustained high power during extended bursts of low frequency content, while at the same time ensuring stable rail voltages even with wide fluctuations of external mains voltage. The forceful, high-current (83 A peak) output stage relies on Lab.gruppen’s patented Class TD topology, a breakthrough in amplifier technology that approaches the efficiency of Class D while retaining the sonic purity of proven Class B designs. A highly refined and efficient circuit layout further optimizes the interaction of R.SMPS and Class TD to produce the unprecedented power density of the FP 14000.
To keep its cool under extreme demands, the FP 14000 relies on Lab.gruppen’s proprietary Intercooler. This innovation uses thousands of copper fins to multiply the exposed heatsink surface’s rapid heat dissipation. Also, all output devices are mounted transverse to the airflow for uniform cooling. As a result, the FP 14000 delivers Lab.gruppen’s’ trademark “all the power, all the time” with no degradation of sonic performance.
To maximize headroom in any application, the FP 14000 offers adjustable input gain along with Lab.gruppen’s exclusive Voltage Peak Limiter (VPL). Adjustable on a per-channel basis, VPL optimizes the output for any load, from a single massive subwoofer to a series of HF compression drivers.
The comprehensive warning and protection features on the FP 14000, safeguard output circuits and connected loads while also extending amplifier life and minimizing the chance of service interruptions. Whether it’s a matter of faulty wiring, improper use, or extreme ambient temperatures, the FP 14000 gives clear indication of any problems. Automatic protection measures engage only at critical thresholds. Operating conditions are re-checked every six seconds and, if a fault is detected, normal operation is resumed when measurements return to nominal.
The FP 14000 is shipped with a NomadLink network interface as standard. In conjunction with DeviceControl software, NomadLink allows comprehensive monitoring of amplifier status (including fault or warning indications) and also enables remote control of power on/off, channel mute, and channel solo functions. NomadLink is compatible with popular third-party control platforms; a separate NLB 60E NomadLink Bridge & Network Controller is required.

Notes *1: Regarding n.r. (not recommended) notes: The amplifier will be fully operational in bridge-mode into 2 ohm and high impedance (Hi-Z) loads, but due to physical constraints in the construction, the max. output power will not be significantly higher than running individual channels and therefore this mode of operation is not recommended. *2: Automatic -6 dB gain compensation when bridging channels. *3: Separate 230 V or 115 V versions available. Not selectable on the amplifier. *4: PAL can reduce the maximum output power to keep the power supply operating safely, and/or to prevent excessive current draw tripping the mains breaker. Refer to the FP+ Operation Manual section 7.5.8 Power Average Limiter (PAL) for more information.
