Overview:

Occupying the middle of the FP+ Series in power ratings for two-channel models, the FP 9000 provides versatility and value across a wide range of applications for full-range cabinets, band-limited line array systems, and stage monitoring. A refined Class TD® output stage is optimized for effortless reproduction of extreme low frequency content, while the Regulated Switch Mode Power Supply (R.SMPS) has been updated to provide more sustained high power during extended bursts of low frequency content.

Network control

• The FP 9000 is shipped with a NomadLink® network interface as standard. In conjunction with DeviceControl software, NomadLink allows monitoring of all key amplifier parameters and remote control of power on/off, channel mutes, and channel solo functions. 
• NB. NomadLink requires the separate NLB 60E NomadLink Bridge & Network Controller

Proven ergonomics

• View all key performance parameters at a glance – in real time – on the comprehensive front panel display. The FP+ provides the most complete and useful front panel indication on the market today. Bright, color-coded LEDs give clear status indication of all control activation, warnings and faults – without scrolling through menus. Conditions such as blown drivers, shorted lines, and over-temperature channels are easily recognizable. You won’t waste time trying to decipher a generic “trouble light.”

Around the back

• The FP+ rear panel provides all the input and output connections you’ll need plus RJ45 in and out for NomadLink® control and monitoring. With the DIP-switch matrix, you can assign a hard or soft attack to the limiter functions, set overall gain to one of seven different levels, bridge any pair of channels, and set the VPL for optimum output characteristics with the connected load. All in a matter of seconds while the amp is in the rack.

Under the hood 

• To achieve the extreme power-to-size ratio in the FP+ Series, Lab.gruppen engineers refined and upgraded two proprietary technologies: the regulated switch-mode power supply (R.SMPS™) and the patented Class TD™ output stage. Both are incorporated in all four FP+ Series amplifiers. Working together, this new generation of proprietary circuits produces more power from a smaller package while at the same time maintaining Lab.gruppen’s peerless reputation for sonic excellence.
• To ensure efficient, uniform cooling, the ultra-efficient Intercooler® uses thousands of tiny cooper cooling fins to increase exposure of the heat sink to the cooling air flow. Twin variable-speed fans respond to temperature sensors, forcing air over the Intercooler fins in a front-to-rear flow. All output devices are mounted transverse to the airflow, so the cooling effect is uniform. There are no “end-of-tunnel” output transistors subject to greater warming and, consequently, possible premature failure.

Features:

• Exceptional power density – The FP 9000 delivers a total of 9000 W (2 x 4500 W @ 2 ohms) in only 2U.

• Adjustable parameters - Selectable Gain, scalable Voltage Peak Limiter (VPL), and bridge-mode operation allow custom configuration for any application
• Comprehensive protection and warning – Excessive output current, DC, high temperature, very high frequency (VHF), short circuit, open load, mains fuse protection, and soft start
• XLR input connectors
• Heavy-duty binding post or Speakon output connectors

NOTES

1: Automatic -6 dB gain compensation when bridging channels.

2: Separate 230 V or 115 V versions available. Not selectable on the amplifier.

3: 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.
