A Benchmark For Touring Amplication
Over the past decade, the tight and transparent sound of
Lab.gruppen touring ampliers has earned the praise of renowned
FOH engineers and leading sound rental companies worldwide.
The FP+ Series model FP 4000 continues this tradition. At the core
of the FP 4000’s performance is the patented Class TD output stage,
a breakthrough amplier topology that approaches the exceptional
efciency of Class D while retaining the sonic purity of proven Class B
technology designs. Further contributing to the remarkable efciency
of the FP 4000 is a Regulated Switch Mode Power Supply (R.SMPS),
which gives the added benet of stabilizing rail voltages to the output
even with wide uctuations of mains voltage. A highly rened and
updated circuit layout optimizes the interaction of R.SMPS and Class
TD to produce the high power density of the FP 4000.
To keep its cool under extreme demands, the FP 4000 relies on
Lab.gruppen’s proprietary Intercooler. This innovation uses thousands of copper ns to multiply the exposed heatsink surface’s rapid
heat dissipation. Also, all output devices are mounted transverse to
the airow for uniform cooling. As a result, the FP 4000 delivers
Lab.gruppen’s’ trademark “all the power, all the time” with no
degradation of sonic performance.
▸ Efcient cooling system – Unique, lightweight Intercooler
per cooling system dissipates more heat to allow extended peak
output.
▸ Adjustable parameters – Selectable Gain, scalable Voltage Peak
Limiter ( VPL
ration for any system or application.
▸ XLR input and link connectors
▸ Heavy-duty binding post or Speakon
▸ Comprehensive protection and warning – Excessive output
current, DC, high temperature, very high frequency ( VHF), short
circuit, open load, mains fuse protection, and soft start.
To maximize headroom in any application, the FP 4000 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 4000 safeguard output circuits and connected loads while also
extending amplier life and minimizing the chance of service interuptions. Whether it’s a matter of faulty wiring, improper use, or extreme
ambient temperatures, the FP 4000 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 4000 is shipped with a NomadLink network interface as
standard. In conjunction with DeviceControl software, NomadLink
allows comprehensive monitoring of amplier 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.
