A Benchmark For Touring Amplification

Over the past decade, the tight and transparent sound of

Lab.gruppen touring amplifiers has earned the praise of renowned

FOH engineers and leading sound rental companies worldwide.

FP 14000, the new flagship model of the FP+ Series, advances this

tradition 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 fluctua-

tions of external mains voltage. The forceful, high-current (90 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 inter-

action 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 thou-

sands 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 interup-

tions. 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 mea-

surements return to nominal.

The FP 14000 is shipped with a NomadLink network interface as

standard. In conjunction with DeviceControl software, or the leading

third party control platforms, NomadLink network allows monitoring

of all key amplifier parameters and remote control of power on/off,

channel mutes, and channel solo functions. (NomadLink requires the

separate NLB 60E NomadLink Bridge & Network Controller).

▸ Unprecedented power density – The FP 14000 delivers a total of

14000 W (2 x 7000 W @ 2 ohms) in only 2U.

▸ Lab.gruppen sound quality – The FP 14000 is optimized for sus-

tained performance into extreme low-frequency loads, yet it also

maintains Lab.gruppen’s reputation for exceptionally smooth and

transparent mid- and high-frequency response.

▸ NomadLink

network ready – Monitoring and control of key

functions accessible via the intuitive DeviceControl software and

the robust, daisy-chained NomadLink network, as well as by the

leading third party control platforms.

▸ Patented Class TD

amplifier topology – Road-proven output

stage delivers Class B audio quality with Class D efficiency.

▸ Regulated Switch Mode Power Supply (R.SMPS

™

) – Output

power remains constant even with significant drops in the mains

voltage.

▸ Efficient cooling system – Unique, lightweight Intercooler

copper cooling system dissipates more heat to allow extended

peak output.

▸ Adjustable parameters – Selectable Gain, scalable Voltage Peak

Limiter (VPL

™

), and bridge-mode operation allow custom configu-

ration for any system or application.

▸ XLR input and link connectors

▸ Heavy-duty binding posts

▸ Comprehensive protection and warning – Excessive output

current, DC, high temperature, very high frequency (VHF), short

circuit, open load, mains fuse protection, and soft start.
