Lab Gruppen FP2200

Exceptional flexibility and superb performance

The fP 2200 is a lightweight and space-saving power amplifier, ideal for use in high quality touring sound systems as well as in demanding permanent installations.

The latest semiconductor technology is utilized in the ferrite Power (fP) amplifiers. This, together with Lab.gruppen’s proprietary Intercooler® copper cooling system, enhances the capacity of the fP 2200 to deliver sustained power into very low impedance loads (2 ohms nominal). Two easily accessible dust filters on the front ensure a clean front-to-rear airflow. A new bi-phase wiring scheme also increases the current capacity of the switch mode power supply, further extending the power bandwidth in the low end.

Besides the traditionally superb Lab.gruppen sonic performance, a full line of features make the fP 2200 functional in all applications from installation to high performance live sound systems: Regulated Switch Mode Power Supply (R.SMPS™).

Switch-mode amplifiers are commonplace in today’s amplifier market. However, Lab.gruppen’s unique Regulated Switch-mode Power Supply (R.SMPS) technology offers a number of essential advantages that make it superior to other, seemingly similar power supply designs. The most important features are the precise regulation and the extreme power efficiency. The regulated power supply easily deals with high variations in the AC mains voltage: it can drop by up to 20% below its nominal level (e.g. to 180 V instead of 230 V) without affecting audio performance. The power supply is also exceptionally efficient, with only a fraction of the energy from the AC mains is turned into heat. A regulated power supply also affords other sonic advantages, including better cone control while retaining the same fast response as a conventional power supply.

Multiple Position Gain Switch (M.PGS)

To meet the demand for a flexible gain structuring in various system configurations, Lab.gruppen’s fP Series offers a multiple position gain switch. The maximum amplifier gain can be set to all industry standards: 20, 23, 26, 29, 32, 35, 38 and 41 dB.

Sophisticated protection circuitry, combining:

• DC protection – Blocks infrasonic signals due to fault conditions
• VHF protection – Protects the loudspeakers from sustained (non-musical) very high frequency signals above the audible range.
• Thermal protection – Protects the amplifier from overheating. The protection warning indicators on the front panel illuminate before the protection process is initiated.
• AC protection – Shuts down the power supply if the line voltage is outside the operating voltage.
• Clip limiter – Prevents severely clipped waveforms from reaching the loudspeakers while maintaining full peak power.
