Lab Gruppen FP 3400 Power Amplifier

The FP 3400 Power Amplifier from Lab Gruppen incorporates Lab.gruppen Class TD high efficiency amplifier design, which eliminates the heat and cooling problems found in other extreme high power amplifiers. The Class TD amplifiers maintain the same sonic quality as a traditional Class AB amplifiers. Besides the traditionally superb Lab.gruppen sonic performance, fP3400 offers a full line of important features:

Regulated switch mode power supply
The unique Lab.Gruppen switch-mode power supply technology offers a number of essential advantages that make it superior to other and seemingly similar power supply designs. The most important features are the regulated power supply and the extreme power efficiency. The regulated power supply easily deals with a very high variation 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 any problem. Perhaps even greater benefits result from the extreme efficiency of Lab.Gruppen amplifiers: only a fraction of the energy from the AC mains is turned into heat. A regulated power supply also presents some other sonic advantages, such as better cone control and the same fast response as a conventional power supply.

Multiple positions Gain switch
To meet the demands for a flexible gain structure in the system, Lab.Gruppen 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.
