Refined, Optimized, Effortless
Although an output rating of 2000 W per channel places it at the low end of the FP+ Series, the value-priced FP 4000 has ample reserves for a wide variety of applications, including effortless driving of mid- and high-frequency bands in line array systems as well as the top or bottom end of monitor wedges.
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.
The FP 4000 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. (NomadLink requires the separate NLB 60E NomadLink Bridge & Network Controller)
