Description
RDL SF-NP35E - Dante power amplifier for 100V/70V line, 35W mono, powered by PoE++ or 24V DC
The RDL SF-NP35E is a Class D power amplifier from the SYSFLEX series, which receives one audio channel from the Dante network and outputs it to a mono output for 70V or 100V speaker lines. With an input signal of 0dBFS, it delivers 35W RMS, sufficient to power a group of speakers in an office, conference room, store, or corridor. The amplifier is powered via PoE++ from a network switch, so one cable carries both the signal and power. Optionally, it can be powered by an external 24V DC power supply. The current limiting circuit prevents the PoE++ port from shutting down under heavy load, and the Port Protect LED indicates its activation. The output level is adjusted by an internal VCA circuit via a detachable terminal block: using an external 10kΩ potentiometer, 0-10V DC voltage, or RDL wall controllers. No special software is needed for configuration. The metal housing, thermal and short-circuit protection, and UL 2043 plenum certification allow the amplifier to be installed in spaces above suspended ceilings.
