RDL SF-NP35E Overview

  • 1Description

The RDL SF-NP35E is a SysFlex series 35W Dante to 70/100V mono audio amplifier designed to convert one Dante input to a constant voltage amplified output for A/V technicians, system installers, and audio engineers in office buildings, retail environments, and educational facilities. Its Class-D output stage delivers 35W of RMS power at 70 or 100V from a Dante stream at up to 24-bit/96 kHz resolution.

A single RJ45 input accepts a Dante network audio channel, and a terminal block output accommodates connection to 70 or 100V speakers. A detachable terminal block is provided for hookup of remote control of the internal VCA. Thermal and short-circuit protection guard against electrical damage and unintended shutdown.

The SF-NP35E supports powering via a PoE++ network switch or a 24 VDC external power supply (available separately). Engineered and manufactured in the USA, it boasts a durable metal enclosure for reliable toughness.


Converts one Dante network audio channel to a 70 or 100V constant voltage amplified output
Provides 35 watts for a network digital audio level of 0 dBFS
Configuration requires no special software
High-efficiency Class-D output stage produces minimal heat for all levels of expected voice or music production
Supports powering via a PoE++ network switch or from a 24 VDC external power supply (available separately)
LED Mute indicator glows yellow when the output is muted
Valid synchronization to the Dante network is indicated by a green LED visible from the front of the unit
Amplifier power is monitored and the current is limited to protect the PoE++ port against shutting down, even during extreme feedback or square wave modulation conditions
Red rear panel Port Protect LED flashes when the SF-NP35E reduces power consumption to prevent shutdown of the PoE++ port voltage
Equipped with an internal VCA for setting the output level
Detachable terminal block provides for the connection of an external 10-kOhm potentiometer or a 0 to 10 VDC control voltage
Amplifier gain remains at maximum when the VCA input terminal is not connected
RDL remote controls are available to provide single-turn, multi-turn (rotary encoder), or button (ramp or fixed-level selection) user level control
Constructed in a durable all-metal enclosure suitable for free-standing, surface-mounted, or rack-mounted operation
Engineered and manufactured in the USA for continuous duty in demanding installations
