Model SF-NP16E

PoE+ Network to 16 W Mono

Audio Amplier - 70 V or 100 V

APPLICATION: The SF-NP16E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage

amplified output. The output provides 16 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the

module.

The SF-NP16E is equipped to operate from a PoE+ enabled network switch. The SF-NP16E may be powered from an external 24 Vdc power

supply, available separately.

If a PoE+ powered device instantaneously demands excessive power from a PoE+ port, that port can shut off its output voltage, causing

a prolonged disruption of the device operation. The SF-NP16E monitors the amplifier power and limits the current to protect the PoE+ port

against shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel PORT PROTECT LED flashes

when the SF-NP16E reduces power consumption to prevent shutdown of the PoE+ port voltage.

The SF-NP16E is equipped with an internal VCA for setting the output level. A detachable terminal block provides for the connection of an

external 10 KΩ potentiometer or a 0 to 10 Vdc control voltage. The 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 pushbutton (ramp or fixed level selection)

user level control. VCA control insures long term noise-free level adjustment.

The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat

for all levels of expected voice or music modulation. An 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.

The SF-NP16E is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted

operation. This full-featured SYSFLEX product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The

versatility of SYSFLEX products adds enormous flexibility in the design and installation of professional A/V systems.

The SysFlex® series is a family of A/V modules providing complex interface solutions at the click of a connector. Certain SysFlex modules provide

connectorized interface between data networks and analog and digital audio devices. Other SysFlex modules include networked and conventional amplifiers

and other application

specific solutions. In RDL’s tradition of versatility, SysFlex modules can be used right where they are needed: Rack-mounted,

Surface-mounted, or unmounted. They are light-weight, compact and easy to install with simple, straightforward switch settings and LED indicators.

Modules quickly snap into the SysFlex rack mount and each is firmly secured with a single screw. The racking system segregates network and power wiring

from the audio and digital audio connectors. For connectorized network audio endpoints and A/V system components that provide unparalleled performance

and advanced features without giving up simplicity and ease of installation, SysFlex is the industry’s best value.
