The output provides 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module.\u003c\/p\u003e\u003cp\u003eThe SF-NP35E is equipped to operate from a PoE++ enabled network switch. The SF-NP35E may be powered from an external 24 Vdc power supply, available separately.\u003c\/p\u003e\u003cp\u003eIf 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-NP35E 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-NP35E reduces power consumption to prevent shutdown of the PoE++ port voltage.\u003c\/p\u003e\u003cp\u003eThe SF-NP35E is equipped with an internal VCA for setting the output level. A detachable terminal block provides for the connection of an external 10 K? 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe SF-NP35E 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.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e35 Watts RMS Constant Voltage Amplifier\u003c\/li\u003e\n\u003cli\u003e70 V or 100 V Output\u003c\/li\u003e\n\u003cli\u003eConverts One Dante Network Audio Signal to a Mono Constant Voltage Output\u003c\/li\u003e\n\u003cli\u003eSelectable Dante Sample Rates: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz\u003c\/li\u003e\n\u003cli\u003e0 dBFS Input for 35 W Output\u003c\/li\u003e\n\u003cli\u003eAutomatically limits supply current to protect against PoE++ port shutdown\u003c\/li\u003e\n\u003cli\u003eVCA Control on Detachable Terminal Block\u003c\/li\u003e\n\u003cli\u003eExternal Control Using 10 K?
