The FP-NML2 modules are Dante audio network interface products compatible with mic-level or line-level audio equipment inputs. These modules are designed to be mounted in equipment racks, closets,
conference tables and on shelves or backboards in commercial/industrial installations.

APPLICATION: The FP-NML2 is a high quality converter that provides professional line-level outputs from two Dante network audio channels. Each line output provides +4
dBu balanced for a network digital audio level of -18 dBFS. The professional output directly interfaces with other professional and commercial equipment without the need for
additional gain. Crosstalk is below the noise floor between all outputs across the entire audio spectrum. The noise floor is better than 80 dB below operating level with greater
than 18 dB of headroom. Each output is equipped with a recessed mic/line switch that provides 50 dB of attenuation to feed the microphone input of a mixer-amplifier or other
equipment with mic inputs.

The FP-NML2 is powered from an external 24 Vdc power supply, available separately. The FP-NML2P is equipped to operate from a PoE enabled network switch. The FP-NML2P
will reserve power from the switch even while being powered from an external 24 Vdc supply. If PoE power and an external 24 Vdc supply are both feeding an FP-NML2P, the unit
will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

The FP-NML2 includes a dc output jack and extension cable that allows it to be operated from a common power supply with RDL FLAT-PAK amplifiers. One audio output
connects to the FLAT-PAK amplifier input, and the second output may be connected to an additional amplifier.

The FP-NML2’s superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems.

The FP-NML2 is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured product is
engineered and manufactured in the U.S.A for continuous duty in demanding installations. Built to last. Built to outperform.

y 24 Vdc Pass-Through Jack for Power Supply Sharing with RDL Amplifiers (FP-NML2)
y High Resolution 24 Bit Digital to Analog Conversion
y Legendary RDL Analog Filtering Enhances Superb Audio Performance
y Outputs Mute when Digital Audio Inputs are Inactive
y Normal or Hot-Standby Operation from PoE (Model FP-NML2P)
y Equipped for Rack Mounting or Surface Mounting
