The D-RN2ML is a complete wall-mounted Dante or AES67 audio network interface. It features one XLR mic or line input on the front panel, one stereo Mini-jack line-level input summed to mono on the front panel and two balanced line outputs on a rear-panel detachable wiring block. The module is configured and adjusted using RDL CONSOLE or other network control software. The D-RN2ML fits a standard US single-gang electrical box or can be used with the RDL EP-1 adaptor for mounting in EU/UK square back boxes with 60 mm distance screw hole mounting centers. The D-RN2ML is PoE powered and is available in multiple finishes with optional customized graphics.

RDL has released a line of five single-gang Dante interfaces. The D Series-RN22 and D Series-RN2ML are 2x2 wall-mounted, bidirectional mic/line Dante interfaces, the D Series-RN12 is a 1x2 wall-mounted, bidirectional mic/line Dante interface and the D Series-RN02 is a 0x2 wall-mounted Dante interface. The fifth model – the D Series-BTN21 wall-mounted Bluetooth Dante interface – will be released soon. The models come with a variety of features that are said to help with installation and configuration, including network control of gain, attenuation, phantom power and channel summing, and additional rear-panel inputs and outputs on detachable wiring blocks. The units are available in multiple finishes including black, white and stainless steel. Custom labels can be created and ordered online, and the interfaces fit a standard US single-gang electrical box or can be used with the RDL EP-1 adapter for mounting in EU/UK back boxes. To support the Dante interfaces, the manufacturer has also added two network remote controls: the D-NMC1R and D-NLC1R. These single-gang wall-mounted controllers allow end users to control a wide range of parameters using a simple rotary knob, including volume, presets, muting and Bluetooth settings. Visual feedback is provided through LEDs on the D-NLC1R or an integrated full-colour LCD display on the D-NMC1R.

The RU-NMP44 is a network mixing processor containing six virtual audio mixers controlled by network commands from RDL and other network remote controls. Each mixer operates independently with input signal attenuation from unity to off. The output level from each mixer is independently adjustable from unity to off. Based on the commands sent to the RU-NMP44, each mixer can be used as a mixer, a source selector, a priority paging inserter and/or as a volume control. The outputs from four of the mixers drive corresponding network audio channels. The outputs from two of the mixers drive line-level +4 dBu audio outputs. The RU-NMP44 is configured using RDL CONSOLE or other network control software. If ducking is used, one of the four network audio inputs is assigned as the priority input. That input is connected to all six virtual mixers. An audio detector with installer-defined threshold and recovery delay may be assigned to one, several, or all of the six mixers. For each of those mixers, the priority input is set to a defined level, and the remaining three inputs are each set to attenuate to a fixed level between -10 and -64 dB when a message is detected on the priority input. If hum is anticipated from the paging source, one of four high-pass filter may be enabled. Up to four preset configurations may be stored in the RU-NMP44. Each preset can define any or all mixer level settings. A preset is activated by a network command, an RDL network or wired remote control, a momentary switch closure or a compatible open-collector from other equipment. The RU-NMP44 may be configured to power up to a preset, to the last settings used, or with all levels “off”. The RU-NMP44 may be powered from an external 24 Vdc power supply, available separately. The RU-NMP44 is equipped to operate from a PoE enabled network switch. The RU-NMP44 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 RU-NMP44, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply. The RU-NMP44 is ideal for adding volume control, mixing, switching and ducking to existing network audio systems. The digital signal processing offered in the RU-NMP44 often fulfills all the requirements for an audio system design, such as in classrooms, meeting rooms, restaurants/bars, fitness gyms and retail stores. The RU-NMP44’s superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems. The RU-NMP44 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.

The SF-NP50A is an audio power amplifier that converts one Dante network audio channel and one analog input to a 70 V or 100 V constant voltage amplified output. The output provides 50 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module.

An analog audio source may be connected to either the mono balanced terminal block input or to the unbalanced Mini-Jack which sums the left and right channels to mono. Input gain is set by the installer using a rear-panel single-turn potentiometer with an associated dual-LED VU meter calibrated to 20 dB below maximum power output.

Either the analog input or the network audio input may be used as a paging source. A rear-panel switch is used to set which input has priority. That input utilizes an automatic detection circuit with an adjustable threshold indicated by an LED to attenuate by 25 dB or mute OFF the other input as set by a rear-panel switch. The attenuated input fades up to normal volume when the paging message is finished.

The Dante network audio source drives a balanced line-level output on a detachable terminal block to feed the inputs of other audio equipment or power amplifiers. The output level is +4 dBu balanced for a network level of -20 dBFS.

The SF-NP50A is equipped with an internal VCA for setting the amplifier output level. A detachable terminal block provides for the connection of an external 10 kΩ potentiometer or a 0 to 10 Vdc control voltage. 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. Upon power-up and during overloads or overheating, an LED MUTE indicator glows yellow and 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-NP50A is equipped to operate from an included external 24 Vdc power supply. The SF-NP50A monitors the amplifier power and limits the current to protect the power supply from shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel OVERLOAD PROTECT LED flashes when the SF-NP50A reduces power consumption to prevent shutdown of the power supply.

The SF-NP50A 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.
