RDL – SF-NP35E

The SF-NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output.  The SF-NP35E 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 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module. The 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. 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-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. The 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 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-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. Features

CTD-4125

Crown ComTech D Series amplifiers are designed for versatility, flexibility, and ease of installation. With both Dante inputs and outputs, built-in DSP, power sharing, Lo-Z/Hi-Z switching, and a simple to use web configuration interface, ComTech D amplifiers are ideal for meeting the changing demands of diverse installed audio applications. The CTD-4125 delivers 125 watts per channel of legendary Crown amplification when all channels are driven equally. Asymmetrical power sharing enables the four channels to share the full 500W in any ratio, offering unparalleled flexibility. Built-in DSP allows outputs to be tuned specifically for every application and provides the ability to create custom speaker tunings. Factory JBL SpeakerTunings for select JBL models, including Control 400 Series ceiling speakers, are included to simplify the optimization of an all-HARMAN solution. The amplifier can be configured through the intuitive web interface with any computer or tablet and without the need to install proprietary software. It uses HARMAN's HControl protocol to communicate natively with BSS OMNI Processors or AMX MUSE Automation Controllers and includes an easy-to-use API for integration with 3rd-party control systems. This compact 1RU, ½ rack width device can be installed in a rack, under a table, or on a wall using the included mounting hardware.

  • Nexo

Nexo – NXAMP4x4mk2

NEXO’s expertise in DSP control for high-performance loudspeakers is unparalleled in the sound reinforcement industry. And Yamaha has an unrivalled heritage in developing highly efficient and reliable power amplification devices. So when the two collaborate to create a new range of powered controllers, the result is sure to be something special.

With a mains voltage range of 100 to 240 Volts it means the amplifiers can be used anywhere in the world and run on all types of power generators. Robust power supplies use PFC (Power Factor Correction) technology to ensure maximum power conversion efficiency and that the current drawn is smoothed and free of spikes to limit the stress on the mains network at all times. A flexible audio input system encompasses four, high end analogue inputs using cascaded converters for low output noise. Four digital inputs are also available through the rear panel expansion card slot offering optional AES/EBU, EtherSound™, Dante™ or AES67 inputs, all with automatic analogue fall-back. A native dual Ethernet card facilitates remote control and daisy-chaining of amplifiers, and seamless integration with Nexo’s NeMo amplifier management software. In addition to the expansion card slot, other rear panel connectivity includes RS232 serial and GPIO ports along with Speakon outputs for each of the four channels. Occupying only 3U of rack space, the NXAMP4X4MK2 weighs in at just 24.9kg.
