Stewart Audio – MC850-MXZ-D

The MC850-MXZ-D has 6 channels @ 70/100V, and 2 channels @ 4/8 Ohm. The 1RU amplifier delivers 50W per channel with channel-to-channel power sharing. The MC850-MXZ-D has 6 channels @ 70/100V, and 2 channels @ 4/8 Ohm. The 1RU amplifier delivers 50W per channel with channel-to-channel power sharing. It has Ethernet and RS-232 control. The MC850-MXZ-D amplifier supports Dante™ audio and has AES67 support. The MC850 family embodies the future of smart amplification with networked audio inputs, Ethernet configuration, control and reporting and flexible power allocation between channels. Whether it’s low impedance, 70V/100V or a mix of the two, there is a model for you with 8 channels and a total of 400W. Setup and configuration can be done anywhere with network access allowing the installer to locate in the zone for real time feedback. The software is simple, intuitive and targeted in scope to make set up easy and allow for granular control. There are 8 independent Dante™ inputs. The MC850 family is AES67 compatible. We built the MC850 family with the network in mind and you’ll find it shows.       
  • 8 independent Dante™ inputs
  • Primary and Secondary Dante™ ports (redundant or switched)
  • Ethernet port for control and reporting
  • RS-232 control
  • Power sharing up to 100W per channel
  • Compact 1RU enclosure
  • Made in USA

AtlasIED – DNA2404DL

The DNA2404DL amplifier is an integral part of theAtlasIED GLOBALCOM® Communications System, allowing a few audio zones to be added where necessary when a full 16-zone T9160 amplifier frame is not required. The DNA2404DL amplifier is an integral part of theAtlasIED GLOBALCOM® Communications System, allowing a few audio zones to be added where necessary when a full 16-zone T9160 amplifier frame is not required. The amplifier features Audinate's Dante™ digital audio input and four channels of 600 watt amplification. The DNA2404DL is controlled with network commands for selecting input routing and configuring EQ, delay and output levels. Amplifiers may be controlled by a stand-alone GLOBALCOM® configuration utility or through the GLOBALCOM System Management Center.The internal amplifier cards are Class D (switching mode) dual channel 600W amplifiers into the rated loads (70.7 Volts into 8Ω). Class D operation, combined with an integral switching mode power supply, offers many advantages, and the uniqueAtlasIED design makes full use of these benefits. They include higher efficiency, increased reliability, improved performance, and lower operating cost. Switching mode operation combined with high voltage power MOSFET devices make it possible to eliminate the heavy, costly, bulky transformers.AtlasIED’s design is stable under all load conditions (phase angles of 0 to 360 degrees). The amplifier card has 34dB of gain from its analog input to the loudspeaker output. Attenuation is handled ahead of the power amplifier by DSP controls through software.

ALF-MA15075D

The ALF-MA15075D is a compact digital mixing amplifier designed for low or high impedance applications. The mode selector switch allows it to deliver either two channels of 75 watts per channel into 4 or 8 Ω, or a single channel of 150 watts at 70 or 100 V. The use of a Class-D amplifier provides power efficiency and energy-saving. In addition to the amplified speaker output, a line level audio output allows the mixed audio signals to be sent to an additional amplifier or other audio system. Feature:
  •  Inputs: 2 x Dante audio, 1 x optical audio, Stereo balanced analog input, 2 x balanced microphone inputs
  • Outputs: 1 x balanced line level outputs, Stereo Low Impedance amp out, 1 x 70V/100V amplifier output
  • Selectable low or high-impedance operation.
  • 2 x 75 watts @ 4 or 8 Ω.
  • 1 x 150 watts @ 70 or 100 V.
  • Class-D amplifier design.
  • Automatic standby after a period of inactivity to minimize power consumption.
  • Rear panel input level controls for setting Microphones input gain.
  •  Low inrush current to prevent audible “thumps” when multiple amps are powered on simultaneously.
  • Balanced analog audio output for pass-through to an additional amplifier or audio system.
  • Basic integrated DSP functions including five-band Graphic equalizer.
  • GUI Webserver with TCP/IP control for remote control or third-party integration.
  • Trigger port for external mute/ unmute trigger.
  • Front panel signal status LEDs for power, panel button lock, audio source, mute, and real-time volume level.
  • 1U Size
