DAM-128D

12 Channels Digital Automatic Mixer with Dante interface (DAM-128D)

DAM-128D Digital intelligent conference processor is the perfect combination of digital audio and digital control technology to high-performance DSP as the core, with dedicated control software, each channel can be set and adjusted in detail, comes with 12X8 matrix, support multiple levels , All intelligent conference management, can easily form a set of powerful, easy to operate digital intelligent conference system. It is applicable to the high demand of court, business center, conference center, hotel and TV station.

Functional Features

• Dante Digital Audio Protocol – 12 channel input, 8 channel output, intelligent digital mixer supporting Dante protocol;
• 48V phantom power supply – 48V phantom power supply is attached to the input channel; 4-channel linear input; 4-channel Dante audio or Dante microphone can switch input channels at will; Independent mute control and phantom power control;
• Multichannel analog output – 4-channel MASTER analog output, and support 4-channel Dante digital signal output at the same time; Each channel output is equipped with 31 segments of graphic equalization, which can be adjusted as required, and the LINE/MIC output level is switched; Limiter and howling suppression settings can effectively limit the output level and protect the next level of audio equipment or speakers;
• DSP Digital Mixing Algorithm – It adopts 40 bit floating point operation, high-speed DSP chip with operating frequency>450MHz, and digital audio automatic mixing algorithm independently developed by Relacart core technology team, which always maintains the style of showing real sound; And supports Dante microphone mixing;
• Automatic valve level regulation – The automatic sound valve adjustment can automatically calculate the appropriate valve level by using the powerful computing system of DSP digital algorithm according to the on-site environmental noise, which is suitable for any harsh conference environment; Finally, keep the time adjustable to ensure that your meeting is more smooth;
• Independent working channel – It has 12 independent input working channels, and each channel can adjust the input gain independently.
