DAM-124

12 channel wired digital automatic mixer (DAM-124)

Digital intelligent conference processor is a combination of digital audio and digital control technology. With high-performance DSP as the core and special control software, it can make detailed settings and adjustments for each channel. It has its own 12X4 matrix, full intelligent conference management, and simple digital intelligent conference system.

Functional Features

• Automatic sound valve 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;
• Separate working channel – It has 12 independent input working channels, and each channel can adjust the input gain independently.
• Chassis standard – Standard 1U all metal case, aluminum panel; Clear and bright LED lights on the front panel display the input and output audio dynamic information at all times; Encoder with scale indication.
• 48V phantom power supply – 48V phantom power supply is attached to the input channel; 4-channel linear input; Independent mute control and phantom power control; Priority selection and pressure limit adjustment can be set for each channel.
• NOM Microphone Attenuation – It supports automatic attenuation value adjustment of NOM multi-channel microphones, and the maximum number of open microphones supports 1~8.
• Integrated control – Support the grouping setting of mute and other control parameters; The conference scene mode is saved to provide a very convenient debugging method for similar venues.
