The MDL2-12N-19" 1U RACK(I) -500-1024 digital audio recorder (auxiliary power supply ±18..75V) is an industrial solution for reliable multi-channel audio recording in environments requiring high stability and autonomy. The device is housed in a standard 19-inch, 1U-high enclosure, allowing for easy integration into server racks, communication cabinets, and dispatch control systems.

A key feature of this modification is support for an extended supply voltage range of ±18...75V, making the recorder an ideal choice for energy facilities, transportation, telecommunications infrastructure, and other industrial systems with unstable or specialized power supplies. This ensures stable operation of the equipment even with significant voltage fluctuations and increases overall system fault tolerance.

This model supports simultaneous recording of up to 12 audio channels with high-quality digital signal processing. The use of modern digitization and filtering algorithms allows for clear recording of voice messages and process signals without distortion and interference. Isolated inputs (RACK(I) design) provide additional protection against electromagnetic interference and guarantee correct operation in harsh industrial conditions.

A built-in 500 GB drive ensures long-term storage of audio archives. Efficient compression algorithms achieve an optimal balance between recording quality and storage capacity. A loop recording function is implemented with automatic overwriting of obsolete data, eliminating the need for manual monitoring of available space.

The recorder is equipped with an Ethernet network interface for remote access, configuration, and management. The user can search recordings by time, date, channel, or event, and play audio files in real time. Simultaneous operation by multiple users with access rights is supported.

Additionally, a signal level activation (VAD) recording function is implemented, allowing automatic recording of only significant events and reducing the load on the storage system. Audio files can be exported to standard formats for further analysis or transfer to other information systems.

The recorder's hardware platform is built on Based on reliable industrial electronics designed for 24/7 operation, the device is resistant to external influences and power surges and is suitable for use in mission-critical systems.

The MDL2-12N-19"1U RACK(I) -500-1024 (±18..75V) is used in control centers, energy facilities, transportation, security services, and corporate communications networks. The solution ensures accurate recording of conversations and events, increasing the level of control and safety of technological processes.
