The MDL2-8N-19" 1U RACK(I)-500-1024 digital audio recorder is a professional network solution for multi-channel recording, storage, and analysis of voice data in corporate and industrial communication systems. Designed for use in modern IP infrastructures, the device provides reliable recording of conversations, dispatch messages, and back-office communications 24/7.

This 19" 1U rackmount model allows for installation in server cabinets, telecommunications racks, and data centers. This ensures centralized equipment placement and easy integration into a company's existing IT infrastructure.

This recorder is part of the MDL2-8N network series, offering expanded capabilities for working with IP environments. The device supports not only analog signal sources but also network audio streams (IP/VoIP), making it a versatile tool for upgrading communication systems and implementing modern IP telephony solutions. The model supports eight independent recording channels, enabling simultaneous recording of conversations on multiple lines. Each channel is individually configurable, including recording parameters, audio format, and input sensitivity, allowing for flexible adaptation to specific tasks.

The RACK(I) version is an advanced model and features an improved control panel and additional integration options. The device can be used in projects that require external event processing, interaction with security systems, and centralized recording management.

The storage system utilizes a hybrid architecture:

• built-in 500 GB hard drive

• 1024 MB buffer flash memory

This design ensures highly reliable data storage, protection against data loss, and an extended drive lifespan. The buffer memory receives the data stream first, after which the information is saved to the HDD.

The recorder is equipped with a 10/100 Ethernet interface, enabling integration into a company's local area network. Users can remotely access the recording archive, search, filter, listen to, and administer the system via a web interface or specialized software.

The metal casing and passive cooling system ensure stable, quiet operation with minimal failures. The absence of fans makes this model particularly reliable for 24/7 operation.
