The MDL2-8-19" 1U RACK digital audio recorder is designed for professional multi-channel recording, storage, and analysis of voice data in control room, corporate, and telecommunications systems. The device is used to record telephone conversations, record operator conversations, document office communications, and create a centralized audio archive at enterprises of various sizes.

This model is designed in a 19" 1U rackmount design, making it ideal for installation in server cabinets, telecommunications racks, and data centers. This design allows for the creation of a centralized recording system within an enterprise's infrastructure and efficient use of rack space.

The recorder supports 8 independent recording channels, enabling simultaneous recording of conversations from various sources. The device is compatible with analog telephone lines, microphones, and line-level audio signals. Universal inputs with galvanic isolation allow for secure connection to communication lines without affecting their operation.

The device is powered by a modern digital signal processor (DSP), ensuring high-quality audio recording and processing. It records using various formats (WAV, MP3, FLAC), allowing for an optimal balance between quality and storage capacity.

The storage system uses a hybrid architecture: data is first recorded to a built-in flash buffer and then saved to a hard drive. This approach significantly improves storage reliability and extends the drive's lifespan.

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, listen, and administer the system via a web interface or specialized software. The device operates without installing drivers and can be used as a network-attached audio storage device.

The metal housing and fanless cooling system ensure reliable 24/7 operation, quiet operation, and minimal power consumption.
