The MDL2-3-8 digital audio recorder (32GB microSD card + 500GB HDD) is a versatile solution for multi-channel audio recording with a combined storage system. The device is designed for use in dispatch, security, and process control systems that require reliable audio event recording and flexible archiving.

This model supports recording up to 8 audio channels, ensuring stable recording of voice messages and service signals. State-of-the-art digital signal processing algorithms enable high-quality recordings with high speech intelligibility and minimal noise, which is especially important for subsequent analysis of conversations.

A key feature of the device is its combined storage system: a 32GB microSD card is used for immediate recording and data buffering, while a built-in 500GB hard drive provides long-term storage of the audio archive. This architecture increases system reliability and allows for efficient storage load balancing. Cyclic recording with automatic overwriting of obsolete data is supported, eliminating the need for constant storage monitoring. Effective compression algorithms allow for increased archive depth without loss of recording quality.

The device's compact design ensures easy installation and integration into various systems. The recorder can be placed close to signal sources, reducing interference and improving recording quality. Low power consumption makes it suitable for use in standalone and power-constrained systems.

Additionally, VAD (Variable Actuation Device) recording is supported, allowing for recording only significant events and optimizing storage resource utilization. Data can be downloaded from a microSD card or hard drive for further analysis.

The hardware is built with reliable components, ensuring stable operation over long periods of use. The device is resistant to external influences and is suitable for use in a variety of conditions.

The MDL2-3-8 (32 GB microSD + 500 GB HDD) is used in security systems, control room communications, access control facilities, and industrial installations. The solution ensures reliable recording of audio signals, increases the level of control and facilitates effective event analysis.
