DSW104+modular integrated audio intelligent switching device, with network monitoring and remote management functions, suitable for emergency switching of multiple backup and one backup transmission links in broadcasting centers, transmission stations, and live broadcasts, as well as audio broadcast switching of multiple signal sources.

• Three external signals can be customized as digital or analog inputs, forming an intelligent 4-to-1 configuration with one internal digital pad. In addition, it has analog and digital outputs, eliminating the need for analog-to-digital and analog-to-digital conversion, and providing higher flexibility in configuration
  Equipped with IP network interface, supports remote monitoring, and can monitor the overall operation status and input/output signal sources, including signal level, phase, display of abnormal information, and real-time network monitoring
  Equipped with shutdown, clipping, drop, AES lock loss, inversion, and comparison alarm functions, it can set alarm parameters and time limit control as needed. Parameter storage and alarm calculation are completed internally in the device, without relying on the network
  Four priority levels can be preset arbitrarily, and corresponding alarm items can be selected to confirm whether automatic emergency switching is performed, and whether to automatically switch back to the original channel when the signal with high priority is restored. Manual switching can also be selected at any time
  The monitoring of output signals adopts a mining method to ensure the authenticity and reliability of the monitored signals, and to eliminate the phenomenon of false monitoring
  When the external signal is interrupted, the internal cushion music signal can be automatically enabled for playback. The internal cushion music adopts solid-state chip storage, supports S48 format files, can loop playback, and can be downloaded from USB
  Abnormal logs are recorded in the local memory for local viewing or remote access
  Built in high-precision real-time clock, capable of timing through the network
  The effective time limit for normal device switching can be specified to avoid non broadcast time periods. The time limit table cycles once a week and can set 5 working time periods per day, supporting cross zero connection
  The synchronization method supports internal synchronization (48K) and external synchronization (32-96K)
  The panel is equipped with local monitoring output and supports manual selection of monitoring signal source (input or output)
  Provide network monitoring software to achieve remote monitoring of device status and remote control of panel operations
