Fuse 2A, 250V, 5 × 20mm slow melting 2 pieces
DC backup battery 12V/7Ah (two in series) or 1 set of 24V battery pack
Speaker line monitoring terminal resistance 10k Ω, 2W metal film 8 pieces
2 noise detectors HN-D32N (depending on configuration)
1 power amplifier (backup) and system matching model (such as X-PA240) (if N+1 redundancy is used)
6.3 Software Configuration Backup
All configurations of DCS (partitioning, routing, scheduled tasks, priorities, etc.) are stored in internal memory. It is recommended that engineers back up the configuration file to the PC through X-SMART software after each configuration modification. Once the device's main control board is damaged and needs to be replaced with a new machine, the configuration can be quickly restored, avoiding the tedious work of reprogramming for hours.
