Sync-a-Gang TechnologyTM
The system runs all cards inside with a master clock and keeps them in perfect synchronization with each other for however long the file playback lasts - a crucial requirement in many applications.

Other than the master clock, the cards operate totally independently with each other. Each card has its own input and output. For your convenience, the chasis also provides a common connector for the RS-485 interface.

RM31A has a built-in 110/220 VAC auto switching power supply with a detachable power cord. The two mounting brackets can be removed if the system is not to be rack mounted. Physical dimensions are 17.3” (L) x 7” (W) x 3.5” (H) without the mounting brackets.
