RM-31A QuikWave Audio Player / Message Announcer
RM-31A is a 19” 2U rack mount digital audio repeater system designed for general purpose applications. Up to 12 sound
cards (model number DM-31A, sold separately) can be installed and operated independently. Each sound card has its own trigger input, audio output, and RS-485 serial port. There is also an on-board power relay that’s activated
automatically during the audio playback, so that an optional external device can be control synchronously if needed.
The system supplies a master clock to all cards to keep them in perfect synchronization with each other at all times - 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.
RM-31A has a built-in 110/220 VAC auto-sensing switching power supply with 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) with the mounting brackets removed.
Automatic Time-Triggered Audio Playback
Automatic time-triggered audio playback is possible by controlling the player with an optional TMR-08 Weekly Event Timer. Each weekday may have a different program of events.
Audio Amplifier Module
When the player cannot be placed near the speakers, it may be better to drive an amplifier module installed near the speakers instead of running long speaker wires.
