Digital Message Announcer DMA-1 Solid State Digital Audio Player Applications: • security warning messages • voice alarms • music files • commercials DMA-1 Application sites: • cinemas • theatres • hotels • railway stations • shopping centres • trade shows • museums DMA-1 DMA-1 is an high technology device. It houses in a very compact space: • • • • • MP3 Audio player ; D-class stereo power amplifier 20+20W or mono (bridged) 40W; 8 inputs for single, sequential or binary combination audio messages play. 1 RS485 serial control port; Audio mixer to mix an external audio source. DMA-1 DMA-1 Totem The audio message invites to select an option Exciter IR proximity sensor DMA-1 Totem Reproduced message Exciter Touch sensor DMA-1 Plus: • • • • • Very high audio quality. High storage capacity. The recorded music/spot quality is maintained through time. Hardware reliability: DMA1 has no mechanical moving parts Removable memory card enables quick audio files update. DMA-1 Plus: • • • • Easy, quick and intuitive audio files management. File plays Instantly regardless the audio track store point. DMA1 does not requires any specific software to store and manage audio files. Free configuration software (GUI). DMA-1 DMA-1 Technical Characteristics: • • • • • • • • Mains voltage 12÷15VAC o 12÷24VDC 6/8 multi-purpose inputs for single, sequence playlist or binary combination playing. Activation with programmable state 0 or state 1. V-link programmable output. Preamplified L+R stereo audio input for external music source, mixable with MP3 audio. Preamplified L+R stereo audio output (0dB). Amplified stereo audio output 20W+20W or mono 40W with jumper (bridge, 4 ohm. 1 serial communication port RS485 for external control systems interfacing . 1 REMOTE connector for external SD/MMC and command buttons connection. DMA-1 Technical Characteristics: • • • • 4 buttons: play, stop, track forward, track backward and output volume setting. 1 Red LED: power on. 1 Green LED: play/standby. Configuration parameters setting and storing on the memory card. DMA-1 Technical Characteristics: • • • • • • • Compact size: 102x102x18 mm. DIN rail compatible via a proper accessory. Memory types: SD and MMC. Formats: MPEG1 layer 3 (64 to 192 Kbps). Frequency response: 20 ~ 20.000 Hz (±3dB). Signal/noise ratio:> 90dB. Harmonic distortion:<0,1%. DMA-1 Progammable functions: • • • PLAYLIST: operation with several playlists which can be activated by logical inputs. SLAVE: 8 digital inputs to play up to 255 audio files in binary combination. SERIAL RS485: to interface with control systems for direct recalling of any audio file stored in SD/MMC memory DMA-1 Progammable functions: • Audio announcement sequences cyclically issued, consisting in single files or 8-file blocks, with 60mins. Max of programmed sequences. • DMA-1 has an audio input to connect external music sources: at the scheduled event the audio input fades out as per programming. DMA-1 Special functions: Connecting two DMA1s in cascade via the V-link connection and the audio inputs/outputs can recreate the typical operating mode of a commercial radio station. One DMA-1 (A) is programmed to run in playlist mode, to play the music content (PLAYLISTS.TXT). A The other DMA-1 (B) is programmed to run according to a schedule (PALIN.TXT) to play commercials and\or announcements. B V-Link automation example: DMA-1 (A) goes on standby after the completion of a Music file. DMA-1 (B) starts to play a commercials according to the timer config. DMA-1 (A) starts to play the following MP3 music file in the playlist. Enjoy working with the DMA-1!
