Product Description

DigiStor-MP is a 99-message MPEG digital audio recorder that can store up to 20 minutes of monaural audio with a bandwidth of 15 kHz. DigiStor-MP’s multiple modes of use make it ideal for numerous applications in broadcasting, telecommunications, and commercial sound: network news delay, station or translator ID and local insert, message-on-hold, news and actuality lines, call-in telephone information, museum exhibits & displays, sound effects, announcements, etc.

DigiStor-MP can store up to 99 messages which can be random-accessed and played in any order. Multiple playback modes support one-time or repeat play, plus automatic sequencing and message “stacking.” Messages can be different lengths, and can be selectively recorded (or changed) without having to re-record other messages. Messages are stored in non-volatile flash memory and are retained even if power is off. (No backup battery needed.) Recording and playback is via local or remote control. The first 8 messages are remotely accessible via GPI interface (contact closures). All 99 messages can be accessed either locally or remotely via an optional GPI interface, and can be recorded and played via the integral RS232 interface. DigiStor-MP can record from either a mic or line level source. The unit records audio in MP3 format, but can play MPEG files recorded in Layer I, II, or III formats. MPEG files recorded on a PC can be imported via RS232 for playback.

Two relays are included for control and message signaling. The primary relay can be programmed to either remain closed during message playback (or record), or generate a momentary pulse at the end of playback (“Auto-EOM” mode). The secondary cue relay can be programmed to generate a momentary pulse at any time during or after any message playback. An optional automatic tele-coupler permits DigiStor-MP to be connected to a phone line for auto-answer and message playback to a caller. DigiStor-MP can be rack-mounted with the optional rack mount kit.
