Introduction to the DIR911 
 
The Eventide DIR911 is an instant recall recorder that takes telephone and/or auxiliary inputs 
and stores an incoming or outgoing audio message in digital memory, from which it is then 
immediately available for playback. The standard unit comes with approximately 64 minutes of 
audio storage, with an upgrade to 128 minutes of storage easily installed in the field. The unit 
offers the following features: 
 
• 
Playback speed control, allowing the operator to play back the message up to 50% 
slower or 50% faster without any detectable change in audio pitch. This is invaluable for 
deciphering unintelligible messages 
• 
Software controlled automatic gain control (AGC) 
• 
Caller ID 
• 
DTMF (Dual Tone Multi Frequency) tone detection 
• 
Serial input/output ports for Automatic Location Identification (ALI), Automatic Number 
Identification (ANI), Remote Control, and external time synchronization 
• 
Live monitor output with adjustable volume level 
• 
Playback speaker and headphone jack with adjustable volume level 
• 
Re-Record output with adjustable volume level 
• 
Off hook detection 
• 
External closure record activation 
• 
Optional UPS (Uninterruptable Power Supply) giving 40 minutes of backup power 
(available from Eventide). 
 
Typically, the DIR911 is used to record and then listen to an incoming or outgoing call 
immediately after the call has finished. In public safety applications, for example, when an 
operator receives a call, s/he may need to replay the call a few times, to make certain of the 
essential information before any action is taken. With the DIR911's adjustable speed control, the 
operator can speed up or slow down the message to make it intelligible (useful when the caller 
has been panicked and is inaudible at normal speed). In addition, the caller’s phone number 
and location are available to the operator. 
 
The information contained in this manual is for technical setup of the Eventide DIR911 
unit.
