INTRODUCTION

DAR (

Digital Audio Recording system

) has the capability to record and process conversations, 

executing a digital audio processing to deliver a higher quality.
DAR records conversations from 1 to 4 audio inputs simultaneously and stores them in an 

internal memory. All the conversations are stored during a week time for each audio input 

and, once the maximum storage capacity has been reached, it starts to rewrite the oldest 

recordings first, and so it records in a continuous loop. The equipment accepts different 

audio input devices, such as B&G microphones or B&G intercoms.

DAR can be set to record at specific time schedules; otherwise, DAR records continuously by 

default, even when the intercoms are off.

The equipment includes a software for recording management, where the recorded audios 

can be filtered by date, played, and downloaded. For the equipment and software to function, 

both the DAR and the computer executing the software need to be connected to the same 

computer network (LAN).

INSTALLATION

Before installing the DAR, make sure that the audio input device to plug in (intercom or 

microphone) is properly installed and operational.
Depending on the input device to connect with the DAR, locate the audio wires and perform 

all the required junctions, as explained on the next page.

If the wire’s length is sufficient for the installation space, connect them directly to the DAR; 

otherwise, add more wire and do all the jointing. Take the recommendations into account to 

avoid affecting the input device’s correct operation.

NOTE:

 Avoid connecting the red’s 

shield to the white’s shield to prevent 

introducing noise into the recordings.

Once you have done all the needed wire joints, follow the installation procedure.

Installation procedure

When selecting the place where the DAR electronic unit is to be installed, make sure that 

there is a nearby network point.
1.  Connect the 3.5 mm stereo plug 

coming  from  the  audio  input  (LTG, 

LTC  or  microphone)  into  one  of  the 

DAR’s audio connectors.

2. 

Connect the UTP cable to the nearest 

LAN port.

3.  Connect the 5VDC power adapter to a 

110 or 220VAC power outlet.

4. 

To turn on the equipment, press and 

hold the power button (5 s) until the 

power  indicator  blinks.  The  power 

indicator will stop blinking once the 

DAR has started up correctly.

5. 

To turn off the equipment, press and 

hold the power button (5 s).
