Thelevel of the messages can be set via the message volume control (2).To fully benefit from the features of the message manager in the overall Plena system (e.g. to distribute pre-recordedmessages to pre-programmed zones) the unit must be connected via the system pre-amplifier LBB1925. To do this,use the RS232 cable and the audio cable supplied.There are several ways to connect the message manager to the system pre-amplifier:- Connecting the Cinch output (4) of the message manager to the Cinch PC Audio In (R) line input of the systempre-amplifier, as shown in figure 3.2 (in which the LBB1961 functions as a BGM source).- Connecting the XLR output (6) of the message manager to the points 1 and 3 of the 8-pole DIN socket of thesystem pre-amplifier.3.3 Loopthrough audio connectionsLBB1920Dir.Out1 Dir.Out2 Dir.Out3 Dir.Out4 Ins/ Casc / Emgln Ins/ Casc Out Master Line Out Master Mic.

However, whenthe message manager becomes active, this loopthrough connection is interrupted and the message manager isswitched to the power amplifier.Figure 3.3 shows this configuration example in which the Plena Mixer Pre-amplifier LBB1920 is used with a PlenaPower Amplifier LBB1938. This is a high priority application, as the message manager has absolute priority.Bosch Security Systems | 2003-09 | 9922 141 50502en
