2.2 POWER CONNECTIONS
A DC socket and a 2 way terminal have been provided for 24V DC input.
The DC socket is for connection of the supplied plugpack which comes with a standard 2.1mm jack connector. The socket
also has a threaded connector so that the Altronics P 0602 (shown in FIg 2.4) could be used. This connector eliminates
accidental removal of the power lead.
The 2 way terminal is for connection of a backup power supply or battery.

2.3 AUDIO CONNECTIONS
Fig 2.5 demonstrates a simple example of the A 4435 in use in a department store. The XLR output of the mixer is fed
into an amplifier which in turn connects to speakers throughout the store. A background music (BGM) source is fed into
the line level RCA's of input 2. A microphone at the front desk is connected to input 1, and has vox priority turned on via
the DIP1 switches. Any time the microphone is used the BGM will be muted. A security message is played randomly, set
off by a timer which is connected to trigger 1 and plays an MP3 "Security to the front of the store". The paint section in
the store has a "Assistance Required" button, which when pressed activates trigger two and plays an MP3 "Assistance re-
quired in the paint section". The output of the mixer is connected to a recorder which keeps a record of everything output
from the system including anything said into the microphone.
