Redback A 4432 Operating Manual page 7

Figure 3 demonstrates a basic install with eight input sources. The VOX priorities are set for 3 levels of priority, so that the
microphone on input 1 has the highest priority. The input 1 DIP1 switch settings are set for a 100mV sensitivity balanced
microphone input with the priority/VOX enabled which makes this input priority level 1. (Refer to section 7.0 for more
details about DIP switch settings).
Input 2 is connected to a telephone paging system with a line level output. The Input 2 DIP2 switch settings are set for a
line level input with 1V input sensitivity and the VOX is enabled which makes this input priority level 2.
Input 3 is shown with a microphone connected. The Input 3 DIP3 switch settings are set for a 100mV sensitivity balanced
microphone input and with the VOX enabled which makes this input priority level 3.
Input 4 is set as a line level input with a sensitivity of 1V and the VOX priority disabled.
Input 5 (AUX 1 - AUX 4) inputs are all set to 1V sensitivity via DIP 5 and DIP 6.
The output of the mixer is fed into a power amplifier which drives the speakers.
All DIP switch settings are shown below.
