2. Audio Inputs
3. Paging Station and Microphone Inputs
Balanced Audio Inputs
Use these inputs to connect balanced audio signals.
The correct input sensitivity can be choosen with the selector switch next to the Phoenix
connector.
In the LINE position the input sensitivity is 350mV, while in the position MIC it is 5mV.
To operate mics that need phantom power shift the switch into the PHANTOM position.
Input sensitivity is also 5mV in this position.
Unbalanced Audio Inputs
Use these inputs to connect unbalanced audio signals.
The input sensitivity can choosen between 195mV and 2V by using the gain control next
to the RCA inputs.
The input impedance of this inputs is 47kOhms.
Connectors for Paging Stations
At these inputs the paging stations UPM 8808 can be connected.
The volume of the paging signal can be adjusted by the gain control next to the relevant
RJ 45 connector.
You find further information regarding operation and configuration in the operation manual of the
UPM 8808.
Mic Input
At this input a dynamic microphone can be connected.
The Mic signal will be routed into all zones.
The input sensitivity can be adjusted in a range of 5mV – 300mV by the GAIN control.
The HI / LO tone controls allow an alignment for an optimum of sound quality.
The input impedance is 600 ohms.
A priority for this input can be alternatively activated for each zone.
