Peripheral connections
In addition to the direct line and microphone inputs on the AMP523MK2, additional wall
line and microphone inputs can be connected. It provides the possibility for connecting
one additional wall line input unit (WLI) and one additional wall microphone input unit
(WMI). For controlling the standard functions like input selection and general volume
control, an additional MWX45 wall panel can get added to the system.
The additional units must be connected to the “RS485 + AUDIO” RJ45 input connection.
The data transfer between both audio input units and the control units is done over a
single CAT5 (or better) cable. The wiring should be straight, according to the wire colour
coding as shown in “Chapter 1: Pin connections and connectors” of this user manual.
The signal coming from the wall microphone input is combined with the direct
microphone input and priority settings also affect the wall microphone input signal.
Both inputs are mixed and the volume for each channel can be set separately by using
the fader on the web-based user interface.
The wiring between the different units simply needs to be linked-through.
An example diagram of how the system including the additional wall audio
inputs and control panel should be connected is shown in the diagram below.
