7.2.1
Title Bar
The title bar of the window shows the device model (FLX-E-80-4-LZ Dante), the name given to it in the Set
System Configuration drop down on the system status screen, and the IP address including the port number
(192.168.100.226:5000).
7.2.2
Menu Bar
Below the title bar is the menu bar. It contains two
items: File and Help. The File dropdown has 5 options:
Open Configuration, Save Configuration, Save
Configuration As…, Restore Default Settings, and Exit.
Using these commands, a configuration (including all 10
presets) can be saved and later opened and sent to a new
device or to refresh the configuration of an existing
device. This is useful when a number of FLX-E devices are
to be configured identically (Save Configuration), or with
minor changes (Save Configuration As…). When a saved
file is opened, it is immediately sent to the device to
update its configuration. Restore Default Settings resets all DSP parameters to the factory default.
The Help dropdown provides version information for the model DSP.
7.2.3
Device DSP Configuration
The top of the device DSP configuration window shows the status (connected) and the PRESET SELECTION
(Preset 0) for the device. There are 10 presets (0 through 9) to be configured as desired. All signal
processing elements can be customized for each preset. Presets can be changed by selecting the preset in
the dropdown or via the RS-232 or equivalent IP-based command.
Immediately below the status and preset information are two temperature indicators. These indicate the
board temperatures near the MCU and the amplifier IC. Warning thresholds can be set from the System
pulldown menu (Set System Configuration on Selected Device) on the system status screen. If these
temperatures exceed 70C, the amplifier is not receiving sufficient cooling.
7.2.4
Processing Blocks
The signal processing is fixed, and cannot be dynamically changed. There is 24 dB of headroom in the signal
processing chain. Any signals above 24 dB on the signal meters will be clipped. The maximum output from
the DSP (into the following power amplifier) is 0dBV. It is recommended that the limiter block (in
conjunction with the final gain block) be used to ensure that the signal level remains below 0dBV at the DSP
output.
The function of each block is presented below.
