2.3 ALARMS AND AUTOMATION In case of alarm the red LED lights up and the icon of a bell appears in the upper bar of the display. If the alarm disappears, the red LED is turned off and the bell starts blinking, in order to show that an anomaly occurred. To know the details of the anomaly and when it occurred, the history menu can be used. Once this menu is accessed, the blinking bell icon disappears.
« Forward & Reflected Power If the value of the forward power exceeds the threshold value (factory setting) the amplifier is switched off and the event is recorded in the alarm history. « No communication with the boards on the BUS No intervention. The history records the event only if Polling is enabled. If Polling is disabled, the ‘No communication” is not detected. « Non-corresponding standards There is no intervention in case one or more boards on the BUS are set to work on different standards.
MILT. AUDIO MONO MODULATOR MODULE MTGO071ARG DESCRIPTION The audio signal enters the module trough one 600€2 balanced or 10k(2 unbalanced XLR connection, which may be placed either on the front or rear panel and software-selected. It is conditioned by a digital power-meter with a £8dB dynamic and muting, Then there are the emphasis and clipping stages (which can be inserted via software), before the frequency modulation of the audio carrier.
The module contains the following blocks: Input relay — chooses the audio source between the XLR on the front panel of the module and the one on the back of the apparatus and selects the input impedance to 60002 or 10k; both switching are managed by the software. Audio level regulation stage — regulates the level of the audio signal by means of a digital potentiate which can be programmed trough a u Wire interface (with 0.5dB step between -8dB and +8dB).

The selection of the input impedance is made by means of a relay, the adjustment of the input level is made by means of a digital power-meter.
