Added the PRESETs: there are 2 types of presets and all are selectable from the menu MAIN>PRESET

Added RESTORE FACTORY

Added new compander:
 COM-Wisy 50K (for compatibility with Wisycom intercom receiver with NR compander and 50K channel spacing)
 NONE-d50 and NONE-d75 (for compatibility with receiver without compander and 50μs/75μs of -de-emphasis)
 COM 12k5 (for compatibility with Wisycom or other brands of intercom receiver with no compander and 12,5KHz channel spacing)
 COM 250k (for compatibility with Wisycom or other brands of intercom receiver with no compander and 20KHz channel spacing)

Added the activation code:
To enable companders/modes on the customer premises without returning the transmitter to Wisycom factory contact Wisycom staff which will supply the special key (serial number depending) than you can manually enter through the menu Advanced>Act. Code or with the Manager.

Changed: Simplify the layout of the menu (see the Tree Menu for more details)

Changed:  the audio gain settings: we split the audio gain Left and Right and add the Modulation gain, in order to give more margin during the gain setting especially when the input audio stereo is with 2 traces with different dynamic

Added Equalization OFF (to disable the equalizer) and Flat (to reset the equalizer)

Added the compander info during the SYNC:
During the sync RX <–>TX, the RX passes also the compander.
– if SYNC RX->TX then the transmitter adapts automatically the compander settings (Mode)
– If SYNC TX->RX then the trasnmitter inform with a WARNING in case of compander mismatch

Added the receiver SYNC function to pass the Receiver parameters from TX to RX for MPR50-IEM and MPR30-IEM

Changed Activate the audio bar even when the transmission is OFF

Added compatibility with 250Hz or multiple (12.5kHz, 6kHz, ..) for compatibility with intercom system:
