DTMF SETTINGS
There is a standard DTMF decoder built into DB8000 and connected to the MAIN Input.
Symbols that can be used are the standard ones for any DTMF decoder: – 0-9 figures, ‘A’ through
‘D’ letters and the special symbols * and #. By applying DTMF codes, the Backup Signal Sources
can be controlled. Codes that are used are “Start” and “Stop” and the following operations can be
performed:
- Aux Stat Code – the Aux Input Source will be activated and connected to the Output Circuit
of DB8000;
- Aux Stop Code – the Aux Input Source will be deactivated and the Main Input Signal Source
will be connected to the Output Circuit of DB8000;
- MP3 Start Code – the MP3 Player will be activated and connected to the Output Circuit of
DB8000;
- MP3 Stop Code – the MP3 Player will be deactivated and the Main Input Signal Source will
be connected to the Output Circuit of DB8000;
Please note there must be no coincidence between the codes for any of the above operations.
It must be noted that the Silence Detector (see Silence Detector) will be switched off anytime
there is a DTMF Start Code sent to any of the Backup Signal Sources. The Silence Detector will
be activated back again at the time a DTMF Stop Code is received.
