Selecting RTC and pressing the Ext button will set the time code hours, minutes and seconds from the internal real time clock of the recorder, allowing a very rapid TC setting.
  • Page 73 SIP address which is similar to an e-mail address (e.g. Nagra@sipserver.com). Each device is thus known by the server which allows others to locate it by contacting the SIP server using the SIP protocol, and to subsequently set-up an audio connection between the two parties.
  • Page 74 Method 1: (Preferable choice) is a direct audio communication between devices without going through a dedicated SIP server. A SIP server is required to initially establish the connection but is subsequently bypassed once the connection is made. The direct audio connection using the RTP protocol induces lower delays since the data does not pass through a relay point.
  • Page 75 This name is given by the SIP provider Password: Provided by the SIP provider Server: Name of the chosen SIP server. If this is left blank, the Nagra does not connect Seven to a SIP server and only direct connections are possible.
  • Page 76 This is a prioritized list of available communication compressions. During connection setup the common compression with the highest priority of both parties is selected. To force a compression all fields except one can be left empty. Compression 1: Compression 2: Compression 3: Compression 4: Auth.
  • Page 77 (That you can store in the contacts of the Nagra). The advantage of a SIP server is that the correspondent is logged in (each time he goes on-line) and is therefore sure to communicate with his own IP address rather than changing from each location (From home, work etc).
  • Page 78 VoIP transmission screen / details: The transmission screen shows basic information regarding the network connection (local network connection type and its quality) in the top left corner. In case of an established communication the SIP symbol shows an overall audio link quality from 0 to 5 bars. On the third line, the own SIP identity is shown.
  • Page 79 I.S.D.N. (R.N.I.S) (Hardware option part number 71 19186 000) The Nagra Seven can be equipped with an internal I.S.D.N (R.N.I.S.) transmission codec system for communication via a digital telephone system. The features offered are very complete and allow many different communication possibilities which are all explained in the following pages.
  • Page 80 I.S.D.N. OPERATION Communication using I.S.D.N. can involve various different operations such as making a call, receiving an incoming call, mixing live audio with a previously recorded file, recording a communication etc. so to simplify matters, the various different screens and their operations are explained on the following pages which should cover all areas.
  • Page 81 I.S.D.N. screen When I.S.D.N. is selected and OK is pressed in the transmission screen the principal I.S.D.N. screen will be shown.

  • Page 99: Annex I Alc / Limiter Detailed Explanations

    The headroom of the ALC/LIM and the headroom of the filters are same; the Nagra Seven simply uses the larger of the two. In other words, if the headroom for the limiter is set to 18 dB, and a filter is subsequently selected with a headroom of 24 dB, then the limiter will be active at 24 dB rather than 18 dB.
  • Page 100 You have the choice whether to control this gain with the potentiometer or by specifying a fixed value. When using as limiter, it is probably preferable to use the potentiometer for control. The control will act on the microphone preamplifier gain as if the limiter were not switched on, except there will be the headroom offset subtracted.
