Rohde & Schwarz SR8000 Series - Setting Input Impedances for Analog AUDIO; Setting the Audio Parameters

Chapter 4 Putting into Operation
5300.9677.72 - 4.16 - EN-4
when music continuously alternates between loud and soft, and enables an announcer to
speak over it.
Note In MPX mode (input 2 or input 3) the MPX power limiter is always deactivated. In this case
the external source must ensure compliance with the ITU recommendation.
2.3.4 Setting the Audio Parameters
2.3.4.1 Setting Input Impedances for Analog AUDIO
1. Select Transmitter > Exciter > Input > Analog Audio.
The Analog Audio window opens.
2. Set the parameters as shown in the table below.
Setting item Description
Impedance Selection of the input impedance; possible settings:
– 600 Ohm
–>2 kOhm
Level Setting the nominal input amplitude
Value range (analog): -6 dBu through +12 dBu (default setting +6 dBu)
Value range (MPX): -1 dBu through +16 dBu (default setting +6 dBu)
Threshold Setting for the input amplitude threshold for monitoring
The setting can be entered in two ways:
– as a percentage of the nominal input amplitude
in the value range: 2% through 80% (default setting 5%)
– as an absolute value in dBu
in a value range dependent on the absolute level, corresponding to
input as a percentage
