Audio 1 output
Structure When you press the Program shortcut key and the right arrow key twice the “Audio
1 output setup” menu appears. If you have installed an audio module in option slot 1
a similar menu is displayed in the option slot menu to the right of the audio 1 output
menu.
Each parameter is described in the following. For instructions on how to edit the
parameters, see Navigating and editing, p. 39.
The menu has the following structure:
Audio 1 information Display Bit rate: 64, 128, 192, 256 or 384 kbit/s.
Mode: Stereo, Joint, Dual, Mono.
Description Displays the bit rate and mode as selected in the encoder.
Audio 1 interface Parameters Analog, Digital.
Description Sets the output interface of audio 1 to analog or digital.
Audio 1 output gain Parameters -6 to 24 dBu.
Steps 1 dBu.
Description Sets the gain on audio 1, when analog interface is selected. You
typically set the output gain to the same value as the clipping level
in the encoder, so that there is 0 dB gain through the system. If
you want a gain of say 6 dBm through the system you increase the
maximum level by 6 compared to the value in the encoder. The
legal range is from -6 to +21 dBm for 600 Ω output impedance
andfrom-6to24dBufor<20Ω.
