Setting up the analog audio output

To set up the analog
audio output
From this picture you set the output impedance and the output level.
Do as follows to set up the analog audio:
1. From the Codec Explorer right-click on the icon representing the audio you
want to set up and select Properties.
ROSA automatically displays the audio mode of the signal.
's audio output impedance to 600 Ω or <20 Ω.
2. Set the S
TELLAR
You set the output impedance to the value required by the equipment connected
. Typically you set the output impedance to 600 Ω if the input
to the S
TELLAR
impedance of the external equipment receiving the output is 600 Ω. Set the S
's output impedance to <20 Ω if the external equipment receiving the output
LAR
is high impedance (>12 kΩ).
3. Set the maximum output level.
You typically set the maximum level 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 and from -6 to 24 dBu for <20 Ω.
4. Click Apply.
