3. In the Audio Inputs/Outputs submenu, select Attenuate Audio Out and set
the attenuation to 0 dB.
4. Also in the Audio Inputs/Outputs submenu, select AES A > Analog Out Map.
NOTE. For the step that follows, note that Option DA does not have outputs
Analog 7 & 8, so you can only set the other inputs listed in the step when checking
Option DA-equipped instruments.
5. In the Analog Output Map, put an X in the Bar 1, 2 position for outputs
Analog 1 & 2, Analog 3 & 4, Analog 5 & 6, and Analog 7 & 8.
