Figure 17. AC/DC-coupling and Mix
Speaker-Attenuator stage
Each of the four speakers and the subwoofer output has a separate volume control in the
range: +15... -79dB plus mute with a typical value of -90dB.
Output Mixer
A Mixing-stage is placed after each speaker gain/attenuator stage and can be set
independently to mixing-mode.
Having a full volume control for the Mix-signal in the range:+15... -79dB plus mute with a
typical value of -90dB, the stage offers a wide flexibility to adapt the mixing levels.
