Output Selector and Mixing
The output-selector allows different sources to connect to the front output. The setup of the
output selector is shown in
Figure 16
. A Mixing-stage is placed after the front speaker-
attenuator and can be set to mixing-mode.
In normal mode, switch (sw1) turns to down and main signal is directly outputted through
front pin. In the mixing mode, switch (sw1) turns up, mono differential signal and main signal
are mixed with ratio -6/-6dB. Having a full volume-attenuator for the mix-signal, the stage
offers a wide flexibility to adapt the mixing levels.
