On this board the master data bus reaches its
end. Here, all control signals and voltages are
produced with which the master controls the
audio routing, the Wersivoice settings,
volume levels, etc.
The digital information for the control v6ltages
is applied to the inputs of the DAC 0832 (IC
5) in multiplexed digital form and are
converted into a corresponding voltage
potential. This voltage potential is routed to
the correct output by the de-multiplexer IC
13 (4051) which is controlled by IC 14 (HC
174), is stored in a
Sample & Hold and adjusted to the correct voltage level.
The remaining board consists of 5 output ports (IC 6-
IC 8, IC 15 and IC 16) which generate the control
signals, as well as an input port IC 20.
