3. Indicators
1 LED ... 2 LED
LEDs 1 and 2 serve as status indicators, to show
which of the two in / outputs " and § is at that moment
connected to the common out / input $.
4. In / Outputs
! CV
Socket ! is the input for the digital control voltage,
whose level determines the switch state (see Fig. 1):
• CV low ( < ~3.6 V): O/I ---- I/O 1
• CV high ( > ~3.6 V): O/I ---- I/O 2
If a high frequency control voltage is used for swit-
ching, audio frequency modulation results (see Fig. 4
on page 5).

" I/O 1 • § I/O 2
These sockets are the in / outputs.
$ O/I
Socket $ is the common out / input. Depending on
the level of control voltage at input ! it’s connected to
socket " or § (see Fig.1).
