(„ : in / output connected)
H The switches are bi-directional, so swit-
ching can take place from four inputs to one
output, or four outputs to one input.
Which process is happening at any one time
will always be clear from looking at the mo-
dules connected.
H Any signal from -8 V to +8 V at the O/I resp.
I/O sockets can be processed by the A-151.
Voltages less than -8V or more than +8V will
lead to malfunction of the module ! It is
possible to modify the module so that volta-
ges in the range 0...+12V can be processed.
You find a modification of the A-151 for
signals in the range 0...+12V on our web site
www.doepfer.com in the FAQ section (click
to the FAQ button on the left side of the
page).
H Another solution for signals beyond -8V resp.
+8V is to attenuate and/or to change the
offset voltage of the signal. The A-129/3
attenuator/offset generator can be used for
both purposes.
H From version 2 of the module (from about
2005) the full voltage range of the A-100 (i.e.
-12V...+12V) can be switched without any
modification. Version 2 can be identified with
the additional switch 5 Steps.
