also light the LED, when process CV or when DC is not otherwise a concern. Flip
down for AC coupling, which turns the LED off, to remove any DC bias from the
signal and protect speakers.
In case you have not heard the speaker thing before, a DC signal present in
a signal can (and eventually will ) damage a speaker receiving it. Speakers are
driven by a coil that generates a magnetic field. This field then reacts with the
magnetic field generated by the large magnet around the coil. The coil field is
generated by current travelling through the coil, and a DC bias causes current to
flow when it normally would not, which increases the generated field strength and
causes the coil to work harder than it should. This can often exceed the intended
limits of the speaker and burn out the coil, warp the coil, overextend the cone
travel and damage the support web, or all of the above.
tl;dr: don't drive a speaker directly from Sinner in DC mode. Sinners are
known for doing bad things.

Looking at the rear of the module, the negative supply (red stripe) is on the
left, positive supply is on the right (see fig.8).

Power
The power connector header is a 2x5/10-
pin shrouded box header which accepts the
standard Doepfer power cable. This header style
is polarized, meaning the connector can only
be inserted one way, to prevent connecting the
power backwards and damaging the unit.
This assumes that you are using either the
supplied cable or one manufactured by Doepfer.
