Pan In
This socket is the audio input of the Panning sec-
tion. It is internally connected to the VCA output /
(normalized socket) provided that no plug is inserted
into the socket (.
)
CVP1 • CVP2
These are the control voltage inputs for the Panning
section. The control voltages of both sockets are
added to manual control 8.
CVP1 is equipped with an attenuator that allows con-
trol the level of voltage - the intensity of panning
modulation - with the attenuator 9.
Socket CVP2 does not have an attenuator. The vol-
tage range for this input is approximately 0...+5V.
A typical application is the periodical "walking" of a
signal in the stereo panorama. For this the triangle or
sine output of a LFO is connected to one of the sockets
)
to control the panning.
=
Pan Out L • Pan Out R
These sockets are the left resp. right audio output of
the panning section.
5. User Examples
Module A-109 makes available three important basic
modules: 24dB low pass (VCF), VCA and PAN. At
least VCF and VCA are required for most of the
standard synthesizer patches. The sub-modules are
usefully pre-patched to minimize the required external
patches.
Because of the normalized audio input sockets the
sub-modules of the A-109 can be used even separa-
tely from each other.
As the A-109 is nothing but a collection of modules that
are still available in the A-100 please look at the
examples in the manuals for the A-100 filters (e.g.
A-102, A-103, A-105, A-108, A-120, A-122), VCAs
(e.g. A-130, A-131, A-132) and the separate panning
module (A-134) to find some typical applications.
