The
A-132-4 contains four identical voltage controlled amplifiers (VCA)
with exponential control scales. Each VCA has two control voltage
inputs (C1, C2), a signal input (In) and a signal output (Out). The
control voltage inputs C1 and the signal inputs can be normalled by
means of internal jumpers, i.e. the corresponding input signals of
unit #1 can be connected to the switching contacts of unit #2. Those
of unit #2 can be normalled to unit #3 and those of unit #3 to unit
#4. If the normalling is not desired the jumpers have to be removed.
In addition the sum of all four outputs is available (bottom left
socket with the sum sign). Therefore unit #4 has only one control
voltage input (only C1, no C2). If desired this socket can be
jumpered as control voltage input 2. But then the sum signal is no
longer available as a socket (only as an internal pin). For each VCA
output a jumper is available that determines if the output signal of
the corresponding VCA is added to the sum signal. From the factory
all four jumpers are set (i.e. all four VCA output signals are
added). By removing of one or more of the jumpers one can choose
which VCA output is added to the sum. The jumpers can be replaced by
switches too |
