VC2 7
The amount of compression in use can be seen from the VU meter; but also the
flickering red LED is fitted to show the depth of compression;-this is particularly useful
during a busy session!
STEREO LINKING
On some units only a stereo link socket (phono socket) is fitted to the rear panel. To link
two units fit a screened single phono to phono cable between the two link sockets. This
will link the two compression sidechains BUT DOES NOT GUARANTEE ACCURATE
GAIN REDUCTION between the two channels. The reason for this is that the
photoelectric compressor relies on the linearity of selected light dependent resistor cells
which are never exactly the same. It is likely that stereo matching of within 1dB can be
achieved with any two units but this cannot be guaranteed. When using the units as
stereo pairs, make sure that the settings on the two units are the same.
CONTROL EXPLANATIONS
'COMPRESSION' simply adds gain to the compression sidechain and so increases
compression. In simple terms this changes the 'threshold' of the compression although
with this compressor the 'threshold' is not clearly defined; the compression starts very
gradually and the compression ratio changes radically with programme content and
amplitude. For practical purposes, winding up the compression control increases the
amount of compression. In use, all controls are interrelated.
'SLOPE' This switch controls the ratio of compression. In practice, 'COMP 2 is very
gentle compression while COMP 1 can give 'pumping' effects. It is advisable to keep
compression to a minimum during recording. The most effective way of using
compression is during the mixdown process.
