-
Here you choose between 4 different modes of operation for the HERCHILD Model 670.
•
The first being ´
IND
´ and refers to each channel being individual with it´s own independent control.
•
The next, ´
LINK
´ will tie the channels together and base the compression applied on whichever channel is producing
the most compression to be used for both channels. This is used for stereo operation.
•
The ´
LAT VERT
´ takes us way back to the vinyl cutting days and refers to the lateral and vertical adjustments when
cutting grooves onto vinyl records. This is similar to what we refer today as Mid & Side. A very effective way of
widening a stereo image and improving and strengthening the center image. Here the upper channel of the
HERCHILD Model 670 controls the ´Side´ information and the lower channel controls the middle or ´Mid´ information.
•
´
LAT VERT
LINK
´ is the same but with the controls linked together, once again deriving the overall compression
from whichever channel is producing the most at any given moment.
