As shown above, the change in the electrical frequency response caused by the use of the SC 93 cable can
be neglected.
Directional characteristics
Note: The way of mounting of the preamplifier (when using the extension cable SC 93) is critical for
the SVAN 979 acoustic characteristics in the free field. Thus, using the tripod and the “gooseneck”
SA 08 is strongly recommended.
