To prevent overload of the following device:
Adjust the Oscillator to +16 dBm or more. Adjust the Pk Threshold on the STC-8 for 12db of
gain reduction. Use this as the maximum output from the STC-8. Then adjust the input level
on the DAT Machine to a point just below overload on the DAT Machine. Leave a safety
margin of about 1/4db if you can. The ratio gets greater than 10 to 1 but is not infinite.
If you find that you need more make up gain when using the compressor, you can adjust the
STC- 8 gain controls and the DAT will still be overload protected. If you increase the
input gain on the DAT Machine you will no longer have overload protection.
Increasing the gain controls on the STC-8 will increase the ratio of the limiter, but not
affect the compressor. If you find that you have too much Pk Limiting going on, you have 3
options to deal with the situation;
(1) reduce the amount of make up gain on the STC-8. Reducing the make up gain will not
affect compressor operation.
(2) increase the amount of compression that is taking place, or
(3) reduce the input level.
Any of these changes will allow you to remain overload protected.
The more you know about your gain structure, where the overload point is, and what your
average signal level is, the easier it will be to get maximum level without overloading
your digital machine.
