4. SPECIAL APPLICATIONS
4.1 Using The AUTOCOM PRO For Recording And Cassette Duplication
In the recording and duplication field the goal should always be to achieve an optimum recording level onto the
recording media. Too low or too high recording levels lead to side effects such as noise, distortion etc. In
mastering and multitrack recording, as well as in duplication, one should always take care to utilize the full
dynamic range of the tape recorder, DAT recorder etc. Principally, it is possible to control the recording level by
riding faders, which means with low level signals, the gain is increased, whereas the amplitude of high level
signal is reduced. It is obvious that this method is insufficient because, especially in live recordings, the
expected signal levels cannot be anticipated correctly. Especially with multitrack recordings, which are run
under hectic circumstances, the signal level of all channels cannot be monitored and controlled at the same
time. Generally, with manual control, it is not possible to achieve satisfying recording results.
An automatic gain control system achieves better and more constant results. Use the AUTOCOM PRO by
starting with the initial settings, and use its dynamic control functions in order to be able to drive an analog, as
well as a digital recording, up to the limit of its maximum dynamic range while remaining noise- and distortion-
free.
