typical program material at normal levels.

If the STL uses preemphasis, its input preemphasis network will probably
introduce overshoots that will increase peak modulation without any in-
crease in average modulation. We therefore strongly recommend that
the STL transmitter's preemphasis be defeated (freeing the STL from such
potential overshoot), and that the 464A be used to provide the necessary
preemphasis.
We recommend 8-15 dB gain reduction for most formats.
If the STL transmitter's preemphasis cannot be defeated, configure the
8200ST for flat output. In this case, average modulation levels of the STL
may have to be reduced to accommodate the overshoots.
Quick Setup guides you through 6300 setup. It is appropriate for users without spe-
cial or esoteric requirements. Following this section, you can find more detailed in-
formation regarding setup beyond the Quick Setup screens. In most cases, you will
not need this extra information.
Quick Setup assumes that your 6300 will be driving flat channels because this is the
most common scenario. If you need it, you can turn on pre-emphasis after you com-
plete Quick Setup.
For the following adjustments, use the appropriately labeled soft button to choose
the parameter you wish to adjust. To change a parameter (like an output level), it is
usually necessary to hold down the soft button while turning the knob. However, if
there is only one parameter on a screen, you can change this with the knob alone.
(You do not have to hold down a button.) Let the text on the screen guide you
through the process.
1. Press the front-panel Setup button.
2. Press the Quick Setup soft button when its label appears on the display.
Quick Setup presents a guided sequence of screens into which you must insert in-
formation about your particular requirements. In general, the screens are self-
explanatory.
