LF CONNECTION
Pre-emphasis setting “PR:”
Low frequency and stereo channel signals have to be adequately "pre-emphasized". For
this purpose, select the setting “PR” and choose 0, 25, 50, and 75
μ
s. Factory preset is
50
μ
s. (Europe/Pacific/South America). USA requires 75
μ
s. When using an external
processor that employs pre-emphasis you must set the “PR” to 0.
If you need to alter the setting, select and adjust the “PR” to the required parameter.
LF wiring and impedance selection
The STL10 Series supports
balanced/unbalanced signals with selectable
input impedance.
The audio inputs can be set to 600/10K
ohm resistive impedance; factory preset is
10k ohm. They can be connected to the
balanced output of a professional mixer or to
the unbalanced output of a low cost unit
without appreciable degradation.
Selection of the input impedance is done
by jumpers JP1 and JP2 on the input board
