If you are using the
Sx
A
two-way system with a microphone and a line input
simultaneously, it is simple to balance the two signals. The microphone level control has
enough gain and range so that it is possible to mix the mic input and the line input. Once
the balance between the line and mic inputs is set, simply turn the Gain Master control to
the desired level.
·
If there is no sound, keep the overall system gain at a reduced level until you determine
what the problem may be. Typically, a mixer mute switch may be engaged or a
microphone that is switched off is the source of the problem. Keeping the system gain at a
low level will allow you to troubleshoot the problem and let you hear the results without
unexpected bursts of sound or howling feedback. Start with the low-frequency and high-
frequency EQ controls set in the flat position (12 o’clock, middle position) and listen to
your program material before making any changes. Be aware that boosting EQ requires
additional amplifier power and may reduce the acoustic output potential of the system
somewhat. Use EQ judiciously.
·
To route the signal to additional
Sx
A
systems, simply hook an XLR-type cable from the line
output connector on the source system to the line input connector on each additional
Sx
A
system. The signal can be cascaded into a large number of
Sx
A
systems without
degradation.
·
When turning your system off, turn off the
Sx
A
systems first. This will prevent any turn-
off transients from other pieces of equipment from being amplified.
