Electro-Voice SxA Series - Two-Way System Setup and Operation; Signal Mixing and System Expansion

Setup Diagrams for 5xA Two-Way Systems (cont)
* If you are using the SxA two-way system with a rnicrophone 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, simjdy 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 he. I’Vpically, a mixer mute switch may be engaged or a,
microphone that is switched off is the source of the problem. Keeping the syste.m 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 lilQ controls set in the flat position (12 o’clock, middle positi.on) 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 SxA systems, simply hook an Xi-ih-type cable from the line
output connector on the source system to the line input connector on each additional SxA
system. The signal can be cascaded into a large number of SxA systems without
degradation.
* When turni.ng your system off, turn off the SxA systems first. This will prevent any turn¬
off transients from other pieces of equipment from being amplified.
