System Setup
To get your

system into operation as quickly as possible, please observe the following steps
and precautions (see Figures 3-7)
·
Plug the 3-terminal IEC 16-gauge ac cable into a grounded line receptacle. Extension cords
can be used to lengthen the ac cable as necessary but make sure that they are 3-conductor
14 gauge or greater, and that are properly grounded to avoid electrical hazards and
extraneous noise.
·
Be sure that the
S
x
A
system is plugged into an ac power source that is capable of supplying
the correct voltage. If the line voltage drops too much, the built-in amplifiers won’t be able to
develop
their rated power and sound quality will suffer. Under high signal conditions,
the S
x
A amplifier section can pull 2 – 4 amps of current (120 volt models) (1 – 2 amps at
240 volts). That means that no more than 4-S
x
A systems should be plugged into a single 15
amp electrical service. Be cautious of what else is plugged into the same electrical service
line to avoid electrical problems and poor performance.
·
BEFORE TURNING THE POWER ON, MAKE SURE THAT THE LEVEL CONTROLS
ARE DOWN TO AVOID TRANSIENTS OR UNEXPECTED LOUD SOUND. Turn on the
power switch and ensure that the system is receiving power by monitoring the status LED
to the left of the switch above the EQ controls. If the system is receiving power, the LED
will illuminate green.

A loudspeakers have narrower coverage than other compact loudspeaker systems. Their
narrower coverage will help you avoid room acoustics problems by delivering the sound
where the speaker is aimed. You will find that precisely aiming the speakers at the
audience area away from walls will give you better sound quality.
