Step 4: Completing the Electrical Connections

Trim the SJO cord to a neat length while allowing enough slack for future
aiming adjustments or service. Make electrical connections per all ap-
plicable codes in a weather-tight box and secure the SJO cord through a
weather-tight gland nut. Observe color code for proper polarity: Black wire
from speaker is audio (-), white wire is audio (+).
Using the PIX (Constant Voltage Version)
Constant Voltage Design Considerations
One of the major expenses of any large sound system up-grade is the cost
of running new wiring. For this reason, the Sx600PIX transformer has taps
for use on lines as high as 200volts, which is easily delivered by an Electro-
Voice CPS-4 amplifier in bridge mode. Keeping the current draw the same,
changing from 70volts to 200volts means you can now pull approximately
3 times the wattage from the same wiring! In new installations, the higher
voltages mean less line loss on long runs, less current and lighter gauge
wire. Always check and comply with all applicable codes.
