CHAPTER 3 | INSTALLATION AND OPERATION
CONNECTING THE 115VAC POWER CORD
The included AC power cord must be inserted into the AC input receptacle on
the AD-4x. When the AC power cord is connected to a power source, press the
Power button to turn the AD-4x on and off.
IMPORTANT NOTICE FOR INTERNATIONAL DEALERS/DISTRIBUTORS
This product is shipped from RTI with AC voltage set to 115 Volts. The voltage
will have to be changed for certain international locations. Ensure that the red
115/230 AC Voltage Switch on the underside of the unit is properly set for your
location.
*The red voltage switch should be left in the 115 Volt position if
used within the United States.
CONNECTING LOCAL AUDIO SOURCES
The AD-4x has four sets of RCA audio inputs for connecting up to four external
source components. These four audio sources can be selected to play in up to
four zones. Also, if users in more than one zone choose the same audio source,
control of that source is shared between the zones.
•
Trim Control
: The Trim Control dials on the AD-4x are used to equalize
signal levels of each input source to ensure that switching between inputs will
result in the same output level. The Trim Control is initially set at zero (no
attenuation).

FREE STANDING
The AD-4x ships with four removable feet that allow it to be placed on a flat
surface. To maintain proper ventilation and cooling, do not install the AD-4x on
a flat surface without the feet.
RACK MOUNT
The AD-4x can be mounted in a component rack as part of a comprehensive
audio/video electronics system using the included rack mounting ears. Align
the rack mounting ears with the screw holes located on the sides of the AD-4x
near the front. Fasten the rack ears to the AD-4x using three screws (supplied).
Remove feet before mounting in a rack.
NOTE: To maintain proper ventilation, it is recommended that you leave a rack
space above and beneath the AD-4x if possible.
