IMPORTANT SAFETY INSTRUCTIONS
14. LIGHTNING: For added protection for the unit during a lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent
damage to the unit due to lightning and power line surges.
15. POWER LINES: An outside antenna system should not be located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside
antenna system, take extreme care to keep from touching such power lines or circuits as contact with them might be
fatal.
16. OVERLOADING: Do not overload wall outlets, extension cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.
17. OBJECT AND LIQUID ENTRY: Never push objects of any kind into the unit through openings as they may touch
dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind
on the unit.

your system.
AC Fuse: The fuse is located inside the chassis and is not user serviceable. If power does not
come on, contact your authorized service representative.
Wiring: Cables that run inside of walls should have the appropriate markings to indicate compliance with, and listing
by the UL, CSA or other standards required by the UL, CSA, NEC or your local building code. Questions about cables
inside of walls should be referred to a qualified custom installer, or a licensed electrician or low-voltage contractor.
Do Not Open the Cabinet: There are no user serviceable components inside this product. Opening the cabinet
may present a shock hazard, and any modification to the product will void your warranty. If water or any metal
object, such as a paper clip, coin, or staple accidentally falls inside the unit, disconnect it from the AC power source
immediately and contact Cary Audio for further instructions.
24. RECORDING COPYRIGHT: Recording of copyrighted material for other than personal use is illegal without
permission of the copyright holder.
25. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention to
article 820-40 of the NEC, ANSI/NFPA 70, which provides guidelines for proper grounding and, in particular, specifies
that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry
as practical.

NORMAL OPERATION:
The majority of time you spend with your C 306 will be spent in normal operation.
During normal operation, the display indicates the name of the input you have
selected and listening volume. The VOLUME knob increases or decreases the
volume in 0.1dB increments above 50 ( and in 1.0 dB steps below this low level).
The SELECT knob selects the source to be listened to at any point in time. In short,
in normal operation, the C306 acts precisely as you would expect a preamplifier to
act.

THE BALANCE:
The BALANCE give you extremely fine control over the relative volume of the left
and right channels, by changing the volume of one relative to the other in increments
of 0.1 dB, up to 10 dB.
THE FUNCTION OF POLARITY:
The C 306 allows you to invert the polarity of the music to which you are listening
with the press of a button. People vary in their sensitivity to this aspect of the sound,
and the difference frequently ranges from subtle to inaudible, depending on
microphone technique and other factors in the recording itself. However, some
recordings simply sound correct in one position, and wrong to the other.
We encourage you to experiment with the polarity feature to see what you think works
best for any given recording, understanding that the recordings themselves are not
consistent.
4
THE DC TRIGGER:
The C 306 allows you to use the DC TRIGGER output on the rear panel of the C 306
Controller to turn on some other component automatically when the C 306 itself is on.
You have three trigger outputs, either a 12V level voltage that is present whenever
the C 306 is operational, or absent when the C 306 is in standby.
If you are not sure what the receiving component needs for a trigger signal,
please ask your Cary Audio dealer for assistance.
