Introduction
Thank you for choosing this Harman Kardon product!
For more than fifty years, the Harman Kardon mission has been to share a passion for music
and entertainment, using leading-edge technology to achieve premium performance.
Sidney Harman and Bernard Kardon invented the receiver, a single component designed
to simplify home entertainment without compromising performance. Over the years,
Harman Kardon products have become easier to use, while offering more features and
sounding better than ever.
The AVR 3700/AVR 370 7.2-channel and AVR 2700/AVR 270 7.1-channel digital audio/
video receivers continue this tradition with some of the most advanced audio and video
processing capabilities yet, and a wealth of listening and viewing options.
To obtain the maximum enjoyment from your new receiver, please read this manual and
refer back to it as you become more familiar with its features and their operation.

IMPORTANT SAFETY INFORMATION
Verify Line Voltage Before Use
The AVR 3700 and AVR 2700 have been designed for use with 120-volt AC current.
The AVR 370 and AVR 270 have been designed for use with 220 – 240-volt AC current.
Connection to a line voltage other than that for which your receiver is intended can create
a safety and fire hazard and may damage the unit. If you have any questions about the
voltage requirements for your specific model, or about the line voltage in your area,
contact your selling dealer before plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power cord supplied with your unit. We do not
recommend that extension cords be used with this product. As with all electrical devices,
do not run power cords under rugs or carpets, or place heavy objects on them. Damaged
power cords should be replaced immediately by an authorized service center with a cord
meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC outlet, always pull the plug; never pull
the cord. If you do not intend to use your receiver for any considerable length of time,
disconnect the plug from the AC outlet.
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, wire or staple accidentally falls inside
the unit, disconnect it from the AC power source immediately, and consult an authorized
service center.
CATV or Antenna Grounding (AVR3700/AVR 2700)
If an outside antenna or cable system is connected to this product, be certain that it is
grounded so as to provide some protection against voltage surges and static charges.
Section 810 of the United States National Electrical Code, ANSI/NFPA No. 70-1984,
provides information with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna discharge unit, connection to grounding electrodes and
requirements of the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV (cable TV)
system installer’s attention to article 820-40 of the NEC, 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 possible.
Place the Receiver
sPlace the receiver on a firm and level surface. Be certain that the surface and any
mounting hardware can support the AVR’s weight.
sProvide proper space above and below the AVR for ventilation. Recommended
clearance distances are 30cm above the unit, 30cm behind the unit and 30cm on
each side of the unit.
sIf you install the AVR in a cabinet or other enclosed area, provide cooling air within
the cabinet. Under some circumstances, a fan may be required.
sDo not obstruct the ventilation slots on the top of the receiver or place objects
directly over them.
sDo not place the receiver directly on a carpeted surface.
sDo not place the receiver in moist or humid locations, in extremely hot or cold
locations, in areas near heaters or heat registers, or in direct sunlight.
