Introduction, Supplied Accessories,  

Important Safety Information and Place the Receiver

3

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 2700, Avr 370 and 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.
If you have any questions about this product, its installation or its operation, please 

contact your harman kardon retailer or custom installer, or visit the web site at  

www.harmankardon.com.

the following accessory items are supplied with your receiver. If any of these items are 

missing, please contact your harman kardon dealer or harman kardon customer service 

at www.harmankardon.com.

•  System remote control
•  Zone 2 remote control (Avr 3700/Avr 370 only)
•  ezSet/eq™ microphone
•  Am loop antenna
•  fm wire antenna
•  Six AAA batteries (Avr 3700/Avr 370); four AAA batteries (Avr 2700/Avr 270)
•  Ac power cord

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 on a firm and level surface. be certain that the surface and any 

mounting hardware can support the Avr’s weight.

•  provide 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.

•  If 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.

•  do not obstruct the ventilation slots on the top of the receiver or place objects 

directly over them.

•  do not place the receiver directly on a carpeted surface.
•  do 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.
