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.

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 70, AVr 700 and AVr 70c 5.1-channel digital audio/video receivers (AVrs) 

continue this tradition with some of the most advanced audio and video processing 

capabilities yet and a wealth of listening and viewing options.

the AVr 700 has been designed for use with 120-volt alternating current (Ac). the  

AVr 70 and AVr 70c have been designed for use with 220 – 240-volt Ac. connection 

to a line voltage other than that for which your AVr 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.

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.

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 AVr for any considerable length of time, 

disconnect the plug from the Ac outlet.

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  AVR  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, 10cm behind the unit and 20cm 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 AVR or place objects directly 

over them.

•  Do not place the AVR directly on a carpeted surface.
•  Do not place the AVR in moist or humid locations, in extremely hot or cold locations, 

in areas near heaters or heat registers, or in direct sunlight.
