Fan Vents: This area contains vents used by the AVR 7550HD’s fan to cool the system. Maintain a clearance of at least 3 inches from the nearest surface to avoid overheating the unit. It is normal for the fan to remain off at most normal volume levels. An automatic temperature sensor turns the fan on only when it is needed.
IMPORTANT NOTE: Never block the fan vents, as doing so could allow the AVR to overheat to dangerous levels.
Zone 2 Video Output: Connect this composite video jack to a video display located in the remote zone of a multizone system. When the multizone system is in use, viewers in the remote zone will be able to see the AVR’s

Switched AC Accessory Outlet: You may plug the AC power cord of one source device into this outlet, and it will turn on whenever you turn on the receiver. Do not use a source that consumes more than 50 watts of power.
AC Power Input: After you have made all other connections, plug the AC power cord into this receptacle and into an unswitched wall outlet.
