Hope this helps. Thanks first for the pictures. Newer AVR's like this one put out a good bit of heat. Just like a car in a Texas summer you need air circulation to keep it cool. From your pictures it shows your unit against the bookcase wall on the right side which minimizes air circulation. Also I can see the front feet of the unit hanging off the front of the shelf. This puts the bottom of the unit literally on the shelf at that point which greatly reduces the space under the unit for airflow. This blocks air from circulating underneath the unit. The heat is not disipated but rather trapped in the corner of the bookcase. Try putting your AVR on a flat surface with all four feet on a shelf with plenty of air circulation. You may even want to put a fan nearby. Also make sure nothing is ever on top of the unit. My AVR has air circulation on all four sides and srill gets pretty warm on the top. If all of this fails try contacting Marantz or the store where you bought it. Good Luck!
Sorry, there was a problem. Please try again later.From the picture. I see the bottom is not being vented (on the caster). The smell could be of burnt dust with the top being so open. I've had mine a few months and I have noticed it runs warm and was concerned I didn't have enough open space for the top. But all seems well.
Sorry, there was a problem. Please try again later.Please make sure you're giving the unit at least 6 inches of clearance above the top vents so the heat can dissipate properly. If that's not possible, then you may need an AV cooling unit to help keep internal temps down.
