Does the ZA3100ES have Bluetooth or wireless capability?
A shopper on Jun 15, 2018
  This receiver has a wired Ethernet connection but does not support WiFi or Bluetooth.
What is the temperature requirement and air circulation requirement for the 3100 and 5000 units?
A shopper on Mar 16, 2021
  Thanks for your inquiry. There is no specification regarding safe temperature or air circulation. Like all large chassis 7 (or more) channel AV receivers, convection cooling should not be restricted on top (2 to 3) at sides and below. Air should be able to enter from front under the chassis and out the top of the unit and out the back. With all channels playing at a room filling volume you should be able to put your hand on top and not find it hot. Warm is normal but high heat is bad for the life of the unit. There are a number of cooling solutions available depending upon your situation.
