Companion's temperature in Dual Mono
The companion unit remains warmer than the master, even in standby mode. Indeed, the companion keeps a minimal activity while it is awaiting instructions from the master unit. This is because only the master unit receives information from the remote.Furthermore, if your two devices are superposed, then while playing it is also normal that the lower unit becomes warmer than the upper one as it is less easy for the lower unit to dissipate heat than for the upper unit.This is perfectly right and you do not have to worry.In addition, the new version of the firmware 7.1, we did increase the energy availability. As a result, the temperature is higher. The temperature will as well depend on the efficiency of the speakers, the type of music you are listening to, and the power you are listening to it.
