The second zone feature requires either an external amplifier to power the speakers in this zone, or if your Rotel receiver offers an amplifier redirect feature, the redirected amplifiers can be used instead. 

The second zone can only be used with analogue signal sources. 

There are several different ways to control the remote zone on your Rotel product – from the front panel of the unit, via the remote control, using an external IR remote system, or using an RS-232 based control system.

Your authorised dealer would be the best contact for detailed information on this topic to help determine which method would work best for your application. 

The zone can be controlled from the front panel of most Rotel products by pressing the ZONE button followed by adjusting the volume or input source.
