Subject: Independent Second Zone Feature
As an example, while your family is enjoying a movie in the main Home Theater room, you can relax to your favorite CD in the den. On another occasion, you might be watching a ball game on the big screen in Stadium Surround Sound in the main Home Theater room while someone else is listening to their favorite radio program in another room. Many installation applications are possible with the independent second zone feature.
An infrared repeater system is necessary to take advantage of the second zone feature. Your Rotel dealer can provide an infrared repeater system and help you design your second zone installation. The following information is common to all Rotel second zone operation unless noted otherwise:
1) The back panel of your Rotel component includes RCA connections that provide a variable line level stereo output to the second zone. Any audio source connected to your Rotel component is available to the second zone output. A Rotel power amplifier connected to the second zone output is required to power the speakers in the remote location.
2) A third party infrared repeater system can be connected to the 3.5 mm jack labeled
REMOTE IN
control handset is used to command the second zone operation through the infrared repeater system. The infrared repeater system usually includes:

3) Also available on the back panel of your Rotel component are one or more 3.5 mm jacks labeled REMOTE OUT. An LED flasher can be connected from the REMOTE OUT jack to the source component to provide (see 8 below) back panel to eliminate an LED flasher on the front panel.
4) The REMOTE IN 3.5 mm jack is not active until the component is powered up from standby (except RTC 970). Your Rotel component must be turned on before commands will be accepted at the REMOTE IN 3.5 mm jack. It is possible to power up the RA 985BX or RTC 970 from the second zone by pressing the power command button on the remote control. The IR repeater system must be connected to the RA 985BX or RTC 970 front panel IR sensor with an LED flasher. not activate the REC / ZONE command before the power command.
5) Some infrared repeater systems rely on radio frequency transmission to send the remote command from the second zone sensor back to your Rotel component. This type of system has certain advantages and disadvantages compared to a hard wire type system. Basic operation of both system types is the same. Your Rotel dealer can help determine which type of infrared repeater system is best for your installation.
6) It is important that the second zone remote infrared sensor is located so that a command from the remote control handset does not affect both the remote sensor and your Rotel component at the same time. There is no harm to the system if this situation occurs however, operation can be adversely affected.
7) The remote control handset that is included with your Rotel component will operate both your Rotel component and the second zone. Second zone operation includes:
8) The RR 927 and RR 970 remote control handsets will control your Rotel source components from the second zone. command before the control handsets are available from your Rotel dealer.
