Introduction
Infrared (IR) remote controls do not work properly when obstacles between the
remote control and the audio/video devices disturb the operating signal. This
problem can be solved using radio frequency (RF) as a carrier for IR commands.
The Marantz touch screen remote controls (see note below), in combination with
the RF Extender, can operate audio/video devices from virtually any location.
The RF Extender consists of two units: a Receiver unit, and a Blaster unit.
The Receiver unit receives RF signals sent out by the Marantz touch screen remote
controls. This unit is connected to the Blaster unit, which converts the signals into
IR signals. The Blaster unit then transmits the IR signals to the audio/video devices.
Note
Marantz
When the Blaster unit cannot reach all devices or transmits with too much power,
you can use the included Dual IR emitters. You can set up the Dual IR emitters in
two ways:
I
The Dual IR emitters in combination with the Blaster unit.
When there is limited space around the IR receivers of the devices, for
instance in a small closet.
I
The Dual IR emitters instead of the Blaster unit.
When you want to transmit IR signals very accurately, you turn off the Blaster
unit, and control the devices by using the Dual IR emitters alone.
