Putting the RS 175 into operation Putting the RS 175 into operation Setting up the transmitter 왘 Choose a suitable place near your audio source. 왘 Separate the transmitter and other wireless devices in a room by at least 50 cm/20” to avoid interference. 왘 Do not place the transmitter close to metal objects such as shelf bars, reinforced concrete walls, etc. as this can decrease the cover range of the transmitter.
Putting the RS 175 into operation Connecting the transmitter to an audio source You can simultaneously connect 2 different audio sources (e.g. a TV and a stereo hi-fi system) to the transmitter. The transmitter features a digital as well as an analog audio input. If you connect 2 audio sources, you can toggle between them using the AUDIO INPUT SELECTION switch (see page 22). You can also refer to the beginner’s video guides on how to connect your digital wireless headphone system to a TV at www.sennheiser.
