Step 1 Connecting the transmitter
The transmitter provides 2 digital interfaces and 1 analog interface to connect
to an audio source.
The transmitter accepts a digital audio signal at both the electrical and optical
digital interface. By using one of the digital interfaces, audio data can be fed
directly into the transmitter. This bypasses the digital-to-analog and analog-to-
digital conversion and thereby eliminates audio distortion.
Many HiFi components provide a digital audio interface. The format of the
digital audio which is fed into the transmitter must be uncompressed S/PDIF
stereo data at a sampling rate of 32 kHz, 44.1 kHz or 48 kHz. Compressed
multichannel audio data (which is provided by many DVD players) cannot be
processed by the transmitter. In such case, set the format of the DVD player
audio interface to uncompressed stereo data.
Connect the digital audio output of the audio source with the digital audio
interface of the transmitter by using an RCA cable if the electrical interface is
used. If the optical interface is used, connect the transmitter by using an
optical audio cable (not included).
Connect the DC power input with the supplied AC adapter. The use of a surge
protector is recommended to protect the transmitter from power surges and
audio dropouts.
Digital Audio Interface
Analog Audio Interface
DC Power Input
Analog audio can be fed into the transmitter via the analog audio interface.
Analog audio is converted to digital audio inside the transmitter by an analog-
to-digital converter.
The analog audio interface can be connected to a line out interface which is
provided by most audio sources. The analog audio interface can also be
connected to other analog outputs by using an appropriate adapter.
The transmitter will accept maximum audio levels between 0.2 Vrms and
10 Vrms. Prior to operating the transmitter, the analog audio interface should
be set to the correct audio level by adjusting the analog audio interface level
control (see page 7).
