User and Installation Guide

Unpacking: Check that this package contains:

One set of 5.8 GHz Digital Wireless Headphones, one 5.8 GHz Digital Audio

transmitter, one AC adapter, one dual RCA audio cable, four NiMh batteries.

Step 1

Connecting the transmitter

The transmitter provides 2 digital interfaces and 1 analog interface to connect

to an audio source.

Digital Audio Interface

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).

Analog Audio Interface

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).

DC Power Input

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.
