IFU AD905W
Author: JDR/EDN
Date: 30/11/2002
Instruction For Use (IFU) for Wireless Audio set AD905W
a) Unpack all parts: transmitter, receiver/amplifier, 14V adapter, table stand
b) Connect the rear speakers terminals to the appropriate connector sockets of the
receiver/amplifier.
c) Place the receiver/amplifier unit at a minimum of 30cm above ground to avoid bad
wave propagation; use the table stand as shown in the picture
d) Connect receiver/amplifier to mains by use of power cord.
e) Green led receiver/amplifier should light
f) If led is not lighting, shift small power switch next to the connectors to the ON
position. Green led should light now.
g) Place the transmitter unit at a minimum of 30cm above ground to avoid bad wave
propagation. Make sure transmitter and receiver are not closer than 2m from each
other.
h) Connect the 14V power adapter to the transmitter
i) Connect transmitter-inputs to DVD surround – output. Be sure to connect right input
to right output connector of DVD, idem for left channel? Mach the Blue and Grey
colour.
j) Power up the transmitter. Red led of transmitter unit should light now.
k) Make sure that transmitter and Receiver/amplifier are using same audio
transmitting/receiving channel. Please select same channel by use of the 4-position
switch on both units.
l) Start the audio source, be sure that surround - mode is enabled. Set volume to position
5; surround sound should be audible in the rear speakers.
m) Rotate antenna of both receiver/amplifier and transmitter into vertical position for
good reception
n) Red led on transmitter is on for at least 4 minutes. After switching off the DVD player,
the transmitter goes automatically to standby mode after 4 minutes= red led off; when
there is an incoming audio-signal from the DVD, the transmitter starts automatically.
The transmitter is also enabled at power – up for at least 4 minutes.
o) Receiver-amplifier combination is always on for at least 10 minutes = green led on.
When the transmitter stops (red led off), the receiver-amplifier will mute, green led
stays on, and after ten minutes the amplifier-receiver goes into s leep-mode = red led
on
p) When distorted audio is noticed, please select different channel as the interference
could be caused by other equipment in your house using same freq. channel or even by
one of your neighbours.
q) The metal table stand can be used for slightly upright position of the receiver/amplifier
unit. If used, make sure you rotate the antenna towards vertical position.
NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV
INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO
OPERATE THE EQUIPMENT.
1. GENERAL
The Mark-3 transmitter is designed specifically for use with a TV set as a surround signal (Digital
Dolby or ProLogic) transmitter towards wireless surround speakers.
As such the transmitter can be connected via a cable assy. towards the TV set. Audio, supply and
I²C signals can be extracted out of the TV chassis. The transmitter is designed for high quality
stereo audio from 20Hz to 20kHz and has a compander to enable high S/N ratios.
The basic version is intended for the European freq. band of 863-865 MHz. Derived versons are
available for 433 and 914 MHz.
The pilot and subcarrier frequency have been set to 23.4375 kHz and 46.875 kHz. (3th harmonic
related to 15.625 kHz). This way interference whistling in TV sets with 15625 Hz is avoided.
Further the translitter has improved pulling behaviour which results in additional immunity to
picking up stray EM-fields from the TV hardware.
The Mark-3 module needs proper I²C signals from the host controller at hex C6 to properly set the
synthesiser and other functions on board of the Tx. For details on I2C commands to send refer to our
document " I2C commands for Mark-3 Transmitter" archived under 3104 217 07110 sheet 112.
2. USED TECHNOLOGIES AND DIMENSIONS
The design platform is MentorGraphics with CE design rules acc. UAND1829 & UAND1833.

4. FEATURING
The following main features are installed :
-no spurious RF power output when applying DC power to the Mark-3 module.
-pilot mute possibility to mute the speaker remotely
-pilot mute at power-down (TV set switch off or mains cord pull)
-on board printed aerial that supports 864 and 926 MHz . There is a backup solution with a
telescopic aerial (17cm) for 433 MHz versions. (all vertical polarisation)
-build in audio limiter to limit the emitted RF bandwidth to the ETSI requirements .
- 4 RF channels avilable on a 400 kHz grid (all versions)
-the local osc. and power amplifier can be switched off by I²C commands.
-a mono-stereo switch to switch out the DSB spectrum around the subcarrier freq.
-improved load-pull behaviour
Note :
-the host microcontroller needs to send detailed I²C commands to the module because there is no
local uP on board for cost saving reasons. For full details on I²C codes to send refer to the Software
interface manual sheet 112 of 3104 217 07110.
-there is no audio trigger circuit foreseen in the basic module for BGTV application because the
competent body considers the 5min timeout period in the ETSI EN 301 357-1 requirements to be
fulfilled when the TV is switched to standby or to off.
5. ENVIRONMENTAL AND EMC
The design meets the technical and legal requirements for the different frequency band executions :
-EN 301 357 :
Technical requirements for wireless audio at 25 MHz – 2GHz.
-EN 301 489-9 :
EMC for cordless audio and radiomicrophones
-FCC
part 15 , subpart C (US 926 MHz version)
-Safety requirements : acc. CE and BGTV requirements.
6. USED KEY COMPONENTS
-compander function :
-pilot / subcarrier generator
-MPX filter :
-synthesiser
