FIXING OF OPTIONAL SPEAKER STANDS
If your DS1033 system has speaker stands please follow these instructions.

1. First make sure that all connections are correctly made:
• Connect the power plug to a suitable mains socket and switch the
DS 1033 system ON using the power switch (9). After about ten
seconds the LCD display will illuminate and the unit will operate.
2. Select the desired input:
• Select AUX (1) on the remote control unit to listen to the analogue
stereo sound source connected to the AUX inputs on the rear
panel (5).
• Select COAXIAL (3) on the remote control unit to listen to the digital
audio source connected to the COAXIAL input connector on the rear
panel (6).
• Select OPTICAL (2) on the remote control unit to listen to the digital
audio source connected to the OPTICAL input connector on the rear
panel (7).
3. Listening mode selecting:
• Depending on the type of input selected, pressing the EFFECT
buttons (3) allows you to select one of the Dolby Digital listening
modes “THEAT” (theatre), “MATRX” (Matrix), “LIVE”, “CHUR”
(Church), “ STADU” (Stadium), “SIMUL” (Simulated), “HALL” or
“CHORU” (Chorus), according to personal preference.
• According to the type of digital input, pressing LISTEN MODE (12)
allows you to select the Dolby Digital decoding options of PRO
LOGIC, STEREO or PHANTOM (Simulated surround sound from stereo
input). The DS 1033 automatically detects the type of signal being
input from a DVD player, and highlights “Dolby Digital” if a 5.1 Dolby
Digital signal is input, “PRO LOGIC” if the input signal is Pro Logic,
or “Stereo” if a stereo signal is being input. The LCD display shows
which channels are working - for example 2/0 indicates the front left
and right speakers only are working, 3/2 indicates the front left and
right, centre and surround speakers are working.
NOTE: Many DVD discs support multi-soundtrack options, so the
digital signal input to the DS 1033 will be determined by the DVD
player settings. The DS 1033 stores the last settings when
switched off, and will restore these settings when next switched on.
SYSTEM FUNCTION AND OPERATION
4. Adjusting the delay time of the Centre and Surround channels:
• Depending on the type of digital input being decoded, it is possible
to change the delay time of the signals heard in the centre (dialogue)
channel and the rear (surround) speakers. Pressing CS DELAY (8)
allows you to select the centre or surround channels, and using the
+ and - buttons (9) allows you to set the delay time of each channel
(centre channel delay time from 0 to 5 ms (milli-seconds), and the
surround channel from 15 to 30 mS.)
NOTE: The delay time setting is also dependent on the type of
soundtrack being input, and decoding option setting.
5. Adjusting the volume levels:
• The volume of the Centre, Surround (rear) and Sub Woofer channels
can be individually set according to personal preference and room
conditions.
• Selecting TEST (10) outputs a white noise signal to facilitate setting
the volume levels the Centre, Surround and Sub Woofer channels.
• Using C S TRIM (6) to select each channel, the +/- buttons (7) allow
you to set the sound level of each channel.
6. Tone adjustment:
• The system tone can be adjusted using the BASS +/- buttons (13)
and TREBLE +/- buttons (14) in the range of +/- 10 dB.
7. Standby:
• If the DS 1033 is not going to be used for a while, selecting
STANDBY (13) switches the system into standby (power save) mode,
indicated by the STANDBY LED (1) on the front panel. Reselecting
STANDBY (13) restores the system to normal operation, with all
previous settings.
NOTE: If the DS 1033 is not going to be used for a period of time, it is
recommended to switch OFF the system with the power switch.
8. Mute:
• To temporarily mute the sound output of the DS 1033, select MUTE
(11). The MUTE LED (4) on the front panel indicates the system is
muted. To restore the system to normal operation, reselect MUTE
(11).

TROUBLESHOOTING
System does not switch on:
• Check mains lead securely tted to a working mains outlet socket.
No sound from one or more channels:
• There is a 10 second delay after switching on before system starts
functioning.
• Check all speakers connections are correct and all leads are
secured.
• Check all input leads are correctly wired and all connectors are
securely tted.
• Check the settings of the input device (DVD player, etc.)
• Check channel volume settings.
• Check that the MUTE function is not selected.
Volume level low:
• Check master volume setting (maximum setting value 60).
• Check individual channel volume settings (maximum value +
10 dB).
Sound distortion:
• Check all inputs are correctly wired up.
• Check input device settings.
• Check that the volume level is not set too high.
Remote control not operating correctly:
• Check the batteries, if the remote controller only works when close
to the DS1033, the batteries are getting low - replace with suitable
AAA sized batteries.
• Do not use rechargeable batteries.
• Check there is nothing obscuring the remote signal sensor on
the front panel.
• Check the sub woofer unit is not in direct sunlight, as this can
reduce the effectiveness of the remote controller.
