Recording from your SONUS-1XT
You can record from your SONUS-1XT using the Stereo Out or Digital Out sockets.
You can also set a record timer to automatically switch your unit on and tune to
a particular station at a time of your choosing – this may be useful if you have
a MiniDisc recorder or similar with a synchro-record facility and you use the
Digital Out socket. You cannot record one station and listen to another at the
same time. Note The volume level of the recording is at a set level and is not
dependant on the position of the volume knob.

These instructions will not set the record time on your recorder. Some recorders
can detect when a digital S/PDIF signal is present (synchro-record) or you may
have to set your external recorder to start recording at the same time.
If using a synchro-record method you should check that the Digital out socket
is set to Off/Timer so that your recorder can detect when the recording is to
start. To do this, Push the Menu button, select Audio settings and choose Digital
output. Select the Off /Timer option.
When finished, press the Menu button or wait a moment and you’ll return to the
idle display mode and the timer will be set. If your display mode is set to Clock
you will see a timer symbol on the screen showing that one or more timers are
set. The timer list will also show ‘Set’ next to those that are currently active.

stations are displayed with a heart (♥) next to their names.
Active station Displays active stations at the top of the service list and inactive
ones at the bottom in alphanumeric order. Inactive stations are
those on your station list but not currently available, marked with
a ’?’.

The Digital Output setting controls the Digital Out socket on the rear of your
radio. Turn the Tune knob and push to select one of the following options:
On - if you want continuous output to an amplifier or recorder.
Off/Timer - if you want to connect to a recorder with a synchro-record feature.
DRC value
DRC (Dynamic Range Control) value makes the quieter sounds in a broadcast
easier to hear at low volume or in a noisy environment. The DRC level of a
broadcast is set by the station and sent with the signal. At the time of writing in
the UK only BBC Radio 3 and 4 regularly use DRC. Check with the broadcasters
to find out if they use DRC on their stations.
The DRC value setting is only available if VET is set Off see the following section
for details. Turn the Tune knob to scroll through the following options and push
to select one:
DRC 0 DRC is switched off. Any DRC level broadcast will be ignored.
DRC ½ DRC level is set to ½ that sent with the broadcast.
DRC 1 Applies the DRC level as sent with the broadcast.
VET levelling
VET levelling
VET (Volume Equalisation Technology) helps level volume levels across
different stations making each sound as if it is at the same volume. It does this
by constantly monitoring the stations on your station list and lowering or raising
their volume to meet an optimum level.
Note When VET is On use of DRC would distort the levelling effect so DRC is
disabled when VET is On.
Turn the Tune knob and push to set VET On or Off.
Tuning SONUS-1XT is very simple. When you first switch on it automatically finds
all the stations available in your area. You may want to re-tune if you move your
radio to a different room or if you want to receive a new multiplex. Multiplexes,
sometimes called ensembles, are groups of stations owned and broadcast by a
single operator. You can re-tune your SONUS-1XT at any time using the following
three tuning options:
Autotune UK
Scans all UK frequencies. This should only take a few seconds.
Autotune full
Scans the full frequency range in Band III. This is useful if you use your
SONUS-1XT outside the UK and may take a minute or more.
Manual tune
Shows signal level, which you can use to find the best position for your radio
and aerial.
1. Turn the Tune knob to scroll through different channels and push to choose
one (UK stations are in channels 11B to 12D). You see a signal level
display.The empty block indicates the minimum required level for reception
and the filled blocks indicate the current level.
2. Move your aerial while watching the display and to try to raise the current
level to the empty block or beyond. Once you have a good signal the display
will show the multiplex name and add the stations in that multiplex to the
station list.
3. Push the Menu button to exit or turn the Tune knob and push to change
Note You can also display the signal level for a station by pushing the Tune knob.
Sw version
Displays the version number of the software installed in your radio. You may be
asked to quote this if you contact Technical Support.
Sw upgrade
You can upgrade the software in your SONUS-1XT using a PC connected to the
USB connection on the rear panel. To install an upgrade, select Sw upgrade
and follow the instructions provided with the software. Upgrades may be issued
to provide enhanced functions or improve performance. Check our website for
details of when software upgrades are available and instructions on how to
install them. To exit the Software upgrade menu press the Menu button again.
Demo mode
This mode demonstrates the unique speech features of the SONUS-1XT including
accessing alarm times and station name announcement. Info modes are also
demonstrated. While the unit is in demo mode a DEMO icon will appear on
display. All controls will work as normal when demo mode is switched on.
Note Demo mode works even if you currently have no signal. SONUS-1XT will use
pre-recorded samples for time and other announcements in this situation.
Turn the Tune knob and push to set the demo mode On or Off.
Hints and tips
This section provides information and advice on using your radio.
(‹‹/››) Secondary services
Secondary services accompany some stations, providing extra information or alternative content
and may only be broadcast at certain times. At the time of writing not many secondary services are
available. If a station has one or more secondary services available the display will show ‘>>’ next to
the station name on the station list and the secondary service will appear next to the station as you
turn the Tune knob. A secondary service will display ‘<<’ before the service name on the station list
showing that it belongs to the station preceding it in the list.
(?) Inactive or unavailable stations
Inactive or unavailable stations are stations which appear on the station list but are not currently
available because either you are outside the broadcast area, have lost reception or the station is
not currently broadcasting. If the station has ‘?’ before its name in the station list the station is
unavailable. If you select a station which has this symbol, your radio tries to tune to that station. If still
unavailable, you will return to the last station you were listening to.
I hear a ‘burbling’ sound on some stations
Although DAB is excellent at providing quality audio from very little signal, the quality can suffer if the
signal strength is too low. If that happens, a ‘burbling’ sound can sometimes be heard. To help reduce
this, check that your aerial is fully extended and upright. If the problem persists try moving your radio
or repositioning your aerial using manual tuning.
Display says ‘No stations available’
Check that your aerial is fully extended. Use Autotune to search for stations. Try using manual tuning to
adjust your aerial or radio position.
My alarm/timer didn’t work
Check that you set the alarm or timer on (If display mode is set to clock you will see a timer or alarm
icon on the display).
Check that the station you are tuned to is available – the clock/alarm/timer relies on the time signal
broadcast by the multiplexes.
If you are using synchro-record check that you have set the Digital out to Off/Timer this triggers your
Clock shows the wrong time
This may happen if the multiplex you are tuned to broadcasts an incorrect time signal, try tuning to a
station in another multiplex.
None of the buttons seem to work
If the display is on but most buttons seem not to work your SONUS-1XT may be in standby. If so, you
should see a standby indicator ( ) on screen.
I can’t see my clock in the dark
Tap or hold (full brightness) the SnoozeHandle to illuminate the display if your unit is in standby or set
your display backlight on for permanent illumination.
Resetting your radio
Resetting your radio removes all presets, stored stations and favourite station settings and resets all
options to defaults. To select the reset option:
1. Press and hold the Menu button for more than two seconds. The display will show ‘Press Tune to
confirm reset’. Release the Menu button.
2. Press the Tune knob to confirm the reset or press no buttons to cancel the reset.
