Standby/On
1
Switches the unit between Standby mode (indicated by dim power LED) and
On (indicated by bright power LED). Standby is a low power mode where the
power consumption is less than 0.5 Watts. The unit can be left in Standby
mode when not in use.
Headphones socket
2
Allows for the connection of stereo headphones with a ¼ inch jack plug.
Headphones with an impedance of between 32 and 600 ohms are
recommended.
Note: Plugging in headphones will automatically mute the loudspeaker
outputs.
Skip/Scan buttons
3
The skip scan buttons are used when the FM/AM tuner is selected. These
buttons have different uses depending on the mode selected:
In Preset mode - Steps up or down through the user-stored presets.
In Auto mode - Searches for the previous or next available station. The
unit stops at the next strong signal it finds.
In Manual mode - Allows manual stepping up or down of the frequency.
Note: When Preset mode is activated, the unit will automatically tune to
the first available preset.
Mode/Store button
4
Used for AM/FM mode. Press to cycle the tuning mode between Preset,
Auto, and Manual modes. Pressing and holding the button will allow the
current selected station frequency to be stored in the preset bank. First
press and hold the button then use the   or Preset buttons to select
the preset location for the station to be stored to. Press the Mode/Store
button again to confirm and store the preset.
Note: In 'Store' mode, if no button is pressed for a while, the unit will come
out of 'Store' mode and the preset will not be saved.
Input source buttons
5
Press the relevant source button to select the desired input source.
Note: The FM/AM source is built into the SR20. This button toggles
between the FM mode and AM mode when pressed more than once.
Preset buttons
6
Used for AM/FM modes. The preset buttons are used to select user-stored
station presets. Pressing a preset button once will select one of the first 5
preset, then pressing the same preset button again will toggle to the next
preset (1 and then 6 for instance). These presets are stored separately for
each waveband i.e. there are 10 for FM and 10 for AM press the FM/AM
button to switch between bands and sets of 10 presets.
Note: As well as these 10 per band available directly from the front panel
buttons a further 5 presets (11-15) per band can also be accessed by
using the up/down buttons to cycle through all 15 presets.

Display
7
Used to display information such as the selected input source, volume
and tone/balance levels. When the FM or AM tuner input is selected, the
radio frequency or RDS station name will be displayed.
Note: When first purchased, the display will have a protective film over the
top. Peel this off for a clear display.
Speaker A/B button
8
The Speaker A/B button toggles between the two sets of loudspeaker
terminals. The options are speaker A only, speaker B only, speaker A and
B together, and both sets of speakers off.
Note: 'Speaker off' is different to the mute function, as the Rec Out and
Headphones outputs are still enabled.
9 Menu button
Pressing this once will select the Bass option. Pressing a second time will
select the Treble option and pressing a third time will select the Balance
option. When one of these options is selected, the volume control will
adjust the level. If nothing is pressed for a while, the source will be
displayed and the volume control will go back to controlling the volume
level.
Infrared sensor
10
Receives IR commands from the supplied remote control. An unobstructed
line of sight between the remote control and the sensor is required.
Volume control
11
Use to increase or decrease the level of the sound from the outputs of
the unit. This controls the volume level of the loudspeakers, Sub-out
and headphones. It does not affect the level of the 'Rec Out' output. The
volume control will also change the level of bass, treble and balance in
the menu options.
MP3 input socket
12
This source input allows you to connect a portable audio device such as
an MP3 player directly into the front of the unit using a 3.5mm stereo-
jack. Once plugged in, this input is automatically selected, although other
inputs can still be selected once a stereo-jack is plugged in. The MP3/AUX
button on the front of the unit will select this input whilst a stereo-jack is
plugged in.
Note:
– Plugging a source into the front panel MP3 input overrides the Aux
input. Simply remove the jack from the front panel to automatically
re-enable the Aux input.
– Also note that as the output level of MP3 players tends to be quite low,
the SR20 adds 10dB to the current volume setting when (and only
when) the MP3 input is selected.
