IMPORTANT
Always select the “CARD-USB” mode first (using
“FUNCTION” key) before inserting a USB flash drive.
Please note that this unit is only compatible with USB-pen-
drivers, but not “USB-MP3-players”. (However, some USB-
MP3-player may function with unit properly – please test
your USB-MP3-player to see if it works. If not, you can also
connect it to this unit through the “AUX-IN” input-jacks from
the headphone socket of your USB-MP3-player (you will
need a headphone jack-to-RCA type standard audio cable,
not included).
6.5. Subwoofer output (external powered subwoofer)
This unit has a built-in subwoofer connection which can be
connected to any standard powered subwoofer.
By connecting to a powered subwoofer, the low frequency (bass
sound) can be strongly enhanced to provide a much richer and
deeper sound to your music.
To use this facility, simply connect any standard powered
subwoofer using the RCA jack on the rear panel of the main
unit.
Switch on the powered subwoofer and play any music
source as usual.
You will immediately notice the deeper sound. This can be
further enhanced by switching on the Bass function on the
main unit.
Please note that the speakers should be connected as usual
to the main unit, when using a subwoofer.
NOTE
Please note that “passive” (non-powered) subwoofers will not work
with this unit.
