emory card, CD, radio or aux signal. If playback in USB CARD mode has started and you change to
one of the other available inputs (CD, TUNER, AUX), the USB CARD player is kept in pause so that it can

tart again automatically when it is next chosen.
7.- SURROUND: switch for activating loudspeaker surround output.
8.- RANDOM: allows random playback of MP3 files contained in the USB device or in the SD memory card.
9.- BALANCE: output signal balance control.

0.- 7: after stopping playback, this allows moving among files in the storage device to choose the track
you wish to play. In playback or pause mode, with one short press, you can choose the previous file.
11.- 1/2: to start or pause playback.
12.- BASS: reinforces or attenuates bass frequencies.

1.- INPUT AUX: aux signal input, 2 x RCA connectors.
2.- INPUT TUNER: radio signal input, 2 x RCA connectors.
3.- INPUT CD: CD signal input, 2 x RCA connectors.
4.- SPEAKER OUTPUT SURROUND: loudspeaker surround signal output , RCA connectors. A mono signal
is used for this output. 2 low impedance (8 Ω is recommended) loudspeakers can be connected on the
rear to achieve a spatial effect. To activate this output, the SURROUND switch must be pressed. One
loudspeaker must be connected to channel L and another to channel R due to the internal connection
being in series; otherwise the signal output will not come through just one loudspeaker.
5.- SPEAKER OUT STEREO: stereo signal output for low impedance (4-8 Ω) loudspeakers, spring terminals.
If 4 Ω loudspeakers are connected in the SURROUND output, the minimum impedance of the
loudspeakers connected to this output must be 8 Ω.
6.- 230 V AC/115 V AC: power supply voltage selector.
7.- AC socket: for connecting the AC power cable.
