ENGLISH
1. [LEVEL]: Adjusts the input level on each channel. Use this control to adjust the level on the VU-meter at
about 0dB.
2. CHANNEL VU METER: Each channel has its own LED VU-meter so you can adjust the gain level (1)
very quickly. Make sure the levels do not exceed 0dB (or 100%). The audio risks to be distorted when
the signal level comes in the red zone of the VU-meter.
3. INPUT SOURCE SELECTOR: Used to select the correct input on each channel: Phono, line, USB, aux
or CD. There are also additional input selectors on the back.
Hint: Line, Aux, CD, Tuner, etc... are different names for inputs with almost the same signal levels.
4. [TALKOVER]: Use the switch to automatically mute the input channels 1 to 4 while you are talking
through a microphone connected to [MIC 1], [MIC 2] or [MIC 3]. You can adjust the amount of muting on
input channels 1 to 4. The more you turn the talkover level to the right, the more these channels are
muted while talking through one of the microphones connected to [MIC 1], [MIC 2] or [MIC 3].
5. [AUX]: 3.5mm stereo mini-jack input to connect external sources (for example : smartphone, tablet or
PC). This input is controlled by channel 4. Connecting an external source will take priority over the
internal player.
6. [BALANCE]: used to adjust the balance between left and right output on the [Master].
7. [POWER]: The blue led is lit when the mixer is turned on.
8. [MASTER] VU METERS: Monitors the output level of the [master]. Make sure the levels do not exceed
0dB (or 100%). The audio will be distorted when the signal level comes in the red zone of the VU-meter.
9. [MASTER]: Used to adjust the level of the balanced [Master] output.
10. [BOOTH]: Used to adjust the level of the unbalanced [BOOTH] output.
11. [SD-CARD READER]: for the use of SD cards (max. 16GB – FAT 32). The card reader is controlled by
channel 4. The inserted SD card will have priority above the USB memory stick. It is NOT possible to use
both SD card and USB stick simultaneously.
12. [USB socket]: for the use of USB memory sticks (max. 16GB – FAT 32) with a one level folder structure
for replay of WMA, WAV and MP3 files. Note that this socket does NOT support USB hard drives,
neither for memory size nor for power requirements. The USB memory stick is controlled by channel 4.
13. Display: shows information such as playing time, track name, ...
A. Time Display: shows elapsed/remaining
time while the media player is used.
B. Elapsed time: is displayed while "E" is lit.
C. Remaining time: is displayed while "R" is lit.
D. Not used!
E. 8-Digit Text Readout: The file name of the
currently playing track is shown, with its first
30 digits scrolling through the display. Note
that this is NOT an ID3 tag readout, but a file
name readout, so files must be named
properly to yield a sensible displayed
content. The display will show the file name
and alternate with the folder name the current file is located in. Whether at a specific time the file
or the folder name is displayed, is indicated by the respective symbols (F/G)
F. Folder Name Display Indicator: This indicator shows that the current content of the text
readout (E) is a folder name.
G. File Name Display Indicator: This indicator shows the current content of the text readout (E) is
a file name.
H. FM-indicator: Not used!
I. Play Sequence Indicator: This indicator shows whether the unit is set to straight sequential or
random play sequence. The setting can be altered by the play sequence button (15).
J. Play Mode Indicator: Based on the selection made by the play mode button (14), this part of
the display shows the letters "SPL", "SLO", "ACO" or ALO".
K. Player status: shows if the player is in play, pause or stop mode. See play/pause button (16).
14. Play mode selector: Selects between the different playback modes of the media player:
 SPL = Single Play: The player stops after playing the current song once.
 SLO = Single Loop: The player loops the current song endlessly.
 ACO = All Continuous: The player continues after playing the current song. The next song is
determined by the chosen sequence. The player stops after the sequence is executed once.
 ALO = All Loop: The player continues after playing the current song. The next song is
determined by the chosen sequence. The player repeats the sequence endlessly.
This selected play mode is displayed in the display (J).
