READY TO START:

Please check the AC voltage available in your country before connecting your mixer to the AC socket.

Be sure that the main power switch is turned off before connecting the mixer to the AC socket. Also, you should

make sure that all input and output controls are turned down. This will avoid damage to your speakers and avoid excessive noise. Always turn on the mixer before the power ampliﬁer; turn off the mixer after the power ampliﬁer.

Before connecting and disconnecting the unit from the power source always turn off the unit.

Do not use solvents to clean your mixer. A dry and clean cloth will be OK.

AUX-CONTROL

These two controls are used to adjust the level of signal sent to AUX bus 1&2,

and this adjustment doesn‘t affect the main mix output signal at all.

AUX1 is congured as PRE fader, the signal is sent out before the channel fader and will not be affected by the channel fader, AUX2 is congured as POST

fader, the signal is sent out after the channel fader and will be affected by the channel fader. However, it can also be conﬁgured as PRE fader through internal modiﬁcation.

7

PAN This is the PANORAMA control, or balance control. You can adjust the stereo image of the signal via this control. Keep this control in center position and your signal will be positioned in the middle of stage. Turn this control fully counterclockwise and the signal will be present only on the left speaker and vice-versa.

8

PEAK-LED

Inside your 8-Channel Mixing Console the audio signal is monitored in several different stages and then sent to the PEAK LED. When this LED blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK LED will blink with a level that is 6dB before actual clipping.

WIRING CONFIGURATION:

Ok, you have got to this point and you are now in the position to successfully operate your 8-Channel Mixing Console. However, we advise you to read carefully the following section to be the real master of your own mixer. Not paying enough attention to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow these procedures for every single channel:

• Before connecting mics or instruments, make sure that the power of all your systems components including

the mixer is turned off. Also, make sure that all input and output controls of your mixer are turned down. This will

ENGLISHDEUTSCHFRANCAIS

avoid damage to your speakers and avoid excessive noise.

• Properly connect all external devices such as mics, power ampliers, speakers, effect processor etc.

• Now, turn on the power of any peripheral devices, then power up the mixer.

Note: the power ampliﬁer or powered monitors shall be turned on after the mixer and turned off before the mixer.

• Set the output level of your mixer or the connected power amplier at no more than 75%.

• Set the CONTROL ROOM/PHONE level at no more than 50%.

• Position HI, MID and LOW EQ controls on middle position.

• Position panoramic (PAN/BAL) control on center position.

• While speaking into the mic(or playing the instrument), adjust the channel Level control so that the PEAK LED

will blink occasionally, in this way you will maintain good headroom and idea dynamic range.

• You can shape the tone of each channel by adjusting the equalizer controls as desired.

• Now repeat the same sequence for all input channels. The main LED could move up into the red section, in this case you can adjust the overall output level through the MAIN MIX control.

• You can select desired DSP sound effects via the PRESET and VARIATION controls.

Mit diesen Lautsprechern können hohe Schalldrücke erzeugt werden. 85db ist der Schalldruck, der laut Gesetz als maximal zulässiger Wert über die Dauer eines Arbeitstages auf Ihr Gehör einwirken darf. Er wird nach den Erkenntnissen der Arbeitsmedizin als Berurteilungspegel zu Grunde gelegt. Höhere Lautstärken oder längere Einwirkzeit können Ihr Gehör schädigen. Bei höheren Lautstärken muss die Hörzeit verkürzt werden, um eine Schädigung auszuschließen. Sichere Warnsignale dafür, dass Sie sich zu lange zu lautem Geräusch ausgesetzt

haben, sind:

- Sie hören Klingel- oder Pfeifgeräusche in den Ohren!

- Sie haben den Eindruck, hohe Töne nicht mehr wahrzunehmen!

ERSTE SCHRITTE:

Überprüfen Sie vor Anschluss Ihres LAX8D-Mixers, dass die Stromversorgung mit der für das Gerät geeigneten

Netzspannung erfolgt.

Vergewissern Sie sich, dass der Mixer ausgeschaltet ist, bevor Sie ihn an das Stromnetz anschließen, und stellen

Sie alle Regler in “Null”-Stellung. Auf diese Weise vermeiden Sie Schäden an Ihren Lautsprechern durch laute Einschaltgeräusche und hohe Pegel. Schalten Sie immer zuerst den Mixer und danach den angeschlossenen Leistungsverstärker ein. Beim Ausschalten gilt die umgekehrte Reihenfolge: Schalten Sie zuerst den Leistungsverstärker und danach den Mixer aus.

ENGLISHDEUTSCHFRANCAIS

Schalten Sie den LAX8D-Mixer stets aus, bevor Sie Verkabelungen vornehmen. Verwenden Sie zur Reinigung des LAX8D keine Lösungsmittel, sondern ein sauberes, trockenes Tuch.

DIE MONOKANÄLE (MIC/LINE)

Die vier Mono-Kanalzüge bieten symmetrische XLR-Anschlüsse für niederohmige Mikrofone und anderes Equipment mit niedrigem Pegel. Zusätzlich stehen

6,3-mm-Klinkeneingänge für den Anschluss von Mikrofonen und Geräten mit

1

Line-Pegel (z.B. Synthesizer, Drum-Computer, Effektprozessoren etc.) zur Verfügung. Achtung: Schließen Sie niemals unsymmetrische Mikrofone an die XLR-Eingän-

ge an, da auf diese Weise sowohl die Mikrofone als auch der Mixer beschädigt

werden können. Darüber hinaus ist es nicht möglich, MIC- und LINE-Eingänge desselben Kanals gleichzeitig zu belegen. Verschiedene Signalquellen erfordern

separate Kanäle.

2

+48-VOLT-PHANTOMSPEISUNG

Die XLR-Eingänge der Mono-Kanalzüge stellen +48-Volt-Phantomspannung zur

Speisung von Kondensatormikrofonen bereit. Achtung: Schließen Sie bei eingeschalteter Phantomspeisung niemals Mikrofone

ohne Phantomspeisung an die XLR-Eingänge an.

2

EINSTELLEN DER EINGANGSVERSTÄRKUNG

Der Gain-Regler verfügt über zwei unterschiedliche Einteilungen: eine für Mikrofone und eine für Geräte mit Line-Pegel. Der äußere Ring (0 ~ 44 dB) bezieht sich auf Mikrofone, der innere (+15 ~ -30 dB) auf Geräte mit Line-Pegel.

Stellen Sie die Gain-Regler stets so ein, dass die Peak-LED oberhalb des

4

Kanal-Faders nur gelegentlich auﬂeuchtet. Leuchtet die LED konstant, kann dies zu Verzerrungen führen.

3

TRITTSCHALLFILTER (LOW CUT)

Die LOW CUT-Taste aktiviert ein Trittschalllter (75 Hz, Flankensteilheit 18 dB/

Oktave) zur Reduzierung von tieffrequenten Störgeräuschen wie Netzbrummen

oder Handgeräusche von Vokalmikrofonen.

3-BAND-EQUALIZER HI Über diesen Regler steuern Sie die hohen Frequenzen, d.h. Sie können dem

entsprechenden Signal mehr Brillanz und Präsenz verleihen oder unerwünscht laute hohe Frequenzen absenken (Regelbereich -15 dB bis +15 dB, Mittenfre-

quenz 12 kHz).

MID Über diesen Regler steuern Sie die mittleren Frequenzen, die wichtigsten Fre-

quenzen für Musikinstrumente und die menschliche Stimme (Regelbereich -12 dB bis +12 dB, Mittenfrequenz 2,5 kHz).

LOW

Über diesen Regler steuern Sie die tiefen Frequenzen, d.h. Sie können z.B. einer Bassdrum, Bassgitarre oder männlichen Stimme mehr Fundament verleihen (Regelbereich -15 dB bis +15 dB, Mittenfrequenz 80 Hz).

6

AUX-REGLER

Über diese beiden Regler steuern Sie die an die AUX-Wege 1 und 2 (Ausspielwege) gesendeten Signale. Das Summensignal (MAIN MIX) bleibt unbeeinusst. AUX 1 kann über die PRE/POST-Taste PRE- oder POST-Fader geschaltet werden. In Position POST (Taste nicht gedrückt) erfolgt der Signalabgriff nach dem Kanal-Fader, so dass sich die für diesen Kanalzug eingestellte Lautstärke auch auf das AUX 1-Signal auswirkt. In Position PRE (Taste gedrückt) erfolgt der Signalabgriff vor dem Kanal-Fader, das AUX 1-Signal bleibt also vom KanalFader unbeeinusst. Bei AUX 2 handelt es sich um einen “Post-Fader”-Weg.

7

PAN

Die Mono-Kanalzüge des LAX8D verfügen über einen Panorama-Regler (PAN), die Stereo-Kanalzüge über einen so genannten Balance-Regler (BAL), die beide der Verteilung des Signals auf den rechten und linken Ausgangskanal dienen.

8

PEAK-LED

Inside your 8-Channel Mixing Console the audio signal is monitored in several different stages and then sent to the PEAK LED. When this LED blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK LED will blink with a level that is 6dB before actual clipping.
