The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product´s enclosure that may be of sufficient magnitude to constitute a risk to persons.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION! HIGH VOLUME!
You will operate this transmission system for professional use. Therefore the commercial use of this equipment is liable to the rules and regulations of the Accident Prevention & Insurance Association of your industry sector. Adam Hall as a manufacturer is bound to inform you formally about the existence of eventual sanitary risks.
This system is able to induce an acoustic pressure of 80 db. 85 db is by law the maximum audio pressure level which your ear can be exposed to during a work day. It was set according to the technical expertise of the occupational medicine as a basis for the noise rating level. Higher sound levels or longer exposition times could
damage your ear. The time of exposition by higher sound pressure levels should be shortened in order to prevent from ear damages. Here are a few reliable warning signals which show that you have exposed yourself for a too long period to excessive sound pressure levels:
-You hear bellor whistling sounds!
-You have the impression that you can’t hear high tones anymore!

FEATURES & GETTING STARTED:
INTRODUCTION
Thank you for choosing this LD Systems audio product. The LAX12D is a professional compact mixer. It's smooth, natural sound and precise reproduction make it ideal for gigs, recording, and fixed PA installations. The LAX12D offers some features that are not often found in this price class. The mono channels stand out because of their ultra-low-noise microphone preamps with +48V phantom power. In addition, all channels are equipped with warm and natural sounding equalizers: the mono channels have 3-band EQs (MID: with adjustable centre frequencies), the stereo channels with 4-band EQs with fixed centre frequencies. Moreover, the LAX12D has a highly precise (12-segment) level meter, 2-track inputs that are assignable to both the main mix outputs and the phones/control room outputs, and much more. In addition, the integral 24-bit effects processor provides 100
effects presets. The LAX12D mixer is extraordinarily easy to use. Nevertheless, we recommend that you read this manual carefully before using the product for the first time. This will enable you to get the most out of your mixer.

FEATURES & GETTING STARTED:
FRNCAISITALIANO POLSKIFRANCAIS ESPAÑOL FRANCAIS DEUTSCH ENGLISH
•Before plugging in your LAX12D mixer, make certain that the available AC voltage is suitable for your device.
•Make certain that the mixer is turned off before connecting it to the mains power, and set all controls to "zero".
This will avoid damage to your speakers due to loud power-on noise and high levels.
•Always turn on the mixer first and then the power amplifier.When powering down, the sequence is reversed:
First turn off the power amplifier and then the mixer.
•Always turn off the LAX12D mixer before connecting cables.
•Do not use solvents to clean the LAX12D; use a clean, dry cloth.When powering down, the sequence is reversed: First turn off the power amplifier and then the mixer.
•Always turn off the LAX8D mixer before connecting cables.
•Do not use solvents to clean the LAX8D; use a clean, dry cloth.

CONTROL ELEMENTS:
1MONO CHANNELS (MIC/LINE)
The mono channels offer balanced XLR connectors for low-impedance microphones and other low-level equipment. In addition, there are 6.3 mm TRS jack input connectors for microphones and line level equipment (e.g., synthesizers, drum computers, effects processors, etc.). Important: The MIC and LINE inputs cannot be used simultaneously on the same channel. +48V PHANTOM POWER The XLR inputs on the mono channels provide +48V phantom power for condenser microphones. Important: Never connect a microphone without phantom power to the XLR input when phantom power is on.
2INPUT GAIN ADJUSTMENT
The input gain control has two different scales: one for microphones and one for line level devices.The outer ring (0 ~ 44 dB) refers to microphones, the inner one (+15 ~ -30 dB) to line level devices.Always adjust the gain control so that the peak LED above the channel fader lights up only occasionally. If the LED is on constantly, this can lead to distortion.
3LOW CUT FILTER
The LOW CUT button activates a low cut filter (75 Hz, slope 18 dB/octave) for reducing low-frequency noise such as mains hum or handling noises from vocal microphones.
4STEREO CHANNELS
The stereo channels are configured as stereo pairs with 6.3 mm TRS jack input connectors. Mono signal sources should be connected to the left jack input connector.
5+4dBu/-10dBV SELECTOR
The line inputs of the stereo channels have a button for selecting the input sensitivity (+4 dBu for professional audio equipment, -10 dBV for general hi-fi devices, etc.). If you are uncertain which setting to use for the respectively connected device, first try +4 dBu. If the level is too low, switch to -10 dBv.
6AUX SENDS
These 6.3 mm TRS sockets can be used to split the signal and send it additionally to external effects processors or the like. In addition, these outputs can be used as submix outputs.
7PHONE
Headphones for monitoring the output signal (MAIN MIX) can be connected to this TRS socket.

CONTROL ELEMENTS:
14PAN/BAL
The mono channels of the LAX12D have panorama (PAN) controls and the stereo channels have balance
(BAL) controls, both of which are used to distribute the signal to the right and left output channels.
15MUTE/ALT3-4
Each of the channels of the LAX12D has a MUTE/ALT3-4 switch. This switch can be used to send the signal of the respective channel to the ALT3-4 output.
16SOLO
The SOLO switch lets you hear only the signal of the channel for which the solo function is activated (button pressed) without the other channels. The SOLO switch is especially useful for adjusting input levels (gain adjustment) and as a "preview" option for monitoring the respective signal.
17PEAK LED
All channels of the LAX12D are equipped with a peak LED for monitoring the respective audio signal. If the peak LED lights up (6 dB below the actual clipping threshold), this means that the signal is peaking and distortion may ensue.
18CHANNEL FADER
This fader controls the overall volume of the respective channel, i.e., the level at which the signal is sent to the main mix.
192-TRACK IN/OUT
TAPE IN: Use the TAPE IN input to connect a tape recorder or DAT recorder. Press the 2TK IN button on the front panel to send the signal coming from the connected device to the PHONES/CONTROL ROOM output or the 2TK TO MAIN MIX button to send it to the MAIN MIX output. TAPE OUT: The mix can be output to a tape recorder via these cinch (RCA) connectors. 2TK IN CONTROL: This control is used to adjust the level of the 2TK IN signal, which can be varied from ∞ to MAX.

38INSERTS (MONO CHANNELS)
All mono MIC channels are additionally equipped with Insert sockets (stereo jack, TRS), via which external effects devices or the like can be patched into the respective channel. The signal is sent immediately after the input gain control (TRIM) to an external signal processor, for example, a compressor or limiter. Once the signal has passed through the external signal processor, it is returned to the same channel immediately before the EQ. Note: Connecting external devices to insert points requires a so-called "Y" cable.
39CTRL ROOM OUTPUT
These 6.3 mm sockets are used to send the signal to studio monitor speakers (CONTROL ROOM) or a PA system.
40ALT OUTPUT
These unbalanced 6.3 mm sockets serve as additional outputs. Their level is controlled using the ALT 3-4 fader in the master section of the mixer (max. +22 dBu).The signals of all channels for which the Mute/Alt 3-4 button has been pushed are routed to this bus; they no longer reach the main mix.
41MAIN MIX OUTPUT
The L/R MAIN MIX OUTPUT has both XLR and 6.3 mm TRS sockets via which the main mix output signal can be sent to an amplifier.The output level is controlled by the MAIN MIX LEVEL fader (-∞ to +10 dB).
42FOOT SW
This socket can be used to connect an external footswitch for activation/deactivation of the integral effects processor (function identical with that of the DFX MUTE switch).
43PHANTOM SWITCH
This switch activates the +48V phantom power for the four XLR microphone inputs. Important: Make certain that the phantom power is off before connecting microphones.
44POWER SWITCH
This switch is used to turn the mixer ON or OFF.
45AC INPUT
This socket is used to connect the power adapter.

INSTALLATION AND CONNECTION:
INSTALLATION AND CONNECTION
Now that you have familiarized yourself with the functions of the LAX12D mixer, you should have no trouble using it. Nevertheless, we recommend that you read the following section carefully. It contains important information about how to obtain the best results with your mixer.
-Before connecting mics or instruments, make certain that the channel and MAIN MIX faders of the LAX12D mixer are set to minimum (all the way down).
-Make certain that all external devices such as mics, power amplifiers, speakers, effects processors, etc. are connected properly.
-When running cables, take care not to injure anyone or damage the equipment.
-Set the output level of your mixer and the connected power amplifier to no more than 75%.
-Do not set the PHONE/CONTROL ROOM level higher than 50%.
-Set the EQ controls (HI, MID, LOW) to the middle position.
-Set the PAN/BAL controls to the middle position.
-While speaking into each connected mic (speech or vocals) or playing the instrument, adjust each channel fader (LEVEL) so that the peak LED of the corresponding channel comes on only occasionally. This will ensure that there is always enough headroom and dynamic range available.
-You can shape the sound of the individual signals using the respective channel equalizer.
-Repeat this sequence of steps for all of the input channels being used, always keeping an eye on the LED level meter (OUTPUT LEVEL) so that it does not swing too far into the red area.
AUDIO CONNECTIONS
The LAX12D mixer offers numerous, highly flexible possibilities for balanced or unbalanced connection of your equipment via XLR and 6.3 mm TRS connectors. These are explained below.
WIRING CONFIGURATION
The XLR and 6.3 mm TRS connectors of the LAX12D permit balanced and unbalanced connections depending on the equipment connected. Examples for wiring your system:

FUNKTIONEN & ERSTE SCHRITTE:
•Überprüfen Sie vor Anschluss Ihres LAX12DUSB-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.
•Schalten Sie den LAX12DUSB-Mixer stets aus, bevor Sie Verkabelungen vornehmen.
•Verwenden Sie zur Reinigung des LAX12DUSB keine Lösungsmittel, sondern ein sauberes, trockenes Tuch.

BEDIENELEMENTE:
1DIE MONOKANÄLE (MIC/LINE)
Die 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 Line-Pegel (z.B. Synthesizer, Drum-Computer, Effektprozessoren etc.) zur Verfügung.
Achtung: Es ist nicht möglich, MICund LINE-Eingänge desselben Kanals gleichzeitig zu belegen.
+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.
2EINSTELLEN 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 den Gain-Regler stets so ein, dass die Peak-LED oberhalb des Kanal-Faders nur gelegentlich aufleuchtet. Leuchtet die LED konstant, kann dies zu Verzerrungen führen.
3TRITTSCHALLFILTER (LOW CUT)
Die LOW CUT-Taste aktiviert ein Trittschallfi lter (75 Hz, Flankensteilheit 18 dB/
Oktave) zur Reduzierung von tieffrequenten Störgeräuschen wie Netzbrummen oder Handgeräusche von Vokalmikrofonen.
4DIE STEREOKANÄLE
Die Stereo-Kanalzüge sind jeweils als Stereopaare mit 6,3-mm-Klinkeneingängen (TRS) ausgeführt. Mono-Signalquellen schließen Sie an den linken Klinkeneingang an.
5+4dBu/-10dBV-UMSCHALTUNG
Die Line-Eingänge der Stereo-Kanalzüge verfügen über eine Taste zur
Umschaltung der Eingangsempfi ndlichkeit (+4 dBu für professionelles AudioEquipment, -10 dBV für HiFi-Geräte etc.). Falls Sie nicht sicher sind, welche
Einstellung für das jeweils angeschlossene Gerät geeignet ist, versuchen Sie es zuerst mit +4 dBu. Sollte der Pegel nicht hoch genug sein, schalten Sie auf -10 dBV um.
6AUX SENDS
Über diese 6,3-mm-Klinkenbuchsen kann das Signal gesplittet und zusätzlich an externe Effektprozessoren o.Ä. überführt werden. Darüber hinaus bieten sich diese Ausgänge als Submix-Ausgänge an.
