·Power Supply

The apparatus should be connected to the power supply only of the type as marked

on the apparatus or described in the manual. Failure to do could result in damage

to the product and possibly the user.

Unplug this apparatus during lightning storms or when unused for long periods

of time.

·Ventilation

Do not block areas of ventilation opening. Failure to do could result in fire. Always

install accordance with the manufacturer's instructions.

·Fuse

To prevent the risk of fire and damaging the unit, please use only of the

recommended fuse type as described in the manual. Before replacing the fuse,

make sure the unit turned off and disconnected from the AC outlet.

·Electrical Connection

Improper electrical wiring may invalidate the product warranty.

·Cleaning

·Object and Liquid Entry

Clean only with a dry cloth. Do not use any solvents such as benzol or alcohol.

·Servicing

Do not implement any servicing other than those means described in the manual.

Refer all servicing to qualified service personnel only.

·Only use accessories/attachments or parts recommended by the manufacturer.

·Warning

Please remember the high sound pressure do not only temporarily damage your

sense of hearing, but can also cause permanent damage. Be careful to select a

suitable volume.

Objects do not fall into and liquids are not spilled into the inside of the apparatus

for safety.

·Power Cord and Plug

Protect the power cord from being walked on or pinched particularly at plugs, convenience

receptacles, and the point where they exit from the apparatus.

Do not defeat the safety purpose of the polarized or grounding-type plug. A

polarized plug has two blades with one wider than the other. Agrounding type

plug has two blades and a third grounding prong. The wide blade or the third

prong is provided for your safety. If the provided plug does not fit into your outlet,

refer to electrician for replacement.

Please note that all unit must be properly grounded. For your own safety, you should never

remove any ground connectors from electrical devices or power cables, or render them

inoperative.

Please sure that only qualified people install and operate the mixing console.During

installation and operation, the user must have sufficient electrical contact to earth,

otherwise electrostatic discharges might affect the operation of the unit.

4.1 Mains connection

You will need a larger number of cable for the various connections to and from the console. The

illustrations below show. The wing of these cables. Be sure to use only high-grade cable.

Please use commercial RCAcables to wire the 2-track inputs and outputs.

You can, of course, also connect unbalanced devices to the balanced input/outputs. Use either mono

plugs, or ensure that ring and sleeve are bridged inside the stereo plug (or pins 1 & 3 in the case of XLR

connectors).

Caution! Never use unbalanced XLR connectors (PIN 1 and 3 connected) on the MIC input

connectors when using the phantom power supply.

4.INSTALLATION

Connect the power supply to the 3-pin mains connector on the rear of the console. Use the AC adapter

supplied to connect the console to the mains. The adapter complies with all applicable safety standards.

Please use only the power supply unit provided with the console.

4.2 Audio connections

The circuitry of the British EQs is based on the technology used in the bast-known top-of-the-line consoles

and providing a warm sound without any unwanted side effects. The result are extremely musical equalizes

which, unlike simple equalizers, cause no side effects such as phase shifting or bandwidth limitation, even

with extreme gain settings of +15 dB.

All mono input channelsinclude a 3-band equalizer. All bands provideboost or cut of up to 15 dB. In the

central position, the equalizer is inactive.

The upper (HI) and the lower band (LO) are shelving filters that increase or decrease all frequencies above

or below their cut-off frequency.The cut-off frequencies of the upper and lower band are 12 kHz and 80 Hz

respectively. The mid band (602/802/1002/1202) is configured as a peak filter with a center frequency of

2.5kHz

Inaddition, the monochannels are equippedwitha steepLOW CUT filter

designedto eliminate unwanted low-frequenty signalcomponents. Thesecanbenoisecreated byband-held

microphones,subsonicnoiseorplosivesoundscreatedbyhighlysensitivemicrophones.

The scale has 2 different value range: the first value range (+10 to +60 dB) refers to the MIC input and

shows the amplification for the signals fed in there.

The second value range (+10 to +60 dB) refers to the line input and shows its sensitivity. The settings

for equipment with standard line-level signals (-10dB or +4dBu) look like this: While the TRIM control is

turned all the way down, connect your equipment. Set the TRIM control is turned to the external devices

standard output level. If that unit that an output signal level display, it should show 0 dB during signal

peaks. For +4 dBu, turn up TRIM sightly. for -10 dBV a bit more.Tweaking is done using the CLIPLED.

Each mono input channel offers a balanced microphone input via the XLR connector and also

features switchable +48 V phantom power supply for condenser microphones. The ME preamps

provide undistorted and noised-free gain as is typically known only from costly outboard preamps.

The PAN control determines the position of channel signal within the stereo image. This control features a

constant-power characteristic, which means the signal is always maintained at a constant level, irrespective

of position in the stereo panorama.

PAN

The LEVEL control determines the level of the channel signal in the main mix

LEVEL

The CLIP LED”s of the mono channels illuminate when the input signal is driven too high, which could

cause distortion. If this happens, use the TRIM control to reduce the preamp level until the LED does not

light anymore.

CLIP

2.2 Stereo channels

As the name suggests, the FX sends of the MX mixingconsoles are intended to drive effects devices(reverb,

delay, etc.) and are therefore configured post-fader. This means that the mix between dry signal and effect

remains at the level determined by the channel’s aux send, irrespective of the level fader setting. If this were

not the case, the effects signal of the channel would remain audible even when the fader is lowered to zero.

With ME mixing consoles the channelfader is called LEVEL control.

In the MX-6-FX/ MX-8-FX /MX-6-FXU/ MX-8-FXU, the FX send is routed directly to the built-in effects processor.To

make sure that the effects processorreceives an input signal, you should not turn this control all the way to

the left (-∞).

Attention: Since the FX path for the effect processor is connected post-fader, the LEVEL

control has to be turned up in order to get this channels signal to the effects processor!

The FX SEND connector outputs the signal you picked up from the individual using the FX controls. You

can connect this to the input of an external effects device order to process the FX bus master signal. Once

an effects mix is created, the processed signal can then be routed from the effects devices outputs back into

a stereo input

Astereo EQ is highly preferable to two mono equalizers. when working on a stereo signal, as two

separate Eq”s will usually produce anunwanteddiscrepancybetween the left and right channels.

Each stereo channel has two balanced line level input on connectors for left and right channels. If

only the connector marked “L”(left) is used, the channel operates in mono. Stereo channels are designed

to handle typical line level signals. Both inputs will also accept unbalanced connectors.
