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.
2.CONTROL ELEMENTS AND
CONNECTORS

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.

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.

The SIGNALLED on the effects module shows the presence of a signal whose level is high enough. This
LED should always be on. However, make sure that the CLIPLED lights up only sporadically.
If it is constantly, you are overdriving thr effects processor, which leads to unpleasant distortion.
If this occurs, turn the FX controls down somewhat.

features a built-in digital stereo effects processor. This effects
processor offers a large number of standard effects such as Hall, Chorus, Flanger, Delay and various
combination effects. Using the FX control, you can feed signals into the effects processor. The integrated
effects module has the advantage of requiring no wiring.This way, the danger of creating ground loops or
uneven signal levels is eliminated at the output, completely simplifying the handing.

The FX TO MAIN control feeds the effects signal into the main mix. If the control is turned all the way

To correctly set the gains of the channels, first set the LEVELcontrols of the input channels to their center
positions (0 dB)Then use theTRIM controls to increase the input amplification until signal peaks show 0 dB
on the level meter.
When recording to digital recorders, the recorder s peak meter should not go into overload. While analog
recorders can be overloaded to some extent, creating only a certain amount of distortion (which is common
and often desirable), digital recorders distort quickly when overloaded. In addition, digital distortion is not only
undesirable, but also renders your recording completely useless.
The peak meters of your MX dis play the level virtually independent of frequenc y. A rec ording
level of 0 dB is recommended for all s ignal types .
When recording to an analog device. the VU meters of the recording machine should reach approx. +3 dB
with low-frequency signals (e.g. kick drum). Due to their inertia VU meters tend to display too low a signal level
at frequencies above 1 kHz.This is why, for example, a Hi-Hat should only be driven as far as -10 dB. Since
drums should be driven to approx 0 dB.
