24-BIT MULTI-EFFECTS PROCESSOR
These effect presets are designed to be added to dry signals.
If you move the FX TO MAIN control, you mix the channel signal
(dry) and the effect signal.
This also goes for mixing effects signals with the monitor mix.
The main difference is that the mix radio is adjusted using the
FX TO MON control. Of course, a signal has to be fed into the
effects processor via the FX control in the channel strip for both
applications.
Here you can find a list of all presets stored in the multi-effects
processor. This built-in effects module produces high-grade
standard effects such as reverb, chorus, flanger, delay and
various combination effects. The integrated effects module has
the advantage of requiring no wiring. This way, the danger of
creating ground loops or uneven signal level is eliminated at the
outset, completely simplifying the handing.
1.INTRODUCTION
Congratulations! In purchasing the LONGERDB MX you have
acquired a mixer whose small size belies its incredible versatility
and audio performance.
The microphone channels feature high-end Mic Preamps
that compare well with costly outboard preamps in terms of
sound quality and dynamics and boast the following features.
＊
130dB dynamic range for an incredible amount of headroom
＊
crystal-clear reproduction of over the finest nuances
A bandwidth ranging from below 10 Hz to over 200 kHz for
＊
guarantees absolution natural and transparent signal
reproduction
The extremely low-niose and distortion-free circuitry
＊
microphone with up to 60 dB gain and +48 volt phantom
power supply
They are perfectly matched to every conceivable
＊
of your. 24-bit/192 kHz HD recorder to the full. Thereby
maintaining optimal audio quality
They enable you to use the greatly extended dynamic range
The equalizers used for the MX Series are based on the
legendary circuitry of top-notch consoles made in Britain,
which are renowned throughout the world for their incredibly
warm and musical sound character. Even with extreme gain
settings these equalizers ensure outstanding audio quality.
Additionally, your MX Series mixing consoles has an effects
processor with 24-bit A/D and D/A converters included, which
gives you 100 presets producing first-class reverb, delay and
modulation effects plus numerous multi-effects in excellent
audio quality.
The MX Series mixing consoles are equipped with a state-of-the-
art switched-mode power supply (
SMPS
). Unlike conventional
circuitry an SMPS provides an optimum supply current regardless
of the input voltage. And thanks to its considerably higher efficiency
a switched-mode power supply uses less energy than conventional
power supplies.
The USB interface supplied with the unit is a perfect match for
the MX Series and serves as a powerful recording interface to you
PC or MAC. It supports the digital transmission of signals on up to
four channel with max 48 kHz and extremely low latency. When
wired to the CD/TAPE INPUT and OUTPUT connectors,t he interface
transfers the stereo mix from the console directly to a computer.
Both the recording signals and the playback signal from the computer
can be monitored at the same time.I n this way, you can use several
recording runs to produce complete multi-track recordings.

mixing console technology. With the new microphone preamps
including phantom power as an option. Balanced line input and
a powerful effects section. The mixing consoles in the MX Series
are optimally equipped for live and studio applications. Owing
to state-of-the-art circuitry your MX console produces a warm
analog sound that is unrivalled. With the addition of the latest
digital technology these base-in-class consoles combine the
advantages of both analog and digital technology.
The MX Series represents a milestone in the development of

MX Series Mixer
Use the high-precision quality faders to control the output level
of the Alt 3-4 subgroup and main mix.
MAIN OUTPUTS
The MAIN outputs carry the MAIN MIX signal and are on
balanced XLR connectors with a nominal level of +4dBu.
7
ALT 3-4 OUTPUTS
The ALT 3-4 output are unbalanced and carry the signals of
the channels that you have assigned to this group using the
MUTE switch. This can be used to route a subgroup to a further
mixing console for example, or it could be used as a recording
output working in tandem with the main output. This means you
could record to four tracks simultaneously. The icing on the
cake, so to speak, is that you could connect Y-cables to these
four outputs and then connect your 8-track recorder in such a
way that you have 2 x 4 tracks. (E.g. Channel 1 feeds track 1and
track 2, etc.). In the first recording pass, you record on track 1,
3.5 and 7 and in the second pass, on tracks 2, 4, 6 and 8.

1.1 general mixing console functions
A mixing console fulfils three main functions:
＊
Signal processing
:
Preamplification, level adjustment,
mixing of effects. Frequency equalization.
＊
for effects processing and monitor mix, distribution to one
or several recording tracks, power amp(s), control room
and 2-track outputs.
Signal distribution
: Summing of signals to the aux sends
＊
positioning of the individual signals in the stereo field, level
control of the total mix to match the recording devices/
crossover/power amplifier(s). All other mixer functions can
be included in this main function.

PHANTOM
The PHANTOM switch activates the phantom power supply
for the XLR connectors of the mono channels which is required
to operate condenser microphones. The red +48 VLED lights up
when phantom power is on. As a rule, dynamic microphones
can still be used with phantom power switched on, provided
that they are wired in a balanced configuration. In case of doubt,
contact the microphone manufacturer!
After the phantom power supply has been switched
on, do not connect microphones to the mixer (or the
stagebox/wallbox). Connect the on. In addition, the
monitor/PA loudspeakers should be muted before
activating the phantom power supply. After switching
on, wait approx. One minute to allow the system to
Stabilize.
Caution! You must never use unbalanced XLR
connectors (PIN 1and 3 connected) on the MIC
