24- BIT MULTI -EFFE CTS PRO CESSO R
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 signa ls with the monitor mix.
The main difference is that the mi x radio is a djusted using the
FX TO MON control. Of co urse, a signal has to be fed into the
effects proces sor via the FX control in the channel str ip for both
applicatio ns.
Here you can find a list of all presets stored in the multi-effects
processor. This built-in effects module produces h igh-grade
standard effects such as reverb, chor us, flanger, delay and
various combinat ion effects. The integrated effects module has
the ad vantage of requiring no wiring. This way, th e danger of
creating ground loops or uneven sig nal level is eliminated at the
out set, co mplet ely sim plify ing the h andin g.

The MX Series mixing consoles are equipped with a state-of-theart 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.

MUTE switch. This can be used to rout e a subgroup to a further
mixing console for example, or it could be used as a recording
output working in tand em with the main output. This means you
could record to four tracks s imultaneously. Th e icing on the
cake, so to speak, is that you could connect Y-cables to these
four outp uts and then connect your 8-track record er in such a
way that you have 2 x 4 tracks. (E.g. Channel 1 feeds track 1and
track 2, etc. ). In the first reco rding pass, you record on track 1,

lights up at peak levels. I f it is lit constantly, you are overloading
