1.INTRODUCTION

   Congratulations! In purchasing the MX you have acquired a mixer whose small size 
incredible versatility and audio performance.

belies its 

    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

    nuances.

 A bandwidth ranging from below 10Hz to over 200kHz for crystal-clear reproduction of over the finest

    signal reproduction.

 The extremely low-niose and distortion-free  circuitry guarantees absolution natural and transparent

    phantom power supply. 

 They are perfectly matched to every conceivable microphone with up to 60 dB gain and +48 volt

    the full. Thereby maintaining optimal audio quality.

 They enable you to use the greatly extended dynamic range of your. 24-bit/192kHz HD recorder to 

    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 PMX Series mixing consoles has an effects processor with 24-bit A/D and D/A con-
verters included, which gives you 100 presets producing first-class reverb, delay and modulation effects 
plus numerous multi-effects in excellent audio quality.   

    The PMX 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.

USB/Audio interface

Mutil-effects processor

“Bitish EQ”

    The MX Series represents a milestone in the development of 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 
of both analog and digital technology.

digital technology these base-in-class consoles combine  the advantages

PMX Series Mixer

    The USB interface supplied with the unit is a perfect  match  for the PMX 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  48kHz  and extremely low latency. When wired to the CD/TAPE INPUT and 
OUTPUT connectors, the 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. In 
this way, you can use several recording runs to produce complete multi-track recordings.  

We should like to draw your attention to the fact that extreme volumes may damage your 
hearing and/or your headphones or loudspeakers. Turn the MAIN MIX faders and phones 
control in the main section fully down before you switch on the unit. Always be careful to 
set the appropriate volume.
