Congratulations! Now you are the owner of the OEX-400S. The OEX-400S is a
plastic reinforced trolley that includes a versatile mixer with DSP effects, L&R
full range speaker cabinets. Besides, this package also includes some essential
accessories such as power cord, signal cables, speaker cables. In order to
ensure high versatility and excellent audio performances, the OEX-400S adopts
optimal crossover frequency and advanced power amplifier technologies.
The L&R speaker cabinets are tightly hooked on the trolley. When you operate
the OEX-400S, first of all take care of the setting of the L&R cabinets . It is
the development of ALTO's experience and knowledge in speakers field, in order
to faithfully reproduce sound for each kind of applications.
Inlaid in OEX-400S panel there's a compact extractable 8-channel mixer, which
adopts 24-bit A/D&D/A converters and 24-bit DSP effects with accurate
algorithms (16 presets). It also provides 4 MIC inputs with ultra low noise
microphone pre-amplifiers, natural 2-band EQ; AUX send/return and 2TK in/out
and optional MP3 and 9 band EQ and so on.
In a word, it is ideally suited for live sound applications, small venues
applications, live recording and many other musical purposes. In order to get
