1. INTRODUCTION Congratulations! Now you are the owner of the OEX900 . The OEX900 is a plastic reinforced trolley that includes a versatile mixer with DSP effects, L&R full range speaker cabinets and sub-woofer, and some essential accessories such as power cord, signal cables, speaker cables, and speaker stands. The OEX900 adopts an optimal crossover network and advanced power amplifier technologies, which ensures its incredible versatility and excellent audio performances.
In following picture you see OEX900 most important components.
3. QUICK START Though the OEX900 looks like a super formidable giant, you don't have to worry about how to carry it. As the OEX900 is equiped with two wheels, you can think of it as a trolley. Seeing is believing. Operating this unit, you will find that it is really versatile and user-friendly. Following steps will give you a guide line to set up your OEX900.
After that, set up the system. Note: During this step too the system must be powered off, and , in order to avoid damaging your speakers and/or to produce noise the mixer main volume control should be competently turned off. Connect one side of the speaker cable to the left/right power outputs (speakon connectors) of system, and the other side to the left/right speaker cabinets (speakon connectors), as shown in Fig.6. Warning! Do not connect additional speakers to the powered output.
At the end of your session, put all your levels to zero, turn off your system, then collect all the cables and put them back in their places all accessories into assigned storage compartment. Finally, lay the speakers face down on top of trolley and secure the six latches. Now the OEX900 is ready to be carried everywhere.

(1). MIC IN These electronically balanced XLR sockets have been designed to accept microphone signals, providing low noise microphone pre-amplifier, as well as phantom power for condenser microphone by pressing the PHANTOM power switch. Note: You shall never connect an unbalanced microphone to the XLR socket if you don't want to damage both the microphone and mixer. (2).
(11). MONITOR LEVEL Control This control adjusts the level of monitor output by a range of - to +10dB. (12). MAIN LEVEL Control By rotating this pot you'll simultaneously adjust the overall volume of the left and right main mix outputs in - to +10dB. (13). PRESETS Control (DSP Section) Adjust this knob to select the effect you wish to perform. There are 16 options available: several kinds of reverb, mono and stereo delay, modulation effects, and versatile two-effect combinations. (14).
(28). AC INLET with FUSE HOLDER Standard IEC receptacle, connect your OEX900 to mains with the supplied power cord. (29). POWER Switch It switches on/off the OEX900 main power. (30). Powered Output Connectors These 4-way speakon type connectors are used to output the powered signal to L&R speaker cabinets. Note: in order to avoid damaging your built-in amplifier, please pay attention to speaker impedance. Lower load impedance is not permitted.
