3. QUICK START

Though the OEX600 looks like a super formidable giant, you don't have to worry about how to carry it. As the OEX600 is equipped with two wheels, you can think of it as a trolley. Operating this unit, you will find out that it is really versatile and user-friendly. Following steps give you a guide line to set OEX600. Make all connections with the system powered off.

First of all extract the F8 folding speaker stands from their compartment, as shown in Fig.1. Then unhook the L&

R cabinets from the trolley in the right direction as shown in Fig.2.

Note: Please remove the speakers in the right direction, unsuitable operation may damage your equipment. In order to prevent equipment damage, please place the speaker stands on a solid, even surface.

Fig.1

Fig.2

Fix the L&R speaker cabinets on their stands, as shown in Fig 3.

Note: Position the speakers facing the audience and, in order to avoid feedback, far away from the microphones.

Then, properly position the sub-woofer(trolley).

Fig.3

Depending on application requirements, you can disassemble or not the mixer from the trolley. For this application is supplied a 2m. signal cable, as shown in Fig.4.

Fig.4

5

Now you can setup the system.

Note: Make all initial connections with the system powered off, and, in order to avoid damaging your speakers and to have too much noise, with mixer main mix volume control completely turned down.

Connect one side of the speaker cable to the left/right power outputs (1/4"TS jacks) of system, and the other side to the L/R speakers cabinet (1/4"TS jacks), as shown in Fig.5.

Warning! Do not connect additional speakers to the powered output. The system speakers provide the optimal load for the built-in amplifier. In order to avoid damaging your built-in amplifier, please pay attention to speaker impedance.

Fig.5

Connecting Microphone, CD players, Tape, MD player (Line sources) etc. to the appropriate MIC/LINE mixer input connector (XLR/1/4"TRS jacks), as shown in Fig.6.

Fig.6

Now you can turn on the power switch.

Turn up the volume control, use the PFL function to get the proper input level for each mixer channel, then adjust the main mix level control to manage the output level.

6

At the end of your session, put all your levels to zero, turn off your system, then collect all the cables and put back in their places all accessories into their own storage compartment. Finally, lay the speakers face down on top of the trolley and secure the six latches. Now the OEX600 is ready to be safely carried.

The following figure(Fig.7) gives you a representation of connection / installation of your sound reinforcement system.

In order to get the best results and equipment durability, please be careful during all the former operations.

(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 when pushing ON 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). LINE IN

These balanced 1/4"TRS jacks have been designed to accept line level inputs such as keyboards outputs, CD players,

MD/ tape outputs, etc...

(3). Stereo Input

This channel is equipped with two1/4"TRS jacks for stereo input. Connecting the left input jack only, the input will operate in mono mode.

(4). -20dB PAD

Pressing this button the input signal will be attenuated by 20dB. In such way you'll obtain increased headroom simultaneously reducing the risk of distortion due to input level peaks with too high input signals.

(5). Equalizer

Each channel is equipped with 3-band warm, natural EQ: HI, MID and LOW bands, which allows to shape the sound of program material in a very efficient way.

HI

Treble control. You can use it to get rid of high frequency noises or to boost the sound of cymbals or human voice high harmonics. The gain range can be varied from -15dB to +15dB with a center frequency of 12kHz.

MID

Midrange control. It can affect most fundamental frequencies of all musical instruments and human voice. A careful use of this control will provide you an interesting panorama of sound effects. The gain range can be varied from -12dB to +12dB with a center frequency of 2.5kHz.

LOW

Bass control. It can boost male voice or kick-drum and bass guitar. Your system will seem much bigger than what it is. The gain range can be varied from -15dB to +15dB with a center frequency of 80Hz.

(6). AUX Sends

Both these controls are used to adjust the level of signal sent to AUX buses. These sends controls are adjustable in to +15dB range.

The AUX1 control is configured PRE-FADER, it means that the signal is independent by channel fader setting.

It is suited to be used as monitor mix in a live sound mixing, or for headphone mix in recording application.

The AUX2 control is configured as POST-FADER, it means that the audio signal will be affected by channel fader.

This signal is assigned to onboard DSP (digital effects module). Via the AUX2 OUT jack, the AUX2 signal can also be assigned to an external effect device.

(7). PAN/BAL Control

It controls the channel signal position between left and right in the stereo bus. Of course you can use it also to

"move" the channel signal in stereo front to create spatial effects.

(8). LEVEL Control

This pot provides smooth level changes control.

(9). AUX2 TO AUX1 Control

This control adjusts the amount of the signal from AUX REUTRN2 to AUX SEND1 in a range from to +15dB.

(10). AUX RTN1 Control

This control adjusts the amount of AUX RETURN1 signal to master in to +15dB range.

9

(11). PHONES/CTRL ROOM Control

It adjusts control room speakers and headphones volume.

(12). 2TK IN Control

This pot adjusts the level of 2TK IN signal.

(13). 2TK TO CTRL ROOM Switch

Engaging this button the 2TK IN signal will be routed to control room output.

(14). 2TK TO MIX Switch

(15). OUTPUT LEVEL LED Display

The stereo 12-segments LED meter indicates the signal level sent to CTRL ROOM and PHONES outputs.

(16). PWR LED Display

It indicates the OEX600 is powered on.

(17). MAIN MIX LEVEL Dial

Rotating this dial you will to adjust the overall volume of the left and right main mix outputs. The adjustable range is from to +15dB.

(18). PRESETS Control

Through this knob you can select the effect that you desire to use.

There are16 effects options to choose from: several kinds of reverb, effects with modulation, and some versatile two-effect combination. Please refer to chapter 5.

(19). AUX RTN2 (DFX) Control

This pot adjusts the signal coming from an external/internal effect device in to +15dB range.

(20). DSP MUTE Switch

This switch is used to activate/deactivate the built-in effect section.

(21). CLIP LED

This LED lights up when the input signal is too strong. This LED is lit also when the built-in digital effect section is muted.

(22). 2 TRACK IN/OUT

These RCA connectors can be used to connect the output/input of a DAT, cassette or tape recorder.

(23). AUX SEND

These two1/4" phone jacks output the line signal from the AUX bus.

(24). AUX RTN

These four1/4" phone jacks return the signal from external effect units to the main mix bus, you can also use these connectors as line level extra inputs. AUX RETURN2 is connected to internal DSP output, but this path will be broken inserting external signal connectors to AUX RETURN2 socket.

(25). FOOT SW.

This 1/4" phone jack can be used to connect an external foot-switch to turn on/off the built-in effect module.

(26). HEADPHONE
