(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). 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 two 1/4" TRS jacks for stereo input. Connecting the left input jack only, the input will
operate in mono mode. Furthermore, it also provides the XLR connector for MIC input. The OEX900 is provided
with two stereo channels.
(4). 20dB PAD
Pressing this button the input signal will be attenuated by 20dB. In such way you'll obtain increased headroom
and you"ll reduce the risk of distortion due to input level peaks with too high input signal.
(5). Equalizer
Each channel is equipped with 3-band warm, natural EQ: HI, MID and LOW bands will allows you 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 and human
voice higher 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 give you a very wide panorama of sound effects. The gain range can be varied from
-15dB to +15dB 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 it really
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 contrals are adjus-

by channel fader setting. It is suited to be used as monitor mix in a live sound mixing, or for a 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 settings. This signal is assigned to onboard DSP(digital effects module). Via AUX2 OUT
connector the AUX2 signal can be sent to an external effect device.
(7). PAN/BAL Control
The pot controls the channel's position between left and right in the stereo bus. Of course you can use it to"move"
the channel signal in stereo front to create spatial effects as well as.
(8). LEVEL Control
This pot provides smooth control over levels.
(9). OPERATING LED Display
The LED indicates when OEX900 power is switched ON.
(10). Graphic EQ
OEX900 is provided with two graphic EQs, one for MAIN MIX, the other for MONITOR MIX. These graphic EQ have
7-band fader controls. Via these faders, you can boost or attenuate the selected frequency by 15dB at a preset
bandwidth.
