Depress the mode button for stereo selection on your IEM system. Connect two XLR cables between your IEM system and the mixbus or auxiliary of your sound board. This will send the Left and Right input signals to their corresponding headphone output channels. In Stereo Mode the pan control will adjust the stereo balance.



Press the mode button down for mono selection on your IEM system. When connecting to a mono source, you can connect to either the Left or the Right input. With the mono mode active, the pan control should be turned to the corresponding side (i.e. if your source is connected to the Left input, turn the pan control all the way to the Left side).This will send the signal equally to both headphone channels.



Mono Mode can also be used as an easy way to create a custom monitor mix such as having the band in one channel and your instrument in another. To setup Mono-Mix Mode, press the mode button down, for mono mode selection. Then connect the mix of the band to the left input on your IEM-STEREO and connect the direct output of your channel/instrument to the right. Now the pan control will attenuate the level of either the band mix or your own channel by moving it to the right or left
