On the 1/4" phone jack you can connect either a microphone or a line level instrument. You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the microphone and the mixer. 48 Volt phantom power J.T. 2 1 3 1 2 BAL OR UNBAL It is available only to the XLR Mic sockets.

In the AMX-140FX model, excluding sending out directly to the external effect or processor equipment, the AUX SEND2 will also be sent to the internal onboard effect module. 11 4.8 PAN/BAL Control Abbreviation of PANORAMA control for mono channels, for the stereo channels, always says, BALANCE control. You can adjust the stereo image of the signal via this control. Keep this control in center position and your signal will be positioned in the middle of stage.
4.16 2TK IN Control 20 This control is used to adjust the level of 2TK IN signal, which can be varied from - 4.17 PHONES/CTRL ROOM Control to MAX. 21 This control sets the amount of signal sent to the control room and headphone. 22 As implied in the name, the auxiliary returns are used to 'return' the signal from the external effects or processors to the main mix, but, most of the times, it can also be worked as the additional stereo line inputs.
4.23 24 BIT DIGITAL EFFECTS (For AMX-140FX Model) - PRESETS Control 28 Adjust this knob to select the right effect you wish to perform. There are total 16 options for you: several kinds of reverb, mono and stereo delay, effects with modulation, and versatile two-effect combination.

5. INSTALLATION AND CONNECTION Ok, you have got to this point you are now in the position to successfully operate your AMX-140(FX). However, we advise you to read carefully the following section to be the real master of your own mix. Not paying attention enough to the Input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all.
5.1 SOME FINAL TIPS ON WIRING CONFIGURATION You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.
Ring=Return Signal (Connected together) To Channel Insert Sleeve=Ground/Screen Tip=Signal To Tape or FX Input Sleeve=Ground/Screen 'Tapped' Connection Direct Output Lead (Enables the Insert to be used as a Direct Output while maintaining the channel signal flow) To Processor Input Sleeve=Ground/Screen Tip=Send Signal Tip To Channel Insert Sleeve Ring Ring=Return Signal To Processor Output -Stereo lead for insert Connection (To be used when the processor does not employ a single jack connection
6. FOR THE EXPERTS WHO WANT TO KNOW MORE As we have told you previously in this manual, the AUX SEND2 control both on mono and on stereo channels is factory wired as POST-FADER. If you have some skill in electronic components soldering you can modify this setting and have all your AUX SENDS configured as PRE-FADER.
