Thank you for viewing. Yamaha EMX5014C Powered Mixer It was used in a rack, so I don't think there is any major damage to the exterior. (Some of the fader knobs have different colors) In its current state: Power turns on and sound comes out, but: Input/ Channels 2 and 3 of the cannon jacks do not work. Lines 1, 2, and 3 around that area do not work either. Output/ The left speaker output (Speakon) does not work (both phone jacks and the right Speakon output work). There is a hissing noise even when all the faders are down (acceptable during performance). Effects and master volume are not a problem. There may be other malfunctions, but please purchase with the understanding that this is a completely junk item and is non-refundable and non-returnable. This is for those who can repair it or those who just want to get sound out of it. (I was told by Yamaha that repair is possible) Thank you. - Brand: Yamaha - Model: EMX5014C - Number of Channels: 14 - Input Terminals: XLR and TRS - Output Terminals: Speaker output, Line output - Effects: Built-in effects - Size: Rackmountable - Features: Powered mixer Thank you for viewing.
