3-channel digital sampler DJ mixer with 12-second sampling function. - Model: DX 500 - Brand: BEHRINGER - Input/Output Terminals: XLR output, RCA input - Features: Digital sampler (12 seconds) - Number of Channels: 3 channels - Controls: Faders, EQ knobs, LED meters Thank you for viewing. Power-on and output confirmation of channels 1-3 with line cables. Phono output has not been confirmed due to lack of record player equipment. No scratchiness was observed in the EQ of each channel. Sampler function also worked. Unfortunately, the headphone output only produced intermittent sound. I haven't tested the effects send/return as I don't know how to use them. The upper right of the body is slightly bent. Please consider this as a junk item. I apologize if I missed anything. Due to the nature of the item being junk, returns are not accepted. Included accessories are the BEHRINGER genuine power adapter. Regarding the compatible power adapter, it is the Behringer MXJP2, and since most listings do not include the adapter, this item is rarely available. If you are looking for one, please consider this opportunity.
