This 4U rack-mountable advanced mixer from Pyle Pro has 4 channels for the ultimate mixer or DJ setup. There are a total of 8 line inputs, 3 of which can take phono or line inputs - you choose which input you want on each. Two mic inputs (one XLR/1/4" combo, one ¼") with rotary sensitivity controls and talkover switches make this mixer perfect for a larger setup. Four outputs total for maximum versatility: two master (one RCA, one balanced XLR), one record, and one for the DJ booth, so you can monitor your mix. The 5-band slider EQ gives you total control over your sound. The dual-mode, two-channel LED display shows you levels on either the master or cue output, so you'll know whether your mix is too soft, too loud, or just right. An assignable crossfader lets you chop and cut up any two channels. The ¼" jack headphone jack on the front lets you hear your mix privately before unleashing it unto the world. For extra light, plug into the included 12V BNC lamp socket. This unit is robustly constructed and takes both 110 and 220 V AC input.
