The Hercules DJ Console Rmx accomplishes two feats: it works as aUSB audio card for routing 16-bit, 44kHz audio to and from your Mac orPC; and it works as a MIDI hardware interface for your DJ software. For less than $400, the Hercules DJ Console Rmx practicallypays for itself as a USB audio card. You only get four channels ofaudio coming and going from the Rmx, and the sheer quantity and varietyof high-grade audio connections is impressive. The back of the DJConsole Rmx includes two pairs of RCA and 1/4-inch outputs, a pair ofRCA inputs for each of the two channels, which are switchable betweenline and phono, and two grounding posts for older turntables. You'llalso find a pair of quarter-inch headphone and microphone inputs on thefront and face of the DJ Console Rmx. All these audio connections addup to one of the most flexible USB DJ consoles we've tested, allowingturntables, microphones, CD players, and speakers to all plug into onecentral piece of mixing hardware.
