The ProCo iRack Portable Audio Player Interface is a device that allows simple and reliable connection of the stereo headphone output of audio devices such as MP3 players, Apple iPods, laptop computers and consumer-type CD and DVD players to the balanced microphone inputs of audio mixing consoles.
The iRack provides both a Stereo mini 1/8" (3.5 mm) and left/right RCA phono inputs for easy connection with standard patch cables and a stereo/mono switch to provide passive input summing to a dual mono output feed where required. The inputs may be used simultaneously, if required. If only a single source is used, the second set of inputs may be used to derive an unbalanced mono feed for recording purposes.
The outputs are isolated via audiophile-grade ProCo MBT-1 Microphone Bridging Transformers and outputs appear on an easy-to-wire screw-type barrier strip (requiring no crimp terminals) for rapid installation. The transformers offer wide bandwidth and low distortion and phase shift, and are magnetically shielded in mu-metal cans and electrostatically isolated with dual Faraday shields. The result is near-ideal rejection of common-mode signals from all sources of RFI and EMI, including radio pickup, SCR dimmers and 60 Hz hum.
The GROUND LIFT switch allows correct grounding for either AC or battery-powered sources, eliminating hum and buzz from ground loops between portable and house equipment.The iRack is built on a standard-sized single space rack panel constructed of 1/16" (1.59 mm) anodized aluminum. All functions are clearly identified by laser-engraved legends, providing an attractive and professional appearance in addition to trouble-free technical functionality.
