The Pro Co iGate Audio Gateway is a device that provides simple and reliable connection of three different audio sources to the balanced microphone inputs of audio mixing consoles. It serves as a mic input, a direct box and an MP3 player interface all together in a conveniently packaged single rack-space unit. The iGate provides a pass-through input for a balanced microphone, inputs for the stereo headphone output of audio devices such as MP3 players, Apple iPods, laptop computers and consumer-type CD and DVD players, and an input for unbalanced "instrument" signal sources.
MIC IN input is wired directly to MIC OUT on the rear panel for a convenient microphone pass-through. The INSTRUMENT input accepts unbalanced instrument or other signal sources and, through the use of the Pro Co DBT-P direct box transformer, provides a floating transformer-balanced output through the INSTRUMENT OUT on the rear panel. The iGate provides both a stereo mini COMPUTER/iPOD input and left/right RCA phono LINE LEVEL INPUT inputs for easy connection of MP3 or computer audio outputs with standard patch cables. A STEREO/MONO switch provides passive input summing to a dual mono output feed where required. The inputs may be used simultaneously. If only a single source is used, the second set of inputs may be used to derive an unbalanced mono feed for recording purposes.
All outputs (except MIC OUT) are transformer-isolated via the Pro Co audiophile-grade transformers. The transformers offer wide bandwidth, low distortion and phase shift. They 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 GND/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 GND/LIFT switch affects the COMPUTER/iPOD and LINE LEVEL IN L/R inputs only
The iGate's rugged 16-gauge steel and aluminum "Uni-box" construction enclosure is finished in a durable black texture powder coat finish with black anodized aluminum side channels. All functions are clearly identified by laser-engraved legends, providing an attractive and professional appearance in addition to trouble-free technical functionality. The iGate can be mounted in any standard 19" (482.6mm) rack. Top quality connectors and switches provide trouble-free service even in abusive situations such as remote broadcast and recording operations.
