Pro Co Sound IT1 Isolation Transformer Unit, 20Hz to 20kHz Frequency Response, >680Ohms Input Impedance, <120Ohms Output Impedance

How does the Pro Co Sound Trade Tools IT1 Isolation Transformer Unit stand out? This high-quality, durable unit is an innovative solution for complex interface problems that require the superior electrical isolation only a transformer can deliver. It's designed to minimize interference from SCR lighting dimmers, radio transmitters, and 60Hz AC power wiring, offering a common-mode voltage range that is more forgiving of improper connections or fault conditions than any electronically balanced or "differential" transformerless circuit.

This advanced IT1 Isolation Transformer Unit is essential for safeguarding portable sound reinforcement systems and installations. It's a reliable tool for sound system technicians, helping to break ground loops between equipment connected with unbalanced lines. For instance, it can float the unbalanced output of a mixer that must drive long cables connected to power amplifier inputs.

Musicians will find it a valuable asset as a line level direct box for connecting line-level sound modules, samplers, and similar devices to live or recording mixers. It provides a floating output without the voltage step-down of a high to-low impedance conversion. For broadcast and ENG professionals, it's a handy unit for deriving a remote feed from a press conference or meeting room public address system.

The unit features male and female XLR-type connectors in parallel with two 3-conductor 1/4" (6.3mm) phone jacks for LINE IN/OUT, offering nearly universal loop-through capability. Parallel jack and male XLR connectors deliver the ISO OUT to balanced or unbalanced loads. The Pro Co LOT-P transformer enables it to provide a floating, low-impedance output with wide, flat frequency response, ultra-low distortion, and no ringing or overshoot to degrade transient response.

The GND/LIFT switch ensures isolation and buzz-free operation in virtually any environment. Its "Uni-box" construction enclosure is crafted from extruded aluminum side channels and 16-gauge steel top, bottom, and end plates, designed to protect switches and connectors from accidental damage. The use of steel also provides excellent magnetic shielding for the transformer from 60Hz AC hum fields. Top-quality connectors and switches provide trouble-free service even in demanding situations such as remote broadcast and recording operations.

In summary, the Pro Co Sound Trade Tools IT1 Isolation Transformer Unit is a high-quality, reliable, and advanced solution for professional audio and video applications.
