The Radial Engineering PRO ISO stereo interface takes a high output +4dBu line level signal and converts it so that it may be connected to low-level unbalanced devices (-10dBV). Its transformer-isolated circuitry eliminates noise and hum. "The Radial Engineering PRO ISO stereo line isolator takes a high output +4dB line level signal from a mixing console and converts it so that it may be connected to low level unbalanced devices. In an effort to adapt to all of the variables, the output may be adjusted with a recessed set and forget level control. This makes it easy to interface professional audio gear with devices such as computer sound cards, iPods, or -10dB recorders. To reduce noise problems, the PRO ISO is equipped with an audio isolation transformer on each channel that helps eliminate hum and buzz caused by ground loops. Connections are straightforward: inputs are standard balanced XLR female while outputs include choice of stereo RCA, 3.5mm or standard 1/4"". All connectors and controls are protected with a book-end design and the Radial PRO ISO may be rack-mounted in the optional J-Rak (sold separately) or secured to a podium using the J-clamp. This makes the ProISO an easy-to-use solution for interfacing between pro and consumer electronics and an ideal interface for recording events. AThe balanced stereo line-level inputs with XLR connectors accept the +4db professional signal standard. ARugged XLR connectors are glass filled nylon, 100% electrically isolated, and eliminate chassis ground potential. AGround lift on outputs can eliminate hum and buzz caused by ground loops. ARecessed level control makes fine adjustments to the unbalanced outputs for optimum recordings. AUnbalanced -10 db output jacks provide quick and easy patching to any consumer audio device like stereos and laptops. ABook-end design creates a protective zone around the jacks and switches. AFull bottom pad improves electrical isolation and keeps the unit in one place. AHigh performan...
