Radial J-ISO – Stereo +4dB to -10dB Converter


The J-ISO is a stereo interface designed to take a high output +4dB line level signal from a mixing console and convert it so that it may be connected to low level unbalanced devices. In effort to adapt to all of the variables, the output may be adjusted with a recessed ‘set & 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 J-ISO is equipped with an audio isolation transformer on each channel that helps eliminate hum and buzz caused by ground loops.

Connections are straight forward: 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 J-ISO may be rack-mounted in the optional J-Rak or secured to a podium using the J-clamp. This makes the J-ISO an easy to use solution for interfacing between pro and consumer electronics and an ideal interface for recording events.
