The ProISO 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 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 ProISO 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 ProISO may be rack-mounted in the optional J-Rak 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.

Exceptional signal handling

The passive design begins with 100% discrete components throughout. A set and forget level control lets you attenuate the input signal to prevent it from overloading the destination device. Output connections include a stereo pair of 1/4" connectors, a set of RCAs and a mini 3.5mm (1/8") for interfacing to a mini recorder or laptop computer. Transformer isolation helps eliminate hum and buzz caused by ground loops while eliminating… read more stray DC currents from flowing.

Using the Pro-Iso to record a performance

Often, the available output on a professional console is balanced +4dB. This makes it difficult to feed a portable recorder. The Pro-Iso comes to the rescue with a simple interface and all of the connectivity you need.

Using the Pro-Iso to convert a balanced signal

The Pro-Iso makes it easy to convert the balanced line level output from a preamp to any -10dB consumer audio device. Transformer isolation further benefits by eliminating hum and buzz caused by ground loops.

Using the Pro-Iso to feed a computer

Computers are noisy at the best of times! The Radial Pro-Iso's effective transformers help eliminate buzz and hum while delivering exceptional audio. Adjust the set and forget level control on the Pro-Iso to set signal level.
