Radial ProISO Voice Range Passive Converter

4dB to -10dB converter and Isolator
The Pro-Iso is a +4dB to -10dB converter that employs a cost effective transformer that focuses the energy in the voice range. This makes the Pro-Iso a great choice for sermons, news gathering and spoken voice.

Exceptional signal handling
The passive design begins with 100% discrete components throughout. A set & forget level control lets you attenuate the input signal to prevent it from overloading the destination device. Output connections include a stereo pair of º" connectors, a set of RCAs and a mini 3.5mm (1/8") for interfacing to a mini recorder or lap-top computer. Transformer isolation helps eliminate hum and buzz caused by ground loops while eliminating 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 a CD player or other consumer 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 & forget level control on the Pro-Iso to set signal level.
