RADIAL ENGINEERING PRO ISO

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 ¼" 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.
