Product Overview

The Pro-Iso is a +4 dB to -10 dB converter that employs a cost-effective transformer that focuses the energy in the voice range. This makes the Pro-Iso a great choice for recording sermons, news gathering and spoken voice from a professional mixer to a commercial portable recorder or computer.

The passive design begins with 100% discrete components throughout for minimal noise interference. A "set-and-forget" level control lets you attenuate the input signal to prevent it from overloading the destination device, and the bookend chassis design prevents the knob from getting bumped later on. 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 lap-top computer. The ground lift switch helps eliminate hum and buzz caused by ground loops while eliminating stray DC currents from flowing.

When you need to convert balanced +4 dB outputs for a commercial device, the Pro-Iso comes to the rescue!
