Pro-ISO | Buy Radial Engineering direct from Singapore's Authorized Distributor for warranty assurance.
The Pro-ISO +4/-10 dB Stereo Line Isolator from Radial Engineering is a stereo line isolator designed to convert a professional +4 dB line-level balanced signal to an unbalanced -10 dB consumer-level device. This enables you to take the balanced output of a mixer and feed a consumer-level recorder or audio input on a computer.
The Pro-ISO employs a transformer that focuses the energy in the voice range making it a suitable choice for sermons, news gatherings, and spoken voice.
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 stray DC currents from flowing.
Utilizing Radial's bookend construction, the Pro-ISO has 14-gauge steel construction throughout. This creates a protective zone around the connectors and controls for added durability. The steel construction also assists by shielding the transformers from outside magnetic fields.
