Pro-Iso +4dB to -10dB 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.
Converts balanced line level signals to unbalanced
Stereo signal path with set & forget level control
Transformer isolated to eliminate hum & buzz
Cost effective transformers targeting voice range
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 ?" 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.
Pro-Iso Specifications
The Radial Pro-Iso is a pro to consumer signal converter. It is designed to take a +4dB balanced line level and bring this down to a -10dB unbalanced format for easy manipulation with computers, hand held recorders and other unbalanced systems. Set and forget controls allow the system tech to set levels for optimal signal transfer. The J-Iso and Pro-Iso differ with respect to the transformer and audio signal path. The J-iso is designed to deliver full bandwidth audio while the Pro-Iso is band limited for the voice range.
