J-Iso™ Specifications

The Radial J-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.
