Two fully outputs and line sources such as laptops and F F shielded isolation transformers galvanically isolate input and output connections, MP3/CD players. Each left and right input is wired in creating a pair of ultra-clean audio signals immune from hum and buzz caused by parallel, enabling an unused input to act as a thruput. ground loops and RF interference. OUTPUTS (Male XLR): Additional features include a 20dB pad for extra hot input signals, a merge switch to Provides separate transformer isolated, balanced mic interface with mono sound systems, and a ground lift switch for eliminating grounding level outputs for left and right signals. issues common with unbalanced equipment. -20dB PAD (Pushbutton Switch): Available with custom designed transformers, part number SC702CT, Reduces output by 20dB for use with hot input or upgrade to audiophile quality, Jensen transformers, part number SC702. signals.
