The D/DS/RCX-J2 is a complete unbalanced audio input panel assembly. The front panel features two phono jacks intended for mono or stereo consumer level sources. LEFT and RIGHT are combined and balanced through audio transformers configured to reject induced hum. A balanced line-level output is provided on the rear-panel terminal block for connection to 10 k? or higher input impedance line level module or equipment inputs. The back of the D/DS/RCX-J2 is finished with a metal enclosure clearly labeled for easy installation. The D/DS/RCX-J2 fits directly into back boxes, available from RDL to fit cabinets or US or international walls (RDL WB-1U). They may be mounted directly into cabinets or most standard US single gang electrical boxes.
