The black DB-CIJ3D Consumer Stereo Input Jack from RDL is a complete unbalanced line-level audio input module. The front panel features two gold plated phono jacks and a single stereo mini-jack, intended for stereo consumer level sources. An input signal may be connected to either the phono jacks or to the mini-jack. The inputs are balanced through audio transformers configured to reject induced hum. A stereo line-level output is provided on the rear-panel detachable terminal block for connection to 10kΩ or higher input impedance line-level module or equipment inputs. It is used in installations requiring stereo unbalanced line level audio sources to feed stereo balanced (or unbalanced) audio lines.
