The D/S-CIJ3 is the ideal choice in installations requiring the passive mixing of two unbalanced line level audio sources to feed a mono balanced (or unbalanced) audio line.

The D/S-CIJ3 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 mono or stereo consumer level sources. An input signal may be connected to either the phono jacks or to the mini-jack. The left and right signal inputs are combined and balanced through audio transformers configured to reject induced hum. A mono line-level output is provided on the rear-panel detachable terminal block for connection to a 10 kΩ or higher input impedance line-level module or equipment input.
