The D‑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‑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.
