The MA4100 includes both RCA and Mini-Din (balanced) inputs. The supplied RCA connections allow you to use the MA4100 with other brands of audio gear. Our Differential RCA inputs provide a dramatic improvement in noise reduction over standard RCA input types. Our fully balanced Mini-DIN connection system features high signal voltage capability and the highest possible sound quality. A single cable for 2 channels also simplifies installation. Cables from the source unit, non-powered equalizer, or crossover go here.

Standard coaxial RCA cables utilize two connections: a center wire (signal positive) attached to the center pin of the RCA connector along with a braided outer conductor (signal negative) connected to the outer ring of the RCA connector. This design almost always allows radiated noise to enter the system, since the signal is not well protected.

Balanced Mini-Din connections use six pins and one grounding ring. Pins 1 and 2 are open connections, normally they would carry your remote turn on voltage. Pins 3/4 and 5/6 are pairs of twisted conductors for the music signal. The twisting of the inner wires rejects or eliminates radiated noise by more than 30 dB. The inner pair of wires are then protected by an outer shield connected to Pin 1. This means the music signals can be kept as far away as possible from the power and chassis ground paths of other circuitry, allowing the transmission of pure music between points while protecting it from noise generating equipment and wiring present in the vehicle. The diagram below shows the pin configuration for the Mini-Din connections.
