Input Jacks
The TUBE DRIVER includes both RCA and Mini-Din (balanced) inputs. The
supplied RCA connections allow you to use TUBE DRIVER 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
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 Cable
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 a pair 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.
