The DIGI-COUPLER 75 Ohm has been specially designed bearing the highest possible transmission quality of 75 Ohm impedance level SPDIF consumer format digital audio in mind, and is aimed at the critical audiophile as well as the professional.
The DIGI-COUPLER 75 Ohm’s special design covers all aspects required for a flawless and reliable transmission of SPDIF digital audio at short range as well as across large studio distances and allows for notable improvements in your audio quality.
The cable’s strict HF design likewise benefits the transport of Video and HF signals well into the GigaHertz range.
The DIGI-COUPLER 75 Ohm features a very low signal attenuation per unit length. As an example: At 100 MHz the attenuation is a mere 0.11 dB/m. (For more data see HF Performance Graphs in the sidebar).Low signal attenuation (i.e. low signal loss) is especially important when long cable runs are used (e.g. in professional / studio applications).To maintain optimum signal quality, a maximum signal to noise ratio at the signal receiving side is required. The signal therefore needs to undergo as little as possible attenuation during transport. This of course equally applies to digital audio as to video and HF signals.A low signal attenuation also positively adds to immunity against external noise, though latter starts with a good shielding:
The DIGI-COUPLER 75 Ohm is a so-called “Superscreened” or “Low Transfer Impedance type” cable.
To maximize performance in keeping the signal in and noise (RFI and EMI) out, the highest possible shielding factor is required. Without making compromises, The DIGI-COUPLER 75 Ohm’s design therefore features a so-called “triaxial construction” which makes use of multiple highest quality shields.
(Triaxial construction: essentially a coaxial cable surrounded by an extra separately insulated shield).
In The DIGI-COUPLER 75 Ohm not less than 3 dense braided shields, 3 foil shields and a Linear Structured Carbon ® (LSC) saturated outer layer are used, which combined shielding factor results into an ultra high screening attenuation and an ultra low transfer impedance; This allowing the cable to carry the designation “Superscreened”.
The DIGI-COUPLER 75 Ohm’s supreme immunity against radio frequency and electromagnetic interference allows trouble-free use of large lengths. Multiple lengths can be run in parallel without risk of mutual interference, even with other cabling (e.g. in cable conduits).
The DIGI-COUPLER 75 Ohm provides the cleanest possible signal transport in all 75 Ohm impedance level applications and is the ultimate choice for the critical audiophile, videophile and professional.
