Supra DAC-XLR digital balanced interconnect
DAC-XLR is a professional 110 Ohm interconnect cable for XLR interfaced digital audio signals according to the AES/EBU standard. The cable include our patented Supra Swift XLR connectors. Provides for balanced signal transmission a function where positive signal is inverted to form the negative on pin 3. By subtraction will any signal component present only in the signal path 2 or 3 be cancelled out. Any malignant noise that succeeds in entering the cable, will not infect signal paths symmetrically and will therefore not survive the subtraction. A good cable with efficient shielding and correct impedance will together with the balanced transmission standard preserve signal integrity also for cables lengths in studios and on-stage at a very high level. Also some high-end hifi brands utilize balanced digital and analogue transmissions. The second very important feature with balanced transmission is that the shield and earth lead level unequal earth potentials between devices without compromising the signal.
– Application example: AES/EBU; Professional digital audio signals, and high-end hifi equipment, e.g. between CD-drive and DAC.
For digital applications it is always important with the standardized characteristic impedance. The characteristic impedance of source, cable and receiver must match the transmission standard in order to avoid digital jitter. Unfortuneatly that is not the case with some of our competitors. We att Supra always design according to the standard and also with tightest possible tolerences.
