Interconnect Cables



EFF-I Interconnect Cable
Analogue/Digital 75 Ohm
The dynamic influence of the skin effect is of great sonic influence as the music/video signals are nothing but variations. By means of the Equalized Frequency Flow technique (EFF) Supra takes skin effect into account. The EFF-I cable consists of two tube-shaped conductors with a wall thickness of 0.20 mm which is well below the smallest skin depth within the audio range. This makes all frequencies operate under the same conditions.

EFF-I Interconnect Cable Construction
Silver plated OFC copper 0.5 mm2/conductor. Tube-shaped flexible conductors with a center core of PE. Two conductors, individually screened, for balanced or semibalanced connection.

Application examples: Analogue interconnect or digital audio with 75 Ohm RCA interface or video interconnect.

EFF-I Interconnect Cable



DAC Digital & Analogue Interconnect Cable, AES/EBU Harmonised

A fast interconnect of extremely low capacitance. In accor-dance with our design concepts the inductance is to be low for a loudspaker cable whereas for an interconnect the capacitance is to be low. Supra DAC is insulated with PE foam skin which exhibits only 45 pF/m. It is screened with our very efficient and strong semiconductive nylon ribbon. Supra DAC is also designed for digital audio and is harmonised with the AES/EBU standard. (Square wave 60 MHz, impedance 110 Ohms, balanced.)

The very high frequency properties of Supra DAC are outstandingly good, owing to its high velocity factor. More clean transients and thus improved space dimension comes with the high velocity.

The velocity factor of Supra DAC is as high as 78% of the speed of light, owing to the low dielectricity of the gas blown foam skin insulation. With PTFE/Teflon it would have been only 71%.

The velocity factor can be calculated with the simplified formula:
where K is the dielectricity factor of the insulation material.
