    6.3mm TRS x 2 (iFi SEC balanced system) Note: The iFi SEC (Single-Ended Compatible) balanced connection uses one 6.3mm Jack for L-/R- (left jack) and the other for L+/R+ (right jack) with both sleeves being Ground (GND). This makes it directly compatible with standard non-balanced headphones.

    6d. 3.5mm (Balanced, TRRS standard) 3.5mm TRRS (with built-in iEMatch® – output matched to high-sensitivity headphones). Holographic for Headphones® / Holographic for Loudspeakers® Systems There are two separate Analogue Signal Processing (ASP) matrix circuits that switch automatically between headphone and loudspeaker use.
  • Page 9 Tip: Holographic for Headphones is not based on a standard cross-feed system, as found in some High-End headphone ampli ers. Many so called ‘3D systems’ are usually DSP based that arti cially e ect the sound and add unwanted reverb in order to simulate a ‘spacious‘...

    Stereophonic sound) and corrected by EMI in early ‘Stereosonic’ recordings. However, the original Stereosonic circuit tended to result in a narrower soundstage than if recorded straight and often overcompensated distortion of the soundstage perspective. iFi’s Holographic systems avoid this and instead, allow an expansion of the width of the sound stage.

    20V is equal to 100W with a 4 ohm loudspeaker. These levels are very high and can damage many headphones and/or drive most ampli ers (if used as a line-stage) into very hard clipping. Damage to headphones and/or loudspeakers may result from excessively high volume settings.

  • Page 13 14,000mW (14 VA) is possible in Balanced operation. The ampli er audio circuit is a development of iFi’s revolutionary ‘TubeState’ design. It is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-bu ered bipolar class A Power stage (with Class AB for low impedance headphones at very high levels).
  • Page 14 If enabled, the Holographic matrix fundamentally re-shapes the transfer function of the actual amplifying circuit to do its job. So again, the delity of the signal is as if the Holographic matrix was designed integral to the circuit. This is a highly-unusual design, as normally signal processing functions add extra circuits to the main ampli cation circuit.
