ifi PHANTOM Series - Bias Memory Card Slot; AC Termination Adjustment

Bias Memory Card Slot
Before using the Pro/Custom bias electrostatic headphone output port, select the bias voltage memory card according
to the table below or according to the recommendations given by the electrostatic headphone manufacturer and the
specications of your electrostatic headphone.
Bias voltage usage:
500V Sennheiser Orpheus HE-90, Monoprice Monolith Electrostatic
540V Sennheiser HE-60, King Sound KS-H2/3/4
580V Stax Pro Bias ESHP, Audeze crbn, Nectar HiveX, Muamp, VOCE
600V Koss ESP/950 & DROP Koss ESP/95X, Jade
620V HIFIMAN Shangri-La/La jr/Jade 2
640V Sennheiser HE 1, HIFIMAN Shangri-La/La jr/Jade 2, Phenomenon Libratum/Canorum
Tip: In the bias memory card holder/front cover (item 24), there are six bias voltage setting memory cards from 500VDC to 640VDC.
AC Termination Adjustment
Adjust the electrostatic headphone output mode, which can be adjusted with Electrostatic headphone power (item 2) turned on.
Tip: AC termination aects the operation of the headphone by either making the bias node that is shared between both channels high impedance, or low
impedance for audio signals. This aects a complex set of parameters, but audibly mainly aects the presentation of the XSpace Holographic Matrix System. AC
Termination ON means the bias node has low impedance. OFF is high impedance.
Tip: When a bias memory card is not inserted into the memory card slot (item5), the Pro/Custom bias ESL headphone output socket cannot be used, and PRO/FULL
modes cannot be adjusted.
