Most electrostatic headphones are very inecient. Due to the limited voltage handling and the low sensitivity, electro-
static headphones generally do not play very loudly, especially compared to traditional dynamic headphones.
Depending on the impedance control setting the iCAN Phantom can deliver between 320V RMS (910V PP) to 640V RMS
(1820V PP).
These are very high voltage levels and may exceed the rated limit of the electrostatic headphones. Please conrm with
your electrostatic headphone manufacturer what levels are allowed and, if in any doubt, only use the high impedance
settings.
When using the iCAN Phantom, remember to keep the Gain, XBass and XSpace settings moderate. Gain is recommended
at 9dB, XSpace only at the lower settings and the same for XBass, as otherwise the stress on both amplier and
headphone may be excessive.
Under the above conditions the volume on the iCAN Phantom should be able to be advanced to maximum (using an iFi
DAC) without risk of protection circuitry engaging or damaging ANY electrostatic headphones as long as the impedance
setting is 64Ω or 96Ω.
