25Why are high supply voltages essential ?A headphone doesn't really require high power, but from the equation P = U2 / R we can see that thesquare of the supply voltage determines the power into a given load resistance. The higher theheadphone's impedance, the more voltage will be needed to achieve high listening levels. But this dealswith the achievable loudness to a limited extent only: Technically spoken, music lives on fast transientswhich put high demands on signal processing. And thus a fast transient can easily push an averageamplifier with +/-15 volts supply to its limits (90 % of all headphone amps in the market are operated withthese or even lower supply voltages). Due to the high supply voltage and the balanced operation mode ofHPA US 4+ you will benefit from nearly 4 times more output voltage swing capability compared to singleended amps with “standard” supply voltage.Why does a relay make sense when switching power ?Amplifiers generate unwanted output signals when applying or removing power, which can damage theconnected headphones. The relay breaks the connection between amplifier and headphone and thusprotects the latter until electrical conditions have stabilized.DISPOSALDisposal of Old Electrical & Electronic Equipment - WEEE Regulation(Applicable in the European Union and other European countries with separate collection systems)This symbol on the product or on its packaging indicates that this product shall not betreated as household waste.
