Special features

The Float QA is the modern successor of the legendary Float electrostat and has been manufactured since 2012 in Manufactured by Quad -Musik in Gehring, located west of Koblenz. It was developed in collaboration with Jürgen Jecklin . Wearing comfort: ??? The "head speaker" rests loosely on the "average head" and requires a calm posture to avoid falling down. With "above-average head shapes or sizes" the ears are pinched; an adaptation to different head sizes or shapes is not given because of the rigid design. This may be one reason for the controversial and sometimes quite subjective opinions. The main competitors with the same converter principle are the models from Stax .

Principle: electrostatic push-pull converter with constant charge
Coupling to the ear: completely open (head loudspeaker design)
Nominal impedance: 4 to 16 ohms
Rated load capacity:
practically zero, since with an average head diameter, the transducers are placed freely floating in front of the ears due to the headband shape of the headphones.

HV cascade on main board
Mains voltage: 220 V / 110 V optional
Signal connection: Screw terminals
Switch for switching headphones/speakers?
Overload protection:

A special power supply is required to operate the headphones. The supply device is connected both to the loudspeaker output of the amplifier and to the mains voltage in order to generate the bias voltage for the electrostats from it by means of a diode cascade circuit. The sound signal is modulated in the power supply to the high voltage necessary for the operation of the headphones. The power supply unit is equipped with a switched loudspeaker output which makes it possible to switch the input signal through to connected loudspeakers. In this switching state, the headphones are then deactivated.
