DESCRIPTION
When using the Impacto essential, a Digital-to-Analogue Converter
with an integrated headphone amplifier, you can play highresolution audio files with up to 384 kHz / 32 bits (PCM) or up to
5.6 MHz (DSD). The powerful Impacto essential is compatible with
all low impedance and high impedance headphones to which a
mini (3.5 mm) jack plug with a shaft diameter of 7.5 mm can be
connected to the ear cups on both sides1). In this way, the headphones are provided with a digital interface so that the user does
not need a jack socket on mobile devices anymore. Due to three
different connecting cables, the Impacto essential can be used with
various devices: smartphones*, tablets* or notebooks / PC /
MacBook with USB output. The Impacto essential works with all
devices that have a USB host function or USB OTG (On-The-Go).
With buttons, the user can skip tracks and control play/pause as
well as the volume of the music playback.
Via the Hi-Res LED, the user can check if Hi-Res audio files are
transmitted and played back.
