GIESELER Kompakt DAC
Wolfson Chipset
User Manual - Version 1
Welcome to the club.

Introduction
Thank you for purchasing the Gieseler Kompakt DAC. This is a new base model but aimed
at maximum sound fidelity, and is a quality Australian made product that includes a full
two year parts and labor warranty. All parts are sourced from quality suppliers such as
Element14 and RS Components. Maximum sound quality is obtained via the USB input of
the DAC, however, the S/PDIF section is also very good and has been upgraded over
previous models. Microsoft Windows based music servers will require an additional driver
to be installed for use, however this is not necessary for Mac and Linux systems. The unit
runs remains fairly cool during operation, but warms during extended use; this is expected
and poses no problems. Upon power up of the device, automatic muting will ensue for up
to thirty seconds to ensure a silent start. Sound quality will optimize after one hundred
hours of use as electronic components are 'run in'. Please note it is normal to hear a click
through your speaker when switching between unconnected inputs.
