GIESELER Kompakt II TDA1541A User manual

GIESELER Kompakt DAC II
User Manual - 2023
Welcome to the club.

Introduction
Thank you for purchasing the Gieseler Kompakt II TDA1541A DAC. This is a basic style
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. 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 warm
during operation which is normal however the TDA1541A typically dissipates 700mw so
for maximum chip life it is not recommended to leave it permanently powered on. 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.

Usage
Connect the supplied external power supply to the power socket.
Connect input devices to the Optical, Coaxial & USB sockets.
Connect an amplifier to the output sockets.
Note: XLR & RCA outputs can be used simultaneously.
Power switch down turns on the device & LED shows when on & connected to power.
Right hand switch is the input source selector.
Note 1 It is normal to hear a small click when changing inputs.
Note 2 In some circumstances if you have an active USB input when using Coax or Optical
the sound may be muted.
Operating the input switch to USB & then back to coax/optical will un-mute the sound.
