Operating Instructions
Thank you for deciding to purchase the Miditech Guitarface, we are certain you will be delighted
with its performance and advanced features. Guitarface enables you to easily digitize all your
analog sound sources from any LINE level devices, e.g. music cassette decks or CD players, etc.
With its implemented HI-Z instrument preamp you can easily digitize instruments like electric
guitars and basses. At last the integrated MIC preamp offers you the possibility to make microphone
recordings. In addition to this Guitarface gives you a switchable phantom power for use with
condenser microphones. Please read the instructions to use this phantom power carefully! If you
use it in the wrong way, it may cause damage to your speaker system! Miditech doesn't take any
responsibilty for damage caused by improper use!
Not only does Guitarface offer a simple solution to digitizing analogue sounds, it also gives you the
very best HiFi audio quality. The included recording software Magix "Samplitude SE" offers you
the capability to edit previously digitized music or speech. The software “IK Multimedia Amplitube
2 Duo” gives guitarists some perfect simulated American guitar amps for use as standalone
application or as a VST instrument. The operating instructions will give you some guidance on how
to install and operate your Guitarface functions, also check the section on how to use the free
bundled companion programs - "Magix Samplitude SE" and the amp-simulation from “IK
Multimedia Amplitube 2 Duo”.
