Note on how to set the input level:
1.Set the gain control and the corresponding channel fader to their minimum setting.
2.Connect the desired sound source (microphone, musical instrument, ...) to the corresponding MIC or LINE input.
3.Play the sound source at its highest volume setting; respectively, sing or speak as loud as possible directly into the microphone.
4.While doing so, adjust the input level using the gain control, so that during the loudest passages the PEAK LED is just not lit, but the
This is the basic channel setting, leaving you with at least 8dB of headroom. Which me- ans, you have at least a range of 8dB before signal clipping. In case you intend to make further adjustments to the channel’s EQ setting, you should perform steps 3. and
4.again afterwards, since changes in the sound shaping section also influence the channel’s overall level.
5.EQ SECTION
The mixer’s EQ section allows very differentiated shaping of the incoming audio signal within different frequency bands. Turning an EQ level control to the right enhances / amplifies the corresponding frequency range while turning it to the left lowers / attenuates the signal of that specific frequency band. Before altering to the sound, all EQ controls should be set to their neutral position; i.e. their markers point straight up (detent position). If possible, do not set the EQ controls to extreme positions. Usually, minor changes are totally sufficient and produce the best results in the overall sound. You should use a natural sounding reproduction as an orientation mark and rely on your musically trained ear, which still is one of the best instruments for judging the sound quality. Try to avoid excessive enhancement of the MID band. The moderate use of the MID control is the best remedy to avoid acoustical feedback. Lowering the frequency
band’s level more or less will provide you with high amplification rates wi- thout feedback. Set the
