5 - EQ SECTION
The mixer's EQ section allows very differentiated shaping of the incoming audio signal within miscel-
laneous frequency bands. Turning one of the EQ level controls to the right enhances/amplifies the cor-
responding frequency range while turning it to the left lowers/attenuates the signal of that specific
frequency band. Before you begin to alter the sound, all EQ controls should be set to their neutral po-
sition, i.e. their marker points straight up (locked in place). Try not to 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 the natural reproduction as an orientation mark and rely on your musically
trained ear. The moderate use of the MID control is the best remedy to avoid acoustical feedback. Es-
pecially in this frequency range you should try to avoid excessive enhancement. Lowering the level
more or less in this band will provide you with high amplification rates without feedback. Use the LO
control according to your pleasing, to add more "punch" to the sound of a kick drum or "body" to the
vocals. Use the HI control in the same way to provide cymbals and the human voice with more treble
and a more transparent sound.
The MID control is active in a comparably wide frequency band around 2.4 kHz. With most micro-
phones this is the critical range, where a slight attenuation offers excellent results.
6 - FX
The FX control allows adjusting individual amounts of the input signals to be routed to the integrated
FX 1 and the FX 2 effects units. The signal path is split post volume fader – post fader – so that the
fader setting also influences the amount of the signal that is fed to the FX units. Using the FX controls
lets you easily assign an effect for groups of musical instruments or vocals. To determine the desired
intensity of each effect, you should start with the control set at the center and make individual adjust-
ments from there on. Please monitor the PK LEDs in the FX 1/2 channels. The indicator should only
light briefly at the occurrence of high program peaks. If the indicator is constantly lit, you should lower
the send levels of those channels where the program peaks occur. For further information, please read
the paragraphs about the FX 1/2 units.
7 - AUX
The AUX control is primarily meant for establishing a independent monitor mix. The AUX mix is availa-
ble as output channel at the DIGITAL AUDIO INTERFACE. The AUX routing dialog in the menu allows
determining whether the signals are split pre or post fader, or using the AUX as FX 2, see page 25 for
details. The selected mode is indicated by LEDs, see page 15.
8 - MON
The MON control is primarily meant for establishing a independent monitor mix. The signal routing is
always PRE FADER.
9 - PAN
This control determines the position of the connected sound source within the stereo image. When
this control is set at its center position, the audio signal is fed with equal levels to the L and R master
busses. The PAN control section is designed to maintain the essential sound pressure level, no matter
at what position within the stereo image the PAN control is set to.
