The two inputs are identical apart from the fact that the controls are laid out as a
mirror of each other.
Immediately adjacent to the input connectors are the mic input gain controls.
Correct gain adjustment for your microphone is essential to ensure good signal
control throughout your system. Generally speaking, dynamic microphones will
require more gain that condenser microphones.
The 48V Phantom Power button will allow you to use high-quality condenser
mics with Zone 8. If you are using a condenser mic, engage Phantom Power for
your mic to function.
The next three controls are for setting a basic equalization for your mic input.
They are independent of any equalization in WebApp. These are useful for
tailoring your sound to a particular voice/microphone combination. Use the
High frequency control for increasing or decreasing sibilance, which can help
with intelligibility. The mid-range controls allow you to choose the frequency
around which you can boost or cut, between 200Hz and 5kHz. The lower mid
frequencies will affect warmth and muddy sounding voices, the middle range will
help to stop ‘boxiness’, and the higher frequencies will assist with intelligibility or
harshness. Experiment to find out what suits your requirement.
