Global EQ:
These settings on Page 2 determine if/how equalization is
applied for your outputs. This equalizer is a four-band
parametric equalizer.
Tip: These settings are especially useful when a venue, rehearsal
space, etc. has different acoustic characteristics than the room
where you originally created your presets (e.g., the venue may
sound "boomier," or a rehearsal space with soundproofing may
deaden some of the high end). This page lets you quickly apply
some additional equalization to all of your presets without
permanently saving them.
EQ On: This setting determines whether equalization is
enabled (On) or disabled (Off) for the outputs.
Level: This setting determines if/how much the outputs' audio signal level is boosted or cut. This value is
applied the level set by the Master knob.
Low Band & High Band: These settings determine what type of equalization is applied to the lowest-
frequency band (Low Band) and to the highest-frequency band (High Band): Shelf or Cut.
Low, Low Mid, High & High Mid: The three settings for each of these four frequency bands determine the
shape of the equalization:
The first setting (Hz) determines the center frequency of the low-frequency band, low-mid-frequency
band, high-frequency band, or high-mid-frequency band.
The second setting (dB) determines how much the equalizer boosts or cuts the signal at the
corresponding frequency band.
The third setting (Q) determines the width of the frequency band. The higher the setting, the wider the
band will be around the center frequency (the first setting). This setting is applied whether Low Band or
High Band is set to Shelf or Cut.
