M-480: 4 Band Advanced Parametric EQ

This is not just any EQ, it is a set of expanded frequency shaping tools for every input channel and output bus. The M-480 provides EQ with power and flexibility far beyond the norm. The overview display of the input channel EQ shows you the interaction between a dedicated High Pass FIlter and 4 configurable bands of EQ. You can use this powerful EQ to correct frequency problems in your source, or for special effects.

Often your output busses also need EQ adjustments to improve the sound of monitor cabinets or other output speakers. Every output bus on the M-480 also has this same advanced 4 band EQ.

Each of the 4 bands in the EQ has multiple modes to select from. The 2 outer bands have 6 different modes or frequency curves while the 2 mid bands have 3 different modes. You can configure each of the 4 bands independently and then use them all together to solve problems that are beyond what a typical EQ can manage.

Peak Filter Controls a range of frequencies. The common Parametric EQ with adjustable Q, Center Frequency, and Gain. Used to balance the tone of a sound, typically removing unwanted resonance or make up for the imperfect frequency response of a microphone.
Band Pass Filter (Special Peak Filter) Allows only a narrow band of audio frequencies to sound. Most often used for special effect. Creates "lo-fi" telephone or megaphone sound.
Notch Filter (Special Peak Filter) Removes a problem in a very narrow frequency range. Commonly used to avoid feedback at a specific frequency or reduce 60 cycle hum.
Low Shelf Filter Boosts or Removes audio below a chosen frequency by the amount set with Gain. Typically used as "Bass" control. Easy to use.
High Pass Filter 6dB Removes audio below a chosen frequency, removing 6db more for every octave as the frequency gets lower. Reduces stage “rumble” and muddiness.
High Pass Filter 12dB Removes audio below a chosen frequency, removing 12db more for every octave as the frequency gets lower. More dramatic effect than 6dB version. A resonant peak can also be added around the cutoff frequency. Reduces stage “rumble” and microphone voice “pops”.
Hi Shelf Filter Boosts or Removes audio above a chosen frequency by the amount set with Gain. Typically used as "Treble" control. Easy to use.
Low Pass Filter 6dB Removes audio above a chosen frequency, removing 6db more for every octave as the frequency gets higher. Reduces “hiss”, or like a “Tone” control found on a guitar.
Low Pass Filter 12dB Removes all audio above a chosen frequency, removing 12db more for every octave as the frequency gets higher. More dramatic effect than 6dB version. A resonant peak can also be added around the cutoff frequency. Remove "hiss", reduce "bleed" of cymbals in kick or floor tom mic.
