1-3-9 EQ (Equalizer)
In general, an equalizer (EQ) is used to correct the sound output from amplifiers or speakers
to match the special character of the room, or to change the tonal character of the sound.
The sound is divided into several frequency bands, and adjustments are made to the sound by
raising or lowering the level of each band. By adjusting the sound according to the genre
(classical music being more refined, pop music more crisp, and rock music more dynamic) you
can draw out the special characteristics of the music and make your performance more
enjoyable.
2-band EQ This Effect type is an equalizer that allows equalization of the Low and
High bands. This is applied after the Insertion Effects.
3-band EQ This Effect type is an equalizer that allows equalization of the Low, Mid,
and High bands. This is applied before the Insertion Effects.
Boost 6,
Boost 12,
Boost 18
Boosts the entire band of the selected Element by +6dB, +12dB, and
+18dB respectively.
Parametric EQ (PEQ) Use this to attenuate or boost signal levels (gain) around the Frequency.
An equalizer in which all of the parameters of equalization can be adjusted.
The adjustable parameters include:
 Center Frequency
 Gain (boost/cut) of the Center Frequency
 Bandwidth (see “Q”)
Figure 58: PEQ
Frequency Determines the center frequency.
Frequencies around this point are attenuated/boosted by the Gain setting.
Gain Determines the level gain for the Frequency, or the amount the selected
frequency band is attenuated or boosted.
Q A parameter that determines the EQ bandwidth, or range of frequencies,
to be attenuated/boosted.
Consequently, this parameter determines the frequency characteristic
curve.
In case of the 3-band EQ, the Q setting is only available for the Mid band,
which is a Peaking type EQ. The EQ Shape of the High and Low band is
of the Shelving type. In case of the 2-band EQ, the Q setting is only
available when Peak/Dip is selected as the EQ type.
