Cut for a Cleaner Mix
For example: cymbals have a lot of energy in the mid and low frequency ranges that you don't really perceive as musical sound, but which can interfere with the clarity of other instruments in these ranges. You can basically turn the low EQ on cymbal channels all the way down without changing the way they sound in the mix. You'll hear the difference, however, in the way the mix sounds more "spacious, " and instruments in the lower ranges will have better definition. Surprisingly enough, piano also has an incredibly powerful low end that can benefit from a bit of low-frequency roll-off to let other instruments-- notably drums and bass--do their jobs more effectively. Naturally you won't want to do this if the piano is playing solo. The reverse applies to kick drums and bass guitars: you can often roll off the high end to create more space in the mix without compromising the character of the instruments. You'll have to use your ears, though, because each instrument is different and sometimes you'll want the "snap" of a bass guitar, for example, to come through.

Fundamental: The frequency that determines the basic musical pitch. Harmonics: Multiples of the fundamental frequency that play a role in determining the timbre of the instrument.
Some Frequency Facts The lowest and highest frequencies than can be heard by the human ear are generally considered to be around 20 Hz and 20, 000 Hz, respectively. Average conversation occurs in the range from about 300 Hz to about 3, 000 Hz. The frequency of a standard pitchfork used to tune guitars and other instruments is 440 Hz (this corresponds to the "A3" key on a piano tuned to concert pitch). Double this frequency to 880 Hz and you have a pitch one octave higher (i. e. The amount of time shift is controlled, or "modulated", by an LFO (Low-frequency Oscillator). For phasing effects the shift is very small. The phase difference between the modulated and direct signals causes cancellation at some frequencies and reinforces the signal at others and this causes the shimmering sound we hear.

The following applies to both the MG124CX and MG124C. In cases where different features need to be described for each model, the MG124CX feature will be described first, followed by the MG124C feature in brackets: MG124CX (MG124C).
Channel Control Section
1 MIC Input Jacks (CHs 1 to 4, 5/6, 7/8)
Channels 1 to 4 (Monaural) Channels 5/6 and 7/8 (Stereo) Channels 9/10 and 11/12 (Stereo)
These are balanced XLR-type microphone input jacks (1:Ground; 2:Hot; 3:Cold).
2 LINE Input Jacks (CHs 1 to 4)
These are balanced TRS phone-jack line inputs (T:Hot; R:Cold; S:Ground). You can connect either balanced or unbalanced phone plugs to these jacks.

Where an input channel provides both a MIC input jack and a LINE input jack, or a LINE input jack and an RCA pin jack, you can use either jack but not both at the same time. Please connect to only one jack on each channel.
5 INSERT Jacks (CHs 1 to 4)
Each of these jacks provides an insert point between the equalizer and fader of the corresponding input channel (CHs 1 to 4). The INSERT jacks can be used to independently connect devices such as graphic equalizers, compressors, or noise filters into the corresponding channels. These are TRS (tip, ring, sleeve) phone jacks that carry both the send and return signal (tip = send/out; ring = return/in; sleeve = ground).
