Alesis 15 quick start EQ Equalizer, Edge, HUM Cancel

EQ (Equalizer)

This module provides you with a high-pass filter and four bands of equalization that you can use to shape the sound of your audio signal by cutting and boosting certain frequencies.

HPF (High-Pass Filter)

Turns on the high-pass filter, which reduces very low frequencies (below 80 Hz). Useful for getting rid of noise caused by air conditioners, passing cars or other low- frequency rumble (great if you’re recording at home).

Turns off the high-pass filter.

LOW

Boosts or cuts frequencies below 150 Hz in 1 dB steps from -12dB to +12dB.

Turns off the LOW EQ band.

LO MID

Boosts or cuts the 700 Hz range in 1 dB steps from -12dB to +12dB.

Turns off the LO MID EQ band.

HI MID

This band is a parametric band at 2.5kHz with a Q of 1.5.

Boosts or cuts the 2.5 kHz range in 1 dB steps from -12dB to +12dB.

Turns off the HI MID EQ band.

HIGH

Boosts or cuts all frequencies above 5 kHz in 1 dB steps from -12dB to +12dB.

Turns off the HIGH EQ band.

EDGE

This is a filtered limiter that gives your acoustic guitar a bright, edgy sound. This effect works by taking the original signal, filtering out all frequencies that fall below 2kHz, feeding that into a limiter and then mixing it back with the original, unfiltered, unlimited sound.

Increasing amounts of edge.

Turns off EDGE.

HUM CANCEL

The hum canceller eliminates unwanted low-end hum by eliminating the frequency that contains the hum (60Hz). Unlike the high-pass filter, this mode allows you to control how much noise you want to eliminate.

Increasing levels of hum elimination (60Hz harmonic notch filters).

Turns off the hum canceller.
