![]() For a cleaner sound from your vocal mic, filter out sounds below that frequency to remove rumble and room noise. Fundamental vocal frequencies fall around 100 Hz. Let’s look at some important frequency ranges:īass: 60 Hz to 200 Hz This low end of the spectrum includes kick drum, toms, bass guitar, and deep synth sounds. The human hearing range falls between 20 and 20 kHz and sound systems tend to deliver frequency responses somewhere close to that spectrum. Making informed EQ decisions gets easier as you learn the frequency ranges of voices and instruments and become familiar with the characteristics of key frequency bands. The JBL PRX-800 Series, for example, offers basic metering, gain staging, presets, delay, and an 8-band parametric EQ, controllable in its PRX Connect app. systems offer built-in EQs ranging from simple bass and treble controls to full graphic or parametric equalizer functions. Widening or narrowing a parametric band’s Q lets you dial in wide swaths of frequencies or ultra-precise frequency targets. A parametric equalizer is a little more complex, giving you control over three selectable attributes: boost or cut level, center frequency, and bandwidth (known as “Q”). The most common equalizers for live sound applications are graphic and parametric EQs: A graphic EQ offers the ability to boost and cut individual, fixed filters spaced evenly over the entire frequency range, usually in third-octave bands. That said, the EQ concepts presented here are universal and will apply to larger groups who are mixing their sound through an independent mixer such as a Soundcraft Signature or Ui-series mixer.ĮQ, at its simplest, increases or reduces volume levels of target frequencies in an audio signal. In these use cases, people often choose the simpler set-up provided by plugging into a self-contained, powered PA system that has built-in mixing capabilities, such as the JBL EON700 Series or PRX800 Series. In this blog we’re focusing on advice for solo or smaller musical ensembles such as singer-songwriters, duos, DJs, MCs or even someone making a presentation. system, access to its EQ controls, some reference material, and your ears. EQ is the most effective tool for tailoring your sound system and once you know the basics, EQing a portable P.A. ![]() systems offer digital signal processing that brings sound-sculpting tools right to your fingertips.
