![]() This flexibility allows the technician who is calibrating the system to hone in on specific issues. As such, each band has three values associated with it in the configuration screen. Parametric Equalizer BasicsĪ parametric equalizer is more flexible than a graphic EQ in that you have control over the center frequency and the bandwidth of each equalization band. The -3 dB points on either side of the 1 kHz peak are at 8 Hz, respectively. We can see that the signal has been boosted by 10 dB. We have applied 10 dB of boost at 1 kHz using the ARC Audio DSP Pro software. It should be noted that if there is a need for a significant amount of boost, there’s possibly a cancellation issue in the vehicle that can’t, or shouldn’t, be resolved with tuning. Properly designed 32-bit processors have enough digital headroom that significant boosts don’t cause distortion. There are myths around the maximum amount of boost you can add to a signal that was based on analog processing and noise issues. If you have a 20-band EQ, then that would be a half-octave EQ, and each adjustment would have a fixed Q-factor of 2.87.Įach band of the equalizer can add to the signal (called boosting) or remove information around a specific frequency (called cutting). For a 31-band equalizer covering the entire audio range from 20 Hz to 20 kHz, each adjustment has a Q of roughly 4.32. A 31-band EQ is often referred to as a 1/3-octave equalizer because there are three adjustments available per octave. The range of frequencies each band affects is determined by the total number of frequencies in the equalizer. Graphic Equalizer BasicsĪ graphic equalizer comprises a number of adjustments (called bands) that are set at specific frequencies. In the digital domain, there are four types of equalizers that we’ll discuss: graphic, parametric, semi-parametric and shelving. The simplest and most common equalizer would be the bass and treble tone controls built into a standard radio. What Is an Equalizer?Īn equalizer, often called an EQ as an abbreviation, is an electronic device that changes the frequency response of an audio signal. Let’s look at how the equalizer in a digital signal processor works, explain its importance, and offer some purchasing tips. Even if you’ve purchased the best speakers available and invested in having them integrated into your vehicle with the utmost precision – compensating for the acoustic characteristics of the vehicle is necessary to achieve great sound quality. Automating resonance of the low and high-cut filters produced subtle zipper noise in some cases, fixed.As we roll forward with our look at the importance of digital signal processors in car audio systems, we’ll talk about the need for proper equalization.Spectrum display did not draw properly for some users, fixed.Resonance parameter for low- and high cut filters added.This mode can also be used to find problem frequencies in a mix.įor more information, download the GQ-7 user manual: If you want to hear just the dry audio, the innovative Send Mode feature removes the dry signal from the output completely, allowing you to process the wet EQ signal separately from the input. This will speed up the work flow tremendously, reducing the need to adjust the volume knob manually in order to compare the processed and unprocessed audio. The Auto-gain compensation feature makes an educated guess of the volume difference before and after equalization, based on the current EQ settings. Especially the steep low- and high cut filters are well suited for creative purposes- their unique sound offers a great alternative to the typical sound of standard low- and high pass filters known from synthesizers. The low-cut and high-cut filters offer a variety of modes with slopes ranging from 12dB to 96 dB per octave, approaching a brick-wall response – indispensable tools for mixing and mastering.Īll filters in the GQ-7 are designed to handle modulation without artifacts, such that the EQ can be used for creative purposes too, well outside the realm of traditional EQ applications. The five EQ bands available feature adjustable gain, frequency and Q, and can be toggled between Peaking and Shelf types. ![]() The GQ-7 is suitable for a broad spectrum of tasks - whether you need an equalizer to mix instrument tracks, remove problem frequencies in your master with great precision, or get rid of the mic rumble in recordings, the GQ-7 does it all, while delivering superior results.Įditing in the GQ-7 can be performed both via knobs, as well as via the interactive graphical display with zoom controls, providing an effective and intuitive work flow. The Synapse GQ-7 rack extension is designed as a professional mixing and mastering equalizer, offering five bands with high-quality parametric and shelving EQs, plus two additional low- and high cut filters. ![]()
