Harbinger Pa Eq Tips For Studio Monitors

If you're looking to get the most out of your Harbinger PA system, it's important to understand how to EQ your studio monitors properly. Studio monitor calibration is the process of adjusting your monitors so they're accurate, which means tweaking the frequency response, level, and distance of your monitors so they reproduce sound as accurately as possible. This is important because it ensures that what you're hearing is accurate, and you're not inadvertently boosting or cutting certain frequencies without realizing it.

There are a few different ways to find the frequency response of your monitors. One way is to use a spectrogram, which is a visual representation of the frequency response of a sound. Another way is to use a measurement microphone and a sound level meter, which is more accurate but also more expensive. Once you know the frequency response of your monitors, you can start to EQ them to achieve a flat frequency response, where all frequencies are reproduced evenly.

Harbinger offers a range of PA speakers, from the APS15 15 Powered PA Speaker to their Compact Portable PA System, which is a full-range system ideal for venues, touring bands, and DJs. Their VARI Studio monitors provide three different voicings, making it easy to spot mixing mistakes and confirm they're fixed.

Understanding the basics of calibration

Calibration is the process of adjusting your audio system to achieve the best possible sound quality. It involves setting up each component, from speakers to subwoofers, to deliver the purest sound quality without any distortions or imbalances. This is essential to ensure that your audio system has perfect tonal accuracy and time alignment, allowing you to hear every subtle detail and experience the full range of frequencies as the creators intended.

• Room Acoustics: Every room is unique in size, shape, and furnishings. These factors impact the overall sound quality and need to be considered during calibration. A trained professional can analyze these characteristics and tailor the audio system's settings accordingly.
• Speaker Placement: The placement of your speakers is crucial for optimal sound output. For the best calibration results, speakers should be positioned as close to seated head height as possible, forming an equilateral triangle with your seating area.
• Sound Level Meter: To calibrate your sound system, you'll need a sound level meter or a smartphone app that can measure sound levels. This will help you adjust the volume of each speaker until the readings are consistent across all channels.
• Test Tone Generator: Most modern receivers have a built-in test tone generator that produces white noise through each speaker. This allows you to measure and adjust the sound levels for each speaker.
• Equalizer and Audio Settings: Your receiver's equalizer, crossover frequencies, and channel levels can be adjusted to minimize any room-induced distortions and create a balanced sound.
• Subwoofer Calibration: Calibrating your subwoofer is essential to ensure a powerful and immersive bass experience. You can calibrate it by ear or use a conversion chart to find the ideal volume setting.
• Regular Maintenance: It's important to regularly check and recalibrate your system to maintain optimal sound quality. Changes in room layout, new furniture, or different types of media can impact sound performance.
• Speaker Distance: Inputting the exact distance from each speaker to your listening position is crucial for achieving high-quality, calibrated sound. Modern receivers may ask for measurements in inches or feet, so precise measurements are essential.
• Speaker Crossover: Speaker crossover settings determine when your amplifier stops sending bass sounds to your speakers and redirects them to your subwoofer. Refer to the speaker manufacturer's specifications to set the optimal crossover frequency.
• Immersive Surround Sound: Achieving immersive surround sound involves precise speaker placement and meticulous calibration. Factory-trained professionals can help set up multi-channel audio systems to create a magical, enveloping soundscape.

Using a spectrogram to find the right frequency response

A spectrogram is a visual representation of audio that displays time, frequency, and amplitude all on one graph. It is a useful tool for finding the right frequency response when EQing a Harbinger PA for studio monitors as it can reveal audio problems by sight and help with mixing and editing sound.

To use a spectrogram to find the right frequency response, follow these steps:

• Choose a suitable spectrogram software or tool, such as iZotope RX or a signal analysis software program.
• Import your audio file into the software and select the spectrogram view or mode.
• The spectrogram will display the audio file's frequencies over time, with the vertical axis showing frequency in Hertz and the horizontal axis representing time. Amplitude is then represented by brightness or colour.
• Look for any audio problems or imbalances in frequencies, such as too much high or low end. These will appear as bright or coloured areas on the spectrogram.
• Make adjustments to your EQ settings to correct any issues and improve the overall frequency response. For example, if there is too much bass, you can reduce the low-end frequencies.
• Review the spectrogram after each adjustment to see the impact on the frequency response and make further tweaks as needed.

By using a spectrogram in this way, you can fine-tune your EQ settings and find the right frequency response for your Harbinger PA and studio monitors. This will help ensure that your audio is well-balanced and that your mixes will translate accurately to different listening setups.

Using a microphone and sound level meter

Once you have your equipment, place the microphone in front of your monitors and play a sound. The sound level meter will show you the level of the sound at different frequencies. This information will help you determine which frequencies your monitors are struggling to reproduce.

For example, if you see a lot of activity in the low-end frequencies, it means your monitors are reproducing those frequencies well. On the other hand, if you see very little activity in the high-end frequencies, it means your monitors are not reproducing those frequencies effectively.

Once you know which frequencies your monitors are struggling with, you can start adjusting the EQ to compensate. This process involves increasing or decreasing the levels of specific frequencies to achieve a flat frequency response, where all frequencies are reproduced evenly.

It is important to note that a flat frequency response is ideal, but in reality, it is rarely achieved. Most monitors have a slightly uneven frequency response, which is why EQ adjustments are necessary to achieve optimal sound quality.

By using a microphone and sound level meter, you can fine-tune your Harbinger PA studio monitors to ensure they are accurately reproducing sound across all frequencies, resulting in a more balanced and professional-sounding mix.

Equalizing your monitors

Before EQ'ing your studio monitors, it's important to understand what studio monitor calibration is and why it matters. Studio monitor calibration involves adjusting the frequency response, level, and distance of your monitors so that they reproduce sound as accurately as possible. Calibration tools, such as the BAFX SPL calibration tool, can help you with this process.

To EQ your studio monitors, you'll need to adjust the levels of different frequencies to achieve the desired sound. This can be done using the knobs and switches on the back panel of your monitors, which typically include a high-frequency filter and a low-frequency filter. Start by playing a sound and adjusting the high-frequency filter until the sound is balanced. Then, adjust the low-frequency filter until the sound is balanced. Finally, adjust the phase until the sound is clear and focused.

When EQ'ing your monitors, it's important to use a reference soundtrack, start with a flat EQ, and only boost frequencies that are already present in the mix. You should also aim for a low Q of around 2 or 3 and avoid boosting or cutting frequencies by more than 6 dB. Additionally, listening to your mix in mono can help you hear frequencies that might be masked in stereo and avoid creating phase issues.

Harbinger VARI Studio monitors provide three different voicings, allowing you to easily spot mixing mistakes and confirm that they are fixed. The NORMAL voicing offers a satisfying, full-range reproduction with rich low and high-frequency responses. The REFERENCE voicing provides an accurate reproduction with less pronounced low and high frequencies for a more honest mix check. Finally, the SMALL voicing lets you check compatibility with small speaker systems and mobile devices.

Using an equalizer plugin

If your Harbinger studio monitors don't have any back panel knobs or switches, you can use an equalizer plugin to EQ your monitors.

There are two main types of equalizers: parametric and graphic. A parametric equalizer is one that allows you to boost or cut specific frequencies. It has three main parameters: frequency, gain, and Q. The frequency parameter is the centre frequency that you want to boost or cut; the gain parameter is the amount by which you want to boost or cut the frequency; and the Q parameter is the width of the boost or cut. A higher Q will result in a narrower boost or cut, while a lower Q will be wider.

A graphic equalizer, on the other hand, allows you to boost or cut specific frequencies in a fixed manner. Unlike a parametric EQ, a graphic EQ doesn't have a Q parameter, so the width of the boost or cut is fixed. Graphic EQs usually have 31 bands, meaning they can boost or cut 31 different frequencies. Each band is typically 1/3 octave wide, which means it will boost or cut a range of frequencies around the centre frequency.

When setting up your EQ, you should always start with a flat EQ when mixing. This means that all of the frequencies are set to 0 dB—the neutral starting point from which you can make adjustments. As a general rule, you should only boost frequencies that are already present in the mix. If a frequency is not present, boosting it will not improve the sound. Conversely, you can cut frequencies that are not present in the mix without affecting the sound quality. This can be helpful if you're trying to get rid of unwanted noise or make room for other instruments.

When boosting or cutting frequencies, use a low Q, which will result in a wider boost or cut and sound more natural. Aim for a Q of around 2 or 3. Avoid boosting or cutting by more than 6 dB, as this will usually result in a noticeable change in the sound of the mix.

Listen to your mix in mono when EQing. Mono is a single channel of audio, as opposed to stereo, which is two channels. Listening in mono will help you to hear frequencies that might be masked in stereo and avoid creating phase issues, which can cause problems when the mix is played back in stereo.

Always use a reference soundtrack to equalize your studio monitors. This will give you perfect clarity of sound.
