Parametric equalizers differ from graphic equalizers in their ability to adjust specific frequencies with more precision. Parametric EQs allow users to control the center frequency, bandwidth (Q factor), and gain of each band independently, giving them more flexibility in shaping the sound. On the other hand, graphic EQs have fixed frequency bands with predetermined bandwidths and gains, limiting the specificity of adjustments that can be made.
The purpose of a high-pass filter on an EQ is to attenuate frequencies below a certain cutoff point, allowing higher frequencies to pass through unaffected. This filter is commonly used to remove unwanted low-frequency rumble or noise from audio signals. By cutting off frequencies below the set point, the high-pass filter helps clean up the audio signal and prevent muddiness in the mix.
With the Backert preamp in the system, I then returned to using the AGD GaNFET amps. While the difference between the tube amps and the AGD amp was relatively small in my original reference system. before the addition of the Acora speakers, Synergistic Pink fuses, PowerCell8 SX, Auva footer, and the Backert preamp, each of these additional components increased the resolution of the system. Together, with the fast speed and high resolution of the AGD amp, the music crossed the line, becoming too analytical and almost piercing in the treble. This is not to fault the amp. I simply have to back off the resolution by removing some footers, changing a fuse, or even rolling tubes in the Backert preamp. That will be my personal adventure in the coming weeks. I'm sure it is doable and there is no need to take you down that trail in this review. That's the fun of fine-tuning that comes when you're this close to perfection.

Overall, the tonal balance was quite even with the bass being even stronger than the Acora or my Kharma speakers, if not quite as resolved as the Acora. The tone of the LCH subwoofers I have used with the Acora and the Kharma speakers was a bit more palpable than the Linkwitz subs. If you are a serious bass-head you may want to consider adding subwoofers or possibly tone controls but I think most people will be very happy with the Linkwitz in standard configuration. Your listening room will likely be smaller than the open floor plan of my home which soaks up a lot of bass energy.

Coinciding with the summer solstice, Fête de la Musique (World Music Day) is a day for musicians and music enthusiasts to celebrate and enjoy the music! Since music is a 'common language' globally, World Music Day seeks to strengthen musical diversity and bring together Earth's music community for a day of festivities. According to Wiki, "The Fête de la Musique, also known in English as Music Day, Make Music Day, or World Music Day, is an annual music celebration that takes place on 21 June"....

While a graphic equalizer can adjust the overall frequency response of a mix, it may not be the most effective tool for shaping the frequency response of individual instruments. Graphic EQs typically have fixed frequency bands that may not align perfectly with the specific frequencies of each instrument. For more precise adjustments on individual instruments, a parametric EQ with adjustable frequency, bandwidth, and gain controls would be more suitable.
A shelving EQ differs from a peaking EQ in terms of how it boosts or cuts frequencies. A shelving EQ applies a constant boost or cut to all frequencies above or below a specified cutoff point, creating a shelf-like effect on the frequency spectrum. In contrast, a peaking EQ allows users to boost or cut a specific range of frequencies centered around the selected frequency, creating a peak or dip in the frequency response curve.
The difference between a hardware EQ and a software EQ lies in the flexibility and control they offer. Hardware EQs are physical units with fixed frequency bands and controls, limiting the adjustability of settings. Software EQs, on the other hand, provide more flexibility with adjustable parameters, presets, and visual interfaces for precise adjustments. Software EQs also offer the convenience of being integrated into digital audio workstations for seamless workflow.
The Q factor of a band on an EQ affects the width of the frequency range being adjusted. A higher Q factor results in a narrower bandwidth, allowing for more precise adjustments to a specific frequency range. Conversely, a lower Q factor widens the bandwidth, affecting a broader range of frequencies around the center frequency. Adjusting the Q factor can help shape the character and tonal balance of the audio signal in a more targeted manner.
An EQ can be used to correct room acoustics issues such as standing waves or resonances to some extent. By adjusting the frequency response of the audio signal, an EQ can help mitigate the effects of room modes and resonances that cause peaks or dips in certain frequencies. However, while EQ can improve the overall sound in a room, it may not completely eliminate all acoustics issues, and additional acoustic treatment may be necessary for more significant improvements.
One of the advantages of using Dante or AVB in sound reinforcement is the ability to transmit high-quality audio signals over Ethernet networks. This digital audio networking technology allows for low latency, high channel counts, and flexible routing options, making it ideal for live sound applications. Dante and AVB also offer scalability, allowing for easy expansion of audio systems without the need for additional cabling. Additionally, these protocols provide improved synchronization and clocking capabilities, ensuring that audio signals are delivered accurately and reliably. Overall, the use of Dante or AVB in sound reinforcement systems can result in enhanced audio quality, increased flexibility, and simplified setup and configuration processes.
Modular sound reinforcement systems offer a multitude of benefits for audio professionals and event organizers. These systems provide flexibility in terms of scalability, allowing users to easily expand or reduce the setup based on the size and requirements of the venue. Additionally, modular systems offer versatility by enabling users to mix and match different components such as speakers, amplifiers, and processors to create a customized sound solution. This flexibility also extends to transportation and storage, as modular systems are typically more compact and easier to transport than traditional setups. Furthermore, modular systems are designed for easy setup and teardown, saving time and effort during events. Overall, the use of modular sound reinforcement systems can enhance the overall audio quality, efficiency, and convenience of any live sound production.
A delay processor in a sound reinforcement system plays a crucial role in adjusting the timing of audio signals to ensure proper synchronization and alignment within a venue. By introducing a controlled delay to specific audio channels, the processor can compensate for differences in distance between speakers and listeners, as well as address issues related to phase cancellation and comb filtering. This results in a more coherent and intelligible sound experience for the audience, enhancing overall clarity and fidelity. Additionally, delay processors can be used to create special effects, such as simulating larger acoustic spaces or achieving specific artistic intentions in live performances. Overall, the precise manipulation of timing provided by a delay processor is essential for optimizing the sonic quality and impact of a sound reinforcement system.
Ensuring RF coordination in wireless systems involves carefully managing the allocation of frequencies to different devices to prevent interference and optimize performance. This process includes utilizing spectrum analyzers, frequency coordination software, and RF filters to identify available frequencies and assign them to transmitters and receivers. By conducting site surveys, monitoring signal strength, and adjusting antenna placement, engineers can mitigate issues such as co-channel interference, adjacent channel interference, and intermodulation distortion. Additionally, implementing techniques like frequency hopping, time division multiple access (TDMA), and dynamic frequency selection (DFS) can further enhance RF coordination in complex wireless environments. Overall, a comprehensive approach to RF coordination is essential for maintaining reliable communication and maximizing the efficiency of wireless systems.
