About Room Equalization

This section gives some background on room equalization. As a sub plays in a room, the reflections of the sound waves off the walls create “standing waves,” that is, places in the room where certain frequencies are louder and others are diminished. In addition to standing waves, every room will also have locations where cancellations of the sound waves are like black holes that no amount of attenuation can fill. Thus as a general rule it is better to “cut down” a peak of response rather than to “boost up” a valley (i.e. possible black hole) of response.

In general, you are looking for a frequency response that is +/– 3 dB at all frequencies (it is highly doubtful that your ear can tell a response that is any better than this). The response will always roll off at the low end (according to the settings of the subsonic filter), and there should be no dip or peak at the crossover frequency with the satellites. While the goal is perfectly flat response, this may not be possible in the higher frequencies of the subwoofer’s response due to peaks or valleys introduced by the satellites.

Protection Circuitry

Your new subwoofer is equipped with special protection circuitry to provide maximum performance with greatest reliability.

The unit is protected against:

1.Overdriving the speaker or amplifier.

2.Overheating the amplifier.

3.Excessive drop in power line voltage.

The first type of protection circuitry that prevents overdriving of the speaker or amplifier operates constantly without being audible under most situations. In some extreme situations (sustained high output levels such as pro sound usage), the unit may shut down momentarily. This indicates operation of the thermal or under voltage protection circuitry. If this should happen, you should reduce the volume setting or shut the unit off until normal operating conditions return. You may also want to plug the unit into a different wall outlet, as dropping power line voltage will be most noticeable under strenuous conditions.

Car e of Your Digital Subwoofer

Do not use any harsh detergents or chemicals to clean the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using a damp cloth to clean the cabinet. During normal conditions, your new subwoofer may be left on continuously without any problems. The unit is equipped with a signal-sensing turn on/off that will automatically turn on the unit when a signal is present at the inputs and turn off the unit after several minutes when there is no longer any signal at the inputs. If you plan to leave the subwoofer unused for an extended period of time, we recommend that you unplug the unit.

Digital Drive specifications

Velodyne Acoustics, a pioneer in advanced audio technology, has consistently pushed the boundaries of sound reproduction. Among its innovations, the Velodyne Acoustics Digital Drive stands out as a remarkable achievement in subwoofer design. This high-performance audio component is engineered to deliver deep, powerful bass while maintaining clarity across a wide frequency range, making it a favorite among audiophiles and home theater enthusiasts alike.

One of the standout features of the Digital Drive subwoofer is its sophisticated digital signal processing (DSP). This technology allows for real-time adjustment of bass response according to the unique acoustic characteristics of the room. Users can fine-tune their listening experience through an intuitive interface, enabling them to achieve the optimal sound profile that suits their space. The DSP also provides advanced features such as room gain correction, which helps mitigate the negative effects of room acoustics on sound quality.

Another significant characteristic of the Velodyne Digital Drive is its powerful, high-efficiency amplifier. Designed to deliver substantial power to the subwoofer driver, the amplifier ensures robust performance without distortion even at high volume levels. This capability allows for an immersive listening experience whether watching movies, playing video games, or enjoying music.

The Digital Drive subwoofers are equipped with precision-engineered drivers that are optimized for low-frequency reproduction. With a focus on producing deep bass notes with accuracy, these drivers work in harmony with the cabinet design to minimize unwanted resonances. The result is a seamless bass response that enhances the overall audio experience.

Moreover, the Digital Drive subwoofers feature user-friendly connectivity options, including RCA and XLR inputs, allowing them to integrate effortlessly into existing audio systems. The subwoofers can be controlled via a remote, making it easy for users to adjust settings without getting up from their seat.

In addition to these advanced features, the Velodyne Digital Drive subwoofers boast a sleek, modern aesthetic that will complement any home decor. The compact design allows for easy placement in various settings while still delivering the powerful bass that Velodyne is known for.

In summary, the Velodyne Acoustics Digital Drive subwoofer epitomizes the marriage of cutting-edge technology and superb audio performance. With its digital signal processing, high-efficiency amplification, precision-engineered drivers, and user-friendly features, it remains a top choice for anyone looking to elevate their audio experience. Whether for casual listening or serious home theater applications, the Digital Drive is a testament to Velodyne's commitment to high-quality sound.
