Figure 1. Installation Using LFE Line-Level Inputs

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 turn off the master power switch on the rear panel.

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 which 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 the thermal or under-voltage protection circuitry has engaged. 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 and may result in the unit shutting down intermittently.

SPL-800i specifications

The Velodyne Acoustics SPL-800i is a highly regarded subwoofer that exemplifies performance excellence in home audio systems. Known for its powerful bass response and intelligent design, it enriches the listening experience by providing deep, impactful low-frequency sound without compromising clarity.

One of the defining features of the SPL-800i is its innovative DSP (Digital Signal Processing) technology. This sophisticated system optimizes the sound output, ensuring that the subwoofer reproduces low frequencies accurately across various music genres and types of audio content. The DSP-enabled design facilitates seamless integration with other speakers, creating a cohesive sound stage that enhances overall audio enjoyment.

The SPL-800i is equipped with an 8-inch downward-firing driver. This configuration not only maximizes the efficiency of the low-end response but also minimizes distortion, resulting in clean and precise bass output. The driver's robust construction ensures durability while delivering powerful performance capable of shaking the walls without losing musical fidelity.

Another notable characteristic of the SPL-800i is its compact form factor. Designed to fit easily into various home environments, it measures a modest size, making it a versatile choice for both small and large rooms. Despite its size, the subwoofer manages to deliver impressive power, with a built-in 300-watt amplifier that drives its performance.

The SPL-800i also features an adjustable phase control, allowing users to match the subwoofer output to their room acoustics and listener location. This customization enhances the overall sound quality and makes the subwoofer adaptable to different setups, whether in a dedicated home theater or a multi-purpose living area.

Further enhancing user experience, the SPL-800i includes automatic room equalization that helps in calibrating the subwoofer to its environment. This advanced technology assesses the space and adjusts its performance to eliminate unwanted frequencies, ensuring the best bass reproduction possible.

In summary, the Velodyne Acoustics SPL-800i stands out in the realm of subwoofers thanks to its unique blend of advanced technologies and thoughtful features. With its DSP technology, powerful driver, compact design, and room calibration capabilities, it remains a top choice for audiophiles looking to enrich their home audio experiences with deep, professional-grade bass.
