Introduction

The LS801P is a premium quality integrated subwoofer and power amplifier. Created as an easy-to-setup addition to any P.A., the LS801P will extend the bass of a typical sound system with the least amount of complication. The LS801P has been intended to operate primarily with line level signals (with the option to accept Speaker Level signals).

Configuration

The LS801P may be used in several different configurations. The basic system is a single LS801P used for each full range enclosure or multiple LS801Ps along with individual full range enclosures. The LS801P accepts, and combines, the signals from separate line level (e.g. Left and Right) sources. Using the Mono Blend XLR input combines the second line level signal properly to drive the internal speakers and does not affect the stereo separation of the full range enclosures. When used in a setup where only one signal is provided to a speaker, such as a mono system or stereo with more than one LS801P, you can use any of the Link jacks.

1. Input Level Switch

The Input Level switch is provided to switch the Input Level between line level and speaker level. This switch should be set to speaker level when the LS801P is fed from the output of an amplifier or ‘powered’ mixer. Do not plug in two Speaker Level sources to one LS801P. The line level position is for use when the LS801P is fed a signal directly from a processor, electronic crossover or the output of an ‘unpowered’ mixer. When using the line level mode, the use of balanced (Tip, Ring, Sleeve) and/or XLR cables will reduce the unit’s sensitivity to hum and buzz.

2. LS801P Level Control

The LS801P Level control adjusts the amount of bass added to the sound system by the LS801P. This adjusts for the relative sensitivity of the companion full range speakers and the desired system frequency response. This control should be set by listening while operating at a medium level and then not changed. It is not possible to set this control properly at high levels since the limiter is determining the output level.

A setting of 0 dB on the LS801P Level control is the correct starting point when setting up a sound system. From there, adjustments can be made for the best sound. The 0 dB mark refers to the setting that will give full power when the line input is used and the input signal is at a level of +4 dBV.

3. Shape Control

The Shape control enables tweaking of the most effective sub frequency, 50 Hz. You can boost or cut the equalization of the enclosure (50Hz) by a range of 6 dB (+ 3dB / -3dB).

Note: In High SPL situations a louder volume can be achieved by not using the Shape control in its full clockwise position.

4. HF Rolloff Frequency Control

The HF Rolloff Frequency control varies the frequency at which the LS801P rolls off the high frequencies. This provides part of a crossover function. This crossover function also combines with the natural low frequency rolloff inherent of the full range enclosure (when the LS801P is not used with an élite processor). An elite processor may be used to provide the LF rolloff of the full range loudspeaker. Ideally the LS801P would then be wired ahead of this processor. In this case the LS801P HF rolloff should match the LF crossover point of the elite processor. The elite processor should be set in the mode intended for use with a subwoofer. An elite processor may be used ahead of the LS801P in which case the LS801P HF rolloff should be set to maximum.

5. LINK Jacks

The Link jacks are set up to make it easy to hook up your LS801P to any audio system with a minimum of hassles. SInce all of the Link

LS801P specifications

The Yorkville Sound LS801P is a powerful and versatile subwoofer that showcases advanced technology and premium materials, making it an ideal choice for both live sound applications and permanent installations. Designed to provide deep, impactful bass, the LS801P is particularly favored by sound engineers and musicians who demand high-quality audio performance in various settings, from concert venues to clubs and corporate events.

One of the standout features of the LS801P is its 18-inch low-frequency driver. This driver is engineered to deliver robust bass response and excellent sound clarity, enabling the subwoofer to reproduce low-end frequencies with precision. The cabinet of the LS801P is constructed from durable plywood and features a rugged, roadworthy exterior, ensuring it can withstand the rigors of transportation and frequent use. The speaker is also designed with internal bracing, reducing unwanted resonance and enhancing overall sound quality.

The LS801P incorporates a built-in 800-watt Class D amplifier, providing ample power to drive the subwoofer in a variety of settings. This efficient amplification technology not only ensures high performance but also helps reduce the overall weight of the unit, making it easier to transport and set up. The amplifier features protective circuitry, maintaining operational integrity while preventing damage from overheating or overload.

Another key technology utilized in the LS801P is its advanced DSP (Digital Signal Processing) capabilities. The built-in DSP allows for precise tuning of the audio output, enabling users to tailor the sound profile to suit specific environments and requirements. This feature is invaluable in live sound applications where the acoustics of a venue can significantly affect sound quality.

In terms of connectivity, the LS801P is equipped with both XLR and 1/4-inch inputs and outputs, allowing for easy integration with other audio equipment. The speaker is designed with flexibility in mind, making it compatible with a variety of PA systems and setups.

The LS801P also includes a phase switch, allowing users to optimize the bass response when deploying multiple subwoofers. This feature can significantly enhance the overall sound experience by ensuring that the low frequencies are well-defined and balanced.

Overall, the Yorkville Sound LS801P stands out as a top-tier subwoofer that combines innovation, durability, and exceptional sound performance. Its robust construction and advanced features make it an excellent choice for professionals seeking a reliable and powerful low-frequency solution in their audio setups. Whether for live events or permanent installations, the LS801P delivers the deep bass that audiences crave, making it an indispensable tool for sound reinforcement.
