Alpine Authorized Online Dealer

If you're serious about bass, the DLS-4000R from Velodyne may be the perfect subwoofer for you. It includes a high-powered 200-watt amplifier and a massive 12" long-throw woofer for big, room-rattling bass. Plus, it features advanced circuitry that controls all the sub's functionality with incredible accuracy. From the high-impact excitement of home theater to the delicate acoustic bass lines of a jazz quartet, the DLS-4000R delivers dynamic bass with amazing warmth and clarity. And the included remote control lets you adjust the sub's volume and access other functions from the comfort of your favorite chair.


Precision digital signal processing

DSP chip

Enjoy incredibly accurate bass thanks to the DLS-4000R's DSP circuitry.

The key to the DLS-4000R's exceptional sound is in the digital signal processing (DSP). DSPs are embedded computer chips that monitor the audio functions of the subwoofer. It's like having your bass controlled with the accuracy of a high-speed computer. DSP subwoofers have never been available in this price range before — usually, they cost at least twice this much.


Remote

Flexible bass control at the push of a button

With the DLS-4000R, Velodyne give you flexible control over the bass output. Four customized audio presets — Movies, Rock, Jazz/Classical, Games — allow you to fine tune the sub's sound to suit your tastes and source material.

The DLS-4000R features flexible connectivity options, so it's easy to incorporate this sub into your existing system, whether for stereo music or home theater. You get line-level and speaker-level inputs, including a crossover bypass for 5.1 home theater bass precision. There's even a stereo line-level output with a selectable 80 Hz or 100 Hz high-pass crossover for use with a pre-amplifier.

Features

Maximum Dynamic Power Amplifier: The DLS-4000R amplifier is capable of delivering enormous continuous and reserve dynamic power. The subwoofer is driven by 200 watts of continuous RMS power and 400 watts of dynamic power.

Reinforced Fiber Driver: To compliment the powerful amplifier, the subwoofer uses an extended excursion driver with a reinforced fiber cone and foam surround. The driver is engineered with a vented pole-piece that increases power handling and assures long-term reliability.

Distortion Limiting System: This system, programmed into the subwoofer's DSP, maximizes usable amplifier power and provides maximum available cone travel without overdriving. The software parameters used for the DLS system are customized for each DLS-R amplifier and driver. With digital precision, it is possible to achieve the maximum allowable performance from both the amplifier and woofer motor structure without overdriving either. The result is deeper bass extension, bigger impact and cleaner output.

Bass-reflex Design: The cabinet features a slot-loaded, front-firing, bass-reflex design. This approach minimizes the distortion created in ported cabinets known as "port noise" and maximizes bass impact.

Anti-clipping Circuitry: The sub incorporates anti-clipping circuitry to limit amplifier clipping distortion.

Controls

Low-pass Crossover: The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 120 Hz.

High-pass Crossover: The high-pass crossover can be set to 80 or 100 Hz. This crossover is functional on both line and speaker-level outputs.

DSP Controlled: Presets for customized listening, volume control, night mode, low-pass crossover, phase, anti-clipping and overdrive protection are all controlled with the precision of a high-speed computer. DSP technology means that the subwoofer delivers the cleanest, deepest, and highest output bass possible, while maintaining a flat, detailed and accurate frequency response.

Remote Control: The supplied remote lets you control the following functions:

  • Power: This button forces the subwoofer into standby mode. The woofer will not play and the LED will turn off. The unit will remain in this mode until the power button is pressed again.
  • Mute: This button mutes the subwoofer.
  • Phase: This control allows you to optimize the subwoofer performance based on its location and your listening position. You can select one of the following settings: 0°, 90°, 180°, or 270°.
  • Light: If you wish, you can deactivate the blue front panel light on this unit.
  • Night: Night mode limits the maximum output of the subwoofer for late night listening.
  • Volume +/-: This control allows you to balance the output from the subwoofer to the main speakers in your system. You can also control the volume from the back panel of the subwoofer.
  • Presets: You can choose any of the following presets:
    • Movies: maximum output and impact for explosions and other action adventure movie content
    • R&B - Rock: provides the driving bass found in today's rock music
    • Jazz - Classical: offers the tightest, cleanest, lowest distortion bass
    • Games: maximum loudness available for the impact of video games

Subwoofer Direct: To bypass the subwoofer's internal crossover when the unit is being fed a low-pass signal from another crossover, simply select the Subwoofer Direct mode. This will eliminate the internal crossover from the signal path.

Auto Turn-on Function: With this function in the "active" position, the subwoofer will turn itself on automatically when an audio signal is present. If no signal is present for a period of time, the unit will switch to standby mode.

Connections

Preamp Level Input: The line-level jacks should be used when connecting the subwoofer to a pre-amp, signal processor, line-level crossover, or receiver with pre-amp level outputs.

Preamp Level Output: This stereo line-level output has an 80 or 100 Hz high-pass crossover for use with a pre-amp.

Speaker Level Input: The speaker-level jacks connect directly to the speaker outputs of any amplifier, integrated amplifier, or receiver.

Speaker Level Output: The speaker outputs send a crossed-over signal to the front speakers. This output is affected by the high-pass crossover, which can be set to 80 or 100 Hz.
