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.
