Inputs and Outputs Notes
Class-D Digital Amplifier:
The SPL-1000R features Velodyne's patented ERS (Energy Recovery System) Class-D
digital amplifier. The amp delivers 1000 watts RMS and 2000 watts dynamic power. Rated at over 97% efficiency, the ERS amp
generates minimal heat, making it incredibly reliable.
Kevlar Reinforced Driver:
To compliment the powerful amplifier, the subwoofer uses a 10" driver
with a multi-layer, Kevlar reinforced, resin cone and high-excursion EPDM rubber
surround mounted in a die-cast aluminum basket, and a massive 346 oz (21.63
Two-layer Copper Voice Coil:
incorporates a unique 3 inch, inside/outside wound, two-layer copper voice coil that assures
linear travel, and allows for the heat dissipation needed to handle the power
delivered by the 1000 watt ERS amp.
Texas Instruments DSP chips and customized software are used to accurately
adjust the SPL-1000Rs sonic parameters, resulting in a fantastically detailed
bass output. DSP circuits are used in the volume, EQ, crossover, preset, phase,
night mode, and gain limiting controls.
Driver Displacement Control
Circuit: The Driver Displacement
Control circuit prevents over excursion of the woofer and and amp clipping.
Low-pass Crossover: The
crossover control allows you to adjust the upper limit of the subwoofer's
frequency response from 40 to 120 Hz. The crossover slope is 12 dB/octave. The
amp has an additional low-pass crossover of 36 dB/octave, creating a cascade
crossover system of 48 dB/octave.
Turning the crossover knob to the counterclockwise most position engages the
Subwoofer Direct feature, bypassing the pre-amp level crossover and allowing
frequencies up to 200 Hz to pass to the woofer. This feature is used with an
The remote control allows you to adjust the phase of the subwoofer's output signal
in 90° increments (0°,
90°, 180°, and 270°) to
optimize the sub's performance, given it's location and your listening position.
Auto Turn-on Function: With
this function in the "auto" position, the subwoofer will turn itself on
automatically when an audio signal is present. If no signal is present for
approximately 15 minutes, the unit will switch to standby mode. When the auto-on
feature is turned off, the sub remains on unless you manually turn it off.
The protection circuitry guards
overdriving the speaker or amplifier, overheating the amplifier, and excessive
drop in power line voltage.
SPL-1000R has an internal 6-band EQ that is
automatically set using the included microphone. With the mic in your listening
position, engage the auto EQ feature using the remote and the sub emits 12 sweep
tones covering frequencies from 20 to 150 Hz and optimizes the EQ settings for
There are four presets designed for specific applications:
Maximum output and impact for special effects (25 Hz subsonic filter/5 dB
boost at 35 Hz/5 dB volume boost)
Driving bass for today's rock and R&B music (28 Hz subsonic filter/1 dB
boost at 55 Hz/1 dB volume boost)
Tightest, cleanest, lowest distortion bass (15 Hz subsonic filter with no
bass or volume boost)
Maximum loudness for video game impact (34 Hz subsonic filter/4 dB boost at
62 Hz/4 dB volume boost)
A blue LED on the front of the sub indicates the power is on. The LED turns off
when the sub goes into standby mode. The LED also blinks to indicate volume
changes, mute, phase, night mode, and preset changes. The LED can be manually
turned off if you prefer.
Using the Night Mode limits the maximum output of the sub.
The SPL-1000R includes a wireless remote that controls power, volume, EQ,
presets, phase, mute, light, and the night mode. An IR sensor is on the front of
the sub in the upper right corner. The remote's dimensions are; Width: 1.896",
Height: 3.276", Depth: 0.802"
Inputs and Outputs Notes
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. If inputting a mono LFE signal, no Y adapter is necessary.
Preamp Level Output
The stereo line-level output has an 80 Hz/6 dB per octave high-pass crossover for use
with a pre-amp. The preamp output is only useful when a full range stereo signal
is sent to the preamp inputs.
Speaker Level Input:
The speaker-level jacks connect directly to the speaker outputs of any
amplifier, integrated amplifier, or receiver. Your amplifier section will notice
no additional load when you use these inputs due to their high
impedance. The speaker inputs have 5-way binding posts.
Mic Input: The included
microphone plugs into a mini-jack input on the back of the sub.
IR Input: A mini-jack IR input
is used if you have a universal remote system with IR repeater.
12V Trigger: If a mini-plug is
connected to this jack, the sub remains off until 12 volts is applied across the
terminal. Polarity is irrelevant.
