1Ω Stable: The D1000.1 can power loads as low as 1Ω;
the RMS power output is 400 watts at 4Ω, 700 watts at 2Ω, and 1100 watts
Strapping Amplifiers: Two D1000.1s can also be strapped
together (they must be identical D1000.1s) to power a single subwoofer. When
used in this configuration the RMS power output is 2200 watts at 2Ω and
1400 watts at 4Ω (2Ω is the minimum load).
Remote Level Control: The amp has an RJ-14 jack for use with
the supplied wired remote level control. The remote's rotary knob allows you to
adjust the amp's output level between no output (minimum) and the gain setting
on the side of the amp (maximum) from your listening position. The remote has
integrated mounting flanges and includes two mounting screws to secure it to a
flat surface in the front of the vehicle. The dimensions are 2" wide x 15/16"
tall x 1-5/8" deep (2" including knob).
LEDs: Power and Protection LEDs are located on the side of
the amplifier. A blue Power LED illuminates when the amplifier is turned on and
operating normally. A red LED illuminates when any of the amplifier's protection
circuits engage; thermal, short circuit, or too low an impedance.
Gain: The amplifier's input gain setting is adjusted to match
the incoming signal voltage. The gain is continuously variable from 150 mV to 5.0
Bass Boost: The bass boost is variable from zero to +12 dB.
Bass Boost Frequency: The center frequency of the bass boost
circuit is continuously variable from 30 Hz to 125 Hz.
Subsonic Filter: This high-pass filter (variable from 16 Hz
to 60 Hz) is designed to prevent frequencies below the audible range from being
directed to the subwoofer. The subsonic filter improves your subwoofer performance
and power handling, particularly in vented enclosures. The subsonic filter cannot
Crossover Frequency: The low-pass crossover frequency is
continuously variable from 50 Hz to 250 Hz. The slope is 24 dB/oct and the
low-pass crossover cannot be bypassed.
Source: When using multiple D1000.1 amps in a master/slave
configuration, change the source switch from normal to slave if this amp's input
is supplied by the master amp.
Phase: If needed, the phase of the D1000.1 can easily be
reversed to blend better with the rest of the system; choose 0° or 180°. The
phase switch is also used when strapping two amps together.
Power Connections: The power and ground terminals are nickel
plated set screws and will accommodate up to 4-gauge wire. An external 100-amp
fuse (not included) must be installed on the power wire. If a wiring kit is used
which includes a fuse with a value other than 100-amps, the original should be
replaced with a 100-amp fuse. The remote turn-on terminal will accept up to
10-gauge wire. 4mm (power and ground) and 2mm (remote) Allen wrenches (not
included) are required to tighten/loosen the terminals.
Dual Speaker Terminals: The amplifier features two pair of
speaker output terminals so you can easily connect two subwoofers. The nickel
plated set screw terminals will accept up to 8-gauge wire. A 3mm Allen wrench
(not included) is required to tighten/loosen the terminals.
RCA Inputs: The D1000.1 features a pair of RCA input jacks
for easy connection to the source unit's line level output. The RCA input jacks
are nickel plated to resist signal degradation caused by corrosion.
RCA Outputs: The amplifier also features a pair of Pass-Thru
RCA jacks, providing a convenient method of daisy-chaining an additional amplifier
without running an extra set of RCA cables from the front of the vehicle. The RCA
output jacks are nickel plated and are unaffected by the D1000.1's crossover and
bass boost circuitry.
Slave in/out: A single RCA slave input and a single RCA slave
output are used when two D1000.1s are strapped together to power one subwoofer, or
when multiple D1000.1s are linked together to power multiple subs using the same
Remote: An RJ-14 jack is provided for connecting the
included remote level control. The remote adjusts between no output (minimum)
and the gain setting on the side of the amp (maximum).
