Overview: The Jensen DUB Edition amplifiers offer
performance and value for your vehicle's sound system. With a MOSFET power
supply and high-current Toshiba bi-polar output transistors, the DUB amps
provide lots of power and control to give your music impressive punch and
clarity. The Class AB design reduces idle current and minimizes distortion.
Power Output: The DUBa2100 2-channel amplifier delivers
the following power output:
- CEA Specifications: RMS power output @ 1% THD+N, 20-20kHz, 14.4 VDC:
- 80 watts x 2 @ 4 ohms
- 120 watts x 2 @ 2 ohms
- 235 watts x 1 bridged mono @ 4 ohms
- RMS Power Output @ 2% THD+N, 1 kHz, 14.4 VDC:
- 85 watts x 2 @ 4 ohms
- 125 watts x 2 @ 2 ohms
- 240 watts x 1 bridged mono @ 4 ohms
Protection Circuitry: The amplifier features protection
circuitry for thermal overload, DC-offset, and short circuits. The LED on the
top of the amp glows yellow if a fault is detected.
Pass-thru RCAs: The DUBa2100 has a pair of RCA connectors
that allow you to connect additional amplifiers without having to use a
Y-adapter. The line output is unfiltered, providing the same signal as the RCA
End Caps: The DUB Edition amps include end caps to cover the
wiring and controls for a clean installation. The end caps can be painted to
match your vehicle, if desired. The end cap brackets can be removed if you wish
to install the amp without the end caps.
Input Level: The DUBa2100's rotary gain control let you match the
amp's input sensitivity to the output of the source unit. The input sensitivity
range of the amplifier is continuously variable between 400mV and 5V. A small
screwdriver (not included) is required to set the gain.
Crossover: The amp features a 12 dB/octave crossover that is adjustable from 40 to 300 Hz.
A 3-way switch lets you configure the crossover for high-pass or low-pass
operation, or switched to full-range to defeat the crossover.
Bass EQ: The DUBa2100 has a 0 to 12dB bass EQ,
centered at 45Hz. This is useful for varying the amount of bass if you're
running the amp in bridged mono for a subwoofer. Ported and Bandpass enclosures
should be limited to approximately +6dB to +9dB of boost, while sealed
enclosures should be able to accept the full +12dB of boost.
Mono/Stereo Switch: The Mono/Stereo switch should be set to
Stereo when you have a 2-channel input from the head unit. If there is only a
single input from the source unit, you can drive both channels of the amp from
the single input by switching to Mono.
Terminals: The Jensen DUBa2100 uses screw
terminals for the +12V power, ground, turn-on (remote) lead, and speaker
outputs. The screws can be tightened/loosened with a Phillips-head or
screwdriver (not provided).
Power/Ground: The +12V Power and Ground terminals will
accept spade connectors up to 7/16" (0.4375") wide. It is recommended that you use an
8 AWG power wire to the battery, with an in-line 25A fuse installed no more than
18" from the battery terminal. An 8 AWG ground wire (minimum) should be used, and
attached to a metal area close to the amplifier.
Remote Turn-On: The Remote screw terminal will accept a
spade connector up to 5/16" (0.3125"). Typically, an 18 AWG turn-on lead is included in an amplifier
Low-Level Input: The amplifier is equipped with a pair of
RCA inputs for connecting a stereo RCA patch cable from the head unit to the
amp. A stereo RCA line output is also provided for daisy-chaining another
amplifier without requiring a Y-adapter.
Speaker Outputs: The amp features two positive and two
negative screw terminals for connecting two speakers in stereo. To bridge the
amp, you should connect the left + and the right - terminal to the speaker. The
terminals will accept a spade connector up to 5/16" (0.3125") wide. It is recommended
that you use a minimum of 12 AWG wire.
Tri-Mode: The amp is capable of being connected in Tri-Mode
to drive a pair of full-range speakers and a subwoofer. A passive Tri-Mode
crossover (or capacitors and inductors) should be connected to high-pass the
full-range speakers and low-pass the subwoofer.
