Introduction
Congratulations and thank you for purchasing the Xpress A100 Subwoofer Amplifier!
The A100 may be small in physical appearance but its got all the muscle you need to drive
even the most demanding subwoofers to house thumping levels.
The A100 is a Class D 100 Watts amplifier that when properly installed, runs cool under
almost any load.
The A100 features a stereo/mono line level audio input that can receive full band audio from
any audio amplifier, receiver or preamp or an LFE input from an appropriately featured device.
The adjustable crossover allows fine-tuning the A100 low frequency input setting to properly
complement any full-range speakers or room conditions.
In addition the A100 features a phase adjustment that provides sub performance
optimization given the subs placement relative to the main speakers.
Finally, if you just need more thump, there is a Boost switch that will provide a 6dB boost at
40 Hz...just in case you want some extra kick.
The A100 is auto-sensing so anytime an audio signal hits the A100 inputs, the amp will
instantly turn ON. The amp will also turn itself OFF after 15 minutes when no audio signal is
present. There is also a 12VDC Trigger that will turn the A100 ON when 12-24VDC is applied
and turn the amp OFF when the voltage is removed.
The A100 is the perfect match for many applications but makes a particularly great running
mate with the Xpress D2.1 Stereo amp with subwoofer out, (see the system illustration in the
Connections section).
Please read and follow the instructions in this User Guide to assure you are getting the most
from your new Xpress D2.1 A100 Subwoofer Amplifier.

1. INPUT - Two, RCA jacks. Stereo or mono audio sensing line level audio input. A100 will
turn ON when a line level audio signal is present on either jack. Amp will turn OFF after 15
minutes of no audio signal.
2. TRIGGER - One, 3.5mm mini jack. Connect to the DC voltage Control OUT on an amplifier,
AV Receiver or other audio processor to automatically turn the A100 ON/OFF. When DC
voltage is applied, the A100 will turn ON. When DC voltage is removed, the A100 will turn
OFF. RANGE: +12 to +24V DC. POLARITY: Tip: +VDC, Sleeve: GND.
3. SPEAKER OUT - Two, gold spring push terminals. Connect to a passive subwoofer or a
powered sub with speaker level input.
4. 110/220V - One, switch. Select either 110V-120V or 220V-240V as appropriate for local
AC line voltage. Please confirm local voltage prior to use or making changes to the setting.
5. POWER - One, switch. Set to ON position to turn power to the amp ON. Set to OFF position
to turn power to the amp OFF.
6. AC MAINS - One, three-prong socket. Use the supplied 3-pin ground power cable to
connect the unit to an external AC power supply.

Even though the A100 will typical run cool, the side vents allow air to circulate through the
chassis allowing optimum performance, and besides...they just look cool...get it...air vents...
look cool...never mind...
One serious item...please be sure to not block the vents with wires or other objects that will
block the free flow of air through the amp.

Connections
NOTE: Do not connect the AC power cord or turn the amp on until all connections have been
made and confirmed. Making connections with the power on can result in...well...undesir-
able circumstances...that may not be covered under the factory warranty.
INPUT (A100)
1. Using a stereo or mono RCA-RCA cable with gold ends, connect the LFE OUT, Sub OUT, or
other line level audio OUT on an amplifier, surround receiver or other audio preamp to the
Input on the A100.
SPEAKER OUT (A100)
1. Use16AWG (min) 2-conductor stranded speaker wire for subwoofer connection
2. Strip approximately 1/2 to 3/4 of an inch off the ends and twist the strands together so
there are no loose strands that can cause shorts.
3. While observing proper wire polarity, insert the stripped and twisted ends of the speaker
wire into the appropriate + and - terminals. Be sure there are no loose strands that can
cause shorts.
4. Confirm connection and polarity.
5. Connect the speaker wires to the appropriate + and - terminals on the subwoofer.
6. Confirm connection and polarity.
TRIGGER
1. Using a 2 circuit 3.5mm mini plug, connect +12 to 24VDC from the trigger device to the
striped wire (tip). Connect GND from the trigger device to the unmarked wire (sleeve).
AC MAINS
1. Selects AC power mode (110VAC/220VAC) before connecting to AC power. Set as
appropriate for geographic location.
2. After all connections have been made connect the supplied AC Power Cord to an
unswitched AC power outlet.
NOTE: Do not connect the AC power cord or turn the amp on until all connections have been
made and confirmed. Making connections with the power on can result in...well...undesir-
able circumstances...that may not be covered under the factory warranty.

Once installed and setup, the A100 doesn’t typically need a whole lot of attention. But just in
case you need to tweak something, here’s what you’ll want to do...
ON/OFF
The A100 is auto-sensing, so typically once the system is installed and setup, the power
will automatically turn ON with the presence of an audio signal on either of the L & R Line
Inputs. The amp will automatically turn OFF when no audio signal has been detected for
15 minutes.
TRIGGER - If you are using the Trigger IN, the amp will automatically turn ON when DC
voltage is applied to the Trigger jack and turn OFF when DC voltage is removed..
POWER - If however you are a major control freak and just have to have the ability to turn
the amp ON/OFF, toggle the Power ON/OFF button once to turn the amp ON/OFF.
VOLUME - Adjust the volume to the subwoofer until low frequency level has a smooth,
natural sounding transition from the left and right speakers.
PHASE - The Phase setting allows compensation for subwoofer location relative to the main
speakers. Adjust the Phase setting to the point of highest sub audio output.
RANGE: 0º to 180º.
CROSSOVER - The Crossover sets the frequency at which audio content will pass to the A100
Speaker Out. Adjust the crossover so there is a slight overlap with the low-midrange cut-
off to produce a natural sounding transition to low frequencies.
RANGE: 40Hz to 160Hz.
BOOST- Set to 0dB for normal signal. Set to 6dB for 6dB boost @ 40Hz.
