10. Power LED - If you have connected your battery power, vehicle
ground, and turn-on lead (or used an alternative signal sensing
turn on mode correctly), then this light should be illuminated
white to indicate the amplier is powered ON.
11. Protection LED – If this LED illuminates red, this signies the
amp is in protection mode and something is wrong. If cycling
the power to the amplier does not take amp out of protection
then disconnect speaker wires and cycle power. If the amp is no
longer in protection then check speaker and wires for shorting.
If light stays on with speaker wires disconnected then contact
AudioControl Technical support for further instruction. If the LED
illuminates amber, this signies the amp is in Valet Mode.
12. Input Level Switch – High (LC Direct) = 1.5-20 volts, Low (RCA)
= 0.5 -6 volts. Select High for most systems using a factory stereo
as the source. Select Low for most systems using an aftermarket
source unit, LOC, or DSP.
13. Remote / GTO / Audio – (Rmt) Select this mode when the remote turn-on signal from an aftermarket head-unit, LOC, or DSP
is present to turn the amp ON. (GTO™) for Ch 1 High Level Input
Only: Choose this mode when no turn on signal is available, and
the amplier will gracefully turn on when it detects your source
unit powering up, then turn o after the source unit powers
down, (Aud) When this mode is selected, the amplier will turn
ON when it detects audio signal from Ch 1 is present on the
inputs, regardless of the source. If you turn the head unit on, but
DON’T play audio, the amplier will not turn on when using this
turn on mode.
14. Low Pass Crossover – A crossover allows you to match a speaker
to the frequency range it is designed to handle. Choosing the
crossover point recommended by the speaker manufacturer will
provide increased speaker reliability and optimum sound quality.
The A1500.1 amplier has selectable low pass crossover frequencies at 60 Hz to120 Hz. The amplier produces the frequency
range below the selected crossover frequency.
15. Subsonic Filter – The Subsonic lter is normally used on a
vented subwoofer enclosure. Recommended setting is 1/2
octave below the enclosure tunning frequency.
16. Gain – Use this dial to match the source unit’s output voltage
with the inputs of amplier channels 1 & 2. Remember, this is
NOT a volume knob.
17. Max. Indicator – This LED indicates when channels 1&2 have
been optimized for maximum performance. This LED should
illuminate momentarily during brief bursts of music playback
at max volume. In most scenarios, it should not be constantly
illuminated for long periods of time.
18. ParaBASS® Two simple controls allow for killer bass tweaking.
The ParaBASS (Hz) knob selects the center frequency, between
40 Hz and 80 Hz. The level knob provides up to 10 dB of boost
centered around the ParaBASS® frequency.

ACR-1 (Optional)
ACR-1 remote
The optional AudioControl ACR-1 dash control is a remote level
control for your A1500.1 amplier. It may be mounted under the
dash using its own enclosure, or through a custom hole in the
dash. The level control knob should be within reach of the driver,
and in a spot where the LED is plainly visible. Insure the amplier
is powered o when connecting the ACR-1.
Dash Bracket Installation: The dash control mounts with two screws,
which attach to the underside of the dashboard. Slide under the
dash and place the dash control in its mounting position, mark
the two best mounting holes, drill pilot holes, and secure with two
screws.
Custom Installation: For that custom, nished look, the dash control
can be ush-mounted directly on the dashboard (or anywhere
else). See ACR-1 manual/packaging for details and diagram.

The long-awaited moment when “plethora” is used in a manual
The plethora of A1500.1 controls allows for a wide variety of in-
stallation possibilities. This quick start guide gives a few examples
of system diagrams reference (pages 11-13) and includes a few
notes about the control settings for each one.
Note: The technical writer reserves the right to be wrong about things, due to the
cold medicine being the night-time sleepy stu, and not the usual day-time strength.

Quick Start
Here are a few general steps to get your A1500.1 amplier up and
running:
1. Undo the +12V and Ground connections to the car battery
before making any connections to the amplier.
2. Pick a mounting location that will provide access to the controls
and connections, provide adequate ventilation, and also protect
the amplier from heat, moisture, and dirt. Make sure that the
heat-sink ns are not covered.
3. The A1500.1 amplier needs to be securely mounted using the
four mounting holes located in each corner.
4. Before drilling any holes, take every precaution to prevent any
damage to fuel lines, power and other electrical wiring, hydraulic
brake lines, and other systems, that might compromise
vehicle safety.
5. When making connections, designate red RCA plugs as right,
and designate white, black, or grey plugs as left. This is a good
idea for consistency.
6. Use quality interconnect cables.
7. Always connect the amps Ground terminal rst before connecting the 12V power wire to the amp. Not following these instructions could result in damaging the amp and this would not be
covered under warranty. Also NEVER REMOVE THE GROUND
WIRE from the amp while the 12V wire is connected.
A1500.1
8. Connect the Ground terminal of the unit to the chassis of the vehicle, using 4 AWG wire. Connect the +12V wire using the same
gauge wire as the ground wire.
9. Connect the remote power terminal of the amp to the remote
turn-on output of your source unit. Alternatively, you can skip
this connection and use the GTO / Aud turn-on method.
10. Connect your audio inputs to the amp – either speaker-level or
line-level RCA… not both.
11. Run the optional ACR-1 remote to the front of the vehicle to
adjust the output level on the y.
12. Connect your loudspeakers (2ohm suggested or 1.33 ohms for
SPIKE MODE.)
13. When all connections are made, reconnect the vehicle battery.
14. Adjust your input source gain using the MAX Clip LED. When the
Audio is playing look at the light and when the music peaks the
light should ash.
15. Set the A1500.1 crossovers to the frequency recommended by
the loudspeaker manufacturer.
16. Adjust the Subsonic lter when using a vented enclosure.
17. Enjoy the drive!

The Warranty
16
A1500.1
In just the same way as walking into a room and seeing a big hairy spider on
the wall, people are scared of warranties. Lots of ne print.
Months of waiting around. Well, fear no more. This warranty is designed to
make you rave about AudioControl. It’s a warranty that looks out for you and
your client, plus helps you resist the temptation to have your friend Sparky,
who’s “good with electronics,” try to repair your AudioControl product. So go
ahead, read this warranty, then register the information at www.audiocontrol.
com/product-registration and include your comments.
Our warranty has conditional conditions! “Conditional” doesn’t mean
anything ominous. The Federal Trade Commission tells all manufacturers to
use the term to indicate that certain conditions have to be met before they’ll
honor the warranty. If you meet all of these conditions, AudioControl will,
at its discretion, repair or replace any AudioControl Altitude products that
exhibit defects in materials and/or workmanship for one (1) year from the
original date you bought it. We will repair or replace it, at our option, during
that time.
Here are the conditional conditions:
1. You must fully register your purchase within 15 days of the purchase date
by going to the AudioControl product registration page at:
www.audiocontrol.com/product-registration
Failure to register your product will negate the warranty.
2. You need to hold on to your sales receipt! All warranty service requires
original sales receipt documentation. The warranty only applies to
the original purchaser from an authorized AudioControl dealer. Note:
Products purchased from unauthorized dealers are not covered under
warranty.
3. The AudioControl Altitude products must have originally been purchased
from an authorized AudioControl dealer. If an authorized AudioControl
dealer installs your AudioControl product, they also must use all Stinger
power management and the warranty is extended to (3) years.
4. Our warranty covers AudioControl products that have been installed
according to the instructions in this manual.
5. You cannot let anyone who isn’t: (A) the AudioControl factory; or
(B) someone authorized in writing by AudioControl, service your
AudioControl product. If anyone other than (A), or (B) messes with your
AudioControl product, the warranty is void.
6. The warranty is void if the serial number is altered, defaced or removed,
or if your product has been used improperly. Now that may sound like a
big loophole, but here is what we mean by this: Unwarranted abuse is:
(A) physical damage (don’t use your product to pound in fence posts);
(B) improper connections (120 volts into the amplier terminals can fry
the poor thing). This is the best product we know how to build, but for
example, if you mount it to the front bumper of your car, drop it over
Niagara Falls, or use it for anchoring your boat, something will go wrong.
Assuming you conform to 1 through 6, and it really isn’t all that hard to do,
we get the option of xing your product, or replacing it with a new one, at our
discretion.
In the event that your product is out of warranty or not covered under our
warranty, you may request to have any damage repaired at our normal “Out of
Warranty” repair cost.
