Frequently Asked Questions - A1500.1 AudioControl

What is the recommended power and ground wire gauge for the A1500.1?

Use 4 AWG insulated wire for both +12V and ground connections. For SPIKE MODE (1.33 Ω operation), use 0 AWG power wire with a 0-to-4 gauge adapter (Stinger SSGA104).

How do I connect the A1500.1 to a factory radio?

Connect the speaker-level output of the factory radio to the LC Direct input on the amplifier. Set the Input Level switch to High and the Trigger mode to GTO for automatic turn-on when signal is detected.

What is GTO™ Signal Sense and how does it work?

GTO™ (Great Turn-On) is a feature that automatically turns on the amplifier when it detects an audio signal on the high-level inputs. It eliminates the need for a remote turn-on wire. The amp turns off gracefully after the source unit powers down.

How do I set the gain properly to avoid distortion?

Play music at maximum volume (without distortion) from the head unit. Adjust the Gain dial until the Max. Indicator LED flashes briefly on bass peaks. The LED should not be constantly illuminated; that indicates clipping.

What is SPIKE MODE and when should I use it?

SPIKE MODE allows the amplifier to operate at a 1.33 Ω load, delivering up to 1500W. Use it when connecting three 4 Ω subwoofers in parallel. Requires 0 AWG power wire and proper ventilation.

How do I use the ParaBASS® feature?

The ParaBASS® controls allow you to boost bass at a specific frequency. Turn the Hz knob to select a center frequency (40-80 Hz) and the Level knob to apply up to 10 dB of boost. Useful for compensating for a weak bass response.

Can I use both RCA and speaker-level inputs at the same time?

No, do not use both simultaneously. Choose either the RCA line-level inputs (for aftermarket head units) or the LC Direct speaker-level inputs (for factory radios or amplifiers). Mixing them may damage the amplifier.

What does the Valet Mode do and how to install it?

Valet Mode limits the maximum volume to 25% to protect your system when lending the vehicle. Connect an on/off switch between the Valet terminal on the amp and chassis ground. When grounded, it activates.

Why is the Protection LED red and how do I fix it?

A red Protection LED indicates a fault (e.g., short circuit, thermal overload, or voltage issue). First, cycle power. If it stays red, disconnect speaker wires. If it goes off, check speakers/wiring for shorts. If still red, contact AudioControl technical support.

What is the recommended fuse rating and type?

Use a 150A fuse (AGU or ANL type recommended) installed in a fuse holder near the battery. Always replace with the same type and rating, and only when the amplifier is powered off.

A1500.1

Quick Start Guide

1. 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 amplifier is powered ON.
2. Protection LED – If this LED illuminates red, this signifies the amp is in protection mode and something is wrong. If cycling the power to the amplifier 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 signifies the amp is in Valet Mode.
3. 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.
4. 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 amplifier will gracefully turn on when it detects your source unit powering up, then turn off after the source unit powers down, (Aud) When this mode is selected, the amplifier 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 amplifier will not turn on when using this

turn on mode.

1. 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 amplifier has selectable low pass crossover frequencies at 60 Hz to 120 Hz. The amplifier produces the frequency range below the selected crossover frequency.
2. Subsonic Filter - The Subsonic filter is normally used on a vented subwoofer enclosure. Recommended setting is 1/2 octave below the enclosure tunning frequency.
3. Gain - Use this dial to match the source unit's output voltage with the inputs of amplifier channels 1 & 2. Remember, this is NOT a volume knob.
4. 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.
5. 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 amplifier. 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 amplifier is powered off 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, finished look, the dash control can be flush-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 installation 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 stuff, and not the usual day-time strength.

Quick Start

A1500.1

Here are a few general steps to get your A1500.1 amplifier up and running:

1. Undo the +12V and Ground connections to the car battery before making any connections to the amplifier.
2. Pick a mounting location that will provide access to the controls and connections, provide adequate ventilation, and also protect the amplifier from heat, moisture, and dirt. Make sure that the heat-sink fins are not covered.
3. The A1500.1 amplifier 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 first 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.

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 fly.
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 flash.
15. Set the A1500.1 crossovers to the frequency recommended by the loudspeaker manufacturer.
16. Adjust the Subsonic filter when using a vented enclosure.
17. Enjoy the drive!

The Warranty

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 fine 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 amplifier 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 fixing 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.
