The D-4.800's advanced DSP (Digital Signal Processing) and matrixing technology provide unparalleled sound quality, allowing you to hear every detail of your music like never before. And with an all-aluminum chassis that is both durable and stylish, this amplifier is built to last.

Whether you're a music enthusiast, audiophile, or simply love to jam out on the road, the AudioControl D-4.800 4-Channel Car Amplifier with DSP & Matrixing is the ultimate choice for upgrading your car audio system. So what are you waiting for? Grab your shades, roll down the windows, and turn up the tunes with the D-4.800!

  • Maximum Input Level Control (MILC): The amplifier analyzes the input signal to detect any clipping. If the signal reaches the level of clipping, the MILC Source Clip LED glows red, prompting you to turn down the gain level. When the gain level is maximized, a green Maximized LED will glow to indicate the gain, for that set of channels, is set to the optimum level.

  • GTO (Great Turn On) Signal Sense: If you are connecting the amplifier to a factory stereo, or an aftermarket unit without preamp outputs and a remote turn-on lead, the GTO Signal Sense circuitry can turn on the amplifier when an audio signal is detected on either the line-level or speaker-level inputs. After a period of time with no signal input, the amp will turn itself off.

  • ACR-3 Remote: The optional AudioControl ACR-3 wired remote is a dual-function remote that lets you adjust both the level of the main and line outputs, as well as recalling memory presets, all from the driver's seat. The ACR-3 has two LED indicators and a rotary/push-knob. When the blue LED is on, the remote knob raises and lowers the output level. When the knob is pushed in, the red LED will light, allowing the knob to recall memory presets when turned.

  • DM Smart DSP: The D-4.800 includes a micro USB (Type-B) port to connect to a laptop (USB Type-A to micro-B cable included, allowing you to use AudioControl's DM Smart DSP app. This is a fully featured Matrix DSP interface designed to give you control over every aspect of the processor. Features include routing any input to any output, gain adjustment, delay, polarity, and a 30-band EQ. High-pass, low-pass, and band-pass filtering can be set up for any output using 12 or 24 dB/octave Linkwitz-Riley crossovers. It also includes RTAs (Real Time Analyzer) for every input and output to easily identify and sum factory speaker signals for OEM integration.

  • Top Panel: Underneath the removable protective panel are the GTO on/off switch, labeling for all of the input/output connections, and the following LED indicators:

    • Power: If the amp is powering on correctly, this should be lit green.
    • Protection: The amp has built-in diagnostic codes to tell you exactly what is going wrong if the amp detects a problem. Both the Protection and Power LEDs can flash certain codes indicating where the problem is. A chart of these is provided in the Quick-start guide.
    • Communications LED: This LED lights when there is USB activity between the amp and your computer during set up.
    • Maximized Input LEDs: These LEDs illuminate when a maximum audio signal is present on any of the analog audio inputs. Signal levels should be lowered if these LEDs are on a lot. Three LEDs are provided covering: Front High, Front, and Rear.
    • Maximized Output LEDs: These LEDs illuminate when there is maximum signal present on any of the audio outputs. Signal levels should be lowered if these LEDs are on a lot. Two LEDs are provided, one each for Outputs 1/2 and 3/4.
    • MILC Source Clip LED: The MILC (Maximum Input Level Control) level-setting circuit prevents clipping and distortion. It calculates when the waveform of an incoming signal on input 1 or 2 is clipping and lights this LED. The level of the incoming signal should be set just prior to MILC LED coming on.


  • Connections: The D-4.800's connections are aligned along the front of the amplifier for ease of installation. The amp's connections include:

    • Fuses: Two 40-amp ATO blade-type fuses are installed in the amplifier.
    • Power: Set-screw terminals are provided for connecting +12V Power, Ground, and Remote In. The Power and Ground terminals will accept 8 to 4-gauge wire, while the Remote In terminal accepts up to 6-gauge. An 80A fuse should be placed in-line on the power wire, no more than 18" from the battery.
    • Line Level Inputs: Two pairs of RCA jacks are provided for connecting the amp to the source unit via RCA cables.
    • Line Level Output: One pair of RCA jacks for feeding the signal to another amplifier.
    • Speaker Level Input: Three sets of removable Phoenix (or Euroblock) connectors are provided for connecting the source unit via speaker-level input. The connectors are labeled Front High (for tweeters), Front, and Rear.
    • ACR-3 Control: This RJ-14 telephone-type connection allows you to plug in the optional ACR-3 Remote. The ACR-3 is used to change the output level and for recalling memory presets.
    • USB: A micro-USB (Type-B) is used for connection to a computer for DSP configuration.
    • Speaker Output: Two removable Phoenix connectors are provided for connecting speaker wire. The amplifier will accept a load impedance of 2Ω or higher in stereo (4Ω or higher when bridged).
    • Option Port: A multi-pin input is used with an optional AC-BT24 Bluetooth module (sold separately). This allows both audio streaming from a Bluetooth enabled device, as well as configuration and control via the DM Smart DSP app.
