RCA Analog Line-Level Inputs – The line-level output from the head unit or factory-installed radios can connect here, so the D-4.800 will receive the line-level audio signals. 2. Power Input Terminal +12V – The left screw terminal connects to the +12V battery binding post of the vehicle.
Features continued 6. USB Micro Connector – This connects to the USB A port of your computer in order to use the control software to configure the D-4.800. 7. Remote Control Connector – This connects to the optional ACR-3 remote level control using a standard telephone cord and connectors. 8. Speaker-Level Output Terminals – These screw terminals connect with speaker wire to your loudspeakers. Make sure that the average combined speaker impedance does not dip below 2 Ohms, or 4 Ohms in Bridged mode.

GTO™ Signal Sense – In the ON position, the D-4.800 amplifier will turn on gracefully when it detects an incoming audio signal on inputs 1 and 2, and it will turn off after a period of time when the audio signal fades away to silence.
System Examples Power Connections Head Unit Remote +12V Trigger In this example, the head unit has a +12V trigger output that is connected to the D-4.800 remote input terminal. When the head unit is turned on, it will turn on the D-4.800. Alternatively, the GTO™ signal sense feature can be used to gently turn on the D-4.800 when an audio input signal is detected at inputs 1-2. (Then the connection to the D-4.800’s remote input terminal is not required.

Installation Installation We recommend mounting the D-4.800 in the trunk/boot or cargo area of the vehicle. An alternative location would be under the front seat of your vehicle if there is enough room to install and also to reach the controls. When choosing a location, please keep these things in mind: 1. Before you start, disconnect the +12V positive and negative cables from the battery in the vehicle to prevent any damage to the vehicle or the amplifier during the installation process. 2.
Installation continued ACR-3 Dash Control Option Top Lid Removal The optional AudioControl ACR-3 dash control is a dual-function remote for your D-4.800. It may be mounted under the dash using its own bracket, or through a custom hole in the dash. The endless knob should be within reach of the driver, and in a spot where the two LEDs are plainly visible. Disconnect the vehicle battery +12V and Ground connections before installation.
Quick Start Quick Start Before you start, please take a moment to visit our knowledge base: www.audiocontrol.com/knowledge-base. It will help you with a plethora of sound advice, and help set the mood for the installation. 1. 2. 3. The following details give a brief overview of the steps required to install the D-4.800 in your system. The steps below are explained in more detail throughout the on-line manual.
Software Application The Display The display has three main sections: Input View, Output View, and Dashboard View, in addition to the top menu bar (File, Tools, Help) and the Memory (1, 2, 3, 4) section. For more details of the software application, please take a look at the on-line owner’s manual. Input View This display allows you to set the input gains, polarities and delays. The goal of the Input View display is to get all of the signals arriving to the D-4.
Software Application continued 14 Output View This is where you will spend the majority of your tuning time, as it is where you will set routing and summing, output levels, crossovers, EQ and AccuBASS® settings. The D-4.800 is exceptionally flexible, and can be configured to use any output in any bandwidth or source and match the needs of the installation. 1. Select an output from this list, and it will be highlighted in glorious living grey. Then all the parameters shown are for this output pair.
Software Application continued Dashboard View This display allows you to conveniently see the settings of any one input and any one output simultaneously. All of the controls work the same as the Input View and Output View.
