Features

• High-/Low-Level Inputs: The ACX-300.4 includes four built-in 12″ RCA inputs that can accept either high- or low-level input signals. If running high-level signals, RCA to speaker-wire adapters must be used (sold separately), or the RCA connectors must be cut off and the bare-ended wire used.

  • Low-Level Input Range: 500mV – 6Vrms
  • High-Level Input Range: 1Vrms – 12Vrms

• Input Mode: A 2-way switch lets you select whether one pair or both pairs of input channels will be used to feed all four output channels.

• Crossovers: The ACX-300.4 includes two 12 dB/octave Linkwitz-Riley high-pass filters, one for Channels 1 & 2 and one for Channels 3 & 4. Both use a 3-position switch to change the crossover point with a choice of  80Hz, 120Hz, or Bypass.

• Gain Maximized LEDs: Each pair of channels on the amp includes its own Gain control to properly set the overall output level. A Maximized LED indicator is provided for each pair of channels, illuminating to let you know when the output signal has reached its optimum performance level, helping to avoid running a distorted signal to your speakers.

• 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.

• All-Weather Construction: The ACX-300.4 amp has been constructed to withstand outdoor environments and carries an IPX6 waterproof rating, making it impervious to weather. A removable cover-plate on top of the amp protects the controls and LED indicators from dust and moisture ingress. The cover-plate screws require a 2.5mm hex bit for removal (not included). All wire harnesses on the amp are built-in for added weather resistance:

  • Audio Inputs: Four RCA jacks on 12″ input cables are provided, each with protective plastic caps.
  • Speaker Outputs: Two 12″ 4-wire output harnesses are terminated in waterproof connectors. Matching 7″ harnesses with bare-ended 18ga. wires are included.
  • Power/Ground/Remote: A 12″ section of 10ga. power and ground wire terminates in a waterproof connector, with matching 7″ harness and bare-ended wire. An additional empty power/ground connector is provided, letting you build your own harness to match the amp’s power/ground connector. A bare-ended 12″, 18ga. remote turn-on wire is provided in the power/ground harness.

   

• Mounting: The AudioControl ACX-300.4 features built-in mounting flanges on either end of the amp, with two pre-drilled holes in each, allowing the amp to be mounted in a variety of locations. Four 3/4″ screws are provided for mounting.
