About the AudioControl Overdrive
Get maximum performance from your amps
Get maximum performance from your amps
AudioControl created the Overdrive with one goal in mind to ensure that your amp sees the cleanest signal possible. Many modern car stereos boast 4- and 5-volt preamp outputs, but they're rated at full output. Turn your stereo to a normal volume level, send the signal through a 20-foot cable, and your amps may end up with just a couple of volts. That's why AudioControl made the Overdrive.
Higher voltage = lower noise
The Overdrive line driver boosts the signal from your receiver up to 24 dB, right up to the maximum level accepted by your amplifier or processor. The high voltage level keeps the noise out of your system, while feeding your amps the signal they need to deliver top performance.
Easy adjustment
Once connected, the Overdrive makes it easy turn up the gain knobs until the light indicates 2-, 5-, or 7.5 volt output, and you're all set. Balanced inputs reject noise caused by your vehicle's electrical system, but you can switch to unbalanced operation if necessary. The Overdrive's low-impedance output keeps your signal going strong through long cable runs.

Features
Line Driver: To achieve the best possible signal to noise ratio and dynamic range from your amplifier, a line driver can increase the head unit's output voltage up to 24 dB (maximum is 9.5 volts RMS/13 volts peak).
Input Gain: The input gain is adjustable up to +24 dB, allowing you to increase the head unit's line voltage to the top of your amp's input range; up to 9.5 volts RMS/13 volts peak.
Output Voltage Indicators: As the gain is turned up, four LEDs indicate the output voltage; 2 volts, 5 volts, 7.5 volts, and Maximized (9.5 volts).
Balanced Input/Output: Using the balanced differential input circuit cancels noise picked up in the transmission line between the Overdrive and the the source unit, or between the Overdrive and the amplifier. The inputs and outputs can be individually set to balanced or unbalanced, incase your amps don't accept balanced inputs.
Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.
Terminal Block: The power/ground/remote terminal is removable; the wiring is attached to the block, then the block is plugged into the Overdrive.
