Helix AAC.3 Smart active analog converter

Integrating car audio components into the existing original sound system is becoming increasingly complex due to intelligent radio and amplifier diagnostics and the lack of preamp outputs on factory radios. This is where the Helix AAC.3 comes in.

The most intelligent high-to-low converter in its class

Thanks to the integrated ADEP.3 circuit, which bypasses the radio's diagnostic system, error messages or even the loss of individual functions (such as the fader) are a thing of the past.
Distorted music signals and increased total harmonic distortion, which can occur with conventional high-to-low converters, are prevented by the intelligent ADEP.3 circuit. Furthermore, the car radio amplifier is relieved of some load, and power consumption is reduced by up to 70%.

Smart Signal Detection

Its "Double Activation Circuit" additionally generates a +12V remote signal for switching on connected amplifiers in two different ways. It either detects the DC voltage potential on the speaker outputs of typical factory car radios or uses an integrated signal detection system with variable input sensitivity, which can be activated separately.
The "Power Save Mode," which switches off the remote output if no input signal is present for more than 2 minutes, is also included as standard. Many vehicles with "CAN" or similar bus systems keep the car radio "invisibly" activated for up to 45 minutes, even if you have left the vehicle in the meantime. High-resolution capable: The AAC.3 generates a high-quality preamplifier signal from the speaker signal of the car radio or amplifier of an original sound system, thus enabling the easy connection of additional amplifiers. Its exceptionally wide frequency response of 18 Hz to 80,000 Hz guarantees excellent sound and makes it high-resolution capable.
