Product description

The AAC.3 - active analog high-low converter by the manufacturing company HELIX is a signal converter for generating preamp signals from highlevel speaker signals of the OE car radio.

The integration of car hifi components into existing OEM sound systems becomes more and more challenging as today's factory radios either lack of preamplifier outputs or incorporate intelligent speaker diagnosis features.

That's where the new Helix AAC.3 comes into play.

The AAC.3 is more intelligent than any other signal converter on the market today.

The smartest high-low converter in its class

Forget about error messages or loss of features (e.g. the fader) - the integrated ADEP.3 circuit cleverly "bypasses" the speaker diagnosis in factory car radios. Distorted sounds and increased THD which may occur with conventional high-low converters are prevented as well. The good thing is that the ADEP.3 doesn't load the car radio's amp unnecessarily and therefore reduces its current draw by up to 70 %.

Smart signal detection

Its “Double Activation Circuit” generates a +12 V remote signal for turning on connected power amplifiers in two different manners. Either it detects the DC offset on the speaker outputs of the OE car radio or it utilizes an integrated, switchable signal detection with variable sensitivity.

Furthermore the AAC.3 incorporates Audiotec Fischers proprietary "Power Save Mode", which turns off the remote output if no music signal is present for more than 2 minutes. That's really a great advantage as many cars with "CAN" or similar bus architectures keep the radio invisibly "alive" for up to 45 min. even if you have already left the car meanwhile.

High Resolution-ready

The AAC.3 generates a high-quality preamplifier signal out of the speaker output signal of a factory radio or amplifier and thus allows the easy connection of additional power amplifiers. Its wide frequency response of 18 Hz up to 80,000 Hz warrants excellent sound quality and makes this high-low converter ready for High-Res audio reproduction.
