Product description

The AAC.3 HP - smart 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 hi-fi components into existing OEM sound systems with an external amplifier becomes more and more challenging as today's lack of preamplifier outputs or incorporate intelligent speaker diagnosis features.

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

The AAC.3 HP 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.3P 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. Additionally it 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 aftermarket power amplifiers in two different manners. Either it detects the DC offset on the speaker outputs of the OE amplifier or it utilizes an integrated, switchable signal detection with variable sensitivity.

Furthermore the AAC.3 HP 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 sound system invisibly "alive" for up to 15 min. even if you have already left the car meanwhile.

High Resolution-ready

The AAC.3 HP generates a high-quality preamplifier signal out of the speaker output signal of a factory amplifier and thus allows the easy connection of additional aftermarket 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.

For OEM sound systems without a factory assembled amplifier, we recommend using the AAC.3. This is specially developed for the direct connection to the speaker outputs of the factory radio.

Compatibility

Suitable for all OEM sound systems with a separate amplifier and a maximum output power of 155 Watts.
