Active high/low converter Helix AAC.3 HP (for OEM amplifiers)

Integrating automotive hi-fi components into existing OEM audio systems with an external amplifier is becoming more and more challenging due to the lack of preamplifier outputs or the incorporation of intelligent speaker diagnostic features. That's why the new Helix AAC.3 is here. Forget about error messages or loss of functions (e.g. fader). The ADEP.3P integrated circuit cleverly "bypasses" speaker diagnostics in factory car radios. Distorted sounds and increased THD that can occur with conventional transducers are also avoided. In addition, it does not unnecessarily load the car radio amplifier and thus reduces its current consumption by up to 70%.

Intelligent signal detection

The "Double Activation Circuit" generates a remote +12V signal to turn on connected aftermarket power amplifiers in two different ways. It either detects the DC offset on the speaker outputs of the OE amplifier, or uses an integrated, switchable signal detection with variable sensitivity. In addition, the AAC.3 HP features the proprietary Audiotec Fischer "Power Save Mode" which turns off the remote output if no music signal is present for more than 2 minutes. This is a really big advantage because many cars with "CAN" or similar bus architecture keep the sound system invisibly "alive" for up to 15 minutes. even if you have left the car in the meantime.

Ready for high definition

The AAC.3 HP generates a high-quality preamplifier signal from the speaker output signal of the factory amplifier, allowing easy connection of additional power amplifiers. Its wide frequency response of 18 Hz to 80,000 Hz guarantees excellent sound quality and makes this high-resolution converter ready for high-resolution audio reproduction. For OEM audio systems without a factory-built amplifier, we recommend using AAC.3. This is specially designed to connect directly to the speaker outputs of the factory radio.

Important features of the Helix AAC.3 HP converter

Allows easy connection of additional amplifiers to your factory sound system.
Suitable for all car radios - even those with factory-installed amplifiers.
"ADEP.3P circuit" for bypassing radiodiagnostic systems.
Microcontroller controlled music signal monitoring and remote signal generation.
"Power Save Mode" significantly reduces the power consumption of connected amplifiers when no input signal is present (after 2 min.)
"Double Activation Circuit" - generates a remote +12V signal in two different ways to turn on connected amplifiers.
Excellent sound quality thanks to a very wide frequency response (18Hz-80kHz).
High-quality, sealed and gold-plated RCA / RCA connectors for lossless signal transmission.
