The Helix AAC.3 is an intelligent high-low converter that generates a clean stereo preamp signal from your factory car audio system's speaker-level output. Its ADEP.3 circuit bypasses radio diagnosis systems, preventing error messages and function loss while reducing amplifier current draw by up to 70%. The Double Activation Circuit creates a reliable +12V remote signal using either DC offset detection or a variable-sensitivity signal sensor. A Power Save Mode switches off the remote output after 2 minutes of no input, perfect for vehicles with CAN-bus systems that keep the radio active long after parking. With a frequency range from 18 Hz to 80 kHz, this converter delivers high-resolution audio and includes high-quality potted gold-plated RCA connectors for loss-free signal transmission.
