Helix AAC.3

Helix AAC.3 on uusi paranneltu versio suositusta Helix AAC.2 linjamuuntimesta.

Helix AAC.3 on todella laadukas aktiivinen 2-kanavainen linjamuunnin joka ei kavenna
taajuuskaistaa passiivisten linjamuuntimien tavoin. Tämä linjamuunnin on oiva apu
tehdasasennetun autoradion kaveriksi jossa ei ole RCA-linjaulostuloa saatikka
herätettä vahvistimelle. Helix AAC.3 heräte ulostulosta saa herätteen
vahvistimelle kun kaiutinlinjoihin tulee jännite ja se muuttaa
kaiutintasoisen signaalin linjatasoiseksi (RCA).

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 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.
