Unique product! High-to-low converter with a real analysis of the audio signals - special designed to work with D-class and digital type of amplifiers (beside of usual 6V-level audio signal) to enable use it in cars with advanced audio systems (like Dynaudio, MarkLevinsot etc.). Most of “High to Low converters” works ONLY with TDA-type-of-amplifier output audio signals (6v half-voltage).This product allow to get a high quality RCA-type audio signal and remote output from these type of audio systems to feed a external after-market amplifier(s) for acoustics or sub-woofer.

For Sale is a 4-channel Hi to Low converter with "remote" for external amplifier ("remote by sound dual").

• Hand crafted. 100% designed and made in EU(Latvia). Fully digital to ensure a highest level of quality.Completely new and unused product. All 100% tested. The look is exactly like in the photo. 2ch and 4ch available. Now you are looking a 4-ch version.

   

   

  Purpose:

  1. Level conditioning 10V → 1V (60 VP-P → 6 VP-P)

  2. Signal detection:

  a) ~ 6V on Left speaker line

  b) sound signal in any channel, low level detection

  3. “REMOTE” amplifier activation

  4. Ground loop isolation between High-Level and Line-Out.

   

  Parameters:

  1) Power consumption in sleep mode 250 µA (0,25 mA).

  2) Power consumption in active state 8 mA (12 mA for 4 channel version).

  3) Output “REMOTE” can drive up to 700 mA.

  4) Wake up delay 200-300 ms.

  5) Delay before “REMOTE”output deactivation is 10 seconds after falling of 6 V on loudspeakers' lines or ~ 4 minutes after sound signal disappearing (if 6 V was absent).

  
  

  -> Used to connect amplifiers to a advanced modern OEM (original) car audio system. The adapter converts the high-level output from the radio (signal from the speakers) to a linear signal (RCA), which can be fed to the input of a non-standard (aftermarket) amplifier. 

     The main difference from other similar products is the real analysis of the audio signals !
