High Low Adapter
Improvement of HLA.2 and HLA.4
The main improvements are:
Ø No plastic case and plug, therefore very small and easy to install
Ø The double possible input power handling
Ø Remote output capability increased from 15 mA to 100 mA
Ø Of course still made in Italy like all MOSCONI products now and in the future!
Note:
HLA-Slim / Dual are able to produce a stable and useful REMOTE signal only if the headunit is an high power unit (BTL).
On these kind of headunits, each output has a steady state voltage which is used to detect when the headunit is powered on.
HLA-Slim and/or Dual need at least 3Vdc on at least one of its inputs.
These devices are not intended to sense the music signal, but only the dc voltage present on each BTL output.
