High Level input

Mosconi HLA-Slim
Mosconi HLA-Dual

  • High Level Adapter
  • 2 channel and 4 channel version

Overview Mosconi HLA-Slim / HLA-Dual

High-Low Adapter

As 2-channel (Slim) and 4-channel (Dual) or as 2-channel HP (High Power).

  • No plastic housing and connector, therefore very small and easy to install
  • HLA SLIM HP loadable up to 50 Watt
  • Remote output loadable with 100 mA
  • Made in Italy

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.
