HL4 PRO 4-channel Active Signal Converter

An easy to use OEM interface to connect amplifiers without Hi-Level input to any source unit with analog outputs.
But the HL4 PRO is not just another active hi to lo converter... The Hi-Level input circuitry is identical as in our DSP PRO.
And the outputs feature a level adjust switch to easy match the HL4 PRO with higher or lower output source units.

Features

  • Active four channel speaker level to line level converter.
  • Auto sensing on high level inputs, auto turn on/off.
  • Remote output for switching on/off amplifiers.
  • 2 or 4 Channel input selection switch.
  • High or Low level RCA output selection.
  • DC Offset / Audio signal, turn on selection switch.
  • “Ultra Low Distortion” design with 5V RMS output levels.
  • “Super Wide Range” frequency response.
