Power Supply for Active Ground Sound Solution
PSU8AGS is a complete power supply unit with many features for the Active Ground Sound concept.
It provides power for DCN14 or DCN22 and a number of
PA1CC and/or PA3CC and/or HPA1K
and/or HPA2K. PSU8AGS also features separate unregulated power supply rail voltages
for the digital crossovers DCN14 and DCN22.
An input sensing circuit keeps an eye on signal inputs at DCN14 / DCN22 to auto start the digital crossovers
and the power amplifiers. A switch selects between ON - STAND BY - AUTO SENSING to ease the use in daily life.
If on or signal is present this switches the big transformer relay on. The transformer ramps up the 8 pieces
audio grade capacitors (Nichicon or Panasonic) via soft start circuitry limiting inrush current to
about 7A. DCN14 / DCN22 controls the soft start circuitry and activates the full power relay after about 2 seconds.
There are two LEDs to indicate STAND BY or ON. PSU8AGS will ensure enough resources for the power amplifier
modules to easily drive, even difficult speaker impedances.
Please note: PSU8AGS and DCN14 / DCN22 are highly integrated and require each other to operate !
