miniDC Isolator

miniDC isolator is a tiny board allowing a perfect system integration with power on/off of your DSP and amplifier system. Based on a DC-DC isolated converter and delay circuit, it allows you remote turn ON/OFF in the correct order. Especially recommended for noisy power supply or car audio environments, this board is  compatible with all miniDSP except the miniDSP 2x8/8x8 units.

When the remote input (REM in) goes high (above 5V), the device will the isolated 12V output immediately (no delay). The remote output (REM OUT) is delayed by 3 seconds to allow for the DSP to settle before amplifiers are turned on. Once the remote input (REM in) signal goes low, the remote output goes immediately low to turn the amplifier off  first. The isolated 12VDC out will be delayed to turn the miniDSP last. For further technical details and timing diagram, please consult the product datasheet.
