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. This board is especially recommended for car audio application to allow complete isolation of the alternator noise. It is compatible with all miniDSP products except the miniDSP 2x8/8x8 units.
The below diagram illustrates the timing relationship between Vin, Vout, REMin and REM out pins. 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.
NOTE: This product is unfortunately currently out of stock. We're hoping to get supply again by early April 2014.
- 12V DC to DC isolation compatible with miniDSP unbalanced and balanced units
