J4: Slave ON/OFF control input in 2-pin PH2.0, isolated LinearPi Pro can be controlled remotely by this slave control input. LinearPi Pro will be turned on when a 3V-12V control voltage is applied to this input. The control signal is non-polarity and optical isolated from LinearPi Pro.
LED indicators D3: Power input indicator. Indicating that the power input is applied when lit. D6: Power on indicator. Indicating that the LinearPi Pro is turned on and output voltage is applied to J5 when lit. J. Fuse The fuse is a standard 5*20mm fast-action glass fuse. The default fuse is Littelfuse 0235005.MXP The fuse can be sourced here (#60B): https://iancanada.ca/products/fuses?variant=47645175447852...
K. Load transient response measurement of a LinearPi Pro LinearPi Pro has a really great load transient response performance. The output voltage drop is only 10mV at ultra-low noise level when output current changes over very big steps between 1A to 5A. The measured dynamic output impedance is only 2.5mOhm (@1kHz), which could be the best performance among all the...

Mount a UcConditioner Pro (same voltage) on top of the LinearPi Pro by the 35mm LinearPi Pro screw/standoff sets (sold separately). b. Connect V+ and V- of the LinearPi Pro output J5 to the + and – of input J2 of the UcConditioner Pro through big power wires, 18 AWG or bigger.

3. Recommend the continuous AC input mode Though we can use AC power to turn on and turn off the LinearPi Pro (ON/OFF switch S1 has to be at ON position), for the best possible sound quality, it’s highly recommended to use the continuous AC input mode by keeping the AC input continuously powered while using the ON/OFF control switch/logic to turn on or turn off the LinearPi Pro.
