Please Note:
1,      If you have not a good DAC or good source, only plan to use with the PC soundcard or  cell phone, this product is not suite you.
2,      For get the product best performance, you must connect with a good balanced source ,good balanced headphone  and hi-end speaker.
3,      The metal remote need assemble two AAA battery by customer because the either DHL and UPS limit shipping by plane.

The unit applied input short design but can disable:
         The unit  had design the analog idle input short circuit for avoid the disturb between different sources.
         This design also applied in a lot high end brand devices.
         The working theory :  Without the idle input short circuit ,if the input 5 and input 4 had connect two extra DACs,  while users select the either input 5 and input 4 , the another input signal will fire through the circuits and mix  into the using signal, even though this signal is  weak  but still can degrade on the sound quality.
          With the idle input short circuit function : if user select either the input 5 and input 4, the another input signal will short circuit then no any signal fire through circuits , can keep the sound quality had not degrade.
         Below case users don't want the idle input short circuit function, users can open the chassis, pull off the jumpers of the proper input channels, please note must pull off of left and right channels together :
        1, The same extra source not only connect the unit analog input, but connect with other amps simultaneity.
        2, The same extra source connect to the unit different inputs  at simultaneity.

the left 1st display blink, push the "HP/Pre" button, the left 1st display change between " H" and "T" .
         "H" mean the sound  neutral headphone output mode.
         "T" mean the sound tubelike headphone output mode.(When the sound tubelike mode set, there is a little LED light on the right bottom of the left 1st display , and the select will be memory, evey time switch between speaker and headphone mode, it always set the tubelike for the headphone output mode, unless customer set it back to sound neutral mode.)





         When the Master 9 at the headphone output mode, push the "HP/Pre" button one time, the left 1st display blink, if not push the "HP/Pre" button gain , 2 seconds later it set to speaker output as below photo.
          When the Master 9 at the speaker output mode, push the "HP/Pre" button one time, it change to headphone mode direct without delay.

Set high/ low gain mode:
         The Master 9P can set the gain to high gain mode (34DB) or low gain mode (20DB).
         Push the "Gain" button, the left 2nd display blinking, don't push the "Gain" button again when it blinking, 2 seconds later the gain mode change .
Set the auto dim mode:
        When push the "Gain" button, the left 2nd display blinking, at this time push the " Gain" button again, there is a little led light or dark at the right bottom of the left 2nd display, the led light mean the auto dim mode active , dark mean the auto dim mode disable.

          When the auto dim mode active and no operate of the Master 9P,around 10 seconds later, the display dark.
