The unit applied input short design :
         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.

OUT Button :
          Select the Master 19 output model  , display "H" mean for headphone output, display " P" mean for preamp output.

Gain Button :  
         
The L gain mode has 16DB gain, for drive the headphones which have over 100DB sensitivity or work as preamp.
         The H gain mode has 25DB gain, for drive the headphones which have 80-100DB sensitivity.

        
We have applied the new gain technology ,no any switches, relays or parameter of the amp change while change the gain modes so the sound quality is exact same in different gain modes. Users just want to choice the better mode for easy adjust the volume level.

Input Button :
          Select the Master 19 inputs from IN 1 to IN 5.

Volume knob :
          Select the Master 19 volume control .

        The left first digital number means the remote function setting, if it set to 0, whether long or short push the remote controller volume button, the unit volume only change 1 step . If set to 1, push and hold the remote controller volume button, the unit volume change continuously .In case if set to 1 but the unit had control by other devices , set to 0 please.

        The left second digital number is for set the auto dark. Set to 0, the unit display always lights while power on. Set to 1, the unit auto dark after around 10 seconds while the unit power on and without operate any buttons, there is only a LED has light for show the unit power state.

        The right first digital number for set the volume memory function. Set to 0, the unit has not volume memory . Set to 1, the unit has volume memory even restart .
