The unit applied input short design :
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
The working theory :
Without the idle input short circuit
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
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
different inputs at simultaneity.
The Debug button on rear :
Debug button on rear is for select the
display always on or auto dark while 10 seconds after user stop operate
