The unit applied input short design but can
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 auto dark
unit can set the auto dark feature by
The 2nd display show the state
of the auto dark feature.
When it display "1", mean the
auto dark feature active, the unit auto dark after stop operate on it,
only left a little LED to display the unit is power on .
When it display "0" , mean the
auto dark feature discontinued, the unit will light on the display
always after power on it.
To change the feature, user can
turn the unit to In 3 channel, turn the volume to "0", then push the
volume down button one time to active or discontinued the auto dark
