Please note:
This product applies the latest regenerate power technology.
Therefore the working temperature has dropped significantly compared
to the previous generation products. This allows leaving power on
over the long term.
This product is burned-in for at
least 300 hours before shipping.
We recommend burning it
for an additional 300 hours for best results.
The quickest way to complete the
burn-in of this product is to power on it continuously, no matter
with or without music playing to the burn-in.
Do not immediately power on the unit
after powering it off. Wait for at least 30 seconds.
Connect with KRELL amplifiers'
CAST input or SATRI amplifiers' current input:
HE-1 MK3 is compatible with KRELL amplifiers CAST inputs.
A cable can be made
with one side connecting to HE-1 MK3 ACSS
outputs, other side to a KRELL amplifier CAST inputs.
The ACSS output pins:
Pin 1, GND
Pin 2, Hot
Pin 3, Cold
Pin 4, GND
The ACSS input pins:
Pin 1, GND
Pin 2, Hot
Pin 3, Cold
The XLR input/output pins:
Pin 1, GND
Pin 2, Hot
Pin 3, Cold
Button
and Knob
functions ：
Leftmost button:
Power On or Off.
Left button on left side: (Only
available while user want to change the set feature .)
Push the left button
once, the leftmost digit of bottom will blink, which indicates it is selected.
This allows changing the corresponding setting. Push the right button to select the desired value. While the display is
still blinking, push left button again , the next digit to the right
will be selected and blink.
While the rightmost digit of
bottom is
blinking, push the left button one time, quite the set menu and back to the normal
state.
Right button on left side: (Mulriple functions.)
While the display is in normal
state (not blinking), it allows selecting the input source in
decreasing order. One of the following will be displayed:
"1 - XLR"
"2 - RCA"
"3 - XLR"
"4 - RCA"
"5 - ACSS"
Knob on right:
Adjust the volume control .
Display inform ：
Display inform (In normal working state):
Leftmost on top
: Mean the gain fine turning
level ,it is from 1 to 9, every step can change 1DB gain ,9 mean the max
gain . Available with XLR and RCA
inputs, the ACSS input can't control the fine turning gain.
Left 2nd and 3rd on top : Mean the volume level, from 0 to 99, 99
is the max volume .
Leftmost on bottom
: Mean the gain
select , "H' mean the High gain 16DB , "L" mean the Low gain 6DB .
Available with all inputs.
Left 2nd on bottom : Mean the
display auto-dimming setting:
d (Auto Dark) : Enables the display's auto-dimming; the display will dim
10 seconds after the buttons are left untouched, only keeping a LED bar
lit to indicate the unit is turned on. As soon as a button is touched,
the display will turn back on.
b (bright) : Disables the display's auto-dimming, the display will remain
on at all time.
Rightmost on bottom : mean the input
channel number .
Display inform (When push the left
button into the setting state ):
Leftmost on top :
Push the left button once, the leftmost on top blinking, turn the volume
knob that can change the gain between 1 to 9, allow change the fine gain
for every input channels .
All digits on top : Push the left
button two or three times, the all digits on top show the unit inside
temperature of centigrade .
Leftmost on bottom
: When it blinking , through push the right
button can change the gain ,"H' mean the High gain 16DB , "L" mean the
Low gain 6DB . Available with all inputs.
Left 2nd on bottom :
When it blinking, through push the right button change change the
auto-dimming setting:
d (Auto Dark) : Enables the display's auto-dimming; the display will dim
10 seconds after the buttons are left untouched, only keeping a LED bar
lit to indicate the unit is turned on. As soon as a button is touched,
the display will turn back on.
b (bright) : Disables the display's auto-dimming, the display will remain
on at all time.
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.
In world there are more than 99% DACs and the sources had allow the
outputs short ,
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.
