Operation
NF-A1
Operation
Once you have established the connection and checked it, please switch
on the NF-A1 mains adapter using the main switch at the back (item 7).
The device is now in standby mode and the red LED (item 2) lights up.
Now switch on the other components. Switch on the NF-A1 as well, using
the standby key (item 1). The red LED (item 2) stops out and the green
LED (item 3) begins to flash.
The tubes of the NF-A1 are being warmed up and the working points are
set correctly. You might hear a gentle "clicking" from the NF-A1 driver as
well as from the NF-A1 mains adapter. This comes from small precision
relays that are controlled by the electronic units. As soon as this
procedure is completed, the green LED (item 3) stops flashing and
remains constantly lit. The NF-A1 Cable Set is now ready for use.
Note: The NF-A1 has a switch-on delay that activates the music signals
after the warming up phase. You must therefore wait until the entire NF-
A1 is ready for use (green LED - item 3 - remains lit constantly) before
starting to play music. Otherwise there is a risk that the music signals are
switched on suddenly und unexpectedly. If the volume is set too high
(volume control on the amplifier near the right stop), this can damage the
loudspeaker.
Burn in period
As with all cables and components, the new Audio Cable also needs time
to "break-in". It takes about 20 operating hours for the NF-A1 to live up
to its full sound potential. Please also note that the tubes of the NF-A1
first need to reach their operating temperature every time they are
switched on, before the full sound is generated. This takes about half an
hour.
Additional functions
In normal function the Indicator LED (Pos.3) will light up in GREEN color.
The NF-A1 however has an built-in overheat protection. Should the device
be overheated the NF-A1 will automatically shut-down and the Indicator
LED (Pos.3) will start to blink. After the NF-A1 has reached normal
temperature again it will switch into the Stand-By mode and the red LED
(Pos.2) will light up. Please note that for safety reasons the NF-A1 will not
switch on again automatically ! Simply push the Stand-by button (Pos.1)
and the NF-A1 will start again.
