inputs are RCA type single-ended connections. None of the
switch; phase is either normal or inverted one hundred
percent, depending on the switch position. On initial
connection, set the switch to normal. Depending on the
phase your sources output and their facilities with regard to
phase, you may want to switch to inverted phase
sometimes. Phase issues generally will result in lack of bass
and/or focus of the stereo image (Please see Figure 3).

REMOTE CONTROL
The remote control provides the ability to remotely:
Power the L-4000 on and off (it is a "toggle" type
switch) using the button labeled "POWER".
Select the line source input using either the
numbered buttons or the up and down arrow
buttons above and below the CHANNEL label (Please
see Figure 5).
Control the volume level using the up (louder) and
down (quieter) arrow buttons above and below the
VOLUME label.
Mute the volume using the button labeled MUTE,
located between the CHANNEL and VOLUME arrow
buttons. Depressing this MUTE button will run the
volume control down to zero. To raise the volume
again after muting, press the MUTE button to take
the volume level to where it was prior to muting.
INITIAL POWER-ON
Once you have your L-4000 in place and all connections
have been made to your sources and amplifier(s) and the
power cord is installed and plugged into an AC receptacle,
you are ready to turn on the power for your L-4000. Before
you power up the L-4000, though, be sure you have:
removed ALL the cushion materials from inside the
tube chimneys
selected the output connections that you want to use,
single ended (RCA) or balanced (XLR), on the two
switches on the back of the phono stage
turned the volume down on or muted the L-4000
checked that all your connections are snug
PLEASE NOTE – CAUTION!
1)
You may need to depress the power switch on
the left side panel of the chassis several times
(wait 30 seconds or so between each try), for the
L-4000 to power up internally (before you turn on
the unit from the front panel or the remote
control). The boot system inside the unit needs to
recognize the remote control and synchronize
with it; this is what accounts for the possible
necessity of several tries with the rear switch.
When that operation is successful, the events
described just above will occur. Unsuccessful
boot-ups may result in some of the front LED's
glowing faintly if the power switch on the front
panel of the chassis is in the "on" position, but
this may be ignored.
2)
Be sure you have manually turned the volume
control on the front panel to the extreme
counter-clockwise position (minimum volume).
OPERATION
When the Allnic L-4000 has powered up internally and
you have either depressed the far left hand button
marked "power" on the front panel, or pressed the
power button on the remote control, the following will
happen on the front panel (Please see Figure 5):
The light above the "power" button will
illuminate.
The meters on the front panel will illuminate.
Any of the five numbered line source lights that
are depressed will illuminate.
After about forty (40) seconds, the light above
the "operate"/"mute" button will illuminate. The
L-4000 has a "soft start" delay for the tubes in
order to extend tube life.
The Allnic Audio L-4000 is now ready for operation. At
this point, you can power on your stereo power amplifier
or mono-blocks.
To avoid surges to the speakers, it is best to change from
input to input only with the "operate" button set to mute
(the light above the button will not be illuminated when
the button is in the "mute" position).
