INITIAL POWER-ON 

 

Once you have your L-8000 DHT 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-8000 DHT. Before you power up the L-8000 DHT, though, 

be sure you have: 

 

 

CAREFULLY AND SLOWLY removed ALL the cardboard cushion materials from inside the 

tube chimneys

 

 

ensured the batteries are in the remote control – if not, insert the batteries (by removing 

plate on the bottom of the remote control).

 

 

selected the output connections that you want to use, single ended (RCA) or balanced (XLR), 

on the switch at top centre on the back of the preamplifier 

 

turned the volume down on or muted the L-8000 DHT 

 

checked that all your connections are snug 

 

Also, be sure you have manually turned the volume control on the front panel to the extreme 

counter-clockwise position (minimum volume). 

 

Push the power on-off switch to the left of the IEC connector (facing the left side of the unit as 

in Figure 1) so it is in the “on position”. That will power up the L-8000 DHT. From this point on, 

you need only use the far left hand button marked “power” on the front panel or the power 

button on the remote control to turn the L-8000 DHT on and off. Once the power has been 

turned on, 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 

 

the light over the line source button that is depressed will illuminate 

 

after about 40 seconds, the light over the “operate” button will illuminate. The L-8000 

DHT has a “soft start” delay for the tubes in order to extend tube life. 

 

The Allnic Audio L-8000 DHT is now ready for operation. At this point, you can power on your 

sources and, finally, your stereo power amplifier or mono-blocks.
