Select the line source input using either the numbered selector  buttons  (1 to 5) or the 

channel up/down arrow buttons (Please see Figure 3). 

 

Control the volume level using the right (louder) and left (quieter) arrow buttons adjacent to 

the channel arrow buttons. 

 

Mute the volume using the button labeled “MUTE”. To raise the volume again after muting, 

press the Mute button to take the volume level to where it was prior to muting. In Mute 

mode, the light above the “operate” button on the front panel of the L-10000 OTL/OCL will 

not be illuminated; it will illuminate when the L-10000 OTL/OCL is unmuted again. 

 

Use the red power on/off button in the top left-hand corner of the remote control to power 

the L-10000 OTL/OCL on and off. 

 

 

INITIAL POWER-ON 

 

Once you have your L-10000 OTL/OCL  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-10000 OTL/OCL. Before you power up the L-10000 

OTL/OCL, 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).

 

 

turned the volume down on, or muted the L-10000 OTL/OCL  

 

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-10000 OTL/OCL. 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-10000 OTL/OCL on and off. 

 

Once the power has been turned on, the following will happen on the front panel (Please see 

Figure 4): 

 

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-10000 

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