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-9000 OTL/OCL will not be 

illuminated; it will illuminate when the L-9000 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-9000 OTL/OCL on and off. 

 

 

INITIAL POWER-ON 

 

Once you have your L-9000 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-9000 OTL/OCL. Before you power up the L-9000 OTL/OCL, though, be 

sure you have: 

 

 

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

chimneys

 

 

ensured all tubes are snugly in their sockets

 

 

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-9000 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-9000 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-9000 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-9000 OTL/OCL 

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

 GAIN STAGE BALANCING USING THE CURRENT METERS 

 

There is one current meter for each channel on the front of the L-9000 (See Figure 4). These meters 

indicate the potential for DC from the output of the third gain stage tubes in the L-9000 OTL/OCL, 

the 6080s.
