• 

Provide adequate ventilation. Do not operate on carpet or any other surface that 

might block air flow. The chassis will become warm in normal use! 

• 

Do not allow the chassis to touch any metal parts, such as the frame of an equipment 

rack. This might create a parallel ground path that could degrade the sound of your system. 

• 

Input connection is via XLR jacks.  

• 

Connect the input and speaker cables.

• 

Connect the power supply to the power source indicated on the voltage selector 

card (visible by the main fuse), either 115 or 230 volts AC. 

You may select what voltage to 

use  by  means  of  the  removable  selector  card  located  behind  the  fuse  in  the  power 

connectors. Remove the card and reinstall so that the desired voltage may be read

; be 

certain to change the fuse to the correct value. Connect the power supply to the power 

source indicated on the rear panel. Avoid power conditioners that float the ground pin. 

ALWAYS connect power cord to component before plugging it into an AC outlet, and 

make sure that unit's power switch is set to the "OFF" position before making the final 

connection. For best performance, try to route the power cord away from signal cables. 

• 

Power requirements are approximately 380 watts per channel. Pay close attention to 

power quality, and be aware that different power cords can alter the sound.
