GENERAL CONNECTIONS

  

 
 

A.C. LINE 

 

 Insert the linecord into the A.C. receptacle on the rear of the unit.

 PLEASE MAKE SURE 

YOU HAVE PREVIOUSLY HOOKED UP THE SPEAKERS AND PREAMPLIFIER TO 

YOUR AMPLIFIER BEFORE CONNECTING THE AC POWER CORD TO THE 

AMPLIFIER. 

 

                                                   

CAUTION:  SAFETY INSTRUCTIONS

 

 

DISCONNECT AC LINE CABLE WHILE MAKING ALL CONNECTIONS. "FLOATING THE 

GROUND” OR DEFEATING THE GROUND ON A 3-PRONG LINECORD MAY CREATE A SHOCK 

HAZARD. CONNECT ALL INTERCONNECT CABLES BETWEEN THE ELECTRONICS BEFORE 

CONNECTING THE A.C. LINECORDS TO THE WALL OUTLETS. THIS WILL REDUCE THE POTENTIAL 

SHOCK HAZARD.   
 
 

 

STEREO 

 

Input and output connectors are clearly marked on the back of the amplifier.  Left/Right 

connections are oriented from the front of the unit. Stereo output connections are marked above the 

connectors.  Switch stereo/mono switch to [UP] position.  (Units preset at factory for STEREO.) 

 

Use only high quality interconnect and loudspeaker cables, and make all connections tight. If 

the input plugs are loose, remove them and pinch down the ground leaves slightly with pliers. 

Observe correct phasing of the loudspeaker connections, and tighten.
