CHAPTER 1

Theater Grand Editions

The Theater Grand seven chan-

nel power ampli

fi

 er is available in two 

editions:

•    TGA-7400          

•    TGA-7200

The TGA-7400 has twice the power 

output, and uses heavier output ter-
 mi nals com pared to the TGA-7200. 

This manual uses illustrations of the 

TGA-7400. The operational details, 
features, and con nec tions to loud-
 speak ers and pream pli 

fi

  ers are the 

same for both models.

The TGA-7400(E) and TGA-

7200(E) are export models, set for 
220-240 VAC operation. Their opera-
tion is identical to the TGA-7400 and 
TGA-7200 ampli

fi

 ers.
