CHAPTER 2

ELECTRICAL SAFETY ISSUES

Pay close attention to these important electrical and safety 
issues.

 

CAUTION:

 Do not use a power cord adapter 

to drive the 700-HP subwoofer from a stan-

dard three-prong Edison outlet since that connector 
is rated for only 15 amps (NEMA 5-15R; 125 V AC 
max.).

 

CAUTION:

 The 700-HP subwoofer requires a 

ground connection. Always use a grounded 

outlet and plug.

TIP: 

Use the ring located in the rear to 

the side of the amplifier on the 700-HP 

subwoofer to provide strain relief for power and 
signal cables. Do not use this ring for any other 
purpose.
