MAGNETIC  FIELD:   !!CAUTION!!  Do  not  locate  sensitive  high-gain  equipment  such  as  p r eamplifiers  or  tape  decks  di r ectly  above  or  below  the  unit.  Because 
this  amplifier  has  a  high  power  densit y ,  it  has  a  st r ong  magnetic  field,  which  can  induce  hum  into  unshielded  devices  that  a r e  located  nearb y .  The  field  is 
st r ongest  just  above  and  below  the  unit.   If  an  equipment  rack  is  used,  we  r ecommend  locating  the  amplifier(s)  in  the  bottom  of  the  rack  and  the  p r eamplifier 
or other sensitive equipment at the top.
