CAUTION! Do not locate sensitive high-gain
equipment such as preampli ers or tape decks
directly above or below the unit. Because this
ampli er has a high power density, it has a
strong magnetic eld which can induce hum into
unshielded devices that are located nearby. The
eld is strongest just above and below the unit.
If an equipment rack is used, we recommend
locating the ampli er(s) in the bottom of the rack
and the preampli er or other sensitive equipment
at the top.
The lightning bolt triangle is used to alert the user
to the risk of electric shock.
The exclamation point triangle is used to alert
the user to important operating or maintenance
instructions.
