CAUTION
Magnetic Field
CAUTION: Do not locate sensitive high-gain equipment such as preamplifiers or tape decks
directly above or below this unit. Because this amplifier has a high power density, it has a
strong magnetic field which can induce hum into unshielded devices that are located nearby.
This field is strongest just above and below the unit. If an equipment rack is used, we
recommend locating the amplifier(s) at the bottom of the rack and the preamplifier or other
sensitive equipment at the top.
The lightning bolt triangle is
used alert the user to the risk
of electric shock.

1. Read all the SAFETY INSTRUCTIONS before using the product.
2. This product must be earthed. If it should malfunction or break down, grounding provides a path of least
resistance for electric current to reduce risk of electric shock.
This product is equipped with a cord having an equipment-grounding conductor and a grounding plug;
The plug must be plugged into an appropriate outlet that is properly installed and earthed in accordance
with all local codes and ordinance.
DANGER- Improper connection of the equipment-grounding conductor can result in a risk of electric
shock.
3. Do not use this product near water - for example, near a bathtub, washbowl, kitchen sink, in wet
basement or near a swimming poor or the like.
4. This product should be located away from heat sources such as radiators, heat registers or other
products that produce heat.
5. The product should be connected to a power supply only of the type described on the operating
instructions or as marked on the product.
6. The power-supply cord of the product should be unplugged from the outlet when left unused for a long
period of time. When unplugging the power-supply cord, do not pull on the cord, but grasp it by the
plug.
7. Care should be taken so that object do not fall and liquid are not spilled into the enclosure through
openings.
