IMPORTANT

DriveCore Install Series ampliers require Class 2 output wiring.

MAGNETIC FIELD

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.
