IMPORTANT
I-Tech Series amplifi ers require Class 2 output wiring.
Les amplifi cateurs de série de I-Tech exigent des câbles de sortie de
classe 2.
I-Tech-Reihe-Verstärker verlangen Klasse die 2 Produktionsverdrah-
tung.

MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as pre-
amplifi ers directly above or below the unit. Because this amplifi er has a
high power density, it has a strong magnetic fi eld which can induce hum
into unshielded devices that are located nearby. The fi eld is strongest
just above and below the unit.
If an equipment rack is used, we recommend locating the amplifi ers)
in the bottom of the rack and the preamplifi er or other sensitive equip-
ment at the top.
