Align the tabs (3 places) on the back side of the grille
with the corresponding notches in the unit, then rotate
the grille to full stop in the direction indicated by the
"LOCK" arrow.
Tip
The front grille employs a double-locking system that
clicks into place once partway through rotation, but
only locks into position at its point of full rotation.
Always be sure to rotate the grille to its full stop.

Important
Never set this switch to low impedance (8
Ω or 16 Ω) when using a high impedance 25, 70, or 100 V
line. Failure to follow this instruction could result in damage to the speaker or amplifier.
Step 7. Set the input power.
Turn the input selector switch (on the unit's front) to set it to the desired input impedance using a
slotted screwdriver.
Note: The switch is factory-preset to 330
Ω.
