Controls/adjustments
the 4319 has front-panel adjustments that let you balance the levels of the
midrange driver (labeled MF) and tweeter (HF) against the woofer.
You can use these controls to adjust the speaker’s sound according to
your room’s acoustics or your personal taste. The 0dB positions are indi
-
cated on the unit.
as with most speakers, after you start playing the 4319 it will take the
drivers’ suspensions several weeks to “break in” and achieve optimum
performance. during this period, the balance among the woofer, midrange
and tweeter may change, so we recommend that you adjust the
midrange and tweeter controls accordingly.
Caring for Your speakers
• Wipe the cabinet with a clean, dry cloth to remove dust. Damp cloths or
cleaning paper may dull the cabinet’s finish. Do not use volatile liquids
such as benzene, thinner or alcohol on the cabinet.
• Do not spray insecticide near the cabinet.
• To remove dust from the grille fabric, use a vacuum cleaner set
to low suction.
• Do not wash the grille in water, as this may fade the colour or make
it uneven.
• If the surfaces of the woofer and midrange cones become dusty, you
can carefully sweep them clean with a soft, dry calligraphy brush or paint
brush. do not use a damp cloth.
• NEVER touch anything to the tweeter dome.
