DEDICATED &
ACOUSTICALLY
ISOLATED
BI-AMPLIFIER

The NF-1A features a fully
independent bi-amplifier with
60W of independent power
available for both the Low and
High frequencies. This ensures
that each unit is driven in perfect
electrical isolation. The amplifier
is also cleverly installed ensuring
that unwanted vibrations are kept
to an absolute minimum.

R-CORE TRANSFORMER

The large sized R-core
transformer supplies more than
enough power to ensure that the
Low frequencies maintain their
integrity - even at high sound
pressure levels.

FLEXIBLE FILTERING

Adjusting filters include LO FREQ
(+3, 0, -3dB @ 60Hz),  HI-MID
ATT (0, -3dB) and HI FREQ (+3, 0,
-3dB). An independent tweeter
control (-3dB to +3dB variable)
is also present. Crossover point is
set at 5kHz).
