The Onix Rocket UFW-10 (Ultra Fast Woofer) is a
very potent and agile subwoofer. Special care
and attention was given to the UFW to ensure
clean, accurate, and extremely detailed low-end
performance in both music and home theater
systems. Features include a 500-watt amplifier,
single band parametric equalizer, adjustable
crossover, and infinite phase adjustment for easy
in-room placement. This flexibility will result in a
seamless blend with all Onix loudspeakers, as
well as those from other manufacturers.
Section 1—Product Overview
1.1 Control Panel Features (see figure 1.1)
A. Power switch
B. Power On Indicator – Glows brightly when
the unit is on. Glows dimly when unit is
in standby. The unit will automatically
turn on in the presence of an audio signal.
Approximately 15 minutes of signal ab-
sence will cause the subwoofer to go into
standby mode. To fully turn off the unit,
please unplug it from the wall.
C. Line Fuse – The UFW-10 is equipped with
a 4-amp fast blow fuse. Always replace
with the same rating.
D. Power Cord – A standard IEC socket al-
lows removal of the power cord.
E. LFE/MONO XLR (balanced) connection. If
your preamplifier has XLR output avail-
able, use this connection.
F. Audio Inputs – Standard RCA
(unbalanced) type cables will work here.
If your preamplifier or receiver has only
one sub out, use the R (L+R Summed)
connection.
G. Crossover In/Out switch – When set to
IN, the crossover is activated. When set
to OUT, the crossover is disabled.
H. Crossover Adjustment – This controls the
high-frequency cut off. Generally this is
set to 80Hz if used. We will cover this in
detail later in the manual.
I. Phase – This controls the phase of your
subwoofer relative to the rest of your
speakers. Rotate this dial in small
amounts while you listen at your listening
position for the most bass.
J. Gain – This control allows you to match
the output of your main/satellite speakers
to the sub. Set this to the lowest level
when powering your system for the first
time. When calibrating your system, do
not exceed 75% gain. You’ll want some
room for adjustment...try to avoid setting
the gain in either your receiver (through
the channel “trim” menus) or your sub-
woofer near maximum levels. Doing so
will also minimize the potential for a dis-
torted input signal.
K. EQ – Single band parametric equalizer.
Includes controls for Frequency, Band-
width and Level. Use these controls to
modify the frequency response at any
point. The frequency range is 20Hz to
80Hz…bandwidth from 0.1 to 1.0 oc-
