Rythmik Audio LVX12/FVX15 ported subwoofer Quick Guide
g
Line Level inputs
For sub output from HT
receiver/processor, one can
use either of the two (R+L)
line level inputs with 12db
LPF SLOPE switch setting,
or just LFE IN. When using
LFE IN, phase control and
crossover control have no
function. The trade-off
between using LFE IN and
LINE IN is the perceived
background noise level. For
two-channel inputs, one
should use LINE IN only.
Volume level setting is determined by
the efficiency of front speakers. It is not
an indication of whether the sub c an
play louder or not.

Bass extension switch
The bass exten sion control in FVX15/LVX12 e nables the user
Parametric equalization (PEQ)
Defeatable EQ for tackling room modes.
Please see separate application note for
proper usage. For initial setup, set PEQ
switch to “off”. Markings on FREQ knob
are at 10hz increments.

SLOPE
to customize the frequency response of the low end. It
combines multi-tune specific frequency contouring and
damping control in one switch. The damping control
determines the slo pe of roll-off and the amount of time
domain ringing. High damping provides the least amount of
time domain ringing and the most gradual roll-off curve. Low
damping provides the steepest roll-off at the low end at the
expense of added time domain ringing. There are two
positions for 1 port operation which extends to 1
LVX12 (12hz for FVX15). 1P-music uses high damping while
1P-HT uses low damping. High SPL playback should use 2
port s e ttin g . The damping in this position is low.

It is one of the most important
controls for integration with line-in

Crossover setting is a fine-tuning knob for integration. It is
useful even when one
already uses bass management. The
upper end extension of the sub is limited to avoid using the servo
subwoofer at frequencies where servo is less effective. Set to
max by default.
LPF slope setting determines the slope of crossover setting. For

The power switch has 3 positions: OFF,
AUTO, and ON. AUTO detects the input
signal and turns on the amp immediately
and turns off the amp after 45 minutes of
inactivity.

should use 12db.
