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 justLFE IN. When using
LFE IN, phase control and
crossover controlhave 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 can
play louder or not.
Crossover settingis a fine-tuning knob for integration. It is
useful even when onealready 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
two-channel,one shoulduse 24dbwhereas for HT input, one
should use12db.
*Delay/phase control
It is one of the most important
controls for integration with line-in
and no external delay time
adjustment control.Seeour

Power LED indicator
The power switch has 3 positions: OFF,
AUTO, and ON. AUTO detects the input
signal andturns on the amp immediately
and turns off the amp after 45 minutes of
inactivity.
Bass extension switch
Thebass extension control in FVX15/LVX12 enables the user
to customize the frequency response of the low end. It
combines multi-tune specific frequency contouring and
damping control in oneswitch.The damping control
determines the slope of roll-off and the amount of time
domain ringing. High dampingprovides the leastamount of
timedomain ringing and the mostgradual 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 14hz for
LVX12 (12hz forFVX15). 1P-musicuses high damping while
1P-HTuses low damping. High SPLplayback should use 2
port setting. The damping in this position is low.
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.
