PRESET
ORIGINAL: corresponds to the typical FBT sound. It is the default general
purpose preset and is thus fit for the majority of applications.
DEEP: this preset extends and emphasizes the low range of the
subwoofer, for a very deep and soft sound suitabie for high quality and
medium energy applications, such as acoustic music, jazz, etc.
PUNCH: the sound of the sub becomes drier, reduced low frequency
extension but more energy concentrated in the 80- 120Hz range.
Suitable for rock music and high SPL applications.
INFRA: the filter is set to a lower frequency with respect to the other
presets, thus only very low frequencies are reproduced. Use this preset
in systems with multiple subwoofers playing different frequency ranges.
For subwoofers combined with the MUSE 218SA model, select the preset
“XXXXX WITH INFRA”.

CONTROLS & FUNCTIONS
PRT / LMT: if this led light up there is a system malfunction due to an
internal amplifier failure or to the intervention of current limiting circuits
against thermal overload.
LED STATUS:
• VERDE : ON , system is in operating mode.
• YELLOW: STANDBY, in the absence of an input signal, after 30
minutes the amplifier goes into low power consumption mode. As
soon as the signal exceeds the detection threshold, it returns to
normal mode in less than 1 second.
• RED: FAN ERROR: signals an anomaly state of the fan that does
not allow the amplifier to cool adequately. Check if the fan is free to
spin, the fan may need to be replaced.
VHA 112: put the button on “YES” only when the HORIZON system also
includes the VHA 112 version, in this way by means “ALL PASS” type
filters, the perfect phase alignement between the two subwoofers is
guaranteed.
LEV: adjusts the signal general level.
PRESET: select 8 preset each of whom corresponds to a specific speaker
equalization according to user’s personal preferences and to the
acoustics of the listening area.
DELAY: contral of a digital Delay line acting on the input signal; in this
way it is possible to make up for the vertical misalignment of sub and
satellite; the Delay is expressed in meters and goes from “O” to “3,5”mt.
IN / LINK: balanced input/output socket; “IN” allows to connect a pre
amplified signal such as that coming, for instance, from mixer output;
“LINK” allows to connect multiple speakers to the same signal.
